Use the following procedure to decompress z/OS software and reconstitute the install tape.

  1. Under USS/UNIX OS at the command prompt, enter the following command to obtain a checksum on each downloaded file: cksum <filename>
  2. Ensure the DCB attributes for the downloaded dataset on z/OS are: DSORG=PS,RECFM=FB,LRECL=1024,BLKSIZE=any legalmultiple of LRECL
  3. Decompress the file using the IBM TRSMAIN program. The following JCL can be used after it is customized:
    //TRSMN JOB
    //*
    //TRSMAIN EXEC PGM=TRSMAIN,PARM='UNPACK'
    //INFILE   DD DISP=SHR,DSN=<input.filename>
    //OUTFILE DD DISP=(,CATLG),DSN=<output.filename>,
    //	        UNIT=WORK,SPACE=(TRK,(10,500,5),RLSE)
    //SYSPRINT DD SYSOUT=*
    //
    
  4. Customize the JOB and PROC statements in member EDRECV of the OUTFILE dataset.
  5. Submit the JOB. A tape is created that can be installed according to the standard installation instructions.
