TSO command to comprime

Hi,
I am having storage problems with a dataset. I am not remembering the tos command to comprime a dataset space.

Please help.

Thanks in advance,
Jordi

What do you mean by comprime ? (My dictionary returned nothing...)

If you want to COMPRESS a data set, here are the 2 most common methods:

1) Use IEBCOPY to copy the PDS to itself.
2) Use ISPF option Z against the PDS from 3.4 screen.

ANS : USING JCL

//H49COMPR JOB 'TEST','COMPRESS',CLASS=2,MSGCLASS=W,
//NOTIFY=&SYSUID,
//STEP001 EXEC PGM=IEBCOPY
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD DSN=H49$.SYNTEL.CDM.WORK,DISP=SHR
//SYSIN DD *
COPY INDD=SYSUT1,OUTDD=SYSUT1
/*

ANS: USING TSO COMMAND

STEP 1: TYPE Z BEFORE THE DATASET NAME IN 3.4 OPTION

u can type "RLSE" for the removing of unused space aganist the dataset in 3.4 option.

There is no RLSE line command in ISPF 3.4. It's probably some local program. You can see all the valid ISPF 3.4 line commands in the fine manual.

RLSE is coded in JCL. The equivalent ISPF command is Free, just issue F against the dataset.

But this does not compress a dataset, this simply frees the unused space.

try once in ur mainframes sesion against any one of the dataset

Try what? RLSE does not work in 3.4, well at least in my shop.

hy,

then RLSE is probably self-written, but this does not matter...

pls note: if there is an enqueue on your dataset,
the only chance to compress a pds, is to use iebcopy
on itself (i.e. inputfile and outputfile is the same).
if you have a pds/e you cannot compress. you must
allocate a new one and copy all the members into it!

if after compress, the problem still exists, you must allocate
a new dataset with gretaer space amount and copy all members into it.
don't forget the necessary directory blocks.

hi ,

Z doesn't work when the dataset in use only the IEBCOPY works always because for dataset you will give DISP=shr...
