Second Data Center for Disaster Recovery

Discussion created by ca.portal.admin on Nov 5, 2009
Dear Listers :

We will be opening a new Disaster Recovery Center in less than a year.
We will be replicating all data to this center from our primary operations using an IBM product called
""Global Mirror"".

All data is replicated at the DASD block level in real time for all volumes.

The primary and secondary sites are not expected to be more than a minute or
two out-of-sync during the heaviest of processing.

All our archive journals are written to disk and then migrated off to tape
after several days.

Also, every day, we do a FLASHCOPY of the entire mainframe complex and do
nightly tape backups of the Flashed volumes.
This also captures all database, disk journals, and journal archives.

With all databases, journals, and even journal archives on disk...
and
In a true disaster, it seems that recovery is as simple as starting an instance of IDMS at the DR site and
let it go through WARMSTART.

Am I correct about this, or is it more complicated than that?
And if more complicated, I'll have the archives replicated if I have to do more.

Thanks.
Jon Gocher
