Upgrading the connector for the ALE Module's management
of TIDs
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.
Attention: To enable the ALE Module to process IDocs to and from
the SAP application, you must upgrade the connector. However, it
is imperative that you allow the current IDoc processing cycle to
complete before upgrading the connector.
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:
- Temporarily halt the transmission of IDocs both to and from
the connector.
- Verify that there are no IDocs (files) in the following directories
when you upgrade:
Linux
$CROSSWORLDS/connectors/SAP/ale/events
$CROSSWORLDS/connectors/SAP/ale/wip
Windows
%CROSSWORLDS%\connectors\SAP\ale\events
%CROSSWORLDS%\connectors\SAP\ale\wip
To complete processing of any failed and unsubscribed events:
- Temporarily halt the transmission of IDocs both to and from
the connector.
- Verify the status of the IDocs (files) in the following directory
when you upgrade:
Linux
$CROSSWORLDS/connectors/SAP/ale/archive
Windows
%CROSSWORLDS%\connectors\SAP\ale\archive
- Correct any errors to the failed or unsubscribed events.
- Move the corrected file to the event directory for processing.
Note:
If, when using transaction SM58, you find unsuccessfully
processed IDocs in the SAP system, wait until the connector is upgraded
to resubmit these IDocs. After you complete the upgrade of the connector,
correct the errors and resubmit the IDocs for processing using the
new TID management.
Once these directories are clear, apply the upgrade and follow
the configuration instructions in:
