Re: MVS mirrored DB & logs

I dropped the DB mirror when I moved the DB from 3380-k to an Iceberg. I
am still mirroring the log. This is what IBM recommends in the the ADSM
Admin guide when using mainframe raid dasd.
I am saving 6 3390-3 images by not having DB mirrors. There is no doubt a
savings in cpu time and channel busy, but I haven't measured those things.

Since my DB and recovery logs are on raid devices, I'm thinking about
shutting off the mirroring of those dsn's. Has anyone done this and what
were the resources savings as a result??
