More Help Required.. in Replication of Oracle 9i in Rh9 (if the query is repeated by me sorry)

hello,

Thanx for replying to my earlier Google group query about Replication
of Oracle 9i on RH9.IF the query followed is being repeated by me I am
sorry for it..

I want to implement replication by means of SQL commamnd prompt.Can u
help me with the sample script that you own.I can change the schema,
tables according to my need...Here is my situation of replication
requirement...

I have 3 systems with RH 9. A database of Oracle 9i is to be
replicated in the 3 pc.
I thought of Synchronous replication first where a change made once in
a database is updated immediately in all the rest. but the drawback is
that if 1 database server is down the update wont work ie it will
rollback.but it wont have any conflicst if all servers are up.

But, I dont want rollback situation. So I want to implement
Asynchronous replication which means that a change made will be stored
initally as deferred transaction (I think v can set time for updates
say for 2 seconds etc.ie; every 2 sec cache and database will be
updated...but i dont know the paramaeter to set)and later updated in
all database.I know in such case I know in that case i have to handle
conflicts (that the second phase). but wont check if all the database
servers are up.

Hope u have understood my need and would help me ...pls reply
regards,
