Knowing the start-up flags/parameters

There are some flags that you can set to alter the launching behavior of the IDE. These are set as the command-line options for the shortcut that is used to launch the IDE.

JDeveloper is a multiuser-enabled IDE that allows multiple users to share the same workstation. By default, the IDE configuration files are saved in a directory within the user's working directory. The following are the start-up flags/parameters:

• -J-Dide.user.dir=<system_directory>: Using this property, you can override the default behavior to write the configuration files into the specific directory of choice.

  Tip

  An alternate way for this is to set the JDEV_USER_DIR environment variable that points to the user's current working directory.

  JDEV_USER_HOME and JDEV_USER_DIR are the variables that are listed in the MW_HOME/jdeveloper/jdev/bin/jdev.boot file. JDeveloper will look up these variables on startup to set the user's directory. For example:

  set JDEV_USER_HOME=C:\Users\vtkrishn\AppData\Roaming\JDeveloper

  set JDEV_USER_DIR=C:\JDeveloper\mywork

• nonag: This will disable all dialogs or messages displayed while starting the IDE. However, the splash screen will still be displayed to the user. Use nosplash to disable the splash screen.

• noreopen: This option will not reopen the files that were opened in the previous user session.

  Note

  The noreopen option will help JDeveloper to start faster, with there being no open files from the previous user session. All these settings will be displayed in the Properties tab of the IDE in Help | About. You may find other useful information in this section.
