Oracle GoldenGate Best Practice
Oracle GoldenGate sample parameter files
Objective: This paper provides sample example of Oracle GoldenGate parameter files that can be used to configure Oracle GoldenGate replication setup inline with recommended best practices. The example is generic and can serve as a starting point for a more customized Oracle GoldenGate implementation
Process name: Manager
Description: Manager is GoldenGate's parent process and is responsible for the management of GoldenGate processes, resources, user interface, and the reporting of thresholds and errors.
Manager parameter file (Sample)
-- Manager port number
-- As a Manager parameter, PURGEOLDEXTRACTS allows to manage trail
-- files in a centralized fashion and take into account multiple
PURGEOLDEXTRACTS , USECHECKPOINTS, MINKEEPHOURS <"x" hours> MINKEEPFILES <"y" number of files>
-- Start one or more Extract and Replicat processes automatically after -- they fail. AUTORESTART provides fault tolerance when something
-- temporary interferes with a process, such as intermittent network
-- outages or programs that interrupt access to transaction logs.
--This is to specify a lag threshold that is considered critical,
--and to force a warning message to the error log. Lagreport parameter
--specifies the interval at which manager checks for extract / replicat --lag.
Process name: Extract
Description: The Extract process captures either full data records or transactional data changes, depending on configuration parameters, and then sends the data to a target system to be applied to target tables or processed further by another process, such as a load utility.
--DBLOGREADER enables Extract to use a read buffer size of up to 4 MB --- in size. A larger buffer may improve the performance of Extract when -- redo rate is high.The db has to be 10.2.0.5 or higher to use
-- this feature. If DBLOGREADER parameter is in place then the above
