[coccus85]

I am unable to start the cognos service after configured. No errors while testing the authentication and cognos store but fail to start the service. Here’s the error occured:

To see which JVM options are based on this setting, view c8_location/bin/bootstrap_.xml and see your JVM documentation for an explanation of those options.

check the folowing:

• Is the Cognos Service in Windows disabled?
• Is the services started with sufficient permissions? re-enter the credentials for the Cognos 8 service in Windows Services.

Steps:
Go to the START menu, click “Run…”, type in “SERVICES.MSC” and click OK.
Windows Services should appear. Double-click the Cognos 8 service and click the “Log On” tab.
Re-enter the account name and password to be used by the Cognos 8 Service and click OK.

start again
