OBIEE 11.1.1 - Tuning Guide Script v1

The obiee tuning guide available here https://blogs.oracle.com/proactivesupportEPM/entry/wp_obiee_tuning_guide lists a number of checks for optimization.

The script attached here //cdn.app.compendium.com/uploads/user/e7c690e8-6ff9-102a-ac6d-e4aebca50425/f4a5b21d-66fa-4885-92bf-c4e81c06d916/File/861e8391c6334e32f4038fc42b47b8c7/checkobieetuningguidev4_01_2014.zip automates these checks. It is only reading from the obiee server and it will not modify any values. The script outputs the current values, that you can compare with the recommended ones.

* copy the python script and tuningGuide.properties in a folder on the obiee server. This machine contains an oracle_common/common/bin/wslt.sh (.cmd)
* Modify tuningGuide.properties
