Upgrading software prerequisites

The Launchpad installation interface will automatically upgrade some software prerequisites. However, if you have a version of the prerequisite that is prior to one supported for upgrade by the current version of WebSphere Business Integration Server Express or Express Plus, you will have to manually upgrade the prerequisite before upgrading WebSphere Business Integration Server Express or Express Plus. (Refer to http://www.ibm.com/software/integration/wbiserverexpress/ for information about the supported versions of prerequisite software.) You can also choose to manually upgrade the prerequisite for any other reason. If you manually upgrade a prerequisite to a version that is supported by the current release (WebSphere Business Integration Server Express 4.4), the Launchpad will detect that you have a current version of that prerequisite when you perform the rest of the upgrade. Follow the upgrade instructions provided with a particular prerequisite if you manually upgrade it.

The following sections describe steps that must be done for any database and the upgrade scenarios for several software prerequisites. Make sure to follow the steps in Backing up the system before uninstalling or upgrading any software.

IBM DB2 Universal Database

WebSphere Business Integration Server Express and Express Plus 4.4 for OS/400 and i5/OS are certified for use with IBM DB2 Universal Database (UDB) for iSeries that is provided with your OS/400 v5R2 or i5/OS v5R3 operating system.

IBM WebSphere Application Server

WebSphere Business Integration Server Express or Express Plus version 4.4 supports WebSphere Application Server Express versions 6.0 and 5.1.1, and WebSphere Application Server versions 6.0 and 5.1.1. WebSphere Application Server Express version 6.0 is the version that the Launchpad installs.

Note:
WebSphere Business Integration Server Express version 4.3.1 and WebSphere Business Integration Server Express version 4.4 web-based tools can coexist on OS/400 and i5/OS.

IBM WebSphere MQ Server and Client

If you have an older version of IBM WebSphere MQ installed on the OS/400 or i5/OS system that was supported by a previous version of WebSphere Business Integration Express, you will have to upgrade it manually to the supported version (MQ 5.3.0.2 CSD09). If an unsupported version of MQ is already installed but is not being used by any application, you can uninstall it and the Launchpad will install the supported version.

If Toolset Express is being installed, the Launchpad will detect whether or not you have a supported version of IBM WebSphere MQ installed on the Windows system and if one is not detected, it will automatically install IBM WebSphere MQ 5.3.0.2 CSD07.

IBM Java Development Kit

IBM Java Development Kit (JDK) 1.4.2 must be installed on the OS/400 or i5/OS system and on the Windows system. For the OS/400 or i5/OS system, you should have Licensed Program 5722JV1 with Option 6 - Java Development Kit 1.4 and the latest PTF group for Java installed. Refer to the i5/OS support web site for more information. On the Windows system, the Launchpad installs the appropriate JDK version (required for Toolset Express). It is not necessary to remove the previous version. However, on the OS/400 or i5/OS system, the Launchpad will not install the correct JDK. You must install it manually.
