Oracle GoldenGate Processes for ZDT

ZDT requires a set of Oracle GoldenGate processes. Some of the processes extract and replicate data from the active environment to the passive environment.

The following table identifies the prefixes that are used in the process group names:

Prefix	Process Type	Purpose
E_, P_	EXTRACT	Extracts data from the MDM Hub that is located in the active environment.
R_	REPLICAT	Replicates data to the MDM Hub that is located in the passive environment.

For example, the following list shows the processes for ENVA and ENVB, where ENVA is the active environment.

GGSCI (hostname) 13> info all

Program     Status      Group      
MANAGER     RUNNING
EXTRACT     RUNNING     E_ENVA   
REPLICAT    RUNNING     R_ENVB 
REPLICAT    RUNNING     R_ENVBU
