I am getting following error message
You are not autorized to perform the maintenance, only the original installing user pbalamu2 to perform maintenance activities. but we dodn't have the above user in the system
Have a look at the configuration.xml in install dir. Search for "installingUser". There you will propably find "pbalamu2". You can change it to get tem started, but there must be a reason why this user is in configuration.xml. And changing the user may cause trouble...
