SUBJ: Sybase Marketing Seminar Trip Report

On Tues. June 9, John Hill, Andy Mahler and I attended one of the first
Sybase free marketing seminars at the Copley Plaza in Boston.

For those of you who don't have time to read this entire report, I will
summarize my reactions:

 o The company who has done such a good job of getting quality press
   coverage and who delivers a clear concise marketing message and who
   can boast a highly experienced and impressive management team didn't
   look nearly so good in person.  Five spokespeople from around the US
   took questions at the end of the seminar.  Answers ranged from "don't
   know" to "will be in a later release" to real hedging on their
   performance claims.  John's apt assessment was that their immaturity
   really showed through at the end.

 o It appears to me that coming late to the market, they looked around and
   carefully selected features that are currently "hot," incorporated them
   into the product and now market the hell out of them.  Examples are
   2-phase commit, stored procedures and referential integrity with
   cascading deletes.  However, when you look beyond the hot features and
   marketing hype, there are a lot of significant holes.  Some of the 
   missing pieces are embedded SQL, large selection of precompilers,  
   replication, field deletion capability, data location transparency, and 
   an extensive support organization.


The format was very similar to what RTI and Oracle use - continental 
breakfast, intro, overview presentation, demo, Q&A. Attendance was
approximately 150.  Sybase has scheduled approximately 14 of these across the 
US this year.

I saw most of the name tags during the break.  None were current Digital
database customers.  I did overhear one say to a colleague, "This is just a
lot of hype." 

Presentation
------------
Presentor was Rick Schaeffer, Director of Marketing

Sybase's corporate message is that they provide an industry standard
SQL relational database for the major hardware environments for online
applications.

They define online (vs. decision support) thus:

		Decision Support		Online

Application	query				transaction
Description	retrieval			update
		ad hoc				pre-defined

--------------------------------------------------------------------------------

Application 	Performance			Performance
Environment	  < 10 users			  10s - 100s of users
	 	  < 300 MB			  300MB - multi-GB
		Integrity desirable		Integrity mandatory
		Downtime acceptable		High availability needed
		Single machine			Networked environment



They describe their architecture as "requestor/server" or "client/server."

The 2 main products that compose their offering and their primary functions are:

DataToolset  (applications)		DataServer  (database server)
-----------				----------
interface				SQL query processing
application development			security
operation and db admin			txn mgmt
					recovery

Both can be located on 1 CPU or a system may be configured with dedicated 
servers with applications running elsewhere on the network.  They 
characterize the 2nd approach as being like a "database machine on general
purpose hardware." 

current platforms			future plans
-----------------			------------
- VAX/VMS				- MVS
- SUN/UNIX				- VM
					- PC w/ OS2 running the server, older
					  AT, XT machines running the toolset
					- other UNIX (Stratus, Pyramid)

Wide portability is not a goal.  They are clearly targeting the "Big 5"
platforms.

Sybase lists 5 features that they claim differentiate them from the 
competition:
	- High volume performance
	- Distributed Data Management
	- Window-based tools
	- High availability
	- Database-enforced integrity

High volume performance
-----------------------
Many users
Large databases
High TPS rates

It is interesting that when a customer asked what their largest database is
and what is the highest TPS rates they're getting, their answers were:
- The databases are still being developed, but we're targeting 10GB.

Note that VAX Rdb/VMS V3.0 which is scheduled to ship in 1 year is targeting
more like 20-30GB.  Our customers have already built hundreds of applications 
which will immediately be able to take advantage of the multi-file 
capability which will allow for much larger databases.

- No relational vendor will specify TPS rates. 

Note: Then how do they know theirs are higher?

- Their customers have requested that they not disclose information about
  the applications they are developing.

Note: the question was not about the applications, simply the size.  The
questioner did not care who the customer was.


Mr. Schaeffer claimed that the reason other relational databases are slow is 
because:
- Performance was not a high priority when they were developed.
- They all use too much memory.
- They rely too much on the operating system for scheduling, task switching 
  and locking.
- They don't use precompiled queries.
- Poor CPU utilization.

Sybase claims that they solve the problem thru use of the multi-threaded 
DataServer, stored procedures and because they have a database kernel that 
does scheduling and locking.  They claim that they can support 50users/MB of 
memory.

