How To Drop Extract Capture Process Permanently on GoldenGate

I will give some code and explain to how to drop extract capture processes permanently on GoldenGate.

You can drop all extract capture processes with the below PL/SQL code.

BEGIN
     FOR i IN (SELECT capture_name FROM dba_capture)
     LOOP
         DBMS_CAPTURE_ADM.STOP_CAPTURE(i.capture_name, true);
         DBMS_CAPTURE_ADM.DROP_CAPTURE (i.capture_name, true);
     END LOOP;
 END;
 /

If you want to continues manual, you can follow the below code. It will work.

$ sqlplus / as sysdba
SQL> select capture_name from dba_capture;
Result:
CAPTURE_NAME
-------------
GGS$CAP_DSSSDDSS
SQL> exec DBMS_CAPTURE_ADM.STOP_CAPTURE('GGS$CAP_DSSSDDSS', true);
SQL> exec DBMS_CAPTURE_ADM.DROP_CAPTURE('GGS$CAP_DSSSDDSS', true);

If your capture process status is active while operation time, probably you will get the below error. Before drop operation, you must call STOP_CAPTURE procedure. Otherwise, you will get the below error.

ORA-01338 Other process is attached to Logminer session
ORA-06512 at "SYS.DBMS_CAPTURE_ADM_INTERNAL", line 238
ORA-06512 at "SYS.DBMS_CAPTURE_ADM_INTERNAL", line 225
ORA-06512 at "SYS.DBMS_CAPTURE_ADM", line 268

Lastly, you can drop to GoldenGate capture process in GoldenGate bash terminal with the below code.

GGSCI> dblogin userid gguser password xxxx
GGSCI> stop extract_process_name
GGSCI> unregister extract extract_process_name
GGSCI> delete extract_process_name

How to Enable/Disable Unified Audit

Hello everyone, I want to explain how to enable/disable unified audit option on Oracle Databases. When you enable or disable unified audit option, all databases must be closed while operation time.

You can check the unified audit that open or closed status with the below code

SQL> SELECT VALUE FROM V$OPTION WHERE PARAMETER = 'Unified Auditing';

VALUE
-------
NO

You can open a unified audit option with the below code.

$ cd $ORACLE_HOME/rdbms/lib
$ make -f ins_rdbms.mk uniaud_on ioracle

When operation completed, you can check to unified audit status.

SQL> SELECT VALUE FROM V$OPTION WHERE PARAMETER = 'Unified Auditing';
VALUE
-------
YES

Also, you can purge to logs on the databases with the below code.

BEGIN 
DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL(
audit_trail_type =>  DBMS_AUDIT_MGMT.AUDIT_TRAIL_UNIFIED,
use_last_arch_timestamp =>  FALSE);
END; 
/

You can purge to logs on the OS with the below code.

EXEC DBMS_AUDIT_MGMT.DROP_PURGE_JOB('CLEANUP_OS_DB_AUDIT_RECORDS'); 


BEGIN 
DBMS_AUDIT_MGMT.DEINIT_CLEANUP( 
AUDIT_TRAIL_TYPE   => DBMS_AUDIT_MGMT.AUDIT_TRAIL_ALL); 
END;
/

Lastly, you can disable to unified audit with the below code.

$ cd $ORACLE_HOME/rdbms/lib
$ make -f ins_rdbms.mk uniaud_off ioracle

and check

SQL> SELECT VALUE FROM V$OPTION WHERE PARAMETER = 'Unified Auditing';

VALUE
-------
NO
