Home -> Community -> Mailing Lists -> Oracle-L -> Re: best hot standby solution
You can use two database replicated and use load balancing and failover on
SQL*Net configuration.
When one database is down the connection from the web is going to the up database.
The bad part is when you put the database up you need to reboot the web server (Oracle Application Server).
There are some downtime for replication configuration (for insert/update/delete) when the replication group is suspended. This time can be short if you create many replication groups for different table based on the application logic.
