In all stages the getUMAP, getGMAP, and R-usermap callable services will report unexpected ICHEINTY and RACROUTE return codes (non-zero return codes other than indicating the profile was not found) with a LOGREC entry. Additionally, if locating an alias index entry fails but a mapping profile is found for a database at Stage 2, the callable service will write an entry to the LOGREC data set with a return code of X'0000000C' and a reason code of X'00000000'. The presence of these LOGREC entries indicates that the alias index is not complete and must be corrected before moving to Stage 3. The variable data for services IRRRGM01 (GID to group name mapping service), IRRRUM01 (UID to user ID mapping service) and IRRRIM00 (application ID to RACF® user ID mapping service) serves as the RACF group name or user ID and as the entry name specified on the locate request for the alias index entry.
