Optimizing WebSphere MQ

Optimizing WebSphere MQ

To optimize WebSphere MQ performance and improve throughput, configure the following tasks:
  • Tune the WebSphere MQ queue manager and queue manager logging parameters.
    The following table describes the WebSphere MQ tuning parameters:
    Parameter
    Description
    MAXUMSGS
    Queue manager parameter that specifies the maximum uncommitted messages. Limits the number of messages that applications can put on or retrieve from queues within a synchronization point.
    The session fails if the number of messages the PowerCenter Integration Service reads and writes from the message queue within a synchronization point exceeds this value.
    LogFilePages
    Log parameter that specifies the size of each primary and secondary log file.
    LogBufferPages
    Log parameter that specifies the amount of memory that is allocated to buffer records for log writes.
  • Use WebSphere MQ server libraries.
    If the WebSphere MQ server and the PowerCenter Server are on the same machine, back up the libpmmqdrvc.a file. Rename the file to libpmmqdrvc.bak. Then, rename the libpmmqdrvs.a file to libpmmqdrvc.a. You can find the files in the following directory: 
    <PowerCenter installation directory>/server/bin
