![]() Supported options and trace file issues are the same as for OPENJ9_JAVA_OPTIONS. Set this variable to add Java options to the end of the command line. #MAC OS LIST ENVIRONMENT VARIABLES WINDOWS#Setting this variable is equivalent to setting the property on Windows operating systems, and on other operating systems. Set this environment variable to specify the font directory. Note: The equivalent to OPENJ9_JAVA_OPTIONS, IBM_JAVA_OPTIONS is deprecated and will be removed in a future release. To avoid this problem, add %d, %p or %t to the trace file names. If you specify the name of a trace output file either directly, or indirectly, by using a properties file, the output file might be accidentally overwritten if you run utilities such as the trace formatter, dump extractor, or dump viewer.

Set this variable to store default Java options, including -X, -D, or -verbose:gc style options. This setting is not available if the VM is invoked by using JNI. Using this variable, you can find the command-line parameters set when the VM started. This variable is set by the VM after it starts. General VM environment variables are shown in the following table: Environment variable On Windows the separator is typically a semicolon ( ).On AIX, Linux, macOS, and z/OS the separator is typically a colon (:).If you are setting multiple values for an environment variable in a list: These variables are set only for the current shell or command-line session. ![]() export LOGIN_NAME=Fred (AIX/Linux/macOS: ksh or bash shells).To set the environment variable LOGIN_NAME to Fred, run: The names of environment variables are case-sensitive in AIX, Linux, macOS, and z/OS. Use values exactly as shown in the documentation. echo $ENVNAME (AIX, Linux, macOS, and z/OS).To show a particular environment variable, run: Finding and setting environment variables Note: Environment variables are overridden by command-line arguments. Use command-line arguments rather than environment variables, which are retained only for compatibility.
