What's new in
WebSphere MQ v7.0.1
(This could also give difference between WMQ V6 and v7)
1. Introduced Multi-Instance Queue Managers:
Enables automatic
failover to a standby Queue Manager instance in the Multi-Instance Active
Queue Managers event of an incident or planned outage. This means that in the
event of the failure of the MQ queue manager, or the machine it is running on,
a standby instance will automatically takeover and client connections will be
transferred to this new instance. The key technical feature in achieving this
is the placement of the queue manager data, including its logs, in networked storage.
This means that all instances of a queue manager can access the same data.
Multiple instances of a queue manager can then be defined on different machines
that all have access to the networked file system. It should be noted that the
instances must all be running on the same operating systems.
2. Integration of Publish
/ Subscribe:
Pub/Sub Functionality has been completely integrated into
WMQ from WMB starting from Version WMQ v7.
3. Automatic Client Reconnect:
Provides
Client-connected applications with automatic detection of failures and
reconnects to alternative Queue Managers. With Auto-reconnection, the
connection is automatically restored and the handles to open objects are all
restored after a failure. Uses the list of addresses in CONNAME to find queue
manager.
4. Enhanced Governance:
Service Definition
wizard generates WSDL describing MQ apps. The service definition wizard simplifies the
process of creating WMQ service definitions and is integrated into the WMQ
Explorer.
5. Enhanced SSL Security:
Supports certificate
checks with Online Certificate Status Protocol (OCSP) as well as to Certificate
Revocation Lists (CRL). Online Certificate Status Protocol (OCSP) determines whether
a certificate has been revoked, and therefore, helps to determine whether the
certificate can be trusted.
6. Enhanced .NET support:
Provides IBM Message
Service Client for .NET developers. Supports use of WebSphere MQ as custom
channel within Windows Communication Foundation.
