Getting 2 databases in sync via ASymmetric Replication
Posted on 2003-02-24
I have configured asymmetric replication between 2 Oracle databases(8i).
If 1 database goes down, I intend to get it in sync with the other database when it comes up by using the DBMS_DEFER_SYS.PUSH procedure.My understanding from a thread I had run before in Experts-exchange was that the data in the deffered transaction queue is stored in the system tablespace and hence when I run this procedure the data will be "pushed" to the second database.I have also tried it and the concept I believe is right
THe Q is this:
If the database is down for a long period of time, the replication job will fail after 16 attempts.Does this mean that the data will no longer be put in the Deferred Q.Hence when I run the DBMS_DEFER_SYS.PUSH..I will not get all the data but only the data for the first 16 job attmpts..Is that a valid statement
