Use the following procedure to decompress z/OS software and reconstitute the install tape.
- Under USS/UNIX OS at the command prompt, enter the following command to obtain a checksum on each downloaded file: cksum <filename>
- Ensure the DCB attributes for the downloaded dataset on z/OS are: DSORG=PS,RECFM=FB,LRECL=1024,BLKSIZE=any legalmultiple of LRECL
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=* //
- Customize the JOB and PROC statements in member EDRECV of the OUTFILE dataset.
- Submit the JOB. A tape is created that can be installed according to the standard installation instructions.
