Issue/Introduction

How do we disable the compress function of  Compress in a specific job step?

Environment

Release: 5.5

Component: Compress for z/OS

Resolution

Use exclude statement in the job step to be excluding Compression functions    

                         

 //@ZSM@XFR DD DUMMY     

CA Compress supports exclusion by user-specified ddname, in one of two formats.

To invoke exclusion for all compressed data sets in the step, specify:

//@ZSM@XCL DD DUMMY

To specify exclusion of specific ddnames, specify them in the nodes of the DSN as follows. You can exclude as many ddnames as you can fit in the 44-byte DSN:

//@ZSM@XCL DD UNIT=SYSALLDA,SPACE=(TRK,0),DSN=hlq.ddn1.ddn2

For example, to exclude ddnames SYSUT1 and SYSUT2, where MYTSOID is a valid high level qualifier:

//@ZSM@XCL DD UNIT=SYSALLDA,SPACE=(TRK,0),

// DSN=MYTSOID.SYSUT1.SYSUT2
