Oracle 11g Release 2 Oracle Linux Enterprise 5.10

[oracle@dub-ImrORA3 scripts]$ id oracle
uid=502(oracle) gid=502(oinstall) groups=502(oinstall),503(dba),504(oper)           context=user_u:system_r:unconfined_t

We recently changed the oracle id to 502 and the group oinstall to 502.

Everything under the $ORACLE_HOME/bin is owned by oracle:oinstall

Since this change we can only connect locally to the database using IPC. When we try to connect remotely using TCP we the error => ORA-12537: TNS:connection closed

When the oracle user tries to stop the LISTENER we get the TNS-01190 error.

[oracle@dub-ImrORA3 bin]$ ls -al lsnrctl
-rwxr-x--x 1 oracle oinstall 153535 Nov 26 09:45 lsnrctl

Is this an ownership/permission issue? How to resolve?

  • Did you stop the listener and database processes before changing the file ownership and uid/gid of the user/group? Have a look with ps. If not, that'll be the problem - the running processes would be horribly confused. – Philᵀᴹ Feb 4 '15 at 20:04
  • Yes, we stopped the listener and database before change ownership. And we were able to bring the database back up. – Stringer Feb 4 '15 at 20:06

    I did a blanket chown -R, which I think is the problem. – Stringer Feb 4 '15 at 20:18

    Almost certainly. Your best bet is to get a file listing from a similar server and write a small script to set the correct permissions, or do a reinstall. Not much more we can do to help. In the first instance I'd probably stop the DB, kill the listener, then do a blanket cd $ORACLE_HOME; chown -R oracle:dba bin lib lib32 network - anyway, you've messed it up by taking shortcuts – Philᵀᴹ Feb 4 '15 at 20:22

    Got it fixed. Changed owner of oradism to root:oinstall and rebooted server. DB started, but not listener. Got different error message: ERROR: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=IMR1))). Changed IMR1 to IMR0 then listener started successfully. Wish I understood this issue better. But thanks for your help. – Stringer Feb 4 '15 at 20:42
