Merging SYSMOD entries

SYSMOD entries are merged when either CONTENT or FORFMID is specified on the GZONEMERGE command. If CONTENT is specified, SMP/E will consider all SYSMOD entries in the original global zone as candidates for merging. If FORFMID is specified, SMP/E will consider only the SYSMOD entries associated with the selected FMIDs for merging.

SMP/E reads through the original zone, gathering data on the candidate SYSMOD and HOLDDATA entries. For each candidate entry in the originating zone, SMP/E checks to see whether that entry exists in the destination zone.

If a SYSMOD entry is not found, then the entry from the originating global zone is stored in the destination global zone.
If a SYSMOD entry is found, processing continues to determine the higher level SYSMOD. If the originating global zone contains a higher or equal level of the SYSMOD than the destination global zone, then the entry from the originating global zone replaces the existing SYSMOD entry in the destination global zone. Any existing HOLDFIXCAT (or HOLDERR, HOLDSYS, and HOLDUSER) subentries from the destination global zone will be retained. If the destination global zone contains a higher level of the SYSMOD than the originating global zone, then processing continues to the next entry.
SMP/E uses the REWORK subentry of the global zone SYSMOD entry to determine if a SYSMOD in the originating global zone is at a higher level than the same-named SYSMOD in the destination zone. If the REWORK date of the SYSMOD in the originating global zone is more recent than the REWORK date of the SYSMOD in the destination global zone, then that SYSMOD is considered to be at a higher level in the originating global zone and would be merged.
If a SYSMOD entry in the originating global zone has a SOURCEID subentry that matches the name of the ORDER entry from which it originated, and that ORDER entry is being renamed because a like-named entry already exists in the destination global zone, then SMP/E ensures that the SOURCEID value matches the new name for the ORDER entry. To accomplish this it is necessary to process DEFINITION entries before CONTENT entries.
