Authorizing access to data sets

The IBM® MQ data sets should be protected so that no unauthorized user can run a queue manager instance, or gain access to any queue manager data. To do this, use normal z/OS® RACF® data set protection.

Table 1 summarizes the RACF access that the queue manager started task procedure must have to the different data sets.
