There are two main methods in which the Oracle Extractor can be configured, Review Section 5.2.1, “Understanding Deployment Models” for full details of the differences between each deployment style, and then follow the relevant section below for the correct steps to install the Oracle Redo Reader extractor based on your installation needs.
This method will involve both the Oracle Redo Reader and the Tungsten Replicator being installed on the same host as the Oracle Database Server.
The Redo Reader will run the
FETCHER process will not
This method will involve the Oracle Redo Reader still being installed on the local Oracle Database Server, but the Tungsten Replicator being installed on a different host, referred to as the offboard Host.
This method would be typically used in the following situations:
Oracle Database Server OS is not supported by Tungsten Replicator
Unable to fulfill prerequisite requirements for Tungsten Replicator, such as installation of Ruby, Java etc
Customer restriction on the installation of software on the DB Hosts
The offboard installation method can be achieved with three different configurations:
Offboard with FETCHER
Offboard with NFS
Offboard with Archive Log Shipping
Each process follows the same basic installation, with a few various configuration differences made during deployment.
The offboard host will run the
MINE process and the
Tungsten Replicator extractor
Depending upon the configuration above will determine the configuration required on the DB Host.
This method specifically outlines the steps for topologies where the source database is Oracle RAC.
The deployment model follows the concepts of the offbard with FETCHER method, with specific configuration requirements for the RAC hosts
