Solution Type Predictive Self-Healing Sure Solution 1662439.1 : Master Note On Exalytics Instrumentation And Diagnostics - Use To Diagnose and Troubleshoot Problems on Exalytics
In this Document
Applies to:Business Intelligence Suite Enterprise Edition - Version 11.1.1.6.0 to 12.2.1.3.0 [Release 11g to 12g]Linux OS - Version Oracle Linux 5.5 with Unbreakable Enterprise Kernel [2.6.32] and later Oracle TimesTen In-Memory Database - Version 11.2.2.2.0 and later Oracle Exalytics Software - Version 1.0.0.0.0 to 2.0.0.1.0 [Release 1.0 to 2.0] Exalytics In-Memory Machine X2-4 - Version All Versions and later Information in this document applies to any platform. Checked for currency 29-DEC-2015. PurposeThis is a master note on Exalytics Instrumentation / diagnostics utilities. DetailsWhat is meant by "Instrumentation" or "Diagnostics"The terms "Instrumentation" and "Diagnostics" are used interchangeably and refer to tools that help collect, inform, diagnose, or troubleshoot. These features can be used by Oracle customers and Oracle Support to diagnose product and hardware problems. The following Exalytics Instrumentation/ Diagnostics tools and their suggested use cases are available:
Hardware Instrumentation and DiagnosticsAuto Service request (ASR) - use to monitor hardware and components and automatically open Support Request (SR) when errors detectedOracle Auto Service Request (ASR) is a feature of Oracle Premier Support for Systems and Oracle/Sun Limited Warranty that is designed to automatically request Oracle service when specific hardware faults occur. ASR is designed to enable faster problem resolution by eliminating the need to initiate contact with Oracle services for hardware failures, reducing both the number of phone calls needed and overall phone time required. For more information on ASR refer to following documentation links:
ASRExacheck - use to validate communication between Exa* nodes and ASR ManagerThe ASREXACHECK script is designed to check and test ASR configurations to make sure that the Exa* nodes can communicate to the ASR Manager. This is a non-invasive script that checks configurations only and does not write to any system or configuration files. The asrexacheck script also checks for known configuration issues as well as checking for any previous hardware faults that may not have been reported by ASR due a misconfiguration on the Engineered nodes. The script can be used on all nodes as well on OEL nodes and Solaris DB Nodes.The Script is now supported on the following platforms of Engineered Systems:
Refer to following MOS Notes for more information on ASREXACHECK
Exalytics Diagnostics - use to collect disk sub-system information when disk error suspectedThe Exalytics Diagnostics script (exalyticsdiag.sh) is a diagnostic collection tool for the Oracle Exalytics In-Memory Machine. It collects various files and outputs from the system and packages them into a tar.bz2 file that can be easily uploaded to a support case to assist the support center in troubleshooting issues. The script can optionally take two different options to include data collection from the system's Service Processor. The 'ilom' option will collect several outputs from the ipmitool command (see below for a list of the commands) and the 'snapshot' option will collect an ILOM snapshot from the Service Processor. Refer to following MOS Note for more information on exalyticsdiag.sh:
ILOM Snapshot - use to collect service processor diagnostic data for failing/failed hardware components (dimm, processor, fan, power supply, etc.)The ILOM snapshot is a tool used to collect diagnostic data on the server processor. It is useful when encountering problems with warning lights (on the server itself), or hardware errors (in ILOM or other). The ILOM snapshot can be run via GUI mode in the ILOM console or on the service console itself (via the SP CLI interface). See the following note for full instructions:
Linux Operating System and Oracle Virtual Machine (OVM)OSWatcher - use to collect operating system and network metrics for Linux performance issuesOS Watcher (OSW) is a collection of UNIX shell scripts intended to collect and archive operating system and network metrics to aid support in diagnosing performance issues. Refer to following MOS Notes for more information on OSWatcher.
Sosreport - use to collect operating system data including network configuration and logs for Linux OS issuesThe "sosreport" is a tool to collect troubleshooting data on an Oracle Linux system. It generates a compressed tarball of debugging information that gives an overview of the most important logs and configuration of a Linux system, to be sent to Oracle Support. The sosreport includes information about the installed rpm versions, syslog, network configuration, mounted filesystems, disk partition details, loaded kernel modules and status of all services.
VMPinfo3 - use to gather messages, logs and other data for Exalytics OVM environmentsVMPinfo3 is a tool for capturing messages, xend logs, dmesg, ovs-agent logs and other information from Oracle VM 3.x Manager and Servers. It uses the Oracle VM 3.x API to gather information about the current settings of the cluster/Server Pool. The data collected by the vmpinfo includes sosreport from all the Oracle VM Servers managed by the Oracle VM manager system where VMPinfo is being run and Oracle VM Manager log files.
Software ApplicationsRemote Diagnostic Agent (RDA) - use to collect product versions, log files and configuration for OBIEE and TimesTen on ExalyticsRemote Diagnostic Agent (RDA) is a command-line diagnostic tool that is executed by an engine written in the Perl programming language. Refer to following MOS Note on running RDA on Exalytics:
OBIEE Diagnostics - use to collect configuration, log and debug information for OBIEE problems on Exalytics
Enterprise Performance Management (EPM) and Essbase - use to collect and validate configuration and logs for Essbase and EPM problems on Exalytics
Times Ten
