I am trying to install the Apr 2013 PSU using opatch auto, and I get this error while patching the grid home, oracle 11.2.0.3 on linux x86-64. The error below is in the log file: 2013-05-29 18:42:14: /bin/su exited with rc=1 2013-05-29 18:42:14: Error encountered in the command /u01/app/ 11.2.0.3/grid/bin/qosctl -autogenerate > Syntax Error: Invalid usage > > Usage: qosctl <username> <command> > > General > username - JAZN authenticated user.

The error 'Failed to patch QoS users' is the only message opatch returns to the screen. I found a note about QoS in the patch installation instructions, but it didnt seem to be relevant to this message. Has anyone else hit this? Any ideas? -- Andrew W.
