Recently getting module too large to process messages and notice that if the block size of the master file is increased these messages are eliminated.
What is the easiest way to increase the blocksize of Librarian Master files?
Release: 4.4
1. Using the sample JCL below the master file is backed up to a temporary master file with the new block size specified in the DCB parameter.
//S1 EXEC PGM=AFOLIBR,PARM='NRJS,NJTA'
//SYSPRINT DD SYSOUT=*
//OSJOB DD DUMMY
//LIST DD SYSOUT=*
//INDEX DD SYSOUT=*
//MASTER DD DSN=your.master.file,DISP=SHR
//BACKUP DD DSN=your.temp.master,DISP=(,CATLG),
// DCB=(BLKSIZE=nnnnn,DSORG=DA),
// SPACE=(CYL,(nnn)),VOL=SER=nnnnnn,UNIT=SYSDA
//SYSIN DD *
-OPT BKUPDISK,INDEX

2. Rename the original master file in ISPF to .OLD
3. Rename the temporary master file to the original name.
