Consolidation of IMS logger parameters in the DFSDF`xxx` PROCLIB member

In IMS 15, the parameters that define the IMS logger function are consolidated into a new section, <SECTION=LOGGER>, in the DFSDFxxx member of the IMS PROCLIB data set. The LOGGER section of the DFSDFxxx PROCLIB member is mandatory.

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.

Migration considerations

IMS 15 is the first IMS release where the DFSDFxxx member of the PROCLIB data set is mandatory.
