  GoldenGate Architecture tips

Oracle Database Tips by Donald BurlesonApril 1, 2015

GoldenGate Architecture

The Oracle GoldenGate instance is composed of Oracle GoldenGate software location and an associated manager process. Figure 1-13 depicts Oracle GoldenGate architecture on bi-directional environment.
·         The manager process, running on the source and target systems for handling events and starting dynamic extract and replicate processes. It also performs trail file purge management for maintaining an optimized disk utilization.
·         The primary extract is referred to as the change data capture (CDC) process, and it reads the transaction logs and write to either a local trail or send data directly to the data sever collector of the remote system (depending weather a data pump is used or not). The recommended practice is to use a data pump process for sending data to the remote data server collector, thereby keeping the primary extract dedicated for change data capture only.
·         The secondary extract is referred to as the data pump process, and it reads the local trail file and routes data to remote system. The data is received by a dedicated data collector server.

    Figure 1-13: GoldenGate processes architecture
·         The local trail is a canonical file format, created by the primary extract, which is read by the database pump process or other Oracle GoldenGate utilities such as LOGDUMP.
·         The data collector server is a background process associated with either a primary extract or a secondary extract. The function of the data collector server the receiving, re-assembling and creating of the remote trail on the target system.
·         The remote trail is a canonical file format, created by the data collector server. Purging of remote trail files is defined by purgeaoldextracts parameter.
·         The replicate process (or replicat for short) reads the remote trail file and applying the transactions to the remote database, with data integrity and consistency.
