DYNUTIL - Restore Files from DYNUTIL Back-Up Tapes

DYNUTIL is an MVS utility program which processes back-up tapes created in VSE by the DYNAM/D utility DYNUTIL. Using DYNUTIL, an OS/390 or z/OS installation can restore SAM or DAM files from a DYNUTIL tape, or list the files it contains.

DYNUTIL was initially designed for VSE sites which convert to MVS and have a significant number of archive tapes in DYNUTIL format, which they may have to restore after the end of their migration, when they no longer have access to a VSE system. DYNUTIL can also be used during the course of a VSE/MVS conversion to facilitate the transfer of VSE application data to MVS.

DYNUTIL restores SAM or DAM files into pre-allocated data sets only.

Sample JCL (LIST)

List the files contained on a DYNUTIL back-up tape.

//LIST     EXEC PGM=DYNUTIL,PARM=(LIST,TAPEIN)
//STEPLIB   DD DSN=SYS2.DYNUTIL.LOAD,DISP=SHR
//SYSPRINT  DD SYSOUT=*
//*
//TAPEIN    DD VOL=SER=999999,UNIT=CART,DSN='CT99.SET.1' 

Sample JCL (RESTORE)

Restore/Rename two files from a DYNUTIL back-up tape, stop processing if any error is encountered.

//RESTORE  EXEC PGM=DYNUTIL,PARM='RESTORE,TAPEIN,STOP'
//STEPLIB   DD DSN=SYS2.DYNUTIL.LOAD,DISP=SHR
//SYSPRINT  DD SYSOUT=*
//*
//TAPEIN    DD VOL=SER=999999,UNIT=CART,DSN='CT99.SET.1'
//*
//SYSIN     DD *
