RLSE in ftp locsite

Postby crazydoc » Tue Jun 14, 2016 4:51 pm

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)
