Troubleshooting the Primary Node Installation

Issue	Fix
The installer fails due to the time taken by the node manager process to start.	Check the machine network configuration to make sure that other processes are listening on same port, and that the user running the installer has the required file system permissions.
The AdminServer fails to start because the node manager process is not available.	Verify if the node manager process is still running.
A wrong database configuration is provided.	Modify the database configuration from the Oracle WebLogic Server Admin console.
