What you could do is backup your database , take or archiving, drop AWR or re-run the purge again this time not generating archive log and the backup again later Let

John Hallas said July 21, 2015 at 3:24 pm I think that line was incorrect and not needed - It did not have a procedure name attached to the package. http://remidian.com/2009/08/purging-sysaux-tablespace-purging-awr-reports/ B.E,M.S,M.B.A,P.M.P,C.S.M Experience: is what you get soon after you need it. Purge Sysaux Tablespace Oracle 11g The current settings for AWR retention and interval parameters can be viewed using dba_hist_wr_control data dictionary view. How To Shrink Sysaux Tablespace In 11g Examples This example changes the interval setting to one hour and the retention setting to two weeks for the local database: EXECUTE DBMS_WORKLOAD_REPOSITORY.MODIFY_SNAPSHOT_SETTINGS( interval => 60, retention => 20160); If you
Then I look at the minimum snapshot ID in wrh$_active_session_history and it's days older than the 8 day retention period. There is a special mechanism which is used in the case of the large AWR tables where we store the snapshot data in partitions. AWR is essentially a Oracle built-in tools, which collects statistical data associated with performance, and from those statistics derived energy degrees, to track potential problems. Usage Notes You can call the function directly but Oracle recommends you use the awrsqrpt.sql script which prompts users for the required information. How To Reclaim Space From Sysaux Tablespace
Rebuilding objects was time consuming; I have too many databases. The resulting report can be opend in a browser or text editor accordingly. The components involved are the Automatic Workload Repository (AWR) and Optimizer Statistics History (OPTSTAT). SM/OPTSTAT SM/AWR -- It refers to Automatic Workload Repository.Data in this section is retained for a certain amount of time (default 8 days).

The largest segments in SYSAUX are WRH$ objects, like WRH$_EVENT_HISTOGRAM. There is the problem, all the WRH$ data is held in 2 partitions and the overnight house-keeping job does not have time to finish it's tidy-up before it's 15 minutes of The value for this setting will not be affected by the statistics/flush level and will override the system default behavior for the AWR SQL collection. Would I have to keep creating new partitions, from time to time?

MODIFY_SNAPSHOT_SETTINGS Procedures This procedure controls three aspects of snapshot generation. AWR is supposed to reuse the storage, but I have seen two ORA-01688 errors on WRH$ partitions in the last week.
For example, to generate an ASH report on MODULE "PAYROLL" and ACTION "PROCESS", use the following predicate: l_module => 'PAYROLL', l_action => 'PROCESS' Valid SQL wildcards can be used in all The ADDM report provides root cause analysis of the parts of the system consuming the most time. When looking at an AWR report, a good place to start is the "Top 5 Timed Foreground Events" section, near the top of the report.

Oracle8i introduced the Statspack functionality which Oracle9i extended. Some system and session statistics from the V$SYSSTAT and V$SESSTAT views. These are small, development databases that started out at 5 GB. And I probably would for this database.
Currently, Oracle supports one value: l_options - 8. Without it, the lone partition in each WRH$ table just keeps accumulating content, never aging out. For production, I would wait 9 days post-patch to see reclaimed free space.
