10.1 Using iManager to Configure the Java Environment Parameters

  1. Click to display the Identity Manager Administration page.

  2. Open the properties for the driver set whose parameters you want to configure:

    1. In the Administration list, click Identity Manager Overview.

    2. If the driver set is not listed on the Driver Sets tab, use the Search In field to search for and display the driver set.

    3. Click the driver set to open the Driver Set Overview page.

    4. Click the Driver Set menu, then click Edit Driver Set properties.

  3. Click Misc to display the property page that contains the Java environment parameters.

  4. Modify the following settings as desired:

    Classpath Additions: Specify additional paths for the JVM to search for package (.jar) and class (.class) files. Using this parameter is the same as using the java -classpath command. When entering multiple class paths, separate them with a semicolon (;) for a Windows JVM and a colon (:) for a UNIX/Linux JVM.

    JVM Options: Specify additional options to use with the JVM. Refer to your JVM documentation for valid options.

    DHOST_JVM_OPTIONS is the corresponding environment variable. It specifies the arguments for JVM 1.2. For example:

    -Xnoagent -Xdebug -Xrunjdwp: transport=dt_socket,server=y, address=8000

    Each option string is separated by whitespace. If an option string contains whitespace, then it must be enclosed in double quotes.

    The driver set attribute option has precedence over the DHOST_JVM_OPTIONS environment variable. This environment variable is tacked on to the end of driver set attribute option.

    Initial Heap Size: Specify the initial (minimum) heap size available to the JVM. Increasing the initial heap size can improve startup time and throughput performance. Use a numeric value followed by G, M, or K. If no letter size is specified, the size defaults to bytes. Using this parameter is the same as using the java -Xms command.

    DHOST_JVM_INITIAL_HEAP is the corresponding environment variable. It specifies the initial JVM heap size in decimal number of bytes. It has precedence over the driver set attribute option.

    Refer to your JVM documentation for information about the JVM's default initial heap size.

    Maximum Heap Size: Specify the maximum heap size available to the JVM. Use a numeric value followed by G, M, or K. If no letter size is specified, the size defaults to bytes. Using this parameter is the same as using the java -Xmx command.

    DHOST_JVM_MAX_HEAP is the corresponding environment variable. It specifies the maximum JVM heap size in decimal number of bytes. It has precedence over the driver set attribute option.

    Refer to your JVM documentation for information about the JVM's default maximum heap size.
