Upgrade notes

WebSphere Business Integration Adapters API and run time

Make sure that you run this version of the adapter with WebSphere Business Integration Adapters run-time version 1.8.0 or later.

The WebSphere Business Integration Adapters API .jar files and the associated scripts (CWConnEnv.bat and CWODAEnv.bat for Windows(R); CWConnEnv.sh and CWODAEnv.sh for UNIX platforms) are installed by the WebSphere Business Integration Adapters API. Before installing the adapter, make sure that the WebSphere Business Integration Adapters run time is installed. If the version is not 1.8.0 or later, you must download the latest API. This section provides instructions for verifying the API version, downloading the latest version, and enabling the adapter to run on various versions of InterChange Server and Adapter Development Kit (ADK).

Verifying the run-time version

To check the version of the run time, locate the manifest file (ProductDir\lib\WBIA.jar) and open it in a suitable Java JAR editor. Look for the following lines:

Implementation-Title: "CWConnectorAPI"
Implementation-Version: 1.8.0

The line Implementation-version indicates the installed version of the API. If the version is not 1.8.0 or later, you must download the latest run time.

Downloading the run time

To download the latest version of the run time:

  1. Go to http://www.ibm.com.
  2. Click the Support & downloads tab.
  3. Under the Downloads heading, click Downloads & drivers.
  4. In the Enter search terms field, type "wbia api" and click Submit.

After you download and install the run time, you should see the following files:

lib\WBIA.jar
bin\CWConnEnv.bat (Windows)
bin/CWConnEnv.sh (UNIX)
bin\CWODAEnv.bat (Windows)
bin/CWODAEnv.sh (UNIX)
connectors\messages\CwConnectorAgentMessages.txt

Enabling adapters for earlier versions of Adapter Development Kit and InterChange Server

This adapter runs only on the current Adapter Framework version 2.6.0.

Known problems and workarounds

The following problems have been found in this release:

Tracking
number
Description
58988 The adapter hangs when deployed on a Linux(TM) multi-processor system. This problem is caused by a known Linux JDK 1.4.2 issue that causes a hang during garbage collection. (The PMR number opened for this JDK issue is 27182.001.866.)

To work around this, modify the adapter start script to set the JVMArgs variable with the option "-Xgcthreads1" as shown in the following example:
JVMArgs="-Xgcthreads1 %JVMArgs%"
34668 WebSphere MQ version 5.3 at CSD06 or lower does not support bi-di data in the JMSCorrelationID field; therefore, to fully utilize the bi-di capabilities of the adapter, you will need WebSphere MQ version 5.3 at CSD07.
