Logical standby is available from 9i onwards. I would either go with MV
or Logical standby if I could. Advanced Replication is a night mare to
administer and is to be avoided unless you want 2 ways replication,
which is indeed very complicated in the first place.

Thanks Mark and Jared.
   
  I should have specified that we are not on 10G so logical standby is
not 
really an option. So I am looking at MV or advanced replication. Thanks
 
    Hi,
     I have a 250 GB database and need to replicate it with almost all
the 
tables. I am thinking of doing MV replication. Other option is advanced 
replication. What are pros and cons of using MV as opposed to advanced 
replication. I think some of the maintenance to be done is less in case
of MVs 
and it is simpler to understand and setup. Any advantages for advanced 
replication? What about data integrity on target. I think advanced
replication 
checks before applying changes so any loss of transaction is detected.
Is there 
any check in case of MV? Any tools to check the data on target?  I think
the 
performance impact degradation on source for both is almost same.  
  Thanks for your help.

the amount of time required to complete each row-level DML statement
gets longer as time goes on. My previous, quite-lengthy thread goes
into the gory details. Won't add to that thread until I get final
resolution from Oracle Support.
