IMS LOG56FA Field TPMGU=1 after a LOG08 created

In the record x'56FA' of the LOG, the field TPMGU=2 after the creation of a LOG08. Even if the region is in PWFI and that the LOG08 is created because of the PLCT. So we can't use the field TPMGU to count the number of messages processed.

Request IBM to add EXPRTIME= for IMS Fast Path transactions

When Fast Path transactions are not processing quickly enough they can back up in IMS, increasing the storage utilized to contain control blocks associated with them. If an IMS expiration value is set, transactions that aren't processed before tha...

Reuse of DB2 connections and DB2 prepared statements in IMS JMP regions

Java applications running in an IMS JMP region have to reestablish the DB2 connection for each input message they process. Because of this prepared statements also cannot be reused when processing the next input message. They have to be prepared a...

Specify OTMA Destination Descriptors for TYPE=MQSERIES in DFSYDTx in shared PROCLIB

Implementation of TYPE=MQSERIES descriptors in DFSYDTx member have some drawbacks when using a shared PROCLIB.In an IMSplex with two MQ members, one in each LPAR with different names, you have to define the descriptor for both in the same DFSYDTx ...

Change/increase MAXSOC for IMS Connect dynamically

The total number of sockets that IMS Connect supports across all TCP/IP ports at the same time is set by the MAXSOC parameter in the TCPIP configuration statement of the IMS Connect configuration member. If the number of sockets reaches the maximu...

Reduce IMS ECSA Consumption when using DC Mon on busy systems.

When DC Monitor is started for the first time on a busy IMS system, we observe ECSA growth of several MB, which is not released when DC Monitor is stopped.

IMS should optionally autonomically calculate TPIPE limits, instead of making clients calculate what their MAXTP parameter should be.
