DDC file 1-way replication example:

The following DDC file settings shows an example of a 1-way replication process.
The source server is on Linux server:               rac11202node1
The target is on Linux server:                          dbvisit400
The TNS names for the source database is:     orcl
The TNS names for the target database is:      test11202
There is no FETCHER process.

DDC DB

The DDC DB is as follows (orcl-onetime.ddc):

####################################################################################
This file is used only during the setup, then it's contents is loaded as DDC DB into mine database

load ddcdb

memory_set ON_ERROR SKIP

Memory_set command will set the value in APPLY memory and not in the actual metadata. Therefore you see the default value in console as it reads the metadata and not the APPLY memory

The use of the following processes to enable 2-way replication:

  • MINE – default MINE process on the first server.
  • MINE2 – Second MINE process to MINE on the second server.
  • APPLY – default APPLY process to APPLY on the second server.
  • APPLY2 – Second APPLY process to APPLY on the first server.
