Changes for this edition (SC34-6061-03)
This edition contains updates related to the following new features:
- Dynamic increase of cluster cache size (WebSphere MQ for z/OS only).
The MQXCLWLN call is now supported on z/OS. A new cluster cache configuration
option allows the cluster cache to expand dynamically if required. For related
information, see pagemqxclwln.
- Improved workload management for message distribution.
New rank, priority, use-queue, most recently used, and weight
attributes for queues, queue managers and cluster channels provide better
control over workload distribution. This allows greater flexibility in the
distribution of messages within clusters and around intersecting clusters,
easier creation of backup or standby networks (where these queue managers
are only used when all 'normal' queue managers are unavailable), easier restriction
of number of active outbound channels, easier channel weighting to ensure
that more powerful machines are sent more work by means of a new channel weighting
factor. For related information, see Workload balancing attributes.
- Support for IP version 6 hexadecimal addresses. Support is now provided
for IPv6 (Internet Protocol version 6). IPv6 removes a number of problems
associated with IPv4; more IP addresses, improvements in routing, automatic
network configuration. For related information, see the WebSphere MQ Migration Guide.
- New
Java-based WebSphere MQ Explorer GUI. The new WebSphere MQ Explorer is
an Eclipse-based user interface that can run on multiple platforms. It was
developed in Java.
