by other processes. When the WLM timeout is reached the thread is killed resulting in the process being
killed.
IBM Tivoli Identity Manager can initiate long-running IIOP requests during processes like reconciliations.
To allow long-running reconciliations to complete we recommend disabling the WLM timeout.
Determining the values
wlm_timeout – The time in seconds that IIOP requests wait on the queue before being
terminated. Default value: 300. Recommended value: 0 (disabled).
Setting the values
1) Open the Administration Console.
2) Expand the Servers list in the navigation pane.
3) Select Application Servers in the navigation pane.
4) Select the server to manage.
5) Select Container Services.
6) Select ORB Service.
7) Select z/OS additional settings.
8) Change WLM timeout to wlm_timeout.
9) Repeat this procedure for each IBM Tivoli Identity Manager server.
Stop and restart each Application Server for these changes to take effect.
2.3 Message driven bean (MDB) request timeout The message driven bean (MDB) request timeout controls how much time MDBs should be limited to.
Policy evaluations can often run over the default timeout and should be increased.
Determining the values
mdb_request_timeout – The time in seconds allotted to MDB requests. Default value: 1200.
Recommended value: 7200.
Setting the values
1) Open the Administration Console.
2) Expand the Servers list in the navigation pane.
3) Select Application Servers in the navigation pane.
4) Select the server to manage.
5) Select Custom Properties.
6) Change the value of control_region_mdb_request_timeout to mdb_timeout.
7) Repeat this procedure for each IBM Tivoli Identity Manager server.
Stop and restart each Application Server for these changes to take effect.
2.4 Transaction timeout Complex or long-running transactions within IBM Tivoli Identity Manager can often run past the default
transaction timeout. It is recommend that the default transaction timeout be increased.
Determining the values
transaction_timeout – The time in seconds before a transaction timeouts. Default value: 300.
Recommended value: 12000.
