1.4 Oracle GoldenGate Commands

GGSCI is the command-line interface that lets you interface with all Oracle GoldenGate components. Throughout this guide, you will see GGSCI commands described; they are your primary tools for configuring, operating, managing, and troubleshooting your data management environment.

Output from the Oracle GoldenGate GGSCI interface supports up to 1024 processing groups, including Extract, Coordinator, Syncfile, and Replicat groups. At the supported level, all groups can be controlled and viewed in full with the GGSCI commands, such as INFO and STATUS commands. Beyond that supported level, group information is not displayed and errors can occur. Oracle GoldenGate recommends keeping the combined number of processing groups at 1024 or below in order to manage your environment effectively.

1.4.1 To Start GGSCI

Before you can start GGSCI, you must navigate to the Oracle GoldenGate installation location. When you are in the correct subvolume, enter RUN GGSCI. Your prompt will change to a GGSCI prompt. For example:

Example 1-1 Starting GGSCI

TACL> VOLUME $DATA.GGS 
TACL> RUN GGSCI 
GGSCI> 

After you have the GGSCI command prompt, enter GGSCI commands on the command line as needed. With GGSCI commands, you can edit parameter files, add groups, view reports, and communicate with running processes. For more information, see Reference for Oracle GoldenGate on HP NonStop Guardian.