They really emphasized the stored procedure concept.  The stored procedure 
supports:
multiple SQL stmts
begin/end/abort txn
temporary variables
monitors time events
sends msgs to application
does table manipulation and conditional testing

They claim that where other companies' precompilers send interactive SQL 
command to the backend at runtime, Sybase stored the compiled procedures
in the back end and invokes as procedure txns.

Their integrity sounds very similar to Rdb, except that they do support 
cascading delete.


High Availability
-----------------
Their high availability features seem to fall short of VAX Rdb/VMS.  The 
definition of high availability was simply that users, developer, operators,
and the database administrator (DBA) could all be doing their particular
kind of work simultaneously.  The DBA could be doing perforamnce tuning
and database design while the users were accessing the database.  A customer 
immediately zeroed in on an item with which he has obviously had a problem
in the past: did they allow column add/delete without restructuring.
answer: no
(The capability has been in VAX Rdb/VMS since V1.0).
That pretty much killed the glib claims on the slide.
It was interesting to me that they never mentioned the VAXcluster.  Full 
support for the VAXcluster is a key element in high availability.  Because
it was not mentioned, I will infer that it doesn't exist.  As far as we can 
tell, VAX Rdb/VMS is the ONLY relational database on the VAX that provides
full VAXcluster support including use of the VMS distributed lock manager
to allow automatic rollback WITHOUT manual intervention.

Distributed data management
---------------------------
defined as:

	distributed access		distibuted database
	------------------		-------------------
						|     |-----------|
app ------|				app ----|     | server    |
          |---- server				|-----|		  |
app ------|				app ---	|     | server    |
           					      -------------

Languages supported: C, Fortran, Cobol

They stated that their corp mission is to porvide industry standard SQL in 
many h/w environments for online applications

They currently have 11 slaes offices in the US and they are in the process 
of establishing 1 in Europe.  The company now has over 100 people.  The 
customer base is 35.  THAT IS COMPARED WITH 3700 LICENSES SOLD FOR 
VAX Rdb/VMS.  The product started shipping Oct. 1986.

Customers include:
Wells Fargo
Chemical Bank
JPL
TRW (who is an investor)
Pac Bell

The presentation was followed by a demo of APT-FORM, which is very similar
to VAX RALLY and Data Workbench, which is very much like VAX TEAMDATA.

Data Workbench builds SQL commands at the bottom of the screen, like 
TEAMDATA.  It includes a run command on the menu.
As user is working, last 20 executed commands are saved, which can be 
retrieved, then compiled and saved.

That was followed by a Q&A session, which was the most interesting part of 
the seminar.  As with the Ingres seminar, MANY questions focused on the
dictionary capabilities.  Five representatives from around the US were
on the panel answering the questions.

Q  Can the form be designed before the database?
A  Yes

Q  Can the form elements be taken from the dictionary?
A  Yes

Q  Can you get a list of all forms containing a particular data element?
A  No

Q  Does APT-FORMS support conditional processing?
A  Yes, based on the value entered for a field, you can call another form,
   or exit (similar to VAX RALLY).

Q  Can you see the optimizer plan?
A  Yes, if you are using SQL (as opposed to 4GL).  It shows how indexes 
   are used, how joins are done, etc.

Q  How big can a stored procedure get?
A  32K bytes

Q  What prevents modification of a table containing fields referenced
   in stored procedures?
A  The speaker talked, but avoided the question.  It was rephrased, still
   not answered, and then repeated by a second person, again not answered.
   Either their integrity mechanisms aren't what they claim, or the 
   people on the panel just were not up to speed.

Q  Does Sybase allow field deletion?
A  No.  They suggested that you could create a VIEW of a record which
   does not contain the field you don't want, or you could create a
   new database without the field and copy the old data over.
   This is a good example of where they don't have basic relational database 
   capability that we take for granted.

Q  Can you interrupt a screen browse using Data Workbench and then return
   to where you left off?
A  Yes

Q  Is the data dictonary global?  How does a user know the location of
   tables?  
A  Currently the location must be contained in the program.  They are
   working... on building in location transparency (which will be in
   VAX CDD/Plus V4.0).

Q  Does Sybase support horizontal and vertical partitioning?
A  Planned for next release (about 1 year).

