Server Does not start after backup complition
We are facing following problem some times after backup completion.
Our Setup is : SAP ECC 6, Oracle 10g, HP-UX 11.31.
We are scheduling the whole database offline + archive log backup during night.
After completion of backup the SAP does not start. I have checked the following things.
1. Database is started : OK.
2. SAP related services at O/S level : OK
3. Listener is OK
4. No startup log generated related to SAP
But I am not able to connect to SAP thru SAP GUI.
If I tried to start SAP using startsap it will not respond for long time. Even I have tried to startsap after shutting down database, kill all SAP related services at O/S level. But startsap doesn't respond.
When I restart the server, after that I am able to start SAP.
Is there any memory fragmentation related problem ?
Before some time same thing is happened with our production server, but at that time I have deleted Archivelog files manually before tacking backup. In this case if I take backup "whole database offline + archive log " then server doesn't start. At that time also I have to restart the server. So the Problem is identified.
But in this case i.e on our Quality Server not able to trace out problem.
Thanks in Advance,
