I need to keep two databases in Sync over a network.
For eg. if a object in one Database gets updated the object in the other DB should get updated instantly. what are the various options available of doing the same? and where can I find more information about them?
Please enlighten.

If you are using Enterprise Edition you may consider Oracle's Advanced Replication. Here is a link to a tech note I have written which can provide some ideas to consider when planning Advanced Replication:

Here are some scripts which could be helpful to you when setting up replication:

One of the critical aspects of replication which is handled by these scripts is the implementation of a robust method of conflict resolution.

Another method to consider is creating a Standby database - which should be done if upon looking at the above tech note you determine that Replication is not appropriate for your installation.
The following list of scripts provides an example of how you can set up a standby database (start with script #77 on this page):