Q  Does Sybase support embedded SQL in host languages?
A  No.  They are working... on it.  Currently called procedures are used.

Q  When a user is entering data on a form, does  he have to go in the order
   that fields appear on the form?
A  Don't know

Q  On form create, can you get a list of all fields and their 
   characteristics?
A  Don't know

Q  How is data returned to an application?
A  A row at a time

Q  Does the DataToolset run on MS-DOS?
A  That is planned for 6-9 months.  DataServer will run on OS2 in 12 months.

Q  What network support is provided?
A  DECnet and TCP/IP

Q  What is max record size, and flds/record?
A  max record size=2K
   max flds/record=250
   They are working on a text data type for release within the next year.

Q  If you drop an index, must you change the stored procedures?
A  The first time the stored procedure runs, it will recompile.  In this
   case the path will be based on the new index structure.

11.1Be honest...BMT::NGThomas K. Ng (334-2406)Tue Jun 30 1987 23:3653
    Re. -1

    It was a very thorough report on SYBASE, except that I feel it is
    a little bias toward RDB.  I work in the New York office and, to
    be honest, RDB is not selling too well here, or not as well as
    it should be.  Our customers are constantly asking us for an 
    alternative, so I have to look at other third party packages
    in a more objective manner.  Actually, I think product management
    and engineering should also examine our competitor by asking
    ourselves, "in which areas are they better?" rather than just
    searching for deficiencies in other products to boost our egos.
    It is always easier to say we are better than to say we need
    some improvements.  Therefore, let me be the devil, and respond
    to some of the criticisms.  Also, I want to let you know that
    I have worked in ACMS development for a few years before I
    came down here, so I am very pro-VIA in general.
    
    I was involved with SYBASE because one of my customer read
    some of their propaganda in a trade journal, so they want to
    see if SYBASE can solve their problems.  I read the SYBASE manuals
    and visited the SYBASE corporate office at Berkley two weeks ago.
    We met with a whole gang of their managers, including Mark Hoffman, 
    SYBASE's President, and Robert Esptein their Exec. VP who is 
    also the chief designer of SYBASE.  My customer will get a copy
    of SYBASE in August to run some performance tests and do some
    detailed features evaluation.

    Overall, I think SYBASE is a good product.  It showed excellent
    performance when I played with it on their MicroVAX.  It did
    512 insertions in about 18 CPU seconds and with less than 300 I/O's!
    I didn't look at the elapse time because it was running on
    a timesharing VAX with about 20 other users.  Given that those
    were sequential inserts of record size of 512 bytes, it may
    not provide that kind of performance in a real life situation,
    but which benchmark is real?

    Vicki is right that SYBASE has the "hot" features like stored
    procedures and compiled queries.  However, I don't think that's
    just marketing "hype".  Those features happen to be what our
    customers want for better performance.  I don't see anything
    wrong with that.

    Of course, SYBASE has it shares of deficiencies, but you have
    to understand the fact that it is a new product.  My feeling is
    if they are going to be around next year and can deliver all
    the features they promised in the next release, they will be
    a major player in the relational DBMS market.  I am really
    impressed with their organizational and support structures.
    And Bob Esptein is extremely good!

    So, don't be too relax...

11.2Specialization has its benefitsNOVA::BERENSONRdb/VMS - Number ONE on VAXWed Jul 01 1987 16:1612
We sure aren't relaxed.  It was just nice to see that SYBASE has some warts.
It is a highly specialized, rather than general purpose, product.  For
some customers, the specialization may be desirable.

As for Rdb/VMS not selling well in NY, I blame that on NY.  No VIA
product sells well in NY.  We've done some comparisons of the Rdb
customer list and discovered that Rdb sales in the NY districts are
pitiful compared to other (smaller!) districts.   The same appears to be
true of ACMS.  Rdb/VMS is now the #1 selling relational database product
on VAX (according to Computer Intelligence Corp).  We are working hard
to keep it #1, and expand our marketshare.  Some day the financial
industries may even catch on.

    	Hi Tom (ala "one from New York")!
    
    	I'm on the 8th floor at One Penn Plaza.  let's discuss NY's
        database preferences further...
    
    re .3
    
        CIC is a wonderful source for finding out whether anyone has
    	a presence in the DEC marketplace but its accuracy is something
    	of another matter.
                          
