URGENT !!! Sybase ASE 16 hanging at start

[symon_braunbaer]

Dear Experts,

PLEASE try to help me. I am in a very unpleasant situation. I stopped yesterday evening
2 SAP systems, running on Sybase 16 and Linux RHEL 7.2. I used the normal stopsap command and everything went flawlessly.

Now I am trying to start them, both are hanging when attempting to start the database:

> startsap
Checking syb Database
Database is not available via R3trans
-------------------------------------------
starting database <SID> ...
Log file: /sybase/<SID>/startdb.log

The log file /sybase/<SID>/ASE-16_0/<SID>.log exists with a size of 0 bytes and when I try to cat it, it doesn't display nothing.

When I check the processes under the syb<SID> user I see only the following ones running:

startdb
RUN_<SID>_BS -> the RUN process for the backup server
backupserver (with a lot of options)

I checked that all the datafiles and the log file in sapdata_* and saplog_1 are having the timestamp of when I had stopped the system yesterday afternoon.

I am unable to open an OSS message, as my SUSER isn't authorized for doing that.

Also what I forgot to tell:

In top - startdb uses around 12% CPU and it's changing slightly between 11% and 18%.
From what I could check for example with iostat, there is almost no disk activity 😞

Hi Symon,

Are the SAP systems mentioned in this thread, still down? If yes, then can we please check the contents of /sybase/<SID>/ASE-16_0/install directory: especially <SID>.log & RUN_<SID> files.

Please let me know if you are able to do the following as syb<SID>

cd /sybase/<SID>/ASE-16_0/bin

dataserver -v

You can also trying starting the ASE via cmd: startserver -f RUN_<SID> from the install dir, if permissible.

Thanks,
