Problems resizing queue managers

You might encounter a problem where you have used the setmqsize command to increase the size of a queue manager's file system, but the size has not actually increased.

A queue manager is created with a 64 GB file system space by default, but you can use the setmqsize command to specify a different file system size for an existing queue manager.

The setmqsize command uses a two-stage operation when increasing the file system size. If the operation is interrupted before both stages have completed (for example, by a power failure) your queue manager can be left in the situation where it reports having a file system of the new size, but actually still has the old file system size.

To remedy this situation, re-run the setmqsize command, specifying the desired file system size.