    	In June 1986, latest insight into VAX/VMS relational database 
    	martketplace was as follows:
    
    		35%  INGRES (RTI)
                28%  Rdb (DEC)
    		22%  Oracle (Oracle)  
    
    	Other points.  
    
    		Oracle down from 25% in 1985.
    	        DBMS was also present but not included (appeared that
    		over 40% DBMS was no longer in use.)	
                
    	Sybase is clearly positioned to as a "up-and-coming" player.
    	Here are some quotes mentioned in the above reports:		
                
    	"By simultaneously (in May) making its initial product introduction
    	and achieving a blockbuster pact with Microsoft, Sybase has
    	become a highly visible player in the relational DBMS marketplace.
        It is now the second <vendor> (after Tandem with its Non-Stop SQL) 
    	to offer an OLTP-capable distributed relational technology, and is
    	positioned to ride the booming intelligent workstation (IWS)
    	market."
                
    	"...it could enable more cost-effective use of Unix and VAX/VMS
    	environments, as well as the employment of cheap Sun workstations
    	MIPS.  While those accomplishments would be very nice, it is
    	the SQL/OLTP enablement of the IBM/Microsoft OS/2 and the IBM
    	VM/CMS platform that would provide excitement."
    
    	"While the VM/CMS strategy is not yet clear, it is most likely
    	that by year-end 1988, it is possible that Sybase would enable 
    	use of a (VAX) Dataserver as a front-end (i.e., Data Toolset
    	environment) to a VM/CMS processor."
               
        "Sybase's Key Deliverables:  
    		High-volume performance, 
    		DBMS-enforced integrity
    		High availability
    		Distributed Data Management"
    
    	"...strategy for solving resource contention between the 
    	operating systems and the DBMSs is to dedicate the environment
    	to one task, thereby relegating the operating system to network
    	manager status.  Sybase's solution for integrity control
    	("triggers" via "Transact SQL") is slick but can be imitated."
    
    	"...already achieved 35 installations before formal product
    	introduction, ..."
    
    	"We estimate that Sybase will achieve calendar year revenues
    	of $6 million from 70 sites, largely because of added emphasis
    	on end-user sales and sharp market focus -- on customers of
    	Oracle, RTI and Britton-Lee."
    
    	
    	------------------------------------------------------------
    
    	This quoting is to serve only one purpose -- this statement
    of Sybase by the leading (IBM) software market researcher goes out 
    to over 700 interfaces in the F500.  
    
    In contrast, Digital only gets indirect coverage in this area (as
    in C-ORC-323  Oracle Systems: Challenged By IBM and DEC 2/24/87)
    
    Bottom Line:  Digital has to demonstrate its ability to have a 
    clear, focused strategy for distributed databases and OLTP.
    
    Until then, Digital must build on its ability to support large 
    commercial accounts on an enterprize-wide scale.  This is a clear
    advantage over the limited support by companies like Sybase, Oracle,
    etc.

11.4Sybase info from SybaseNOVA::MAHLERAndy MahlerThu Aug 27 1987 19:5545
After speaking to representitive from Sybase, I got some performance numbers 
from them.  Here's what I got, it's not much and it's not qualified (ie, I 
doubt they had any response time constraints)

This was run against ORACLE on a MicroVAX II with 16 mb. There were two sets 
of measurements run, the first was a transaction and the second was a full 
blown benchmark.

1. The transaction is FETCH PRIMARY KEY WITHIN (1 million record relation).

			Sybase		Oracle
		       --------        --------
	  1 user:       6.0 TPS         3.5 TPS 
        10 users:       7.0 TPS         4.0 TPS

2. The benchmark run is the TP1 benchmark which is similair to Debit/Credit.

			Sybase		Oracle
		       --------        --------
	  1 user:       3.0 TPS         1.+ TPS 
        10 users:       3.0 TPS         0.5 TPS


Some other interesting information about Sybase is that it is server-based, 
so it would be comparable to Rdb/VMS and ACMS packaged together.

In a cluster, Sybase does not use the distributed lock manager, it uses a 
Master-Slave relationship to perform in a VAXcluster.  Therefore it has no 
automatic recovery system if the master node goes down.

