Hi folks,
My server was rebooted and now the sap system won't start.
Windows 2003, SQL Server 2005. Has been working fine for a long time.
I've tried restarting everything and changing memory parameters - seams like there is same available memory and pagefile as before. No other errors in the event logs worth noting.
I get these errors in the WP traces...
B dbtbxbuf: Buffer TABL (addr: 00000000230E0160, size: 30000000, end: 0000000024D7C4E0)

I would appreciate assistance is troubleshooting this further.

The instance is now able to be started.
The parameter rsdb/obj/max_objects is now adjusted from 20000 (was adjusted by Sap upgrade tool during 701 ugprade) to 2000 (SAP default) and the work processes are then able to obtain the required shared memory.

Seems the SAP system is unable to allocate/create shared memory that is needed.
Can you do a "cleanipc remove <instance #>" and then try starting the SAP system again.

Thanks Dibya,
I understand that the cleanipc command for cleaning up shared memory applies to unix only.
We are on Windows as I've mentioned.
I've read that there may be something using the saposcol -d but I've rebooted the server a few times so this should clean up any shared memory on windows.
Kind regards,
Dave
