Resolution

Checking the expansion of the procedures included in the DBREVERS job, in the distributed members  DMSSTPLB and DMSFILES there are 3 possible choices as reported below :  

//*        --- INCLUDE GROUP DMSSTPLB ---
//* TAILOR THIS SAMPLE MEMBER TO MEET YOUR REQUIREMENTS, AND THEN
//* COPY THE FINAL VERSION TO MEMBER NAME "DMSSTPLB" IN THE
//* PROCLIB YOU WILL USE FOR CA DISK.
//*
//* IN ORDER TO SUPPORT DMSAR AND OTHER STARTED TASKS, YOU WILL NEED
//* TO CREATE DMSFILES IN A SYSTEM PROCLIB.  YOU CAN CREATE ALTERNATE
//* COPIES IN ADDITIONAL PROCLIBS AND REFERENCE THEM USING THE
//* JCLLIB STATEMENT.
//*
//* CHOOSE ONE OF THE FOLLOWING ALTERNATIVES
//*
//* 1. SYMBOLICS "Q" AND "DCAI" FOR INSTALLED ELEMENTS,
//*    "C" AND "DCUS" FOR CUSTOMIZED MEMBERS
//*STEPLIB   DD   DISP=SHR,DSN=&C..T1.CCUWLOAD.DATACOM
//*          DD   DISP=SHR,DSN=&Q..LOADLIB
//*           DD   DISP=SHR,DSN=&DCUS..CUSLIB
//*           DD   DISP=SHR,DSN=&DCAI..CAAXLOAD
//*
//* 2. EXISTING SYMBOLICS "Q", "DCUS", "DCAI", FOR ALL LIBRARIES
//*STEPLIB   DD   DISP=SHR,DSN=&Q..LOADLIB
//*          DD   DISP=SHR,DSN=&Q..CUSLOAD
//*          DD   DISP=SHR,DSN=&DCUS..CUSLIB
//*          DD   DISP=SHR,DSN=&DCAI..CAAXLOAD
//*
//* 3. FIXED DATA SET NAMES
//*STEPLIB   DD   DISP=SHR,DSN=&Q..LOADLIB
//*          DD   DISP=SHR,DSN=CAI.DISK.CUSLOAD
//*          DD   DISP=SHR,DSN=CAI.ADRR.CUSLIB
//*          DD   DISP=SHR,DSN=CAI.ADRR.CAAXLOAD
//*        -------- END DMSSTPLB --------

 

//*        --- INCLUDE GROUP DMSFILES ---
//*---------------------------------------------------------------
//* NON VENGONO PASSATI I FILES DA QUESTA PROCEDURA MA VENGONO
//* RICHIAMATI DIRETTAMENTE DAI JCL
//*---------------------------------------------------------------
//* TAILOR THIS SAMPLE MEMBER TO MEET YOUR REQUIREMENTS.
//* COPY THE FINAL VERSION TO MEMBER NAME "DMSFILES" IN THE
//* PROCLIB YOU WILL USE FOR CA DISK.
//*
//* IN ORDER TO SUPPORT DMSAR AND OTHER STARTED TASKS, YOU WILL NEED
//* TO CREATE DMSFILES IN A SYSTEM PROCLIB.  YOU CAN CREATE ALTERNATE

//*FILES     DD   DISP=SHR,DSN=&FILES
//* 
//*
//* 2. SEPARATE SYMBOLIC "F"
//*FILES     DD   DISP=SHR,DSN=&FILES
//* 
//*
//* 3. FIXED DATA SET NAME
//*FILES     DD   DISP=SHR,DSN=&FILES
//* 
//*        -------- END DMSFILES --------

 

If all the 3 options are commented in and used at the same time, they cause redundant allocations  :

ADSHR001 4541 CA HEALTH CHECKER INITIALIZATION FAILED, RC=00000008 RSN=00000008
 ADSDM175 4538 INITIALIZATION OF HEALTH CHECKS FAILED: MODULE ADSHR001 FAILED WITH RC= 4 RS= 8
ADSDC010 4302 FILES DATA SET SYSXXX.CA.DISK.TEST.FILES IS ASSIGNED TO CA-DATACOM DBID 651
ADSDC010 4302 FILES DATA SET SYSXXX.CA.DISK.TEST.FILES IS ASSIGNED TO CA-DATACOM DBID 651
ADSDC010 4302 FILES DATA SET SYSXXX.CA.DISK.TEST.FILES IS ASSIGNED TO CA-DATACOM DBID 651
 ADSDC696 4424 UNABLE TO ESTABLISH DATABASE IDENTITY

So only one choice should be commented in and used, according to the explanation provided.
