SecurityExit (MQCHARn)

This field specifies the channel security exit name.

If this name is nonblank, the exit is called at the following times:
  • Immediately after establishing a channel.

    Before any messages are transferred, the exit is given the opportunity to instigate security flows to validate connection authorization.

  • Upon receipt of a response to a security message flow.

    Any security message flows received from the remote processor on the remote machine are given to the exit.

  • At initialization and termination of the channel.

See MQCD - Channel definition for a description of the content of this field in various environments.

The length of this field is given by MQ_EXIT_NAME_LENGTH.

Note: The value of this constant is environment-specific.
