Hi Prem
I was reading some of the other replies and you have said strictly 0% data
loss for committed transactions, well any standard Oracle installation
will do that, If you want 0% downtime then you can only do that with RAC,
but that depends on your application design and technology. Any other
failover HA solution has possibly a small downtime window, minutes or
seconds to drop and reconnect users to the alternate instance and may roll
back some transactions, but these are uncommitted so you are safe there
So for a better design of your maybe HA solution you might need to better
define your requirements
Cheers

0% data loss setup ?
Hi List,
We will be soon having a system and it requires
strictly 0% data loss in any case . Not even a
single commited transaction should be lost.
The setup will be 9iR2 on win2k .
Standby database (max protection mode) may be a
choice.But the primary DB tends to go down if it
is not able to communicate with standby DB.this
reduces the availability of my primary DB and so
is not my option.And standby database in ( max
availability mode) can have data loss and hence
is ruled out.
any HA suggestion ?!
can someone let me know how it can be acheived ?
Regards,
Prem.
