Hi Sidharth,

Since you are able to login to ABAP, the DB must be up, but to double check run "r3trans -d" at command prompt and verify the connectivity.

Secondly, you need to check whether java server processes are running... using JCMON.

If they are running, then try a stop SAP, reboot and start SAP; so that dangling shared memory will be free for use after reboot.

If not, then you may check why the java instace in failing to start, monitor jcontrol and jlaunch when the instance is starting and defaulttrace#.trc logs to know why the instance failed to start.

Otherwise there is no specific relation between offline backup and SAP applications.

Hi,

the error means

One of the reasons is that there was not enough memory available to create a shared memory segment.

On Unix this might be indicating that some kernel parameters are set too low (SHMMAX, SEMMNI, ...).

A previous shared segment that was not cleaned up correctly might also exist.

Check with you Unix engineer for possible causes/fixes.

Please stop icomplete sap and restart sever.

Thanks & Regards,

Try TCode - SLDCHECK and post the results. Make sure the SLD is running..

Also is this a recent installation? or have to done any upgrade by patching SPs in ABAP and Java?

If yes, Have you performed all post-inst steps?

ABAP n Java Stack Level?

Thanks

Hi,

Please check you database is running.

Just restart ur oracle service or ur server where oracle installed

Other reason may be probably means that the service is started, but not yet the instance. Use oradim to start the instance.
