Troubleshooting: Instance creation fails during database configuration

A WebSphere Commerce instance creation fails while you configure a remote database. This error condition might occur after the installation of a WebSphere Commerce fix pack.


When you attempt to create an instance after a fix pack installation, instance creation fails during remote database configuration. An error similar to the following message is logged in the createInstanceANT.err.log file:
execTask returned: 8


Add the non-root_user to the db2_instance_group on your remote database machine. Try to create the instance again after the user was added.
Note: You can also encounter errors when you are running a process or utility if the input parameters that are used to establish a database connection are incorrect. To validate that a database connection can be established with the configured input parameters, use the database connection validation utility. For more information about running this utility, see Running the database connection validation utility.
