This section describes how to upgrade the connector:
The ALE Module persistently stores IDoc objects and Transaction IDs (TIDs) for every transaction it receives from the SAP application. In releases of the connector prior to version 4.8.x, the connector used IBM WebSphere collaborations, business objects, and maps to store the data in the repository. Version 4.8.x of the connector replaces the previous way of TID management with the use of MQSeries queues.
Before you upgrade the connector to enable the ALE Module to process IDocs, you must complete the processing of current files in the event and WIP directories. Also, check the archive directory for failed and unsubscribed events.
To complete the processing of current files in the event and WIP directories:
$CROSSWORLDS/connectors/SAP/ale/events $CROSSWORLDS/connectors/SAP/ale/wip
%CROSSWORLDS%\connectors\SAP\ale\events %CROSSWORLDS%\connectors\SAP\ale\wip
To complete processing of any failed and unsubscribed events:
$CROSSWORLDS/connectors/SAP/ale/archive
%CROSSWORLDS%\connectors\SAP\ale\archive
Once these directories are clear, apply the upgrade and follow the configuration instructions in:
The IBM WebSphere Business Integration Adapter for mySAP.com is delivered as a Java-based connector (connector version 4.0.0 and later). In previous releases, the connector was written in C++. The directory structure is \connectors\SAP.
The following procedure is for upgrading a C++ version of the connector to the Java version of the connector.
For example, \connectors\SAP becomes connectors\SAP.old.
For example, \connectors\messages\SAPconnector.txt becomes \connectors\messages\SAPconnector.txt.old.
Modify the connector shortcut to point to the start_SAP.bat file in the connector directory. For example, if you are using the connector that supports SAP R/3 version 4.x, modify the shortcut to point to the connector startup file \connectors\SAP\start_SAP.bat.
