Using MQSC commands

For information on how you use MQSC commands, see Performing local administration tasks using MQSC commands.

Syntax diagram

START CHINIT

Notes:

• ¹ Valid only on z/OS when the queue manager is a member of a queue sharing group.

Usage notes

1. The command server must be running.
2. Although START CHINIT is permitted from CSQINP2, its processing is not complete (and the channel initiator is not available) until after CSQINP2 processing has finished. For these commands, consider using CSQINPX instead.
