After successfully installing Oracle GoldenGate 12c, it will create a lot of sub-directories structure which will be used by the different components of Oracle GoldenGate. There are so many directories that new user will get confused what to look where.The directories are the default locations for GoldenGate when creating objects and parameter files.
Below are the brief description of each directory:
| Sub-directories | Description |
| dirbdb | This directory contains the GoldenGat e datastor e files |
| dirchk | This directory contains the GoldenGate checkpoint files. Extract and Replicat processes stores current read and write positions in the checkpoint file to support data accuracy and fault tolerance. Extension of the file is either .cpe for Extract checkpoint files or .cpr for Replicat checkpoint files. |
| dircrd | This directory contains the GoldenGate Credential Store |
