======Configuration of the source======
To configure the source database we have to do two things:

  * Ensure the database is set correctly.
  * Ensure the GoldenGate is set correctly.

Both need to be configured if you want the Golden Gate to work properly.

=====Configure Database=====
We have to ensure that we have enabled:

  * Supplemental logging
  * Golden Gate Replication
  * Force Logging
  * Necessary rights for the user


So let's get started. You can set supplemental logging in Oracle database in three levels:

<Code:bash|Database Level>
SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
SQL> ALTER DATABASE FORCE LOGGING;
</Code>

<Code:bash|Schema Level>
GGSCI> ADD SCHEMATRANDATA schema [ALLCOLS|NOSCHEDULINGCOLS]
</Code>

<Code:bash|Table Level>
GGSCI> ADD TRANDATA [container.]schema.table[ALLCOLS|NOSCHEDULINGCOLS]
</Code>

The commands from the GGSCI are heterogenous, which means, if the database is DB2, it will enable the necessary logging for DB2.

<Code:bash|Enable Supplemental Logging>
[oracle@edvmr1p0 les03]$ sqlplus / as sysdba
SQL> SELECT supplemental_log_data_min, force_logging FROM v$database;
SUPPLEME FORCE_LOGGING
-------- ---------------------------------------
NO	 NO

SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;

Database altered.
SQL> ALTER DATABASE FORCE LOGGING;

Database altered.

SQL> ALTER SYSTEM SWITCH LOGFILE;

System altered.

SQL> SELECT supplemental_log_data_min, force_logging FROM v$database;
SUPPLEME FORCE_LOGGING
-------- ---------------------------------------
YES	 YES

</Code>

<Code:bash|Enable Replication>
SQL> show parameter enable_goldengate

NAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
enable_goldengate_replication	     boolean	 FALSE
SQL> 
SQL> 
alter system set enable_goldengate_replication=true scope=both;
System altered.
SQL> show parameter enable_goldengate

NAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
enable_goldengate_replication	     boolean	 TRUE
</Code>

Finally, grant the necessary rights to the user:
<Code:bash|Grant rights to user>
SQL> exec dbms_goldengate_auth.grant_admin_privilege('C##OGG_ADMIN',container=>'all');
                                                         user                   containers...duh :)
PL/SQL procedure successfully completed.
SQL> 
</Code>

=====Configure Golden Gate=====

In order to configure a export on the SOURCE, we should configure 3 jobs:

  * Manager
  * Extract Job <- Reads the redo
  * Dump Job  <- Takes the information from the previous job and dump it into retail file.

Create the configuration file with the same name as you want the JOB name to be called.

===Manager===
<Code:bash|Manager Config>
[oracle@matar dirprm]$ cat mgr.prm

</Code>



===Extract job: EBKEXT1===
<Code:bash|Extract Config>

Table schema_name2.* ;    
</Code>


====Add the job to the configuration====
The jobs should be added to the configuration as well using the GoldenGate Software Command Interface(GGSCI)

After the server added configuration of the schema into the configuration, we can check and start the jobs:

Wait them for couple minutes, to assure that they will not end abnormally (ABEND)
