12 OSWatcher 12

13 OSWatcher OSWatcher (Doc ID ) OSWatcher Analyzer User Guide (Doc ID ) OSWatcher captures performance metrics from the operating system. oswbb: a unix shell script data collector which collects and stores the data oswbba: a java utility which will analyze the data automatically and provide advice and produce graphs and an html document TFA will install and run OSWatcher automatically. It will also update OSWatcher on a regular basis. 13

16 Trace File Analyzer (TFA) 16

17 Trace File Analyzer TFA Collector - TFA with Database Support Tools Bundle (Doc ID ) The Support Bundle Every DBA Needs Provides one interface for all diagnostic needs Collects data across the cluster and consolidates it in one place Collects all relevant diagnostic data at the time of the problem All the database tools you need in one bundle 17

18 Trace Analyzer 18

19 TRCANLZR (TRCA) TRCANLZR (TRCA): SQL_TRACE/Event Trace File Analyzer - Tool for Interpreting Raw SQL Traces (Doc ID ) TRCA inputs one or several SQL trace(s) generated by Event and outputs a diagnostics report in two formats (html and text). TRCA identifies expensive SQL out of the provided trace(s), then it connects to the database and collects their explain plans, Cost-based Optimizer CBO statistics, metadata, configuration parameters, and similar elements that influence the performance of the process being analyzed. Unix, Linux and Windows platforms Unwrapped source (SQL and PL/SQL) Installs under its own schemas (self-contained) Small footprint (space and CPU) Not intrusive (does not expose application data) Provides more information than TKPROF 19

21 SQLTXPLAIN 21

22 SQLTXPLAIN (SQLT) All About the SQLT Diagnostic Tool (Doc ID ) SQLT inputs one SQL statement and outputs a set of diagnostics files. These files are commonly used to diagnose SQL statements performing poorly. SQLT connects to the database and collects execution plans, Cost-based Optimizer CBO statistics, schema objects metadata, performance statistics, configuration parameters, and similar elements that influence the performance of the SQL being analyzed. 22

24 EDB360 24

25 EDB360 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 use cases: Keystone of an Oracle database Health-Check. Kick-off for an Oracle database Performance Evaluation. High-level view of System Resources demand and utilization for an Oracle database Sizing and Provisioning project.

27 SQLD360 27

28 SQLD360 SQLd360 is a free tool that provides a 360-degree overview around a SQL statement. The output is a single zip file that allows offline analysis, trend analysis and detailed rootcause investigations. The content of the zip is a set of small reports, each specific to an area of interest, easy to navigate through an index file. SQLd360 doesn t require any installation and can be executed by any user that has access to dictionary views. SQLd360 works successfully in 10g, 11g and 12c, specifically on Linux/Unix platforms. 28
