Job Templates

[jseclen]

Hi,

In my Job Templates defined in Manager, in the AllocatedFile there is a line that calculate the BLOCKSIZE

// DCB=(LRECL=%reclen,BLKSIZE=%blocksize,RECFM=%recfm)

The real jcl in the 390 say

DCB=(LRECL=306,BLKSIZE=3060,RECFM=FB)

The DS is calculating the BlockSize = RecordLenght * 10 (records)

Can i to change the number of records to 100 ????

Hi,

Just to be precise, it's JCL templates you are refering to and JOB template which is a new DS feature in DS7. So you're title is a bit misleading.

It's in the project level .... You find it in the administrator under project properties --> Mainframe --> Max. blocking factor.

The default is 10 and you can change it.
BLKSIZE = Max. blocking factor * LRECL

In the projects I worked with we replaces the %blocksize variable in the JCL template to a constant zero like this:
// DCB=(LRECL=%reclen, BLKSIZE=0,RECFM=%recfm)

In this case the MF calculate the optimum...... anyway factor 10 is very small.
