DFS3323E TRANSACTION REQUEST WAS DISCARDED BY BACKEND IMS xxxxxxxx DUE TO MAX TPIPE CONDITION

Explanation

The following explanation applies to non-Fast-Path transactions only.

IMS shared-queues back-end IMS detected a tpipe flood condition for an OTMA front-end initiated transaction at the application GU time. The limit, which is specified in the OTMA client descriptor, can be the MAXTP limit for an OTMA client or for DFSOTMA.

In the message text:

xxxxxxxx
IMS ID for the shared-queues back-end IMS.

This message is issued only when both front-end and back-end IMS systems have the MAXTP enhancement APAR PM71035 applied.

System action

IMS shared-queues back-end system discards this transaction without stopping it. This DFS3323E message is sent to the front-end IMS for OTMA client.

Programmer response

Issue the /DISPLAY OTMA command to view the TPCNT value, which is the total TPIPEs in use, and the MAXTP value, which is the TPIPE limit specified in the OTMA client descriptor. You can issue the IMS /CHECKPOINT command three times to force the tpipe cleanup so that idle tpipes in the system can be deleted.
