VSE Data Set Access Rules

You can also write access rules to protect VSE files that can be accessed through CMS. The syntax of the access rule sets is the same as for OS/390 data sets.

$KEY(PAYROLL)
 MASTER.DATA UID(APPMGRTLCAMS) READ(A)
 MASTER.DATA UID(APPPRGTLCAMS) READ(A) UNTIL(01/01/99)

This rule set specifies read access for the VSE file PAYROLL.MASTER.DATA. The first rule entry allows read access to user APPMGRTLCAMS. The second grants read access to user APPPRGTLCAMS until (and including) January 1, 1997.

Access rules allow VSE filenames of up to 44 total characters and up to eight characters per index level. If you want to protect VSE files with nonstandard names, you must insert your own code to convert those names to standard ones for CA ACF2 for VM validation. You can implement this code through the
CA ACF2 for VM data set prevalidation exit.