The only other info that I have is that some of the nice features that 
Sybase has is:

	- full referential integrity, including cascading deletes
	- distributed support, including 2-phase commit and stored 
		procedures
	- triggers

Also the Sybase rep gave me a list of articles that have recently
mentioned Sybase, they are:

MIS WEEK, 5/11/87 - Sybase Makes OLTP Thrust with DBMS

A very talented colleague of mine just became one of their first seven
employees in the U.K. so they're branching out.

They'll start selling in U.K early next year once their
familiarisation/training is done.

I'll keep in touch with him and see if he'll sling any tit-bits of info. this
way.
11.6Sybase strikes Again!VAOU02::NJOHNSONNeil M. JohnsonWed Mar 09 1988 05:4029
    I would like someone to scotch a rumor that I have heard from a
    customer.  We are currently competing with Sybase at a software
    house and have mentioned to them that their SCMP agreement may be
    at risk if they go Sybase.  They replied that Sybase is going to
    become a CMP of Digital's and they have already talked to someone
    inside Digital to get this info.  This is a bit alarming.  What
    happened to our promotion of our own products?  Who out there is
    shooting us in the foot?
    
    In passing, benchmark literature by Sybase 'leaked' to our client
    show them doing roughly 27 TPS on an 8700 in a Debit/Credit style
    benchmark.  From appearances no terminal I/O was done.  Also, Sybase
    needs to pre-allocate and lock all of its buffers in memory when
    running.  This means that the full 8 to 16 MB that are recommended
    are locked in memory.  We have been trying to find out whether the
    standby server (hot backup) also needs to pre-allocate its memory.
    
    A customer benchmark purports to show Sybase as being 50 times faster
    than Rdb.  Customer achieved one transaction per seven seconds with
    Rdb and 6 to 8 transactions per second with Sybase.  We are trying
    to find out the rest of the conditions around this benchmark.
    
    Our customer keeps coming back to performance.  All of our other
    remarks about development tools, 4Gl's etc. seem to be falling on
    deaf ears.  Anyone who has any other good knockoffs please reply
    here!  We are going to lose this one and Sybase will get a foothold
    in Vancouver (Canada).

I know SYBASE is quick, but I don't believe the 1:50. Did you have a look
at their benchmark. Is RDB using the optimal strategy ? RDB can do A LOT in
7 secs. Are you talking CPU-timings or wall clock ?

Could the proverbial 'next major release' help ?
Product manager for RDB is NOVA::HORN

Try to investigate and not just take what the customer says,

Gerold
11.8What about $$$$AUNTB::BOOTHA career of MISunderstandingWed Mar 09 1988 18:4917
    Is your customer prepared to pay the price for Sybase? As I understand
    it, Sybase requires a dedicated VAX to be the database engine (Server).
    So Sybase will really cost $40-$150,000 for the software plus the
    hardware cost of the VAX itself.
    
    Question 2 is, do they need 27 TPS, or are they just entranced with
    the numbers? 27 TPS sounds great. But if they only need 10, it's
    a lot of extra expense for nothing.
    
    From what I have heard, the Sybase tools are not very good. What
    you are saying is that the customer doesn't care about expense or
    ease of use---only performance. If that is his mindset, there is
    little that will sway him from Sybase. If this customer has chosen
    to go with a product for non-business reasons, you will have a very
    hard time.
    
    ---- Michael Booth
11.9Check Those Numbers AgainAUNTB::BOOTHA career of MISunderstandingFri Mar 11 1988 18:0912
    Wait a minute! In note 11.4 Sybase quotes a TP1 benchmark of 3 TPS
    on a Microvax. Now they are telling this customer that Sybase will
    do 27 TP1 TPS on an 8700. Some interpolation will give you a growth
    in power that is not just linear, but linear + 50%! That is amazing
    performance. One would guess they are now quoting numbers that involve
    heavy amounts of read-only transactions.
    
    If the first set of numbers is correct, Sybase will do around 16-18
    TPS (TP1) on an 8700. That hardly puts it in the ultr-high performance
    class.

11.11SYBASE database server vs ACMS (my 2�)BISTRO::GODFRINDI want SETPRV for ChristmasWed Sep 13 1989 18:0114
Something has been nagging in the back of my mind for sometime now.

One point where we criticize Sybase on VMS is that it runs in one single
database server process, whereas we run Rdb/VMS in each user process (so
avoiding the need for a centralized server).

