Profile Modeling

Profile modeling enables RACF® or an installation exit routine to copy information (such as the access list, owner, and logging options) from an existing profile when defining a new profile. (The copied profile is not necessarily identical to the model profile. See Possible Changes to Copied Profiles When Modeling Occurs.) This copying greatly reduces the effort needed to create new profiles. The following are some ways to use profile modeling.

• A user can use the FROM operand (and related operands) on the RDEFINE, ADDFILE, and ADDDIR commands to copy information from an existing profile into the new profile. RACF uses the specified profile as a model when creating the new profile. However, profile segment information is not copied to the new profile.
• A user can use the FROM operand (and related operands) on the PERMIT, PERMFILE, and PERMDIR commands to copy the access list from one existing profile into another existing profile.
• If the preceding methods are not sufficient, an installation can also use a RACROUTE REQUEST=DEFINE exit routine to supply either the name of a model profile or the profile itself.
