Oracle - > auto send AWR Report
September 21, 2016

Requirement Description:
Daily or regular manual use of AWR reports to check the status of Oracle database is not only time-consuming but also labor-intensive, requiring the use of scripts to automatically collect AWR reports.
Analysis scheme:
Script to collect AWR report: $oracle_home / RDBMS / admin / awrrpt. SQL - > main run script.
First, let's see what the script has done and what views it has used.
Cat $Oracle | home / RDBMS / admin / awrrpt.sql | grep - V 'Rem' | grep - V '^ --' (exclude 'Rem' and '--'
Get main information - >
select d.dbid dbid
, d.name db_name
, i.instance_number inst_num
, i.instance_name inst_name
from v$database d,
v$instance i;
And associated scripts @ awrrpti
See what the @ awrrpti script does
Cat $Oracle | home / RDBMS / admin / awrrpt.sql | grep - V 'Rem' | grep - V '^ --' (exclude comments related to 'Rem' and '--'
Get the core content - >
spool &report_name; select output from table(dbms_workload_repository.&fn_name( :dbid, :inst_num, :bid, :eid, :rpt_options )); spool off; select output from table(dbms_workload_repository.&fn_name( :dbid,:inst_num,:bid, :eid,:rpt_options )); &fn_name->The type name is as follows awr_report_html and awr_report_text :dbid->data base id Number :inst_num->Instance name :bid->snap start id :eid->snap End id :rpt_options->Control display ADDM
Association script
@@awrinput.sql - > get snapshot ID
@@Awrinpnm.sql 'awrrpt' & & ext - > main AWR report name
AWR script generation process:
@awrrpt.sql (provide dbid and inst_num)
@ @ awrrpti.sql (main script)
@ @ awrinput.sql (provide snap id)
@ @ awrinpnm.sql (provide awr build name)
Select output from table (DBMS ﹣ workload ﹣ repository. & FN ﹣ name (: dbid,: Inst ﹣ num,: bid,: Eid,: RPT ﹣ options)); (generate awr report)
Script development: < ora auto awrrpt. SQL >
Copy the contents of @ awrrpti.sql and correct them
