Message channel agent user identifier (MCAUSER)
This attribute is the user identifier (a string) to be used by the MCA for authorization to access IBM® WebSphere® MQ resources.
Note: An alternative way of providing a user ID for a channel
to run under is to use channel authentication records. With channel
authentication records, different connections can use the same channel
while using different credentials. If both MCAUSER on the channel
is set and channel authentication records are used to apply to the
same channel, the channel authentication records take precedence.
The MCAUSER on the channel definition is only used if the channel
authentication record uses USERSRC(CHANNEL).
This authorization includes (if PUT authority is DEF) putting the message to the destination queue for receiver or requester channels.
On IBM WebSphere MQ for Windows, the user identifier can be domain-qualified
by using the format, user@domain
, where the domain
must
be either the Windows systems domain
of the local system, or a trusted domain.
If this attribute is blank, the MCA uses its default user identifier. For more information, see DEFINE CHANNEL.
This attribute is valid for channel types
of:
- Receiver
- Requester
- Server connection
- Cluster receiver
