This example will illustrate the installation of Oracle GoldenGate on an RHEL 5 platform. We had in an earlier post discussed the architecture and various components of a GoldenGate environment.
GoldenGate software is also available on OTN but for our platform we need to download the required software from the Oracle E-Delivery web site.
Select the Product Pack “Oracle Fusion Middleware” and the platform Linux X86-64.
Then select “Oracle GoldenGate on Oracle Media Pack for Linux x86-64″ and since we are installing this for an Oracle 11g database, we download “Oracle GoldenGate V10.4.0.x for Oracle 11g 64bit on RedHat 5.0″
$ unzip V18159-01.zip

We then need to create a database user which will be used by the GoldenGate Manager, Extract and Replicat processes. We can create individual users for each process or configure just a common user – in our case we will create the one user GGS_OWNER and grant it the required privileges.
SQL> create tablespace ggs_data
2 datafile ‘/u02/oradata/gavin/ggs_data01.dbf’ size 200m;
SQL> create user ggs_owner identified by ggs_owner
2 default tablespace ggs_data
3 temporary tablespace temp;
User created.
SQL> grant connect,resource to ggs_owner;
Grant succeeded.
SQL> grant select any dictionary, select any table to ggs_owner;
Grant succeeded.
SQL> grant create table to ggs_owner;
Grant succeeded.
SQL> grant flashback any table to ggs_owner;
Grant succeeded.
SQL> grant execute on dbms_flashback to ggs_owner;
Grant succeeded.
SQL> grant execute on utl_file to ggs_owner;
Grant succeeded.
We can then confirm that the GoldenGate user we have just created is able to connect to the Oracle database

We also need to enable supplemental logging at the database level otherwise we will get this error when we try to start the Extract process -
2010-02-08 13:51:21 GGS ERROR 190 No minimum supplemental logging is enabled. This may cause extract process to handle key update incorrectly if key
column is not in first row piece.
