Periodical Tasks
Periodical tasks that needs to be performed frequently in order to ensure that the software runs smoothly with optimal performance.
In the context of SAP NetWeaver Gateway some cleanup jobs might be necessary on the SAP NetWeaver Gateway hub system. You can find the relevant activities in the Implementation Guide (IMG): In transaction
SPRO open the
SAP Reference IMG and
navigate to
SAP NetWeaver 
Gateway OData Channel Administration Cache Settings 
.
The tasks need to be performed in regular intervals. The frequency specified depends on the load in your system and therefore may vary. A periodical cleanup of all processed messages is recommended to avoid a waste of disk and memory space. You might consider a frequency of once every month.
There are several cleanup scenarios, for example:
|
Scenario |
Description |
|---|---|
|
/IWFND/DEVICE_MAMANGER |
Cleanup for Device Manager |
|
/IWFND/DOCUMENT_PUBLISHER |
Document Publisher |
|
/IWFND/OIL |
OIL - Object ID List |
|
/IWFND/QRC_AUTO |
QRC - Query Result Cache - For Scheduler |
|
/IWFND/ROLE_SYNC_ALL |
Role Sync Cleanup - All |
|
/IWFND/ROLE_SYNC_CAUTIOUS |
Role Sync Cleanup - Cautious Method |
Caching is available in the following places:
-
in the SAP NetWeaver Gateway hub system
-
in the client browser (and probably also in the internet proxy)
For development we recommend that caching on the SAP NetWeaver Gateway hub system is disabled.
For more information on metadata caching, see Metadata Cache.
For information on recommended cache settings per cleanup scenario see the corresponding application documentation.
