SAP-CC/BC,
half an hour ago we had a db crash.
After checking the diag files I found some hints that
something's wrong with creating a communication semaphore.
Is this Linux?
How many semaphores do you have? On our DB-Server:
# sysctl -a | grep sem
kernel.sem = 4096 512000 16002048
Hi again,
the command tells me:
sysctl -a | grep sem
kernel.sem = 25032000 32 128
seems you have a lot more ;-)
What exactly does this mean (in combination with sapdb), and
how can I increase this value ?kernel.sem=4096 512000 1600 2048
The definition is
kernel.sem:
2003-11-12 03:21:35 1 ERR 11282 IPC create_shm: shmget error,

3)Recovery-Recovery Wizard
Here you should choose Restore instance for recovery. If the DB comes
online it will write a timestamp into the logarea and your restored DB will
not work with this logpage.
The correct way would be:
- Create Instanz (new or initialize)
- NEVER bring it to online
Upon looking in knldiag file, I see a lot of DATACACH LRU
OVERFLOW:32.
can you increase the DATA_CACHE?
If have seen this once too here on our system but it didn't impact
performance.
Check with
# x_cons SID show active 1
what the DB is doing...
The partition where the archived logs
During hang situation, when I refresh my 'Activity' window on
DBM I see value 1 for Lock Owner and 1 for Lock Requester.
can you run
x_cons show active 1
when it locks up? This will show what the tasks are doing...

The naive approach (reconfigure XServer service, start it,
see what happens) results in error 18666, user missing privilege.
I think the users need the following priviledges:
- start as a batch job
- start as service
- allow to replace token on processlevel
Then it should work...
Greetz,
I think the users need the following priviledges:
- start as a batch job
- start as service
- allow to replace token on processlevel
That doesn't work either. The same error message is logged.
I have no further idea - just thought, this should work.
Maybe someone of the SAP team

If you use IBM JDK try
$ jre -cp sapdbc.jar
Check you java version with
$ java -version
If it's lower than 1.4 you should consider upgrading, different java
versions can coexist in different directories
Just checked out java -version on the Unix host and found
that the version is 1.1.8, could that be a problem?
Yeah - I'm quite sure that this ancient version can't execute code that's
built with newer versions.
I'd at least download a recent 1.3.1 built:

Hi Tilo,
could you please check, whether SQL, TOOSMALL or NOMEDIA are
defined in your context by inserting something like:
#if defined(SQL)
#error SQL is already defined
#endif
into your DBMSrvMsg_Error.hpp, right in front of the enum ErrorID.
I did this:

These are only the USERTASKS, the DB has some more itself (Servertask,

Also, the DB is just started up and each process is 68MB in

Hey Daniel,
Our code requires a rather old version of bison. That version
should be part of both the binary tool distribution and the
source tool distribution. Try $TOOL/gnu/bin/bison --version,
this should emit GNU Bison version 1.25
Yeah.. but it seems that configure will check for

dramatically! Very impressive! Any general tips?
There is a rule of thumb
I have question,
the only way to commit the transaction log of SAPDb is
setting AutoLog ON?
With AutoLog OFF i have the problem that transaction logs
reach 100% and don't decrease..
It seams be the only way for many changes and small log area.
