### Misc

The Misc page lets you configure trace settings and Java environment settings for the driver set.

### Trace Settings

Using the trace settings, you can enable driver-related events to be viewed through the DS Trace utility. Any trace settings you configure for the driver set apply to all drivers in the set. If you only want to trace one driver, you should configure the trace settings on the driver. In addition, you should only trace events in order to test driver configurations or troubleshoot driver issues. Tracing events for a driver can cause the Metadirectory server to process events slowly.

For information about how to use the DS Trace utility, see the Identity Manager 3.6 Common Driver Administration Guide.

> #### Trace Level

> The Metadirectory engine supports the following trace levels:

> - Trace level 0: Displays fatal messages, errors, warnings and successes.
> - Trace level 1: Displays informational messages in addition to the information from Trace level 0.
> - Trace level 2: Displays contents of XML documents in addition to the information from Trace level 1.
> - Trace level 3: Displays policy information in addition to the information from Trace level 2.

> Individual drivers might support additional trace levels. Refer to the Identity Manager driver documentation for details.

> #### XSL Trace Level

> DS Trace displays XSL events. Set this trace level only when troubleshooting XSL style sheets. If you do not want to see XSL information, set the level to 0.

> #### Java Debug Port

> Allows developers to attach a Java debugger.

> #### Trace File

> When a value is set in this field, all Java information for the driver is written to file. The value for this field is the path for that file.

> As long as a file is specified, Java information is written to the file. If you do not need to debug Java, leave this field blank.

> #### Trace File Encoding

> The trace file uses the system's default encoding. You can specify another encoding if desired.

> #### Trace File Size Limit

> Sets a limit for the trace file. Select Unlimited to allow the file to grow to fill the disk.

### Java Environment Parameters

Use these parameters to configure the Java virtual machine (JVM) on the Metadirectory server associated with the driver set. The parameters apply only if the driver set is associated with Metadirectory server that is version 3.6 or newer.

> #### Classpath Additions

> Specifies 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

> Specifies additional options to use with the JVM. Refer to your JVM documentation for valid options.

> #### Initial Heap Size

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

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

> #### Maximum Heap Size

> Specifies the maximum heap size available to the JVM. Specify a numeric value followed by G, M, or K (case-sensitive). If no letter size is specified, the size defaults to bytes. Using this parameter is the same as using the Java -Xmx command.

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