PH39257: OTMA ROUTING LIST ENHANCEMENT

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• IMS Connect Extensions OTMA routing involving a routing list
  that specifies multiple IMS subsystems in a shared queue group
  can generate a lot of Tpipes. In a shared queue environment,
  multiple front-end tpipes (1 for each member) can be created
  and each of those generates multiple back-end Tpipes (1 for each
  of the other members). This may consume a lot of virtual
  storage.

Problem conclusion

• OTMA Routing Lists are enhanced to include a new option to
  always route to  the first available datastore in list order.
  Workload balancing allows IMS Connect Extensions to redirect
  incoming transaction requests to IMS data stores according to
  their capacity weight rating (CWR), thereby balancing the
  transaction workload across multiple IMS systems and ensuring
  both availability and responsiveness for the remote client. If
  the routing list definition has the "use first" option.active
  then workload balancing is not used. The one exception to this
  is if the datastore has a CWR=0 in which case it is considered
  to be unavailable.
