PI77965: INTEGRATION SERVER POLLING TOO OFTEN FOR ADMIN REQUESTS AND CREATING TO MANY MQ CONNECTIONS

APAR status

• Closed as program error.

Error description

• Integration server processes wait on interprocess communications
  for admin requests and look in a file system directory for
  direct deploys.  Currently these are happening more often than
  our standard 5 seconds interval and so leads to a higher cpu
  usage for idle integration servers than previous releases.
  
  To check for Queue Manager availability of Integration Nodes
  configured with a default Queue Manager, an MQ connection
  is frequently opened and tested. This leads to excessive
  CPU usage from the frequent MQCONN/MQDISC calls.
  

Local fix

  USERS AFFECTED:
  All users of IBM Integration Bus V10.0 who configure a default
  Queue Manager.

Problem conclusion

• The product has changed to poll every 5 seconds for admin
  requests and maintain 1 MQ connection per process and test its
  viability.
