Troubleshooting
While working with HCL OneTest™ API, you might encounter some problems that you can easily troubleshoot.
- Troubleshooting: Installation and configuration
  You can troubleshoot some of the problems that you might encounter when you are installing, configuring, or running HCL OneTest™ API.
- Global problem notifications
  Problems can occur at a time when HCL OneTest™ API cannot display an error message. Instead, a warning icon is displayed. Double-clicking the icon reveals a list of errors.
- Working with HCL OneTest™ API logs
  To configure the HCL OneTest™ API logs, including those for the RunTest command when run from the command line, update the HCL OneTest API logging properties file.
- Working with HCL OneTest™ API Agent logs
  To configure the HCL OneTest™ API Agent logs, including those for the RunTests command when run from the command line, update the HCL OneTest API Agent logging properties file.
- Working with RQMAgent logs
  To configure the RQMAgent logs, update the RQMAgent logging properties file.
- Locating the logging properties files
  When you install HCL OneTest™ API, HCL OneTest API Agent, or HCL® Quality Server including the HTTP/TCP proxy, several logging properties files are added to each installation's home directory.
- Logging references
  You can use the following list of logging-related information to help you find information about the logs that are supported by HCL OneTest™ API. All of the programs use the Java logging framework. For details, see the Java logging framework documentation.
- Debugging failed Windows™ services
  If one of the programs fails to start as a Windows™ service, it can be difficult to determine the cause. Typically the service fails to start but gives no indication of why. The Windows Event log has nothing useful and the process might not have created its log file.
- Troubleshooting: Installation and configuration
  You can troubleshoot some of the problems that you might encounter when you are installing, configuring, or running HCL OneTest™ API.

- Troubleshooting: Testing on IBM® z/OS®
  You can use workarounds to common problems that you might encounter when you use IBM® z/OS® with HCL OneTest™ API.

Troubleshooting: Java™ applications that use JDBC

You can use workarounds to problems that you might encounter when you test Java™ applications in HCL OneTest™ API.

Table 1. Troubleshooting testing with Java™ applications that use JDBC
Problem	Description	Solution
When you use the integration tester JDBC driver alongside the Oracle ojdbc8 driver and the following error message is displayed: `java.lang.IllegalStateException: Timer already cancelled`	The integration tester JDBC can cause other JDBC drivers to re-register with the JDBC DriverManager. This causes problems for the ojdbc8 driver.	In the application that uses JDBC, you must specify the following JVM argument when you run the application: `-Dcom.greenhat.jdbc.configure.driver.manager=false`
