Using ARCINBAK allows applications to take point in time backups meaningful to the application as opposed to during a predetermined backup window. Having the backup under HSM control allows you to select the backup you want to restore from the output of a HLIST command as opposed to guessing which DFDSS GDG to restore.
What is the priority for HSM? It should be above batch workloads but below any onlines such as TSO, CICS, IMS and DB2. To throttle back HSM CPU you might set Intervalmigration to NOINTERVALMIGRATION. Or just run one or two Intervals a day, preferably not at peak times. The only time HSM CPU is noticed around here is if I allow too many concurrent recalls to take place. How many are you allowing? -----Original Message----- From: Ambat Ravi Nair [mailto:[EMAIL PROTECTED] Sent: Thursday, March 15, 2007 9:36 AM To: [email protected] Subject: ARCINBAK or DFDSS - what's the advantage ? we have applications that make use of ARCINBAK to backup datasets during their Batch runs (which goes to tape). i often wondered what benefit that gives, when compared to DFDSS. what scenarios will prove beneficial to use ARCINBAK ? as it is, we have a tough time justifying the CPU usage for DFHSM .... many thanks! - ravi. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
