An MQCONN call was issued from a client to connect to a queue manager but the channel is not currently available.
Common causes of this reason code are:
The channel is currently in stopped state.
The channel has been stopped by a channel exit.
The queue manager has reached its maximum allowable limit for this channel from this client.
The queue manager has reached its maximum allowable limit for this channel.
The queue manager has reached its maximum allowable limit for all channels.
Maximum instances (MAXINST)
Specifies the maximum number of simultaneous instances of a server-connection channel that can be started.
This attribute can be set from zero through 999 999 999. A value of zero indicates that no client connections are allowed on this channel. The default value is 999 999 999.
If the value is reduced below the number of instances of the server-connection channel that are currently running, then the running channels are not affected. However, new instances are not able to start until sufficient existing ones have ceased to run.
This attribute is valid for server-connection channels only.
Maximum instances per client (MAXINSTC)
Specifies the maximum number of simultaneous instances of a server-connection channel that can be started from a single client.
This attribute can be set from zero through 999 999 999. A value of zero indicates that no client connections are allowed on this channel. The default value is 999 999 999.
If the value is reduced below the number of instances of the server-connection channel that are currently running from individual clients, then the running channels are not affected. However, new instances from those clients are not able to start until sufficient existing ones have ceased to run.
This attribute is valid for server-connection channels only.
