Issue/Introduction

Description

When the CA Scheduler JM subsystem name (SUBSYS=id) is changed, the CA Scheduler data base must be updated to recognize the new subsystem name. This knowledge document describes what needs to be done to update the CA Scheduler data base.

Solution

The following procedures assume that the current subsystem name is SCHD (SUBSYS=SCHD), and the new subsystem name is SCHB (SUBSYS=SCHB).

1. Shutdown the CA Scheduler STC, and ensure that all users are logged off from the CA Scheduler Online.
2. Backup the current CA Scheduler system using the CA Scheduler CAJUTIL0 proc. Sample backup JCL is as follows:

//STEP1  EXEC CAJUTIL0//$$SCHD  DD DUMMY//SYSPRINT DD SYSOUT=*//CAIJBST  DD DSN=hlq.caijmst.backup,DISP=(,CATLG),//            SPACE=(CYL,(xx,y),RLSE),UNIT=SYSDA//CAIJBRK  DD DSN=hlq.caijtrk.backup,DISP=(,CATLG),//            SPACE=(CYL,(xx,y),RLSE),UNIT=SYSDA//CAIJBTG  DD DSN=hlq.caijstg.backup,DISP=(,CATLG),//            SPACE=(CYL,(xx,y),RLSE),UNIT=SYSDA//CAIJBCM  DD DSN=hlq.caijdcm.backup,DISP=(,CATLG),//            SPACE=(CYL,(xx,y),RLSE),UNIT=SYSDA//SYSIN    DD   * BACKUP CAIJMST BACKUP CAIJTRK BACKUP CAIJSTG BACKUP CAIJDCM/* 

3. Follow procedures in the Systems Programmer Guide Section10.1.1 "IMPLEMENT MULTIPLE COPIES" up to item 8.

1. Change CAS9 Main FUNC=REINIT, SUBSYS=SCHB
2. Add //$$SCHB to the following procs:  CASCHD, CAJUTIL0, CAJUCMD0, CAICHERL
3.  Change CA Scheduler logon CLIST:

   ISPEXEC SELECT PGM(CAJIMAIN) NEWAPPL(SCHD) PASSLIB PARM( HB )

• Rename the existing CA Scheduler data sets, and allocate new ones:

//RENAME   EXEC PGM=IDCAMS,REGION=0M//SYSPRINT DD   SYSOUT=*//SYSIN    DD   *  ALTER cai.schd.data -    NEWNAME(cai.schd.data.old)  ALTER cai.schd.hist -    NEWNAME(cai.schd.hist.old)  ALTER cai.schd.index -    NEWNAME(cai.schd.index.old)/*//*  ALLOCATE & INITIALIZE NEW DATASETS//*//INIT     EXEC PGM=DBUTLTY,REGION=4M,COND=(0,LT)//STEPLIB  DD   DISP=SHR,DSN=cai.datacom.cuslib//         DD   DISP=SHR,DSN=cai.datacom.cailib//SYSPRINT DD   SYSOUT=*//CXX      DD   DISP=SHR,DSN=cai.datacom.cxx//ACH430   DD   DISP=(NEW,CATLG),//         DSN=cai.schd.data,//         UNIT=SYSDA,//         VOL=SER=nnnnnn,//         SPACE=(CYL,(xx,y)),//         DCB=(DSORG=PS,RECFM=F,LRECL=4096,BLKSIZE=4096)//HST430   DD   DISP=(NEW,CATLG),//         DSN=cai.schd.hist,//         UNIT=SYSDA,//         VOL=SER=nnnnnn,//         SPACE=(CYL,(xx,y)),//         DCB=(DSORG=PS,RECFM=F,LRECL=4096,BLKSIZE=4096)//IXX430   DD   DISP=(NEW,CATLG),//         DSN=cai.schd.index,//         UNIT=SYSDA,//         VOL=SER=nnnnnn,//         SPACE=(CYL,(xx,y)),//         DCB=(DSORG=PS,RECFM=F,LRECL=4096,BLKSIZE=4096)//SYSIN    DD   *INIT AREA=IXX,DBID=430INIT AREA=ACH,DBID=430INIT AREA=HST,DBID=430LOAD AREA=ACH,DBID=430,FORMAT=NONE,SORT=1LOAD AREA=HST,DBID=430,FORMAT=NONE,SORT=1/*

• Restore the backup files created in Step 1 into the newly created SCHB subsystem.

//STEP1  EXEC CAJUTIL0//$$SCHB   DD DUMMY//SYSPRINT DD SYSOUT=*//CAIJBST  DD DSN=hlq.caijmst.backup,DISP=SHR//CAIJBRK  DD DSN=hlq.caijtrk.backup,DISP=SHR//CAIJBTG  DD DSN=hlq.caijstg.backup,DISP=SHR//CAIJBCM  DD DSN=hlq.caijdcm.backup,DISP=SHR//SYSIN    DD   * RESTORE CAIJMST RESTORE CAIJTRK RESTORE CAIJSTG RESTORE CAIJDCM/*
