Hi Reza,
OPS$SAPSERVICERST & OPS$SAPSERVICEVIP
Do you have any other system with RST and VIP.
Please provide the output of this two sql statement :
1. SELECT OWNER FROM DBA_TABLES WHERE TABLE_NAME = 'SAPUSER';
Then run
2. SELECT * FROM "OWNER".SAPUSER; (OWNER will be name which you get in the first sql command)
With Regards
