27 Using the IdcCommand Utility to Access Content Server

This chapter describes how to use the IdcCommand utility to access Oracle WebCenter Content Server services from other applications.

This chapter includes the following sections:

27.1 About the IdcCommand Utility

The IdcCommand utility is a standalone Java application that executes Content Server services. Almost any action you can perform from the Content Server browser interface or administration applets can be executed from IdcCommand.

The program reads a command file, which contains service commands and parameters, and then calls the specified services. A log file can record the time that the call was executed, whether the service was successfully executed, and if there were execution errors.


The IdcCommand utility returns only information about the success or failure of the command. To retrieve information from Content Server in an interactive session, use the Java COM wrapper IdcCommandX, available on Microsoft Windows platforms.

To run the IdcCommand utility, you must specify the following parameters on the command line or in the intradoc.cfg configuration file:

  • A command file containing the service commands and parameters
  • A Content Server user name for a user who has permission to execute the services being called
  • A path and file name for a log file
  • The connection mode (auto, server, or standalone)

Certain commands that cannot be executed in standalone mode. In general, the server performs these commands asynchronously in a background thread. This happens in the update or rebuild of the search index.

For information about using services in custom components, see Getting Started with Content Server Components, and Using Services in Oracle Fusion Middleware Services Reference for Oracle WebCenter Content.

27.2 Setting Up IdcCommand

To set up IdcCommand, you must specify the following:

  1. A command file, which specifies the services to be executed and any service parameters.

    For more information, see Specifying a Command File.

  2. Configuration options, which specify the command file and other IdcCommand information. You can set IdcCommand configuration options in two places:

    1. IdcCommand Options in a Configuration File. For more information, see {Example - Idc Command Options in a Config file}.

    2. On the command line, specifying option flag when running IdcCommand, as shown in {Example - IdcCommand Options on the Command Line}.

      For more information, see Specifying Configuration Options.

Example 27-1 IdcCommand Options in a Configuration File


Example 27-2 IdcCommand Options on the Command Line

-f newfile.hda -u admin -l C:/domain/newlog.txt -c server

27.2.1 Specifying a Command File

The command file defines the service commands and parameters that are executed by the IdcCommand utility. Command files must follow rules for syntax, precedence, and special tags and characters. Command File Syntax

The command file uses the HDA (hyperdata file) syntax to define service commands.

  • Each service to be executed, along with its parameters, is specified in a @Properties LocalData section.
  • For some services, an @ResultSet section is used to specify additional information.
  • Data from one section of the command file is not carried over to the next section. Each section must contain a complete set of data for the command.
  • Service names and parameters are case sensitive.

The following example shows a command file that executes the ADD_USER service and defines attributes for two new users.

Example 27-3 Command File for the ADD_USER Service

<?hda version="5.1.1 (build011203)" jcharset=Cp1252 encoding=iso-8859-1?>
# Add users
@Properties LocalData

dFullName=Jennifer Smith
@ResultSet UserAttribInfo
@Properties LocalData
dFullName=Peter Wallek  
@ResultSet UserAttribInfo
<<EOD>> Precedence

IdcCommand uses precedence to resolve conflicts among the name/value pairs within the LocalData section of the command file. When normal name/value pairs are parsed, they are assumed to be within the @Properties LocalData tag. If the section contains HDA tags, the normal name/value pairs take precedence over name/value pairs within the @Properties LocalData tag.

For example, if foo=x is in a normal name/value pair and foo=y is within the @Properties LocalData tag, the name/value pair foo=x takes precedence because it is outside the tag. Special Tags and Characters

These special tags and characters can be used in a command file.

Special Character Description


Each section of the command file must specify the name of the service it is calling.


The end of data marker. The command file can include one or more sections separated with an end of data marker. For an example, see Command File Syntax.


The pound character placed at the beginning of a line indicates that the line is a comment.


The backslash is an escape character.

