Procedure for Installing TRSMAIN from
the IBM FTP site
TRSMAIN utility is used to compact documentation prior to
FTP'ing it to IBM.Using the TRSMAIN to compress data will save time when you
are sending and receiving files. TRSMAIN can also be used to uncompress files
that have been compressed or packed. If you have not installed the TRSMAIN
program on your local OS/390 system, you can obtain a copy of the TRSMAIN
program using the FTP instructions below.
ftp://ftp.software.ibm.com/s390/mvs/tools/packlib/README.HTML
1.) FTP instructions for downloading
the TRSMAIN program from the IBM FTP site.
FTP ftp.software.ibm.com
FTP to the host name ftp.software.ibm.com USER: anonymous login as
anonymous user with e-mail password PASSWORD: your complete e-mail address
CD s390/mvs/tools/packlib go to the directory containing TRSMAIN BIN
to set up binary mode transmission LOCSITE RECFM=FB LRECL=80
BLKSIZE=3120 GET TRSMAIN dtrsmain download
TRSMAIN into a file called dtrsmain quit get back into your TSO
session
Note: We called the TRSMAIN we downloaded using the get
command as
dtrsmain, (for downloaded trsmain)
but this file can be any name.
2.) Once the TRSMAIN program has been
downloaded we must allocate a PDS (i.e. PACKLIB )
file with
the following characteristics: We will call this PDS file PACKLIB
Volume serial . . . .
Generic unit. . . . .
Space units . . . . . BLOCK
Primary quantity. . . 24
Secondary quantity. . 3
Directory blocks. . . 1
Record format . . . . U
Record length . . . . 0
Block size . . . . . 13030
Expiration date . . .
3.) Issue TSO RECEIVE INDSN(dtrsmain)
from your TSO session to convert the
TRSMAIN program that we downloaded above into a load module format.
The following messages will be displayed after the above command.
INMR901I Dataset PTFLCG.TERSE409.LOADLIB from NHAN on PLPSC
INMR902I Members: TRSMAIN
INMR906A Enter restore parameters or 'DELETE' or 'END' +
you should reply to INMR906A with the PDS name, which you allocated
earlier, and member name - TRSMAIN.
(i.e. DA( PACKLIB(TRSMAIN))
4) Once the PACKLIB is created , use
the following sample JCL to create your own job
to compress/pack any file
using TRSMAIN.
Here is the sample JCL to compress &input_dataset into its
COMPRESSED format.
//PACKIT JOB 'ACCOUNTING INFORMATION',NOTIFY=&SYSUID.
//****************************************************
//* *
//* TRSMAIN with PACK option *
//* *
//****************************************************
//JOBLIB DD DISP=SHR,DSN= &PACKLIB
//STEP EXEC
PGM=TRSMAIN,PARM=PACK
//SYSPRINT DD SYSOUT=H
//INFILE DD
DISP=SHR,DSN=&input_dataset
//OUTFILE DD
DISP=(NEW,CATLG),UNIT=SYSDAL,
// DSN=&output_dataset,
// SPACE=(CYL,(ppp,sss),RLSE)
The JOBLIB DD can be eliminated if the &PACKLIB is
included in the LNKLST concatenation.
The &input_dataset in the
INFILE DD must be modified with the proper dataset name that needs
to be
compacted with the TRSMAIN utility.
The &output_dataset in the
OUTFILE DD must be modified with the proper dataset
name that will contain
the new packed/compressed file from the TRSMAIN utility.
The ppp and sss is the primary and secondary space for the
output dataset
Once the JOB gets executed successfully, you should use the
&packed_output in your FTP output process.
When you FTP this COMPRESSED dataset to the IBM Support
center, please name that dataset that you just
packed/compressed with PACKED
as the last qualifier, so IBM support personal knows to
UNPACK/uncompress
this dataset after it is obtained.
5) Use the following sample JCL to
create your own job
to unpack or decompress a file using TRSMAIN.
Here is the sample JCL to uncompress &input_dataset into its
UNCOMPRESSED format.
//UNPACKIT JOB 'ACCOUNTING INFORMATION',NOTIFY=&SYSUID.
//****************************************************
//* *
//* TRSMAIN with UNPACK option *
//* *
//****************************************************
//JOBLIB DD DISP=SHR,DSN= &PACKLIB
//STEP EXEC
PGM=TRSMAIN,PARM=UNPACK
//SYSPRINT DD SYSOUT=H //INFILE DD
DISP=SHR,DSN=&input_dataset
//OUTFILE DD
DISP=(NEW,CATLG),UNIT=SYSDAL,
// DSN=&output_dataset,
// SPACE=(CYL,(ppp,sss),RLSE)
The JOBLIB DD can be eliminated if the &PACKLIB is included in the LNKLST concatenation.
The &input_dataset in the
INFILE DD must be modified with the proper dataset name that needs
to be
uncompacted with the TRSMAIN utility.
The &output_dataset in the
OUTFILE DD must be modified with the proper dataset
name that will contain
the unpacked/uncompressed file from the TRSMAIN utility.
The ppp and sss is the primary and secondary space for the
output dataset
