SQL Statements below recover the data from a timestamp just before the offending SQL update was carried out. I saved the data to a _BAK table.

Subject: recoverd *********** table using oracle flashback query

Importance: High

Hi ****

I was able to recover the table using flashback query. See below.

Please check the data in the table ********_BAK it contains the data in ******** as of 2010-09-22 09:00:00. The offensing update was carried out at 9:10 hours.

When the data is OK I can merge the data from the _BAK table to the original production table.

SQL> create table ********_BAK
  2  as
  3  SELECT * FROM BAGR.********    AS OF TIMESTAMP 
  4     TO_TIMESTAMP('2010-09-22 09:00:00', 'YYYY-MM-DD HH:MI:SS')
  5  ;

Table created.

 
SQL> create public synonym ********_BAK for ********.********_BAK;

Synonym created.

 
SQL> grant select on ********.********_BAK to public;

Grant succeeded.

Dutch people, notice the schema owner name ‘BAGR.********’, Hello my name is ‘BAGR’, how nice…

I prefer SYS.WRM$_SNAPSHOT instead of DBA_HIST_SNAPSHOT because I saw strange results in (Release 10.1.0.5).

Now use the dbms_workload_repository package to remove the AWR snapshots.

BEGIN                                                               
  dbms_workload_repository.drop_snapshot_range(low_snap_id => 7556, high_snap_id=>15000);

Speed up ‘removal’ of old AWR reports

@#$%^&*()_ removing the entries takes ages and fails on undo errors … Metalink note Doc ID: 852028.1 states that I can safely remove the AWR metadata tables and recreate them.

If none of the above suits as everything is set proper then consider clean up and rebuild AWR repository to clear all the space.

Here’s the scenario:

1. You have an Alert that your tablespace is ‘full’,
2. You enlarge the tablespace,
3. The ‘Tablespace Full Alert’ is still in your dashbord for the next 24 (x) hours since you’ve configured this metric to be collected once every 24 (x) hours,
4. You want however to ‘remove’ (clear) this Alert. In order to achive this you will have to to re-evaluate this metric collection …

Here is how you do it (for anything storage related on your database server):

$ emctl control agent runCollection <hostname>:host host_storage

See the Oracle docs, 2.7.6 Reevaluating Metric Collections. It shows you how to retrieve the correct collection name for any metric.

You will find yourself grep-ing through ‘$ORACLE_HOME/sysman/admin/metadata/*xml’ and ‘$ORACLE_HOME/sysman/admin/default_collection/*xml’ …
