Hello

Please check two below topics.

1º Be sure that same datalist\barlist i snot running two times in parallel.

https://softwaresupport.softwaregrp.com/group/softwaresupport/search-result/-/facetsearch/document/LID/QCCR2A73153

2º  If you are using omnirc variables OB2PORTRANGE or OB2PORTRANGESPEC please remove it are not needed anymore with DP 9.09 because allocate TCP ports in a  different way.

Best Regards

Session ended because no one connected to it within time period defined by SmFirstConn (=60 seconds).

Try uncommenting and increasing SmFirstConn in global options (/etc/opt/omni/server/options/global) to a higher value.

This error message usually shows up if the Cell Manager is in Maintenance Mode. Check omnisv -status for details. You can stop it using omnisv -maintenance -stop.

Re: Backup not executed as per schedule in DP 9.09

Hi DP_User,

This is strange, but then I would like to know which sessions are not executed and if you can check the following logs in OmniBack\log\server for related entries: crsevents.log, sm.log, omnisv.log, Ob2EventLog.dat and Ob2EventLog.txt as well as maintenance.log and debug.log in OmniBack\log.

Sebastian Koehler

Re: Backup not executed as per schedule in DP 9.09

the issue occurs at random time, the backups are skipped for any perticular time it can be for a window 15 min to 1 hrs.

Any FS/Oracle DB/IDB backup all missed at that time when we have the issue.

checking even logs i find [138:726] CsaStartSession failed for datalist "Backup_spec" error. there is no error in Debug related to this issue.

Re: Backup not executed as per schedule in DP 9.09

Hello DP_User,

You're having this kind of error since a long time now? Can you please share /etc/xinetd.d/omni from your Linux Cell Manager and check /var/log/messages for any xinetd related errors when backups are skipped?

Maybe INET is not accepting the requests from BSM due to resource limits.

Regards,
Sebastian Koehler
