What were you doing?

Probably trying to start CMOD for the first time after a fresh install, or an upgrade.

Troubleshooting

In some systems, the owner of all of the Content Manager OnDemand files installed under /usr/lpp/ars/bin, /opt/ondemand/bin, or /opt/IBM/ondemand/V9.x has been changed to be 'non-root'. This is typically done for security reasons, so that a remote exploit of the OnDemand daemon (arssockd) doesn't immediately provide root privileges to the attacker. After an upgrade, these permissions may have been re-written, and need to be reimplemented.

In this case, the UNIX file and group ownership need to be set to match the UNIX user name that will run arssockd.

When performing a new installation, ensure that the following parameters all match the user name that the CMOD database runs under. Ensure that these parameters have matching case! If one is set to 'ARCHIVE', and the other is set to 'archive', arssockd will throw the ARS0152E error. In some UNIX operating systems, the case of these values must match the case of User ID defined in the operating system in order to work!!!

In ars.ini:

SRVR_INSTANCE_OWNER=ARCHIVE

In ars.cfg:

DB2INSTANCE=ARCHIVE
