Use Backup to restore Oracle triggers ____oracle

After the system upgrade, one of the features is not normal, colleagues want to look at the upgrade before the stored procedures. The first thought is the flashback function, unfortunately, the flashback encountered a ORA-01555 error.

SELECT * from Dba_triggers as of TIMESTAMP to_timestamp (' 2014-06-19 05:25:00 ', ' yyyy-mm-dd hh24:mi:ss ')

WHERE OWNER = ' xxx ' and trigger_name = ' tri_ins_feedback ';

Fortunately there is a daily use of EXPDP generated metadata backup.

The advantage of the meta backup is that the backup speed is faster and the space used is relatively small. The disadvantage is that there is no data.

The previous Meta-data backup has not been used, this time it is finally used, otherwise it will take a long time to copy a huge backup to the test environment.

This time, the IMPDP in Oracle is used to restore the metadata of the database to the specified SQL file. The desired trigger was found from the SQL file.

It took nearly 10 minutes to develop the demand from development to find the appropriate trigger.

The Sqlfile function in the Import command IMPDP of the Oracle data pump enables the ability to export the DDL statements to the specified file without importing the data files to the database.

IMPDP testuser/testbj directory=dpumpdir dumpfile=metadata_2014-06-18_01.dmp sqlfile=meta_expdp.sql ENCRYPTION_ Password=password

After the DDL statements are imported into the SQL file, we can search the exported files through the editor to find what we need.
