Does anyone have any information, experience, or resources related to using rsync to replicate data volumes on an Oracle database? Related to this, any (FOSS or not) HA applications?
Here's the scenario:
I work at Mohegan Sun Casino, and we're installing a system which uses an Oracle back-end database on SuSE Linux Enterprise Server 8. We are a 24x7x365.25 operation-- i.e. we never close. Because of that, we will have two complete systems in two separate buildings about one half mile apart, and connected by a gigabit fiber connection. In the event of any kind of failure on box "foo", we want box "bar" to take over functionality within milliseconds and be as up-to-date as practical.
I intend to use rsync to keep the OS and binary portions in sync, but I'm not sure the overhead will play well with the database operation. For the record, I am currently looking at SteelEye as a possible software solution and EMC as a possible hardware solution. Any others?
Thanks!
