RE: Disaster Recovery: Oracle Data Guard or Storage Snapshots?

Thanks for catching this Niall. You are correct! In the past we could activate the database in the DR SAN store as a "failover" environment, maximum duration is 10 days/calendar year (not 15 as I specified), as long as production is also taken down at the same time.

I went back and looked at the version I had (dated Mar 2009), following is the verbiage I see: (nothing about the shared storage)

"If the primary node fails, one of the nodes in the cluster acts as the
primary node. In this type of environment, Oracle permits licensed Oracle Database customers to run the Database on an unlicensed spare computer for up to a total of ten separate days in any given calendar year."

From the document you sent (Apr 2010):
"In this type of environment, Oracle permits its licensed Technology customers to run the Technology Programs (listed on the Technology Price List) on an unlicensed spare computer for up to a total of ten separate days in any given calendar year. The above right only applies when a number of machines are arranged in a cluster and share one disk array."
Oracle seems to have added the "shared disk" verbiage to close the loop-hole.

Thanks

If you go with Data guard you need to have Oracle Enterprise Edition (hope you already know this..) and your data guard site should also be licensed similar to production with all the Enterprise Edition options. If you use SAN based replication you may be able avoid purchasing the Oracle licenses as long as you use your data guard site <15 days in a year. Oracle keeps changing these policies, you may want to review the current licensing document if you choose this approach.

That's not my reading of the current policy! http://www.oracle.com/us/corporate/pricing/data-recovery-licensing-070587.pdf
