How to configure eDB360?

leave a comment »

eDB360 has two execution parameters. The first one specifies if the database is licensed to use the Tuning or Diagnostics packs (or none). The second parameter is optional, and if entered it specifies the name of a custom configuration file that allows to change the behavior of eDB360. With this optional configuration file you can make changes such as: reduce the scope of the output to maybe a single column, a section, or even a range of sections. You can also change the time window from the default (last 31 days) to a larger window (if your AWR retention period allows) or smaller window. You can also specify a particular range of dates, or include additional report formats such as text, csv or xml.

If you are an experienced user of eDB360, you may want then to familiarize yourself with the configuration file sql/edb360_00_config.sql (listed below) and the sample custom configuration file provided (sql/custom_config_01.sql). Then you may want to assembly your own configuration file as a subset of the DEF values from sql/edb360_00_config.sql, and provide the name of your custom configuration script as the second execution parameter for eDB360. Your configuration file should reside under edb360-master/sql and the filename is case sensitive.

/*************************** ok to modify (if really needed) ****************************/

-- include DBA_SEGMENTS on queries with no filter on segment_name (default Y)
-- note: some releases of Oracle produce suboptimal plans when no segment_name is passed
DEF edb360_conf_incl_segments = 'Y';

-- include DBMS_METADATA calls (default Y)
-- note: some releases of Oracle take very long to generate metadata

/************************************ modifications *************************************/

-- If you need to modify any parameter create a new custom configuration file with a
-- subset of the DEF above, and place on same edb360-master/sql directory; then when
-- you execute edb360.sql, pass on second parameter the name of your configuration file
