The default value means the WIS process will retry 3 times if it failed to find the work items from the staffo database table.
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 the 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. To find the new records in the table, you can configure this attribute to define the maximum number of retry times to retrieve the newly added work items.
