Notes
| • | With configured Oracle RAC, a commit transaction is divided into two actions: dequeue the REQUEST instruction by WISMBD and insert the new work items into the staffo table. These two actions are on two Oracle RAC instances. If the dequeue action completes before the committed new work items to the table is replicated to the second node, the WIS process may not be able to read the work items from the staffo table. |
If the retry function is enabled, the WISMBD will retry sending messages. Otherwise, the WIS treats it as a withdrawn message and ignores the request. A message similar to the following will be displayed in the WIS log:
1631-WARNING: <no matching entry found in the STAFFO table when the REQUEST message is processed>
In this case, you can set this attribute to 1 to switch on the retry function.
| • | By default, the retry function is enabled. If you need to create many work items that are quickly withdrawn either by the withdraw action or closing case, the work items cannot be retrieved from the staffo database table. To expedite the WIS Mbox processing, you can configure this attribute to switch off the retry function. |