@Include filename

This tag enables you to include content from another file at the spot where the @Include tag is placed. This tag can be used to include a complete HDA file or to include shared name/value pairs. This inclusion takes the exact content of the specified file and places it in the location of the @Include tag. A file can be included as many times as desired and an included file may include other files. However, circular inclusions are not allowed.

27.2.2 Specifying Configuration Options

To run the IdcCommand utility, specify the following parameters on the command line or in the DomainHome/ucm/cs/bin/intradoc.cfg configuration file.

Parameter Required? Command Line Syntax Configuration File Syntax

Command File


-f name.txt



-u sysadmin

Log File


-l C:/logs/log.txt

Connection Mode


-c auto


Command-line configuration options override the settings in the configuration file. Command File

You must specify the name of the command file that contains the service commands and parameters. The command file parameter can specify a full path (such as C:/command_files/command.txt), or it can specify a relative path. For more information, see Specifying a Command File. User

You must specify a Content Server user name. This user must have permission to execute the services being called. Log File

You can specify a path and file name for an IdcCommand log file. As each command is executed, a message is sent to the log file, which records the time the command was executed and its success or failure status. If the log file already exists, it is overwritten with the new message. The log file can be used to display processing information to the user.

  • If the action performed is successful, a "success" message is written to the log file.

  • If the action performed is not successful, an error message is written to the log file.

  • If no log file is specified, information is logged only to the screen. Connection Mode

You can specify the connection mode for executing the IdcCommand services.

Connection Mode Description


IdcCommand attempts to connect to the Content Server instance. If this fails, services are executed in standalone mode.

This is the default connection mode.


IdcCommand executes services only through Content Server.


IdcCommand executes services in a standalone session.

Certain services cannot be executed in standalone mode. In general, these services are performed asynchronously by the server in a background thread. For example, this happens during an update or rebuild of the search index.

27.3 Running IdcCommand

To run IdcCommand:

  1. Create a new IdcCommand working directory.

    Use this directory for your command file and configuration file.

  2. Create a command file in the working directory to specify the desired service commands.
  3. Copy the intradoc.cfg configuration file from the DomainHome/ucm/cs/bin directory into the working directory.


    Do not delete the IntradocDir or WebBrowserPath information.

  4. Add IdcCommand options to the intradoc.cfg file in the working directory, as {Example - IdcCommand Options in intradoc.cfg File} shows.

    For more information, see Specifying Configuration Options.

  5. Run the IdcCommand utility from the DomainHome/ucm/cs/bin directory:

Example 27-4 IdcCommand Options in the intradoc.cfg File


27.4 Using the Launcher

The Launcher is a native C++ application used to manage services in Windows environments and to construct command line arguments and environment settings for the Java VM.

The main operation of the Launcher is to find and read its configuration files, compute any special values, then launch an executable with a command line that it constructs. Configuration files support Bourne Shell-like substitutions, all of which start with the dollar sign ($) followed by an alphanumeric identifier or expression inside braces ({}).

The Launcher executable is installed in the following directory:


On UNIX systems, symlinks are created in the bin directory to Launcher.sh, a Bourne Shell wrapper that executes the Launcher executable. The purpose of this wrapper is to locate the correct binary Launcher executable for the platform. The term Launcher is used here to refer to the native Launcher executable or to the Launcher.sh Bourne Shell script.

The Launcher or the symlink to Launcher.sh must reside in a directory with a valid intradoc.cfg configuration file and must have the same name as the Java class file to be launched (case sensitive). The Launcher uses this name to set the environment variable STARTUP_CLASS.

On Windows this name is computed by calling GetModuleFileName(). On UNIX systems, it is computed by inspecting argv[0]. The PLATFORM variable is set to the Content Server identifier for the platform. The variable BIN_DIR is set to the directory where the Launcher is located.

The Launcher reads a file named intradoc.cfg from BIN_DIR. This file should contain a value for IntradocDir. The IntradocDir directory is used as the base directory for resolving relative paths. Any unqualified path in this document should be taken as relative to the IntradocDir. Future releases of Content Server may change or remove these variable names.

