OSWatcher Schell script to collect and archive OS Metrics Executes standard UNIX utilities (e.g. vmstat, iostat, ps, etc) on regular intervals Built in Analyzer functionality to summarize, graph and report upon collected metrics Output is Required for node reboot and performance issues Simple to install, extremely lightweight Runs on ALL platforms (Except Windows) MOS Note: 301137.1 – OS Watcher Users Guide

CHM Cluster Health Monitor Installed on ALL platforms (except HPUX) with Grid Infrastructure 11.2.0.3+ Collects OS Metrics in Real Time at 5 second intervals OS Metrics include Memory, CPU, Swap, I/O, etc Data retention < 1 day (dependent on cluster size) and may be increased – See MOS Note: 1921105.1 Output Required for Node Reboot and Performance Issues Both CHM and OSW are recommended where available MOS Note: 1328466.1 – CHM FAQ

Procwatcher Tool to continuously monitor and examine Oracle Database and RAC processes at a specified interval Generates session wait, lock and latch reports as well as call stacks from any problem process(s) Ability to collect stack traces of specific processes using Oracle Tools and OS Debuggers Typically reduces SR resolution for performance related issues Runs on ALL major UNIX Platforms MOS Note: 459694.1 – Procwatcher Install Guide

TFA Trace File Analyzer Collector Diagnostic Collection utility that simplifies diagnostic data collection A single command performs clusterwide diagnostic collection for ALL components Diagnostic files “trimmed” around the incident time Collected diagnostics are consolidated on a single node Increased efficiency of admin staff Packaged with 11.2.0.4/12.1.0.2 – standalone available Note: 1513912.1

TFA vs Traditional Diagnostics Collection Manual copying/archiving files from multiple locations on a given system and must be repeated for ALL nodes Diagnostics for a given node often exceed 350MB, for a 4 node cluster this is 1.4 GB of data to upload to MOS. The customer needs to manually get the correct data covering the correct time If the data was not properly gathered during the first outage we must “wait” for a re-occurrence of the issue Node Reboot (All Nodes) diagcollection.sh output OSWatcher CHMOS output Instance Eviction (All Nodes) ASM/DB Alert Logs ASM/DB Trace Files

TFA vs Traditional Diagnostics Collection TFA Approach Proper diagnostics for an incident collected, trimmed and packaged around the incident time with a single command One .zip file per cluster node generated and each are consolidated on a single node Greatly reduced file size containing only data for a particular incident for ease of upload Optionally perform diagnostic collection automatically when an incident is detected by TFA All Scenarios # tfactl diagcollect -for <time> Note: Alternatively enable Real Time Automatic Diagnostic Collection

TFA - Requirements Supported Platforms Linux x86/x86-64 (OEL, RedHat and SuSE 9, 10, 11) Oracle Solaris (SPARC and x86-64) IBM AIX HP-UX zLinux Supported Oracle Releases All – TFA is written outside the GI/RAC/RDBMS product lines and as such could be used for any type of trace/diagnostic file collection Note: BASH shell and JRE 1.5 or higher are required on ALL platforms
