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