Use the Datastores and Datastore Groups tab
in Status Monitor to perform management tasks on IMS data
stores from the IMS Connect Extensions
Operations Console. Use this facility to start and stop IMS
data stores, suspend and resume routing to a data store, and to dynamically update a data stores
capacity weight rating (CWR) in response to periods of changing demand.
-
Open the Datastores or Datastore Groups
tab.
A list of IMS data stores is displayed. In the
following example, a filter has been applied to highlight the routing status of each data store.
Figure 1. Viewing the status of IMS data stores in the IMS Connect Extensions
Operations Console for z/OS® Explorer.
Use the following columns to review the status of each IMS data store:
- Status
- The status of the data store. A data store may be in one of the following states:
- Green circle (
)
- The data store is active.
- Yellow diamond (
)
- The data store is experiencing a flood condition.
- Red square (
)
- The data store is inactive.
- IMS Status
- This field shows the availability of an active IMS™ system
for OTMA transactions. If the ICON status value is inactive or disconnected,
IMS Status will be blank. If the ICON status value is
active, the possible values of IMS Status are:
- Normal
- The IMS system is available for work.
- MemberFloodWarn
- The datastore is in a Member Flood Warning state.
- MemberFloodSevr
- The datastore is in a Member Flood Severe state.
- GlobalFloodWarn
- The datastore is in a Global Flood Warning state.
- GlobalFloodSevr
- The datastore is in a Global Flood Severe state.
- Unknown
- The target IMS system is V9 or earlier.
See IMS Communications and Connections for
more information on the Degraded (Warning) and Unavailable (severe) flood states.
- Routing Status
- The status of the IMS data store as a candidate for OTMA routing in IMS Connect Extensions. A data store may be in one of the following routing
states:
- Normal
- The data store is potentially a candidate for routing.
- NormalWLB
- The data store is potentially a candidate for routing, and workload balancing is active.
- Degraded
- The data store might be a candidate for routing but only if there are no other candidates in
Normal state. This could be due to a warning-level IMS status.
- Unavailable
- The data store is not a candidate for routing. This could be due to a severe-level IMS status.
- SusCWRZero
- The data store has been suspended as a candidate for routing. Workload balancing is active and
the data store has a capacity weight rating of zero.
- Suspended
- The data store has been suspended as a candidate for routing. The data store has been drained
without the autoresume option. The data store might be stopped (see
ICON Status).
- SusAutoRes
- The data store has been suspended as a candidate for routing. It will automatically resume
routing when the data store has been stopped and then becomes active again.
- AutoRes or AutoResume
- The data store is stopped but if it is started it will automatically become a candidate for
routing.
- Waiting reply
- A count of pending responses for each data store.
-
Right-click on a data store to see a list of available actions:
Option |
Description |
Start |
Start the data store. |
Stop |
Stop the data store. |
Route Drain |
Suspend routing to the IMS data store. The data store
is withdrawn as a candidate for OTMA routing and is drained of in-progress transactions
(which are allowed to complete normally). Use the Waiting reply column to
monitor the number of pending responses. When the IMS data store has a Waiting
Reply count of 0, use the Stop action to
stop the data store.Important: The drain facility only works on messages handled by IMS Connect Extensions OTMA rules-based routing. It does not
work on messages that circumvent a routing rule or with exits customized with their
own routing mechanisms. Rejecting transactions for data
stores with no OTMA routing rule in the IBM® IMS Connect Extensions User's Guide..
|
Route Drain with AUTORESUME |
Suspend routing to the IMS data store until an IMS data store available event record
(X'10') is received at which point routing is automatically resumed. |
Route Resume |
Resume routing to the IMS data store (if routing was suspended). The IMS data store is once again a candidate for OTMA routing. |
Update Capacity Weight |
Change the processing capacity (capacity weight) for the selected IMS data store. Use this feature to redistribute workloads in response to periods of demand. Enter a new capacity weight value, click Next, and then click Finish. To retain
the current value, click Back, select No Change, and
then click Cancel. |

Operations Console for z/OS Explorer
Note: If Show confirmation on Stop/Start is selected, a confirmation dialog
is displayed before the data store is updated.
