Description:

Release 1.12 of z/OS made the usage of the XTIOT optional with the introduction of the NON_VSAM_XTIOT parameter.

Is there a recommendation for CA-IDMS?

Solution:

Yes.

Most sites would not need the XTIOT, however some do have CVs with enough DDNAMES that it can be necessary.

In any case, to be consistent with the way CA-IDMS worked prior to z/OS 1.12, the NON_VSAM_XTIOT parameter should be set to YES.
