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 PORT -- As a Manager parameter, PURGEOLDEXTRACTS allows to manage trail -- files in a centralized fashion and take into account multiple -- processes. PURGEOLDEXTRACTS , USECHECKPOINTS, MINKEEPHOURS MINKEEPFILES ----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.

AUTORESTART EXTRACT *, RETRIES , WAITMINUTES , RESETMINUTES --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. LAGREPORTMINUTES LAGCRITICALMINUTES

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.
