The tha command invokes a graphical data analysis tool for analyzing the various Thread Analyzer experiments collected by the Collector using the collect(1) command. Thread Analyzer is a version of the Performance Analyzer customized for examining Thread Analyzer experiments.
The Collector gathers thread analysis information to create a Thread Analyzer experiment during the execution of a process. Thread Analyzer reads in such an experiment and displays any errors detected. Thread Analyzer supports data race detection and deadlock detection. For further information, see the Help in Thread Analyzer and the Thread Analyzer User's Guide in the documentation library at https://docs.oracle.com/cd/E60778_01/.
A command line utility called er_print is also available for displaying data from Thread Analyzer experiments in text form. See the er_print(1) man page.
Specify the path to the Java virtual machine (JVM) software for running Thread Analyzer. The default path is taken first by examining environment variables for a path to the JVM, in the order JDK_HOME, and then JAVA_PATH. If neither environment variable is set, the version found on your PATH is used. If none is found, /usr/java/bin/java is tried.
Specify JVM software options. Multiple -J arguments can be supplied. Note that there is no space between the -J flag and the jvm-option. Examples:
tha -J-d64 -- run the 64-bit analyzer (valid for Java 7 only) tha -J-Xmx2G -- run with maximum JVM memory of 2 GB (Default, 1 GB) tha -J-d64 -J-Xmx8G -- run the 64-bit analyzer with maximum JVM memory of 8 GB
Specify the font size to be used by Thread Analyzer.
Specify the path to the user directory in which to store user settings.
Print version information and Java runtime arguments before starting.
Print version information and exit.
Print usage information and exit.
Specify one or more experiments or groups to open. To specify more than one experiment, provide a space-separated list of experiment names, experiment group names, or both. If you specify more than one experiment, the data in the experiments is aggregated. Comparison of data is not supported for data races and deadlocks.
To start Thread Analyzer and open an experiment called test.1.er, type the following on the command line:
% tha test.1.er
If you do not specify any experiment names when invoking Thread Analyzer, the initial view is the Welcome screen. You can open experiments from the Welcome screen or by using Thread Analyzer's File menu and toolbar buttons to open experiments.
