If I am using CA-Gener/OL in a multiple region system, can all SGTLIBs be shared?
As long as you follow VSAM file sharing rules, all SGTLIBs except for SGTLIBC (the control file) may be shared. (For each individual region, you must have a unique control library which is generally named SGTLIBC). If you do not have an SGTLIBC (for example, if you used the Optional Patch from the CA-Gener/OL Installation and Implementation Guide to use SGTLIB1 or another library as the control file) the same rule will apply. Note that SGTLIBU and SGTLIBP cannot be used as control files.
