Migrating a Java client

 

If you have a Java™ client already installed (either the Java SupportPac™ MA88, or WebSphere MQ Java V5.3), and want to install the WebSphere MQ Java V6.0 product on iSeries™, first uninstall the previous client.

If you do not uninstall, and try to install WebSphere MQ Java V6.0 anyway, the installation fails with a warning requesting you to uninstall the old client.

To uninstall a previous Java client:

  1. Delete the QMQMJAVA library and the /QIBM/ProdData/mqm/java directory, by issuing the command:

    For SupportPac MA88: 

    DLTLICPGM LICPGM(5648C60) OPTION(*ALL) OUTPUT(*PRINT)

    For WebSphere MQ Java V5.3: 

    DLTLICPGM LICPGM(5639C34) OPTION(*ALL) OUTPUT(*PRINT)

  2. If the step above failed to delete the IFS directory /QIBM/ProdData/mqm/java and its subdirectories, use the EDTF command, for example: 

    EDTF STMF('/QIBM/ProdData/mqm')

    and select option 9 against the java directory.
