Session 25- 7
Comm-Press v4.4 Difference between v3.0.1 & v4.4 Helpful hints for compression and decompression Distribution timeline Minimum platform requirements
![Page 8: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/8.jpg)
Session 25- 8
Difference Between v3.0.1 & v4.4?
State-of-the-art data compression techniques to
reduce the size of data files by as much as 95%
Enhanced DECOMP feature to write partial or
corrupt files to DATAXX file
USEREXIT is replaced with SECFILE
![Page 9: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/9.jpg)
Session 25- 9
COMPRESS Difference Running v3.0.1: //COMP301 EXEC PGM=COMPRESS, // PARM='UXIT=COMPEXIT,ASCII,CRLF'
Running v4.4: //COMP44 EXEC PGM=COMPRESS, // PARM='ASCII CRLF SECFILE=DD:SECFILE'
![Page 10: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/10.jpg)
Session 25-10
COMPRESS Helpful Hints
When executing COMPRESS the parameters of ASCII, CRLF and SECFILE are required
– PARM='ASCII CRLF SECFILE=DD:SECFILE’
ASCII - Causes COMPRESS to translate the data to ASCII or EBCDIC, if necessary, depending on the platform where the data is decompressed
![Page 11: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/11.jpg)
Session 25-11
COMPRESS Helpful Hints
CRLF - Causes COMPRESS to convert delimiter characters (for example, line feeds or carriage return/line feed pairs) into record separators
SECFILE - Replaces USEREXIT and causes COMPRESS to recognize header/trailer:
HEADERLITERAL(O*N05) HEADERSTART(1);
TRAILERLITERAL(O*N95) TRAILERSTART(1);
LITERAL(O*N01) LITERALSTART(1);
LITERAL(O*N99) LITERALSTART(1);
![Page 12: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/12.jpg)
Session 25-12
COMPRESS Helpful Hints
Using the DD statement COMPLOG, defined as RECL=121,RECFM=FB,will provide additional information regarding the compression of the data
![Page 13: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/13.jpg)
Session 25-13
DECOMP Difference Running v3.0.1: //DCOMP301 EXEC PGM=DECOMP
Running v4.4: //DCOMP44 EXEC PGM=COMPRESS, // PARM=’SAFE CRLF UNCOMP SECFILE=DD:SECFILE'
![Page 14: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/14.jpg)
Session 25-14
DECOMP Helpful Hints
When executing DECOMP the parameters of SAFE CRLF UNCOMP and SECFILE are required
– PARM=’SAFE CRLF UNCOMP SECFILE=DD:SECFILE’
SAFE - This option causes DECOMP to create a
reject file (DATAXX) containing data that fails
decompression. Only valid data is written to the
output file(s)
![Page 15: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/15.jpg)
Session 25-15
DECOMP Helpful Hints CRLF - During decompression, the delimiter
characters that are appropriate for the target platform replace the record separators
UNCOMP - This option signals DECOMP that the input files contain valid uncompressed data in addition to compressed data. DECOMP will copy the uncompressed data to the output files as it decompresses
![Page 16: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/16.jpg)
Session 25-16
DECOMP Helpful Hints SECFILE - Replaces USEREXIT and causes
DECOMP to recognize header/trailer:
HEADERLITERAL(O*N05) HEADERSTART(1);
TRAILERLITERAL(O*N95) TRAILERSTART(1);
LITERAL(O*N01) LITERALSTART(1); LITERAL(O*N99) LITERALSTART(1);
Partial files will be written, uncompressed, to the DATAXX file and not the DATAOT file with an invalid return code of 69
![Page 17: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/17.jpg)

Session 25-33
A Closer Look At “Non-PC” Users
Current ‘RECEIVE’ takes three steps:
1.BPARSER:– Connect– Receive– Disconnect
2.ONVTAM62 (Open*Net Communication)3.Decompress
![Page 34: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/34.jpg)
Session 25-34
A Closer Look At “Non-PC” Users
Proposed ‘RECEIVE’ takes one step:
1.PGM=EA2KMVSC, PARM=‘CMDFILE’
– The CMDFILE contains the RECEIVE command-line to be executed
– In one step, the EA2KMVS PGM will:• Connect
• Receive & Decompress
• Disconnect
![Page 35: Session 25-](https://reader035.fdocuments.net/reader035/viewer/2022081603/568143d5550346895db061e0/html5/thumbnails/35.jpg)
