Enabling full-function single-step HASH Check option

To start single-step HASH Check while the Image Copy function creates image copies, you need to prepare a cataloged procedure, and specify additional DD statements and ICEIN control statement keywords in FABJMAIN JCL.

1. Prepare a cataloged procedure for single-step HASH Check.
   Use the IBM® supplied cataloged procedure that is shown in the following figure or prepare a similar procedure of your own.

   //FABPICHE PROC HPSLIB='HPS.SHPSLMD0',          HPS LOAD LIBRARY
   //             RESLIB='IMSVS.SDFSRESL',         IMS RESLIB
   //             DBDLIB='IMSVS.DBDLIB',           IMS DBD LIBRARY
   //             HPSSRC='HPS.SHPSSAMP(FABPVSAM)', HPS SAMPLE JCL LIBRARY
   //             PRTBLK=6118   (133*46)       BLKSIZE OF PRINT DATA SETS
   //*-------------------------------------------------------------------*
   //HDPCPRO EXEC PGM=FABJMAIN
   //STEPLIB   DD DISP=SHR,DSN=&HPSLIB
   //          DD DISP=SHR,DSN=&RESLIB
   //*-------------------------------------------------------------------*
   //* FOR IMS DATA SETS
   //*-------------------------------------------------------------------*
   //DFSRESLB  DD DISP=SHR,DSN=&RESLIB
   //IMS       DD DISP=SHR,DSN=&DBDLIB
   //DFSPRINT  DD SYSOUT=A,DCB=BLKSIZE=&PRTBLK,OUTLIM=0
   //SYSPRINT  DD SYSOUT=A,DCB=BLKSIZE=&PRTBLK,OUTLIM=0
   //*-------------------------------------------------------------------*
   //* REPORTS
   //*-------------------------------------------------------------------*
   //ICEPRINT  DD SYSOUT=A,DCB=BLKSIZE=&PRTBLK,OUTLIM=0
   //PRIMAPRT  DD SYSOUT=A,DCB=BLKSIZE=&PRTBLK,OUTLIM=0
   //STATIPRT  DD SYSOUT=A,DCB=BLKSIZE=&PRTBLK,OUTLIM=0
   //VALIDPRT  DD SYSOUT=A,DCB=BLKSIZE=&PRTBLK,OUTLIM=0
   //EVALUPRT  DD SYSOUT=A,DCB=BLKSIZE=&PRTBLK,OUTLIM=0
   //SNAPPIT   DD SYSOUT=A,DCB=BLKSIZE=&PRTBLK,OUTLIM=0
   //SUMMARY   DD SYSOUT=A,DCB=BLKSIZE=&PRTBLK,OUTLIM=0
   //SYSUDUMP  DD SYSOUT=A,DCB=BLKSIZE=&PRTBLK,OUTLIM=0

2. Prepare FABJMAIN JCL by following the steps described in Taking image copies.

   To enable the Single-step HASH Check option, specify HDPC=Y and additional DD statements that are required for the single-step HASH Check option. For a list of additional DD statements for HASH Check, see DD statements for the full-function database HASH Check option.

   Note: Do not specify the DBDEFCTL DD statement in FABJMAIN JCL. If specified, it is regarded as multiple-step HASH Check.

   JCL examples are provided in Examples for enabling the HD Pointer Checker HASH Check option.

3. Submit the JCL.
