The File Access Validation determines whether the user has access to the dataset required by the job being verified.

The user being checked, who might not necessarily be the one performing the verification, is determined by the following criteria:

• the user that is specified by the USER keyword in the JOB statement
• in Control-M, the user that is specified by the OWNER field in the job definition
• in the CTJVER utility, the user that is specified by the USER statement
• in ISPF, the user that is specified in the CTJXVER P edit macro window (see Verification mode)
• the user that performs the verification

The authority validations checks are based on the DISP keyword in the DD statement as listed below:

• DISP=SHR - required read permission
• DISP=OLD - required update permission
• DISP=NEW - required create permission
• DISP=MOD and the file exists - required update permission
• DISP=MOD and the file is new - required create permission
• DISP=(…,DELETE) - required delete permission
• DISP=(…,UNCATLG) - required uncatalog permission

The READ, UPDATE, CREATE, DELETE and UNCATLG permissions are logical and depend on the security package that is installed and on the z/OS release.
