1) Increase the number of buffers on OUTDD1 2) Investigate the Large Blocksize Interface (LBI) 3) opt(4) On the dump command
The real question is what is the limiting factor, TAPE or DISK? Items 1 and 2 address the TAPE side Item 3 addresses the DISK side -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Nai, Dean Sent: Wednesday, October 16, 2019 10:31 AM To: [email protected] Subject: DSS Hi, I'm just reaching here because it's probably a hardware limitation but I'll ask anyway. Our current backup solution is to flashcopy our volumes and then go back and dump them to tape using DSS. Now we started backing up some of the huge E3 volumes and it's been taking 50 minutes per volume. I was wondering if there have been any changes in DSS parameters that might save us time. These are the parameters we are still using: DUMP - ADMIN - INDDNAME(INDD1) OUTDDNAME(OUTDD1) - CPVOLUME - TRACKS(0,0,322769,14) Dean Nai > ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ::DISCLAIMER:: ________________________________ The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
