You can make a backup of a VSAM to a sequential GDG though. To create a new gen you should be using PROD.CVSC.AHI.BKP(+1) -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Frank Swarbrick Sent: Tuesday, September 26, 2023 12:27 PM To: [email protected] Subject: [External] : VSAM GDG Are VSAM GDGs supported? I created the GDG base using the JCL below and was able to create the first generation, but when I run that job again it tries to create generation 1 again, giving me a JCL error because the GDS already exists. //DEFGDG JOB ,'DEFINE AHI GDG //DEFINE EXEC PGM=IDCAMS //SYSPRINT DD SYSOUT=* //SYSIN DD * DELETE (PROD.CVSC.AHI.BKP) IF MAXCC LE 8 THEN SET MAXCC=0 DEFINE GDG ( - NAME(PROD.CVSC.AHI.BKP) - LIMIT(5) - SCRATCH - ) Thanks, Frank ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
