AWR report generator

​

The Automatic Workload Repository is a set of internal Oracle database dictionary tables and a special MMON background process that was introduced in Oracle10g .

​

Periodically, AWR creates a statistical copy (snapshot) and stores information in tables located in the SYSAUX tablespace. By default, the regular collection period is set to 60 minutes. This value can be reduced to 10 minutes if desired.

​

• From the Start_id drop-down list, select the ID of the snapshot from which to generate the report

• From the End_id drop-down list, select the snapshot ID, ending with which to generate a report

• Press the Show button

select *

  from table(DBMS_WORKLOAD_REPOSITORY.AWR_REPORT_HTML(

               (select dbid from v$database),

               1,

               <Start_id>,

               <End_id>)

       )

​​

The generated report will be placed in the tmp folder with the name  awrtmp.html , as well as stored in the local database in a table  CND$AWR_REPORT (base CoreDB.db)

The program allows you to manually compare two previously generated reports.

​

• Generate reports for arbitrary periods

• In the "List AWR" list, set the radio buttons opposite the generated reports

• Press the "Compare select" button
