IBM MQ naming restrictions

The naming restrictions for IBM MQ queues, queue managers, and queue-sharing groups are more restrictive than those that apply to equivalent objects in WebSphere Application Server. Use this information to help we administer the WAS objects, so that the names of these objects can be passed successfully to and from IBM MQ.

Rules for naming IBM MQ objects

• An IBM MQ object cannot have the same name as any other object of the same type.
• Names in IBM MQ are case sensitive.
• In IBM MQ, the names of queues can have up to 48 characters. The names of queue managers can have also have up to 48 characters, except in the case of IBM MQ for z/OS, where both queue manager and queue sharing group names are limited to four non-blank characters.

• The character set to use for naming all IBM MQ objects is as follows:
  • Uppercase A-Z
  • Lowercase a-z (but there are restrictions on the use of lowercase letters for z/OS console support)
  • Numerics 0-9
  • Period (.)

  • Forward slash (⁄).

  • Underscore (_)
  • Percent sign (%).

• Leading or embedded blanks are not allowed.

• Any structure to the names (for example, the use of the period or underscore) is not significant to the queue manager.