BUT, whenever we want to be serious about high performance OLTP applications,
we talk ACMS, which precisely implements a server-based solution. And it is not
even multi-threaded (as the Sybase server is) ;-) - of course, we can have
multiple ACMS servers - (does Sybase ?)

Any comments ?

11.121 process is very special caseCOOKIE::BERENSONI&#039;m the NRAWed Sep 13 1989 20:4215
The problem with SYBASE is that they run in a SINGLE process.  They do
this so they can perform all of the inter-transaction, inter-user
coordination themselves, rather than using operating system facilities.
It is also highly portable, since it is fairly independent of o/s
facilities or even memory management models (which would impact a
multi-server approach).  But basically, for any one database you have
only one server, and this just doesn't work well for SMP.

The approach we recommend for ACMS/Rdb does reduce the number of
processes, but we suggest tuning so that you never get above a
fractional queue of tasks waiting for a server to become available.
Thus, you just about always end up with AT LEAST as many servers as
there are processors in your SMP system (and usually more).

11.13Does it run on clusters yet ?YUPPY::FINNFri Nov 24 1989 17:5311
    I have been asked to configure a LAVC for a Japanese bank to run
    Sybase. They currently have a MicroVAX 3400 with 7 VAXstation 3100s
    as the front-end. They are currently intending to add another couple
    of VAXstations and a second 3400.
    
    I understand that Sybase cannot gain any performance from clusters
    and that you cannot have a server on more than one cluster node
    accessing the same database. I am trying to get some information
    from Sybase, but this is not very easy, so does anybody know the
    current position and whether they have any plans to support clusters
    in the future ?
11.14UnlikelyCLYPPR::BOOTHWhat am I?...An Oracle?Fri Nov 24 1989 17:5712
    Be very careful. Sybase on VMS itself doesn't perform well. The Sybase
    architecture is geared to stand-alone uniprocessors. They are in the
    process of writing some kind of "fix" that will allow them to use SMP.
    It has been reported that this will require 200,000 lines of new code.
    That doesn't sound very pretty.
    
    VAXcluster architecture is diametrically opposed to Sybase architecture
    (single server). A Sybase move to effectively support clusters would
    amaze me given the architectural problems of single server in a
    VAXcluster.

11.16APT Workbench and DECwindows ?TRHVS1::PAULPaul Helseth @TDO, EIS NorwayThu Dec 14 1989 09:1312
    Does APT Workbench support DECwindows on VMS ?
    
    A potential customer has decided on Sybase and X-windows, but he is
    worried that APT Workbench (the "4GL" in the Sybase tool-set) maybee
    cannot run on DECwindows, and that the applications generated by APT
    Workbench will be only charater-cell-applications (VT-emulation) and
    not DECwindows-applications (with menues etc...).

    Sybase to produce relational database aimed at VAX9000
    
    Sybase is to launch the first relational database for symmetric
    multi-processing machines, including the VAX9000, later this year.
    SQL Server with the new Virtual Server Architecture will be available
    on DEC, Stratus and Pyramid machines in the autumn.
    Like the uniprocessor architecture, VSA provides a database operating
    system with multitasking kernel that accepts user requests and manages
    database tasks. Marketing director John Stevens said this is unlike
    most RDBMSs because it uses the main operating system only for low
    level tasks. VSA creates a database process on each CPU, although these
    appear as a single process, or virtual server, to clients on the
    system. VSA distributes user requests between CPUs and manages load
    balancing and synchronisation independantly of the operating system.
    On a Stratus XA2000 Model 160, SQL Server with VSA achieved a
    throughput rate of 43 tps, according to Stevens, running the TP1
    benchmark. This compares with 8.1tps on a uniprocessor server, and even
    better results would be expected on a VAX which does not have the
    additional overheads incurred by fault tolerance.
    Stevens claims VSA offers almost linear scalability - when a new CPU is
    added, database performance increase around 95 per cent. The
    near-independence from the operating system also means SQL Server
    requires only 50Kbytes of memory per user.

    "DEC last week announced it will resell to the U.S. Military Sybase's

11.22Cashing in on Desert ShieldMAIL::DONCASTERThu Sep 13 1990 00:4749
    From a full page ad in Comuterworld, September 10, 1990 (copied without
    permission):
    
    [large bold letters]
    The Military Airlieft Command Has Good Reasons For Choosing Our On-Line
    RDBMS.
    
