Dears,

We have Upgraded Oracle 9.2.0.6 to Oracle 10.2 on Windows.

As per Upgrade document we have completed all steps but now my SAP system is not getting up and Work processes are ending with error:

• ERROR => OCI-call 'OCIServerAttach' failed: rc = 12537

[dboci.c 4289]

Hi,

You can get the ORA-12537 error if you listed 10g database SID with 9i listener.

The ORA-12537 error sometimes relates configuration issues in the sqlnet.ora, tnsnames.ora and listener.ora files. Verify that you service names match between your listener and remote client connect strings.

Please check SAP note 1185271 - Error: "ORA-12537: TNS: connection closed:- 12537" when attempting to refresh a report based on an Oracle universe

Try starting SAP again., if it fails then please provide contents of startdb.log

Try this command

R3trans -d & provide resulting trans.log

Hope this helps.

Thanks,

Hello Susil ,

SAP note 1185271 - Error: "ORA-12537: TNS: connection closed:- 12537" is NOT visible / Publish for customer. Then what exactly you have seen in the SAP Note.

Thanks
