TNS-12537 Via Listener on Unix: Grid and Oracle Owners are Separate

edited Oct 18, 2017 9:38AM in Database Networking (MOSC) 1 comment

A very common problem with a very simple remedy!

This problem occurs often in installations where the listener runs under the GRID owner and

services connections to a database that runs under a separate user (oracle).

See this document:

ORA-12537/ ORA-12547 or TNS-12518 if Listener (including SCAN Listener) and

Database are Owned by Different OS User (Doc ID 1069517.1)

Check this first:

$ ls -l $RDBMS_HOME/bin/oracle

ls: /home/oracle/app/oracle/product/11.2/db/bin/oracle: Permission denied    <====Here's the problem!

Note the correct permissions for the 'oracle' binary:

The oracle binary should have permission of 6751:

-rwsr-s--x 1 oracle asmadmin 184286251 Aug  9 16:25 /home/oracle/app/oracle/product/11.2/db/bin/oracle

Howdy, Stranger!