    [a large picture of Saddam is included with the ad]
    
    [text]
    One reason is as close as today's headlines.
    
    The crisis in the Middle East unleashed the largest airlift in the
    history of the Military Airlift Command -- more than 1,100 aircraft,
    flying 100,000 troops and a billion pounds of cargo to Saudi Arabia,
    all on a moment's notice.
    
    MAC chose SYBASE for exactly that kind of operation.
    
    Because only SYBASE, with its Client/Server Architecture, can provide
    the distributed computing capabilities needed to manage a massive
    operation absolutely dependent on real-time access to on-line
    information.
    
    SYBASE lets MAC use familiar client hardware, like PCs and Macintoshes,
    to access critical data from any of its 211 locations worldwide.
    
    SYBASE supports absolute data integrity and security in MAC's worldwide
    distributed environment.  Business rules are written once -- into the
    SYBASE programmable server -- and automatically implemented across all
    applications and enforced throughtout the network.  And only SYBASE
    Secure SQL Server offers multi-level data security designed to meet B1
    level standards.
    
    SYBASE delivers the high application availability MAC requires. 
    Back-ups, recoveries, diagnostics, transaction logic and integrity
    changes all take place while applications run.
    
    In short, only SYBASE offers everything the Military Airlift Command
    needs to manage a massive, worldwide, on-line enterprise.  One which,
    if it were an industrial company, would rank number 10 on the Fortune
    100.
    
    It's easy to find out more about how Sybase can help you handle your
    information management needs -- crises and all.  Just attend a free
    Sybase seminar.

11.23The facts regarding Sybase & Desert ShieldMAIL::DONCASTERThu Sep 13 1990 01:2657
    RE: .22
    
    Now for the facts...
    
    The Military Airlift Command (MAC) has several Command and Control
    systems which are used in carrying out the mission of MAC.  One of the
    primary systems in use by MAC is the Global Decision Support System
    (GDSS).  (For additional information on GDSS, please see this week's
    issue of Digital Today, or Computerworld, Sep 3, p 6.)
    
    GDSS is based upon Rdb/VMS.  No MAC system currently deployed uses
    Sybase.  Additionally, all of the client hardware mentioned in the
    previous note is not deployed.  GDSS is based upon VAX computers, using
    VMS, Rdb/VMS, DECnet and other Digital products.  The user devices are
    VT terminals and VAXstation workstations.
    
    During the current Desert Shield operations, GDSS has performed in an
    outstanding manner.  While other Command and Control systems were
    choking under the heavy workloads, GDSS continued to perform.  Within
    days of Desert Shield beginning, GDSS had to perform additional work to
    replace some systems which were not functioning.  Systems which should
    have fed information to GDSS, could not do this.  GDSS had to pick up
    the slack, and actually feed results back to systems so other DoD users
    would stay informed.  Additionally, under heavy load, MAC added many
    other users and several additional sites.  I should point out that it
    is rare for any application to actually grow in deployment and function
    under heavy stress conditions.  
    
    Back to Sybase...
    Sybase is currently installed in MAC's Multilevel Secure (MLS) testbed
    which happends to be at Digital's St Louis facility.  Digital is the
    Systems Integrator of the MLS/GDSS Program, a program designed to add
    MLS capabilities to the existing GDSS.  Sybase is not supporting Desert
    Shield, nor is any Sybase product likely to support Desert Shield
    (unless this operation lasts more than a few years).
    
    Sybase has not been selected for MAC's future systems.  Sybase has
    merely been selected for inclusion in the testbed.  This makes Sybase a
    candidate for use in the future.
    
    Based upon what we've seen of the Sybase product, I can't recommend
    it's use.  The product is bug ridden, slow and unreliable.  Any
    database which returns different results for the same query is not one
    I'd like to use for a mission critical application.  Additionally,
    Sybase's tech support people have generally not even heard of the
    Secure SQL server, and when they have, they don't really understand it.  
    
    Regardless, I just wanted to let you all know that the ad in .22 is not
    true.  We have alerted our customer, GSG legal, Corp PR, and the
    marketing folks which oversee our agreements with Sybase for the Secure
    SQL Server.
