What are these enablemgr and enableiod scripts all about?
They are simple scripts that can be used to set up the links in the rc.d directories on RedHat machines in order to start the iod or manager at boot time. For example, if you wanted to have the manager started on a machine on boot, you should run the enablemgr script once on that machine. These scripts (if used) only need to be run once for each machine. The daemons will start on boot from then on.
