Good day. In the distribution sets in one of the ask me, use the parameters:
SPACE=(TRK,(65000,15000),RLSE)
. Is it possible to describe something like that when you receive a file via FTP?

Hello,
Afaik, in a mainframe environment, whenever a dataset is to be referred, there is always a mechanism in place which allows a user to tweak the DCB/SPACE parameters.
Couple of thoughts for your query:
a. Have a step in the FTP JCL which defines the dataset in which you want to receive the data; the definition parameters will be governed by JCL rules, hence RLSE will be allowed here.
b. Look at the SEZAINST definitions, you'll be having a member (for eg: EZAFTPAS) which has the default priming parameters defined; though before you do this - highly recommend that you check with your site admin, as these parameters are usually customized site-to-site; and some people might not feel happy with you tweaking a parameter in this PDS.
Hope this helps.

Just a bit of a warning. The JCL RLSE parameter in SPACE=(...,RLSE) or its equivalent in dynamic allocation does not work the way many people think. RLSE is
not a data set attribute. In this JCL no space is released.
//A EXEC PGM=IEFBR14
//NEWDS DD DISP=(,PASS),UNIT=SYSDA,SPACE=(TRK,(50,10,5),RLSE),
// DCB=(RECFM=FB,LRECL=80),DSN=&SYSUID..SRC
//B EXEC PGM=IEBDPDTE,PARM=NEW
//SYSPRINT DD SYSOUT=*
//SYSUT2 DD DISP=(OLD,CATLG),DSN=*.A.NEWDS
//SYSIN DD *
./ ADD NAME=IEFBR14
IEFBR14 RSECT
IEFBR14 AMODE 31
IEFBR14 RMODE ANY
SR 15,15
BR 14
END IEFBR14
However, space is released in this JCL.
//A EXEC PGM=IEFBR14
//NEWDS DD DISP=(,PASS),UNIT=SYSDA,SPACE=(TRK,(50,10,5)),
// DCB=(RECFM=FB,LRECL=80),DSN=&SYSUID..SRC
//B EXEC PGM=IEBDPDTE,PARM=NEW
//SYSPRINT DD SYSOUT=*
//SYSUT2 DD DISP=(OLD,CATLG),SPACE=(TRK,1,RLSE),
// DSN=*.A.NEWDS
//SYSIN DD *
./ ADD NAME=IEFBR14
IEFBR14 RSECT
IEFBR14 AMODE 31
IEFBR14 RMODE ANY
SR 15,15
BR 14
END IEFBR14

Thanks for the help. In the end, it was decided not to allocate the exact space under taken a dump(was assigned 27gb drive and distributed all of it, even if you take a dump less)
