Enkitec’s Oracle Database 360-degree View
EDB360 is a free tool that executes on an Oracle database and produces a compressed file which includes a large set of small Reports. This set of Reports provides a 360-degree view of an Oracle Database. EDB360 is mostly used for one of the following 3 reasons, listed here in order of frequency of use: 1) Keystone of an Oracle database Health-Check. 2) Kick-off for an Oracle database Performance Evaluation. 3) High-level view of System Resources demand and utilization for an Oracle database Sizing and Provisioning project.
Usually, Developers, Sys Admins and Consultants are not given open access to a database in a Production environment. This eDB360 free tool helps approved users to become familiar with an Oracle database in a non-intrusive way. Without installing anything on the database, the eDB360 tool connects to an Oracle database and produces a large set of flat files that can be reviewed offline while using an HTML browser or a Text editor.
EDB360 can be executed by someone with very limited access to an Oracle database (i.e. a Developer, Sys Admin or Consultant with just query access to the Data Dictionary views); or if executed by an authorized DBA, there is no actual need to provide any additional access to the Oracle database to the party requesting eDB360.
EDB360 works on 10gR2, 11gR2, and on higher releases of Oracle; and it can be used on Linux or UNIX Platforms. It has not been tested on Windows. An eDB360 sample output is available at this Dropbox location; after downloading the sample output, look for the 0001_edb360_dbname_index.html file and start browsing.
Download the eDB360 tool and review the readme.txt file included. Uncompress the eDB360 master ZIP file on the Database Server of interest. Navigate to the main eDB360 (master) directory and execute script edb360.sql connected as SYS or any other account with access to the Data Dictionary views (a DBA account is not required but it is preferred).
Execution time for eDB360 may exceed 1 hour, depending on the size of the Data Dictionary. And the size of the output may reach 1 GB, so be sure you execute this tool from a file system directory with at least 1 GB or free space. Common sizes of the output range between 10 and 100 MB.
EDB360 has only two execution parameters:
- Oracle Pack License: A big portion of the information presented by eDB360 comes from Oracle’s Automatic Workload Repository (AWR), and AWR is licensed by Oracle under the Diagnostics Pack. A small part of the output of eDB360 comes from the SQL Monitoring repository, which is part of the Oracle Tuning Pack. This parameter accepts one of 3 values: “T”, “D” or “N”. If you database is licensed under the Oracle Tuning Pack, enter then the value of “T”. If your database is not licensed to use the Oracle Tuning Pack but it is licensed to use the Oracle Diagnostics Pack, enter “D” then. If your site is not licensed on any of these two Oracle Packs, enter “N” then. Be aware that a value of “N” reduces substantially the content and value of the output. Thus the preferred parameter value is “T” (Oracle Tuning Pack).
- Days of History?: Assuming you pass a value of “T” or “D” on the 1st parameter, this second parameter defines how many days of History are accessed by eDB360 out of AWR. The default value is 31, but if your actual AWR setup preserves only 8 days (AWR default), then eDB360 will limit its content to the smaller of the two. For most cases, the default value of 31 is the right one to choose, specially when unsure about the actual AWR retention period.
