IDCAMS stands for Integrated Data Cluster Access Method Services. IDCAMS utility is used to create, modify and delete the VSAM datasets.
IDCAMS Utility is very useful utility to manipulate VSAM datasets
A typical example of a simple use of IDCAMS is as follows:
Example 1: Allocating and Loading Data Into VSAM
//JOBIBMKS JOB (123),'IBMMAINFRAMER',CLASS=C,MSGCLASS=S,MSGLEVEL=(1,1),
// NOTIFY=&SYSUID
//*
//STEP001 EXEC PGM=IDCAMS
//SYSPRINT DD *
//DATAIN DD DISP=OLD,DSN=userid.TEST.INPUT
//SYSIN DD *
DEFINE CLUSTER (
NAME (userid.TEST.VSAM) -
VOLUMES(WORK02) -
CYLINDERS(1 1) -
RECORDSIZE(72 100) -
KEYS(9 8) -
INDEXED)
REPRO INFILE(DATAIN) -
OUTDATASET(userid.DATA.VSAM) -
ELIMIT(200)

Example 2: Deleting a VSAM dataset
//JOBIBMKS JOB (123),'IBMMAINFRAMER',CLASS=C,MSGCLASS=S,MSGLEVEL=(1,1), // NOTIFY=&SYSUID //* //STEP001 EXEC PGM=IDCAMS //SYSPRINT DD SYSOUT=* //SYSIN DD * DELETE useird.DATA.VSAM CLUSTER /* |
