SharingConversations (MQLONG)
This field specifies the maximum number of conversations that can share a channel instance associated with this channel.
This field is used on client connection and server-connection channels.
A value of 0 means that the channel operates as it did in versions earlier than IBM® WebSphere® MQ 7.0 with respect to the following attributes:
- Conversation sharing
- Read ahead
STOP CHANNEL(<channelname>) MODE(QUIESCE)
- Heartbeating
- Client asynchronous consumption
A value of 1 is the minimum value for IBM MQ V7.0 behavior. Although only one conversation is allowed on the channel instance, read ahead, asynchronous consumption, and the Version 7 behavior of CLNTCONN-SVRCONN
heartbeating and quiescent channel stopping are available.
This is an input field to the exit. It is not present if Version
is less than MQCD_VERSION_9.
The default value of this field is 10.
Note:
MaxInstances
and MaxInstancesPerClient limits applied to a channel restrict the number of channel instances, not the number of conversations that might be sharing those instances.
