The RACF® R_dceinfo callable service retrieves or sets the following fields from a user profile DCE segment:

• The DCE principal name associated with this RACF user
• DCE UUID of this user
• DCE cell name that this user is defined to (HOME CELL)
• DCE cell UUID that is associated with DCE cell that this user is defined to (HOMEUUID)
• A flag byte that indicates whether z/OS DCE creates a DCE security context (autologin) automatically

The action performed by this callable service is based on the function code passed by the caller in the R_dceinfo parameter list.

• When the function code is set to EXTRACT, R_dceinfo retrieves the information requested from the user's DCE segment.
• When the function code is set to REPLACE, R_dceinfo replaces the fields that have been specified in the parameter list.
