Data Set Access Validation

TSO users do not automatically have access to data sets starting with their ACID. The Security Administrator must establish ownership by adding the data set prefix to an ACID and then permitting it to the user. This can be facilitated by using masking.

For detailed information about TSO security features, see the Implementation: TSO Guide.
