Hi,
Can you please post the ORAGETNLS.SQL
Replace the line 'Connect / as sysdba' with
'connect /@<DBSID>' (for example, 'connect /@PRD').
For <DBSID> enter the value of the environment variable dbs_ora_tnsname
556232 - Environment settings for R/3/Oracle on Windows
If errors occur even after making the changes, check the OPS$ configuration as described in Note 50088
Thanks
Rishi Abrol
