Introduction :
The Goldengate Manager is the first process that needs to be setup in the replication configuration. This process must be running on the source and the target system. It is an essential process as it is required to be able to configure and start the other Goldengate processes. It also manages the disk space by purging the old trail files periodically. It has to be noted that only one manager process is required for every Goldengate installation.
It is important to note that a simple configuration file mgr.prm, is required to start the manager process. All parameter files are placed in the $GG_HOME/dirprm directory. The GG_HOME is the home directory where GoldenGate binaries are installed.
