Local fix
Problem summary
**************************************************************** USERS AFFECTED: MQ Appliance users operating with an HA/DR configuration. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: HA queue managers that are also configured for DR had no tolerance to transitory ping failures to their DR partner. HA/DR Queue Managers regularly perform a ping to their DR partner's heartbeat interface and intermittent failures could cause queue managers fail over unwantedly.
Problem conclusion
The code has been modified to monitor the connection state of the data replication component to minimize use of network pings and alleviate false positives. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 CD 9.1.3 v9.1 LTS 9.1.0.3 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
