Verify product prerequisites

WebSphere Application Server - Express 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 - Express.

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

1. On the CL 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/WebASE/ASE5/bin

3. Run the checkprereqs script:

   checkprereqs

   For more information and options for this script, see The checkprereqs script.

Note: The prerequisite validator can also be run as a parameter of the servicetools script. For more information see The prerequisite validator tool.
