The CA DISK documentation has some information on this process in DBDELETE - Delete a Disk Database . That process does not delete the data sets.
First run the REMOVE step from that DBDELETE job and then run the steps below.
There are 10 tables in this base and all tables have SQL access enabled ( Read-only access) . SQL tables need to be dropped.
To remove base 650:
check the running DISKMUF where you want to remove this base. Note the STEPLIB Datacom/AD CUSLIB and CAAXLOAD data set names .
stop CA DISK and then run DBUTLTY with the correct STEPLIB data sets and SYSIN cards:
run DBSQLPR using that same STEPLIB to drop the tables. Have a look at Datacom/AD CAAXSAMP member AXIVP01 and prepare your JCL based on that member .
The cards in //SYSIN DD * should be
DROP TABLE CADISK.ARCHCMDS_650 ;
DROP TABLE CADISK.ARCHVOLS_650 ;
DROP TABLE CADISK.MIGRECAT_650 ;
DROP TABLE CADISK.DSNINDEX_650 ;
DROP TABLE CADISK.DASDSPCB_650 ;
DROP TABLE CADISK.DMSPARMS_650 ;
DROP TABLE CADISK.RETEXCLD_650 ;
DROP TABLE CADISK.DMSPOOLS_650 ;
DROP TABLE CADISK.RACFENCD_650 ;
DROP TABLE CADISK.RESTCMDS_650 ;
run DDUPDATE :
//DEL EXEC PGM=DDUPDATE,REGION=4096K
//STEPLIB DD DSN=your AD.CUSLIB,
// DD DSN=your AD.CAAXLOAD,
//SYSPRINT DD SYSOUT=*
//SYSOUT DD SYSOUT=*
//SYSPUNCH DD SYSOUT=*
//DDSNAP DD SYSOUT=*
//SNAPER DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//SYSIN DD *
run DBUTLTY (check again the STEPLIB) with SYSIN card
delete the physical data sets used by IXX650 and DMS650.
