Architecture knowledge is important …
This chapter describe the basic architecture of Oracle Golden Gate. In this Architecture of Golden Gate chapter we will discuss components of Golden Gate. Along with components of Golden gate we will also cover in details about the architectural components of Golden Gate and features.
Architecture of Golden Gate is very important. To understand the concept of Golden Gate. Lets begin with diagram.
Components of Oracle Golden Gate:
Golden Gate supports different topology for data transfer. To know more about these topology or mode of data transfer you can read our post Oracle Golden Gate Modes
This section describes more about the architecture of the Golden Gate. These are follows
It contains list of tables or objects which need to replicates with target DB.
Manager process runs on source and target DB which managed the services also allocates dynamic port to the services.
Source database tables change recorded in local trail log file location if location specified in source extract parameters files.
If trail log file location in source DB then it read the trail log files and send it to the target DB for replication.
Data pump or extract process use networks to send trail log file to target DB trail log location location.
It collect the trail log in a sequence also in canonical format if it use Oracle.
It read the trail log file and replicate the changes in same sequence on target DB tables.
Dump or extract process writes the source DB tables changes into target DB trail file location .
Target DB: Target
Environments which use for replication of the source DB changes.
In this chapter we learnt about Architecture of Golden Gate. Addition to this also we have see explained components of OracleGolden Gate.
Hope this gives you basic Architectural knowledge of Golden Gate.
