Introduction

In this article, we will discuss the OSWatcher Black Box tool, a utility that helps diagnose Oracle Rack-related failures. Originally introduced as OSWatcher, Oracle renamed it to avoid confusion with other tools of the same name. OSWatcher Black Box is certified to run on platforms like AX Solaris, HP-UX, and Linux. Additionally, it is compatible with Windows, where a separate download is available.

Alongside OSWatcher Black Box, there is also an analyzing utility called OSWatcher Black Box Analyzer. This tool analyzes the data collected by OSWatcher and provides a graphical representation of system performance, enabling troubleshooting of rack failure issues. It is important to note that OSWatcher is not a replacement for Oracle’s built-in tools like AWR or ADM utilities, which are specifically designed for performance analysis of Oracle instances.

Downloading the Utility

To download OSWatcher Black Box, you need to log in to your Metallica account and search for the ID “30137.1”. Alternatively, you can check the OSWatcher Black Box user guide, which includes a download link. If you prefer, you can send an email to “[email protected]” to receive the utility via email.

Installation and Configuration

To begin the installation process, download the OSWatcher utility and copy the files to your rack server. Follow these steps to install and configure OSWatcher Black Box:

  1. Extract the downloaded tar file using the command tar -xvf [filename].
  2. Navigate to the created directory using the command cd [directory].
  3. Start OSWatcher Black Box by running the command startoswbb.sh.
  4. Configure the desired intervals for data collection by specifying the time in seconds. For example, startoswbb.sh 60 10 would collect data every 60 seconds for a duration of 10 hours.
  5. To run OSWatcher in the background, use the nohup command followed by the start command and the desired intervals. For instance, nohup startoswbb.sh 60 10 &.
  6. To stop OSWatcher, use the command stoposw.

Understanding the Collected Data

Once OSWatcher is running, it collects data at the specified intervals. The collected data is organized into various directories, each representing different aspects of system performance. Let’s explore some of the directories:

  • mpstat: Contains information related to CPU utilization.
  • iostat: Captures disk utilization details.
  • vmstat: Provides insight into virtual memory statistics.
  • netstat: Offers network-related information.

Within each directory, you’ll find files capturing data at different timestamps. These files can be analyzed for deeper insights into system performance. OSWatcher presents the collected data in a visually appealing format, making it easier to interpret and troubleshoot issues.

Analyzing the Data with OSWatcher Black Box Analyzer

To further analyze the collected data, you can make use of the OSWatcher Black Box Analyzer. This utility provides a graphical interface for a comprehensive view of system performance. Refer to the OSWatcher Black Box user guide for detailed information on how to use the analyzer and interpret the collected data.

Conclusion

OSWatcher Black Box is a powerful tool for diagnosing Oracle Rack-related failures. By installing and configuring this utility, you gain valuable insights into system performance. Remember to refer to the user guide for detailed instructions on installation, configuration, and data analysis. With OSWatcher Black Box on your side, troubleshooting rack failure issues becomes much more manageable.
