For each data set eligible for the selection data set, ABA checks
whether the data set is cataloged, and attempts to obtain certain
catalog information. ABA should be installed in an APF-authorized
library for the following reasons:
- If any of the catalogs contain password protection, ABA may cause
the MVS™ catalog to prompt the
system operator for the password. Having APF authorization allows
ABA to bypass MVS catalog security
checking.
- APF authorization enables ABA to query catalogs that are RACF® protected and prevents ABENDs
caused by RACF authorization
failures.
