I installed a sap solution manager application in suse os last week, during the sap software package installation periods, it asked to install the oracle database.
I checked the suse and found the sap had produced the oracle installation progeress in "/oracle/stage/112_64/database/SAP", I followed the installation guide and finished the instalation of oracle.
But a DB connection problem occured between the sap and oracle.
I have check the sys dba and sap user can login normally. The listener status are normal. Sys dba operations are normal.
Then I found a error in sqlnet.log. Who can help me and tell me what's wrong?
