Hi,

As there was a database performance, we started to analyse the issue by running ADDM using below.

@?/rdbms/admin/addmrpt.sql

.

The result of running ADD is below.

          DETAILED ADDM REPORT FOR TASK 'TASK_64718' WITH ID 64718
          --------------------------------------------------------

              Analysis Period: 10-APR-2012 from 06:00:15 to 07:00:22
         Database ID/Instance: 324353546/1
      Database/Instance Names: JACK/jack1
                    Host Name: fdsfggwe001
             Database Version: 10.2.0.4.0
               Snapshot Range: from 26820 to 26822
                Database Time: 6 seconds
        Average Database Load: 0 active sessions

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

THERE WAS NOT ENOUGH DATABASE TIME FOR ADDM ANALYSIS.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

          ADDITIONAL INFORMATION
          ----------------------

There was no significant database activity to run the ADDM.

The database's maintenance windows were active during 100% of the analysis
period.

The analysis of I/O performance is based on the default assumption that the
average read time for one database block is 10000 micro-seconds.

An explanation of the terminology used in this report is available when you
run the report with the 'ALL' level of detail.

Note:
-------
Current parameters set in database are below

statistics_level ---- string

timed_statistics --- boolean

1.Do i need to set the initialization parameter to some other value?

2.should i run the below command before executing the ADD report ?

exec dbms_workload_repository.create_snapshot();

Kindly advice .

Regards,

You need to do nothing but some activity on your database.

And above all you need to understand what you do:

timed_statistics --- boolean

This is completely meaningless and seems to have been posted by someone with an IQ slighty above a tadpole.

There was some activity at that time on database.

While the tadpole comparsion was frankly unecessary, Michel does have a point that you weren't paying attention to what you posted.
You put the datatype of the parameters. We already know the datatype of the parameters. We need to know what they are actually set to in your DB.
