1079.0. "Create table just hangs." by chsr38.ch.oracle.com::ROHR (Oracle Rdb support Switzerland) Thu Jul 11 1996 09:25

(no doc) * (no shoulder to cry on) = clueless = bear with me

Customer is trying to create a table and it just hangs. All the other create
table problems in notes had at least a nice neat bug check or an error message...

create link oracle to 'grdba2::bere$test';   ...fine
create table oracle link to bere$test using oracle;  ... hang

What I have checked so far:

Rdmmon.log shows a normal user attach

rmu/sho stat shows no locks at all

the netserver.log of all involved accounts (rdbserver, dd_mgr etc.) show
nothing but normal attaches.

The process is in LEF and not moving (on the Rdb node)

rmu/sho lock/wait bere$test with the PID show nothing

rmu/sho lock/blocking bere$test with the PID gives about 25

There is only one user in this database and that's me via DBI

The DDAL log files on the DBI node are empty for the time period

rmu/show priv and extract/item=prot seems ok.

and and and ...

Who gives me the next clue?  

Rdb node V6.0-03
Dbi node V6.1-02
Dbi version (how do I find out?)

Thanks Regina

1079.1They are on OSIchsr38.ch.oracle.com::ROHROracle Rdb support SwitzerlandThu Jul 11 1996 12:4615
    I have some more info: Both systems are on OSI. The last system changes
    were around mid april (VMS 6.2). After the reboot everything was
    working. After a generator check (they call it Diesel test) and the
    following reboot some 2 weeks ago, it stopped working.
    
    In that period on the DBI machine were installed Sql Services ECO2 and
    the ALP security patch, on the Rdb machine (vax) I couldn't find any
    .VMI_DATA.
    
    Also, they did some renames on proxies and node names, but the DTM part
    seems to be ok (log file names).
    
    Thanks,
    Regina
     
1079.2Could the DECdtm log file be full on the remote node?BROKE::ABUGOVThu Jul 11 1996 17:2917
    
    Hi Regina,
    
    We have seen hangs when the DECdtm log file is full.  You may want to
    look on the node where the remote database exists and do an:
    
    mcr lmcp
    
    sho log/current
    
    If you see that there is a stall in progress that would mean the decdtm
    log file needs to be emptied.
    
    If not then post a note here and we'll put the high power thinking caps
    on.

1079.3no dtm logs fullchsr38.ch.oracle.com::ROHROracle Rdb support SwitzerlandFri Jul 12 1996 09:4014
    Hello,
    
    no it is no full dtm logs problem, I have checked that. Customer can't
    transfer data since about 2 weeks, and called us after DEC said it must
    be DBI and/or Rdb. 
    
    Would a recreate of a new dtm log be worth a try? RDB$REMOTE access
    works fine, so I really suspect s.th. on the system side, but where?
    
    Should I force them to install the DTM ECO?
    
    Thanks for any hint,
    Regina
    PS: I have online access to the systems
1079.4$.02HOTRDB::PMEADPaul, [email protected], 719-577-8032Fri Jul 12 1996 11:401
    I would definitely insist that they install the latest DECdtm patches.
1079.5Another idea...BROKE::ABUGOVFri Jul 12 1996 20:0313
    
    I agree with Paul - they should install the latest ddtm patches.  The
    other thing I would suggest looking at is also DDTM related - since the
    node was renamed make sure the stuff that ddtm uses also got updated - I
    think they use either sys$node or scsnodename but you may want to check
    in the movies::decdtm notes conference to find out (I haven't used ddtm
    on an OSI system).  Also the DDTM log file would need the new node
    name.
    
    Hope this helps, let us know if there is still a problem after checking
    on those things.

1079.6Yeah, get me all those DEC notesfileschsr38.ch.oracle.com::ROHROracle Rdb support SwitzerlandThu Jul 18 1996 03:397
Unfortunately I can't look into Dec's Notes anymore. Though, as Dec still
accesses the now Oracle notes, it would be a nice idea if we could look at
Notes like DTM and VMS and while we are at it compilers and ACMS and OSI
and... 
Am I too demanding...? ;-)

1079.7Some stuff to do to help us debug the problem...PORTME::ABUGOVFri Jul 19 1996 11:5920
    
    Hi Regina,
    
    Could you define some trace flags and mail us a pointer to the trace
    file (don't post it here - it will be quite verbose).  I contacted one
    of the DDTM folks via mail and we will probably have two or three
    rounds of stuff for you to do before we actually track this down.  I'm
    not sure what else to do.  We might be able to streamline things if we
    can get dial in access to your system.
    
    For now, can you:
    
    $define dbi_trace_flags "SDI,MDM_ATT"
    $define dbi_trace_output "FILE.EXT"
    
    then send us or post a pointer to the file.ext?
    
    Thanks,

1079.8Some more things to try...BROKE::ABUGOVTue Jul 23 1996 12:3437
    
    Hi Regina,
    
    We got the trace flags results - this confirmed that indeed the hang is
    happening on a start transaction.  I'm not sure it is DDTM related
    though.
    
    Can I ask a few more questions?
    
    1) Can the remote database be accessed from the remote node without
    dbi, i.e. can a user from the node dbi is installed on attach to the
    remote database and start/commit transactions without a problem?
    
    SQL> attach 'file node::bere$test';
    etc.
    
    2) if that works, can you check node grdba2 and make sure ddtm has a
       log file and that it has the right name (i.e.
       sys$journal:system$grdba2.lm$journal i believe would be the right
       name.
    
    3) Please confirm that the dbi catalog is not also the database that
       has the table you are trying to import (the catalog cannot also be a
       database that contains other data)
    
    4) if test 1) works, 2) is OK, and 3 is OK, then can you create a file in 
       the user's default directory called rdb$client_defaults.dat?  In
       that file include the line:
    dsp_debug_flags TRUE
    
    Some extra output should now go to the user's screen.  Can that screen
    be sent to us to we can see what call dispatch was making when things
    hung?
    
    Thanks,

1079.9DECdtm is the culpritCHSR36::JSUBRIFocus on Open/Rdb++Wed Jul 24 1996 07:466
Since they have patched the DECDTM with ALPDDTM02_070 on the 
DBI machine all is ok.

Thanks to all
