Hello all
I have problem with oracle 11 in Suse. We try upgrade Suse from 11.1 to Suse 11.2. Our scenario is:
We install new system (SLES for SAP Applications 11.2 (x86_64)) and copy all file from old SAP system on Sles system (10). All OS setting is copy from 11.1 to 11.2. We use this scenario in all other systems, and work property (on ERP, EP, XI dev & test), but not in this system (prodution XI on NW 7.0).
So, after copy all file from orginal system to new one we start oracle, but oracle not working properly, after some time, its crash. I found that the problem is when system try switch logfile (in original system its working correct). See steps to reproduce crash:
SQL> startup
ORACLE instance started.
Total System Global Area 2472083456 bytes
Fixed Size 2230792 bytes
Variable Size 872416760 bytes
Database Buffers 1577058304 bytes
Redo Buffers 20377600 bytes
Database mounted.
Database opened.
SQL> alter system switch logfile;
System altered.
SQL> alter system switch logfile;
System altered.
SQL> alter system switch logfile;
System altered.
SQL> alter system switch logfile;
and now oracle do nothing, system can't finish this step. When I shutdown oracle in abort mode (in other system can't stop), on OS level I have still working proces ora_lgwr, which I can't kill, because this process wait for I/O (I think for disk write).
I have snapshot for this installation, and I tried to do different trials (change OS limits, change size/number of redo log, change redolog destination, change block size in dysk) and always system crash.
On alert log, I can not find anything interesting, on OS level the same.
Anybody can help me ?
Best regards
