Currently, two reliable automatic AWR generation methods have been found on the Internet.
Method 1:
Reference SQL link: http://www.oracle-base.com/dba/10g/generate_multiple_awr_reports. SQL

The specific method is:
1. First Save the preceding SQL statement to the DB host, generate_multiple_awr_reports. SQL
2. view the AWR snapshot generated by the system:
SELECT snap_id, BEGIN_INTERVAL_TIME, END_INTERVAL_TIME FROM dba_hist_snapshot;
3. manually change the value of snap_id in the result obtained in step 2 to generate_multiple_awr_reports. SQL and replace the numbers 1 and 10:
Rochelle snap_start NUMBER: = 1;
Rochelle snap_end NUMBER: = 10;
4. call the SQL file in sqlplus
SQL> @ generate_multiple_awr_reports. SQL
5. check whether html files are generated in the/tmp directory.
Conclusion: in fact, this method is only suitable for replacing the sqlplus interactive command line. it does not work very effectively. Currently, tools such as TOAD directly provide AWR viewing tools.
