The ZONERENAME command

With the ZONERENAME command, you can assign a new name to an existing target zone or distribution zone in an SMPCSI data set. You can also:

Change a distribution zone to a target zone.
Change the default OPTIONS entry name.
Change the name of the related zone.
Have SMP/E add a ZONEINDEX subentry for the renamed zone, if it is in a different CSI from the one containing the "old" name of the zone.

Note: ZONERENAME does not rename the SMPCSI data set containing the zone. It only renames the SMP/E zone inside the SMPCSI data set.

You may want to use the ZONERENAME command in some of the following situations:

If the current name of a zone does not conform to naming conventions of the establishment controlling the zone, and you want to assign a new name to the zone without going through the overhead required to do a ZONEMERGE followed by a ZONEDELETE.
If you create a new set of target libraries during system generation and need a target zone to describe them, you have two choices. You can use the ZONEMERGE command to create the target zone (see Examples for further information), or you can make a copy of the CSI containing the distribution zone. Then, using the ZONERENAME command, you can rename the distribution zone in the CSI copy to your new target zone name, change the zone type to TARGET, and connect it to the original distribution zone.
If you have made a copy of a CSI data set and want to access the copied zones through an existing global zone. Assuming that the zones in the original CSI are already accessed through that global zone, you cannot also access the zones in the copy, because there can be only one ZONEINDEX entry in the global zone for each unique zone name.
In this case, you want to rename the zone in the CSI copy, and then connect the renamed zone in your global zone. This procedure can be used to make a working copy of a zone under a different name for testing purposes without the overhead required to do a ZONEMERGE.
