ERROR OGG-08221 Cannot Register Or Unregister EXTRACT OCI Error 24,001

GGSCI> register extract EXTRACT-NAME database

   ERROR OGG-08221 Cannot register or unregister EXTRACT EXTRACT-NAME because of the following SQL error: OCI Error 24,001.


CAUSE
An integrated extract with the same name was already registered in the database.

SOLUTION
In this particular case it was a new database where they were trying to register a new Integrated Extract, no one ever had created an IE with the same name earlier but this database where they were trying to register the integrated extract was actually copied/cloned from an existing database which had Integrated Extracts registered.

As per company's standard they wanted to register an IE with the same name  and were not able to do so.



First the below was tried but didn't help:

SQL> execute DBMS_AQADM.DROP_QUEUE_TABLE (queue_table => 'OGG$<<Queue-Table-Name>>', force => true);



To resolve the issue all the objects pertaining to the extract name were first queried from the dictionary (dba_objects) and then dropped using below statement before registering the extract successfully:

       SQL> execute DBMS_AQADM.DROP_QUEUE_TABLE (queue_table => 'AQ$_<<Queue-Table-Name>>_T', force => true);

       SQL> execute DBMS_AQADM.DROP_QUEUE_TABLE (queue_table => 'AQ$_<<Queue-Table-Name>>_H', force => true);

       SQL> drop sequence AQ$_<<Queue-Table-Name>>_N;

       SQL> drop view AQ$OGG$<<Queue-Table-Name>>_S;

       SQL> drop view AQ$OGG$<<Queue-Table-Name>>_R;

     etc...
