The following are the different applications of IDCAMS utility in mainframe. This is applicable for both VSAM and non-VSAM datasets.
ALTER – The Alter modifies a catalog, alternative index, cluster and path.
Example to use ALTER
//ALTERE EXEC PGM=IDCAMS,REGION=4M //SYSPRINT DD SYSOUT=A //SYSIN DD * ALTER CICS.* - NEWNAME(CICSA.*) /*
BLDINDEX– builds alternate index.
Example to use BLDINDEX
//BUILDX1 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSOUT DD SYSOUT=*
//SORTWK01 DD SPACE=(CYL,(50,50))
//SORTWK02 DD SPACE=(CYL,(50,50))
//SYSIN DD * BLDINDEX IDS(VSAMAIX.BIX.ESDS) ODS(VSAMAIX.BIX.AIX) SORTMESSAGELEVEL(ALL)
/*
DEFINE– for alternate index, cluster or path.
Example to define ALTINDEX
//DEFAIX1 JOB ...
//STEP1 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=A
//SYSIN DD *
DEFINE ALTERNATEINDEX -
(NAME(EXAMPLE.AIX) -
RELATE(EXAMPLE.KSDS2) -
KEYS(3 0) -
RECORDSIZE(40 50) -
VOLUMES(VSER01) -
CYLINDERS(3 1) -
NONUNIQUEKEY -
UPGRADE) -
CATALOG(USERCAT)
/*
LISTCAT – lists information about dataset. LISTCAT to list the aliases associated with a catalog.
//LSTALIAS EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=A
//SYSIN DD *
LISTCAT ALL ENTRIES(SYS1.ICFCAT.VSYS303)
/*
PRINT- prints contents.
REPRO– copies records from one dataset to other dataset.
DELETE– removes catalog entry for catalog, cluster, alternate index, or path.
Example for PRINT, REPRO and DELETE
//SYSIN DD *
DEF CL(NAME(VSAMAIX.BIX.ESDS) TRACKS(10 5) RECSZ(8 8) NIXD NRUS)
IF MAXCC > 0 THEN CANCEL ;
REPRO IDS(VSAMAIX.BIX.FLAT) ODS(VSAMAIX.BIX.ESDS)
IF MAXCC > 0 THEN CANCEL ;
DEF AIX(NAME(VSAMAIX.BIX.AIX) REL(VSAMAIX.BIX.ESDS) -
RECSZ(4086 240000) KEYS(3 4) TRACKS(5 5) NUNQK)
IF MAXCC > 0 THEN CANCEL ;
BLDINDEX IDS(VSAMAIX.BIX.ESDS) ODS(VSAMAIX.BIX.AIX) NOSORTCALL
IF MAXCC > 4 THEN CANCEL ;
LISTC ENT(VSAMAIX.BIX.ESDS VSAMAIX.BIX.AIX ) ALL PRINT IDS(VSAMAIX.BIX.ESDS)
DUMP COUNT(20)
PRINT IDS(VSAMAIX.BIX.AIX)
DUMP
DELETE VSAMAIX.BIX.*
