I don't know your Oracle version, but if you can:
create snapshot xyz ON PREBUILT TABLE etc. ...
Then your Oracle version is OK.
There is more than one way to create the tables in the secondary database.
I usually create the empty tables, then for each table:
exec dbms_snapshot.refresh('TABLE_NAME','C')
set up the refresh group and refresh schedule (usually every five minutes
for me).
This certainly isn't the only way to do it.
I have never set up a failover site like this. I just do it this way
because we have so many frequent changes, that I do not want to completely
lose a snapshot table whenever I must temporarily drop a snapshot in order
to make some change. Sometimes in our test environment, we might want to
split a replication pair to run independently for a while. Then put
replication back in later.
