This topic summarizes what is new in this release of Message Service Client for C/C++.
The following sections summarize the key enhancements.
Client Auto Reconnect
WebSphere MQ V7.0 supports Client Auto Reconnect. An application reconnects automatically, without writing any additional code, by configuring a number of components. Auto-reconnection is inline, that is, the connection is automatically restored at any point in the client application program, and the handles to open objects are all restored. In previous releases of WebSphere MQ, this feature was not available. Manual reconnection requires the client application to recreate a connection and reopen objects.
Message Service Clients for C/C++ has been changed to exploit this new feature in WebSphere MQ V7.0. See Automatic WMQ client reconnection through XMS for details.
Addition of a new property XMSC_WMQ_RESOLVED_QUEUE_MANAGER_ID
A new property XMSC_WMQ_RESOLVED_QUEUE_MANAGER_ID is provided for getting the Unique ID of the queue manager. This property is read-only for connection object. Using this property application can get the ID of the queue manager that was connected to. See XMSC_WMQ_RESOLVED_QUEUE_MANAGER_ID for details of this property.
The XMS sample applications
Few samples are provided which demonstrate some of the features of XMS when connecting WMQ, WPM and RTT. You can use them to understand the usage of the XMS API.
XMS support for more operating systems
Refer to Operating environments for details of the supported operating environment.
