Migration considerations for moving logger parameters to DFSDFxxx

IMS 15 includes migration considerations related to the consolidation of the IMS logger parameters into the mandatory LOGGER section of the DFSDFxxx member of the IMS PROCLIB data set.

The IMS logger parameters that were previously specified in the DFSVSMxx PROCLIB member are moved to the new LOGGER section of the DFSDFxxx PROBLIB member. Any logger parameters that are still specified in the DFSVSMxx member are ignored by the IMS system and not reported in the error log.

The ARC= and WADS= parameters, which were previously specified in the DFSPBxxx PROCLIB member or on the EXEC parameters of the control region JCL, are also moved to the DFSDFxxx PROCLIB member. If you specify ARC= or WADS= in DFSPBxxx or in the control region JCL, the specifications are ignored by the IMS system.
