11.1 | Be honest... | BMT::NG | Thomas K. Ng (334-2406) | Tue Jun 30 1987 23:36 | 53 |
| 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...

11.2 | Specialization has its benefits | NOVA::BERENSON | Rdb/VMS - Number ONE on VAX | Wed Jul 01 1987 16:16 | 12 |
| 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.

Aye, a lively discussion...
re .1
There is three research notes from Gartner Group's Software
Management Strategies (SMS) service in the library (for location
see note of PACE, this conference).
C-SYB-370 Sybase Becomes a Relational Player June 12, 1987

Database Engine
P.S. I'll comment further after reading Sybase notes.
re .2
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.

Larry T.

11.4 | Sybase info from Sybase | NOVA::MAHLER | Andy Mahler | Thu Aug 27 1987 19:55 | 45 |
| 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:
COMPUTERWORLD, 6/8/87 - Users point to Sybase potential
MIS WEEK, 5/11/87 - Sybase Makes OLTP Thrust with DBMS
BUSINESS WEEK, 5/11/87 - The Free For All Has Begun

They'll start selling in U.K early next year once their

11.6 | Sybase strikes Again! | VAOU02::NJOHNSON | Neil M. Johnson | Wed Mar 09 1988 05:40 | 29 |
| 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

Could the proverbial 'next major release' help ?

11.8 | What about $$$$ | AUNTB::BOOTH | A career of MISunderstanding | Wed Mar 09 1988 18:49 | 17 |
| 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.

11.9 | Check Those Numbers Again | AUNTB::BOOTH | A career of MISunderstanding | Fri Mar 11 1988 18:09 | 12 |
| 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.

11.11 | SYBASE database server vs ACMS (my 2�) | BISTRO::GODFRIND | I want SETPRV for Christmas | Wed Sep 13 1989 18:01 | 14 |
| 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 ?

11.12 | 1 process is very special case | COOKIE::BERENSON | I'm the NRA | Wed Sep 13 1989 20:42 | 15 |
| 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).

11.13 | Does it run on clusters yet ? | YUPPY::FINN | | Fri Nov 24 1989 17:53 | 11 |
| 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 ?
|
11.14 | Unlikely | CLYPPR::BOOTH | What am I?...An Oracle? | Fri Nov 24 1989 17:57 | 12 |
| 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.

A potential customer has decided on Sybase and X-windows, but he is

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.

"The three-year Digital Distributed Software (DDS) agreement is a major
win for Sybase because of the boost it will get from DEC's endorsement

Further statements: about how this is further evidence Digital cannot

11.22 | Cashing in on Desert Shield | MAIL::DONCASTER | | Thu Sep 13 1990 00:47 | 49 |
| 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

11.23 | The facts regarding Sybase & Desert Shield | MAIL::DONCASTER | | Thu Sep 13 1990 01:26 | 57 |
| 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.
