How to create Oracle AWR report for a single instance Oracle database

To create the AWR report for a single instance Oracle database (use awrrpt.sql) as:

1. Find the script
2. Login as sysdba
3. Execute the script. While executing supply the following:

a. format of the report (html/text)

b. for number of days (don’t enter anything if you want to generate for specific snapshots). press enter

c. enter starting snapshot id from the displayed list

d. enter ending snapshot id from the displayed list

e. give a name for the report including file extension (txt/html/htm)

4. Once report is generated you exit sql*plus and view the report in the server or
5. transfer the report to your local machine and view it.

Here are the steps:

[oracle@DEVSERV ~]$ ls -l /u01/app/oracle/product/11.1.0/db_1/rdbms/admin/awrr*
-rw-r–r– 1 oracle oinstall 7575 Apr 18  2005 /u01/app/oracle/product/11.1.0/db_1/rdbms/admin/awrrpti.sql
