Excessive Access Queries

For CA ACF2 and CA Top Secret systems, each call to OPSECURE returning a data set access violation message counts as a real access violation. CA ACF2 may cancel the current job or TSO ID for excessive data set access violations. For this reason, avoid calling OPSECURE with every possible data set name to try to find out which data sets you can access. For more information about data set access validation, see the appropriate CA ACF2, CA Top Secret, or RACF guides.
