Add the GoldenGate directory to your LD_LIBRARY_PATH and PATH
export PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:/u01/app/oracle/ggs
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/u01/app/oracle/ggs/lib
The first step is to open the GoldenGate command line interface and to create the necessary subdirectories
[oracle@ggos ggs]$ ./ggsci
Oracle GoldenGate Command Interpreter for Oracle

The second step is to create a parameter file for the manager which at least contains a PORT number for the manager
GGSCI (ggos) 3> edit param mgr
add the following content to the parameter file
GGSCI (ggos) 2> view param mgr
PORT 7809
Save the parameter file, exit from the editor, start the manager and verify if it is running
GGSCI (ggos) 1> start mgr
Manager started.
GGSCI (ggos) 2> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
GGSCI (ggos) 3> info mgr
Manager is running (IP port ggos.7809).
Installing and setting up Oracle GoldenGate on the PostgreSQL machine
Then add the lib directory to the LD_LIBRARY_PATH and PATH
export LD_LIBRARY_PATH=/data/pgsql/lib:/data/pgsql/ggs/lib
export PATH=/data/pgsql/bin:/data/pgsql/ggs:$PATH
GoldenGate uses an ODBC connection to connect to the Postgres database. The ODBC driver is shipped with the installation and on Unix you have to create the ODBC configuration file which is commonly called odbc.ini on your own
Here the file I used
[postgres@ggpgt ggs]$ pwd
/data/pgsql/ggs
[postgres@ggpgt ggs]$ cat odbc.ini
