Specifying the maximum number of current channels

 

We can specify the maximum number of channels that can be current at one time. This is the number of channels that have entries in the channel status table, including channels that are retrying and channels that are stopped. Specify this using ALTER QMGR MAXCHL for z/OS, the queue manager initialization file for i5/OS, the queue manager configuration file for UNIX systems, or the WebSphere MQ Explorer. For more information about the values you set using the initialization or the configuration file see Configuration file stanzas for distributed queuing. For more information about specifying the maximum number of channels, see the WebSphere MQ System Administration Guide for WebSphere MQ for UNIX systems, and Windows systems, the WebSphere MQ for iSeries System Administration Guide book for WebSphere MQ for iSeries, or the WebSphere MQ Script (MQSC) Command Reference for WebSphere MQ for z/OS.

1. Server-connection channels are included in this number.

2. A channel must be current before it can become active. If a channel is started, but cannot become current, the start fails.
