What's new in IBM MQ 9.2.3 for Multiplatforms - Advanced entitlement only

General availability of Native HA for IBM MQ containers in Red Hat OpenShift

The native high availability (Native HA) capability provides a highly available queue manager, automatically recovering from failures in seconds. All recoverable IBM MQ data are consistently replicated across multiple sets of independent storage, preventing loss from storage failures and enabling failover across availability zones. A Native HA capability preview was delivered in IBM MQ 9.2.2, for clients deploying container-based queue managers to IBM Cloud Pak® for Integration 2021.1.1 in Red Hat® OpenShift® using the IBM MQ container. In IBM MQ 9.2.3, this configuration becomes available for production use as part of IBM Cloud Pak for Integration 2021.2.1.

Replicated Data Queue Manager (RDQM) kernel module serviceability enhancements

RDQM relies on DRBD to provide data replication. IBM MQ 9.2.3 delivers enhancements to help you ensure that you have loaded the correct DRBD kernel module to match the OS kernel version and to improve diagnostics.
