One of my customers asked me to check performance on his production database server but could not allow any access to the server itself. He asked if I could generate the AWR reports from his client machine and since it’s not really trivial (or hard) I created this script.
When we want to generate the AWR report, we usually run the awrrpt.sql script. We don’t need to be on the database server for that – we just need the awrrpt script and the scripts it calls – so any database server installation will do. Once we connect to the database and run the script, it will automatically run the relevant queries and scripts and generate the report.
Underneath all the scripts there is DBMS package called DBMS_WORKLOAD_REPOSITORY which we can call ourselves. In this case, since I didn’t have the scripts, I had to use it but I can think of other cases where it make sense to use it (for example, for generating multiple reports, or automatically send reports by email).
There are two ways to generate the report. We can generate a text version or HTML version – and indeed, there are two functions for that: AWRRPT_HTML_TYPE_TABLE and AWRRPT_TEXT_TYPE_TABLE. Those function accept these parameters, so let’s see where we get the data for that:

FUNCTION AWR_REPORT_HTML RETURNS AWRRPT_HTML_TYPE_TABLE Argument Name Type In/Out Default? ------------------------------ ----------------------- ------ -------- L_DBID NUMBER IN L_INST_NUM NUMBER IN L_BID NUMBER IN L_EID NUMBER IN L_OPTIONS NUMBER IN DEFAULTFUNCTION AWR_REPORT_TEXT RETURNS AWRRPT_TEXT_TYPE_TABLE Argument Name Type In/Out Default? ------------------------------ ----------------------- ------ -------- L_DBID NUMBER IN L_INST_NUM NUMBER IN L_BID NUMBER IN L_EID NUMBER IN L_OPTIONS NUMBER IN DEFAULT |
In order to get the DBID, Instance number and a list of snap ids we can use (here, from the last day), we can run this query:
|
1

4
|
SELECT DBID, instance_number, snap_id, begin_interval_time, end_interval_time FROM dba_hist_snapshot where begin_interval_time > sysdate - 1 ORDER BY snap_id |
In order to generate the report as cleanly as possible we can use this script.
For HTML output:
