This topic summarizes the naming restrictions for WebSphere MQ
queues, queue managers, and queue sharing groups. This information is useful
when you need to choose names in WebSphere Application Server that are compatible
with the WebSphere MQ queue manager naming restrictions. For example, it is
advisable to use a service integration bus name that is compatible with a
WebSphere MQ queue manager name.
Rules for naming WebSphere MQ objects
- A WebSphere MQ object cannot have the same name as any other object of
the same type.
- Names in WebSphere MQ are case sensitive.
- The names of queues, queue managers or (WebSphere MQ) queue-sharing groups
can have up to 48 characters.
- The character set to use for naming all WebSphere 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.
