How to create AWR report manually

Oracle database 10g

If you do not have Oracle Enterprise Manager tool installed then you can create the AWR

reports manually using the following commands:

1. Creating Snapshot

BEGINDBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();END;/

The list of the snapshot Ids along with database Ids is availabe in the viewDBA_HIST_SNAPSHOT.

2. Dropping a Range of Snapshots.

Refer to the DBA_HIST_SNAPSHOT view column SNAP_ID to view availablesnapshots. To delete contain SNAP_ID from from 102 to 122,

BEGINDBMS_WORKLOAD_REPOSITORY.DROP_SNAPSHOT_RANGE (low_snap_id =>102, high_snap_id => 122, dbid => 8187786345);END;/

3. Modifying Snapshot Settings

If you want to modify the retention period as 43200 minutes (30 days), the intervalbetween each snapshot is specified as 30 minutes, and the number of Top SQL to flush

for each SQL criteria as 100 then use following:

BEGINDBMS_WORKLOAD_REPOSITORY.MODIFY_SNAPSHOT_SETTINGS( retention=> 43200,interval => 30, topnsql => 100, dbid => 7123356265);END;/The dbid is optional.

4. Extract the AWR Data

The awrextr.sqlscript extracts the AWR data for a range of snapshots from the databaseinto a Data Pump export file. Once created, this dump file can be transported to anothersystem where the extracted data can be loaded. To run the awrextr.sql script, you need tobe connected to the database as the SYS user.

To extract AWR data at the SQL prompt, enter:

SQL> @$ORACLE_HOME/rdbms/admin/awrextr.sql

5. Load the AWR Data

Once the export dump file is transported to the target system, you can load the extractedAWR data using the awrload.sql script. The awrload.sql script will first create a stagingschema where the snapshot data is transferred from the Data Pump file into the database.The data is then transferred from the staging schema into the appropriate AWR tables. To

run the awrload.sql script, you need to be connected to the database as the SYS user.

To load AWR data at the SQL prompt, enter:

SQL> @$ORACLE_HOME/rdbms/admin/awrload.sql

6. Generate AWR Reports

The awrrpt.sql SQL script generates an HTML or text report that displays statistics for arange of snapshot Ids.To generate an HTML or text report for a range of snapshot Ids, run the awrrpt.sql scriptat the SQL prompt:

SQL> @$ORACLE_HOME/rdbms/admin/awrrpt.sql

First, you need to specify whether you want an HTML or a text report.

Enter value for report_type: text

Specify the number of days for which you want to list snapshot Ids.

Enter value for num_days: 2

After the list displays, you are prompted for the beginning and ending snapshot Id for theworkload repository report.

Enter value for begin_snap: 95Enter value for end_snap: 97

Next, accept the default report name or enter a report name. The default name is acceptedin the following example:

Enter value for report_name:Using the report name awrrpt_1_95_97

The workload repository report is generated.
