Has anyone gotten this error?
Error: Please read the information below.
Group 'mqbrkrs' does not exist. Create the 'mqbrkrs' group before relaunching
this wizard.
If you ignore it and move forward, it complains about the mqm id.
We verified that both the mqbrkrs group exists as well as the mqm id so this doesn't make sense.

It's a long shot, but what are the permissions on /etc/group and /etc/passwd ? Also, how did you verify that the group and user exist? |

The admin is checking on the permissions. But we verified that the group/id existed both thru smit and through the /etc/group file. We also tried deleting and recreating it.

The reason I ask: I once helped a customer with a Solaris system which had 0400 -r-------- for /etc/group. The admin was asking me why the MQ authorization code was failing. That file had to be world readable in order to allow the group-querying C library calls to work. AIX may be different though (don't know...) |

What the installer is doing is to first create a temporary file in /tmp and then try to chgrp it to mqbrkrs and then create another temporary file and chown it to mqm. If these fail then the error is produced

For example, if the user doing the work is not root. Only root can do chmod, chown and chgrp. |

Yes, but that should be caught earlier, the installer checks that it is being run by root.

OK so is the user perhaps running locally as root, using an NFS file system that is set up (exported by the remote system and/or mounted by the local system) in such a way that it doesn't respect the authority of user 0 ? |

Perhasp the user should try to manually create a file in /tmp and do the chgrp / chown from root and see if that works.

The group was initially created as mqmbrks. We did notice and fix this before beginning the installation but for some reason, the OS was not recognizing this. We decided to do a reboot of AIX and that seemed to fix our problem...go figure - I wouldn't have expected this on AIX!

Looks like the uname was set up incorrectly on the box and after modifying it, the box should have been rebooted.
