# Remote System Explorer runtime options

Some RSE runtime preferences are set using system properties. With RSE release 2.0, all new runtime preferences are set using the plugin_customization.ini method.

## System properties

The following system properties are used by RSE. Properties are set using `-DpropertyName=propertyValue` as a VM argument to the Java VM.

rse.showNewConnectionPrompt
  whether to show the New Connection prompt in RSE views by default. The value may be `true` or `false`. The default is `true`.
rse.showLocalConnection
  whether to create and show a Local connection by default when RSE starts with a new workspace. The value may be `true` or `false`. The default is `true`.

## Plugin customizations

See Customizing a product for a description of plugin preference customization.

### Core Preferences

org.eclipse.rse.core/DEFAULT_PERSISTENCE_PROVIDER
  The id of the default persistence provider. This provider is used when new profiles are created and an explicit persistence provider is not set for them. The default value is `org.eclipse.rse.persistence.MetadataPropertyFileProvider`

org.eclipse.rse.core/{systemTypeID}.systemType.enabled

  This preference allows you to disable installed system types on a product basis. Values may be true or false.

  true
    The system type is enabled. Connections of this system type may be created.
  false
    The system type is disabled. Connections of this system type may not be created. The system type will be unavailable in the user interface.

  The default value is true for each installed system type.

  The following example shows how to disable the "telnet" system type.

      org.eclipse.rse.core/org.eclipse.rse.systemtype.telnet.systemType.enabled = false

### User Interface Preferences

org.eclipse.rse.ui/MNEMONICS_POLICY

  The value is a bit field composed of or'ing the following bit flag values together to achieve the desired setting.

  bit mask - value 1
    If on, specifies whether or not to insert mnemonic indications into the current text of a label.
  bit mask - value 2
    If on, specifies to generate mnemonics of the form (X) at the end of labels for those languages matching the locale pattern. If off, then only characters from the label will be used as mnemonics.

  The default value is 3.

org.eclipse.rse.ui/APPEND_MNEMONICS_PATTERN
  The value is a regular expression that is matched against the current locale. Some products will desire to append mnemonics only for certain locales. The default pattern matches Chinese, Japanese, and Korean.
org.eclipse.rse.ui/SHOW_EMPTY_LISTS
  Allows a product to customize whether or not to show empty list messages in the remote system view when expanding a filter that results in an empty list of resources. The default value is `true`.
