Replication software
i recently ordered Sun serevrs for my network and i will be using Solaris 10.
i want to replicate my DB, i am looking for a good replicattion software for Host---Host replication ( i dont want cluster), any sugegstion would be great Help.

Sun ST H/A solution is very expensive + Complicated + Difficult to manage.
i was planning Veritas but still not yet finalize, so you know any other ???
you should consider Veritas Syorage Foundation and Volume Replicator ( as you mention you are having Sun Storage in your other question "Server Hardware")
Veritas solution will be cheap, 24x7 support, but still the solution will be complicated. i am not sure but i think Veritas will have GUI interface for Solaris.
may i know what type of relication you are planning, i mean Volume Base? Bit Levevl? Block Level?, have you consider bandwidth issues as well???

i just spoke to my Sun vendor he is saying the solution will be very expensive and i may need to buy license base on per processor, which will be very expensive (8 cores) in my case as I am planning to use replication software for my application.
i dont know what type of replication i should go for, H/A site will be connected VIA Fiber.
Is asynchronous replication good enough ? If yes, have a look at the Solaris ZFS filesystem. It allows snapshotting and volume replication (block based).
If you do some clever scripting, you can create database consistent snapshots that can be replicated to the other machine.

i am not using Oracle ad DB, my DB will be jbase.

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
