Trouble shooting with Grid Control Management Agent installation / Registration

When you got below error message at last screen while installing Grid Control Management Agent S/w

The "/oracle/agent10g/cfgtoollogs/configToolFailedCommands" script contains all commands that failed, were skipped or were cancelled. This file may be used to run these configuration assistants outside of OUI. Note that you may have to update this script with passwords (if any) before executing the same.

One of reasons would be incorrect password

Check the Installation log file:
