Channel attributes

This section describes the channel attributes held in the channel definitions.

This information is product-sensitive programming interface information.

You choose the attributes of a channel to be optimal for a particular set of circumstances for each channel. However, when the channel is running, the actual values might have changed during startup negotiations. See Preparing channels.

Many attributes have default values, and you can use these values for most channels. However, in those circumstances where the defaults are not optimal, see this section for guidance in selecting the correct values.

Note: In WebSphere® MQ for IBM® i, most attributes can be specified as *SYSDFTCHL, which means that the value is taken from the system default channel in your system.
