Verify product prerequisites

WebSphere Application Server may not run properly if all of the required software prerequisites are not installed. If the server does not start, run the prerequisite validator. It verifies your installation, ensures that you have the appropriate prerequisite software and PTFs installed, and verifies configuration settings required by WebSphere Application Server.

To run the prerequisite validator, run the checkprereqs script from the Qshell command line.

1. On the OS/400 command line, enter the STRQSH (Start Qshell) command.
2. On the Qshell command line, use the cd command to change to the directory that contains the script:

   cd /QIBM/ProdData/WebAS5/edition/bin

   where edition is Base for WebSphere Application Server and ND for WebSphere Application Server Network Deployment.

3. Run the checkprereqs script:

   checkprereqs

   Note: The prerequisite validator can also be run as a parameter of the servicetools script. For more information and options for this script, see The checkprereqs script in the Administration topic.