If the intradoc.cfg file does not contain a value for IdcResourcesDir, the Launcher sets IdcResourcesDir to $IntradocDir/resources. If the Launcher is starting a Windows service, it sets IS_SERVICE to 1. If it is unset, the Launcher also sets PATH_SEPARATOR to the correct character for the platform.

The Launcher reads the intradoc.cfg file first to find the locations of configuration files, then reads all available configuration files in this order:

  1. $IdcResourcesDir/core/config/launcher.cfg
  2. $BIN_DIR/../config/config.cfg
  3. $IntradocDir/config/config.cfg
  4. $IntradocDir/config/config-$PLATFORM.cfg
  5. $IntradocDir/config/state.cfg
  6. $IdcResourcesDir/core/config/launcher-$PLATFORM.cfg
  7. $BIN_DIR/intradoc.cfg
  8. $BIN_DIR/intradoc-$PLATFORM.cfg
  9. All files specified on the command line, using the -cfg option.


    You can assign variable values directly on the command line by using the -cfg option NAME=VALUE.

27.4.1 Quotation Rules

The Launcher uses Bourne Shell-like quotation rules. A string can be inside double quotation marks (") to escape spaces. A backslash (\) can precede any character to provide that character. After a final command line is computed, the Launcher separates it into spaces without quotation marks. Each string is then used without quotation marks as an entry in the argv array for the command.

27.4.2 Computed Settings

After reading the configuration files, the Launcher processes variable substitutions. Some variables can have extra computations to validate directories or files, build command-line argument lists, or construct PATH-like variables.

These special computations are performed for variables based on their type. To set a type for a variable, set TYPE_variable_name=typename in any of the configuration files listed previously.

The following list describes Launcher variable types:

  • file
    file Launcher Variables

    This type looks for a file. If the value of variable_name is a path to an existing file, it is kept. If not, every variable beginning with variable_name_ is checked. The last value, which is a path to an existing file, is used for the new value of variable_name.

    In this example PASSWD_FILE is set to /etc/master if /etc/master.passwd exists, or it is set to /etc/passwd</span> if /etc/passwd exists. Otherwise, PASSWD_FILE is undefined.

  • directory
    directory Launcher Variables

    In this example, JDK is set to the same value as the last of the JDK_ variables that is a directory. Typically, this would point at the JDK installed with Oracle Fusion Middleware. Note that JDK_java_home references $JAVA_HOME; if a variable is not defined in any configuration file but is in the environment, the environment value is used.

  • executable
    executable Launcher Variables

    The executable type looks for an executable. It works very much like the file type, but looks through every directory in $PATH for each candidate value. In this example JAVA_EXE is set to the Java executable in the JDK if it exists. Otherwise it is set to the first Java executable in the PATH.

  • list

    list Launcher Variables

    The list type computes a list of options for an executable. Each value that begins with variable_name_ becomes a quoted option, and variable_name is set to the entire list. In this example, JAVA_OPTIONS is set to the string:

    "-Didc.bin.dir=/intradocdir/bin/" "-Xmx384m"
  • path
    path Launcher Variables

    The path type computes a path-like value.The value of each variable starting with variable_name_ is appended to the value of variable_name separated by the value of PATH_SEPARATOR. In this example, BASE_JAVA_CLASSPATH is set to a very long class path.

  • lookupstring
    lookupstring Launcher Variables

    The lookupstring type uses a second parameter to construct a lookup key for the final value. The second parameter is the value of $PARAMETER_variable_name. If this value is undefined, the current value of variable_name is used as the lookup key. In this example, PARAMETER_VDK_PLATFORM has the value of ${PLATFORM}_ or ${PLATFORM}_vdk27 depending on the value of UseVdkLegacySearch.

    This value is then used to look up the value of the variable VDK_PLATFORM_${PARAMETER_VDK_PLATFORM} which is then enclosed in quotation marks and assigned to VDK_PLATFORM.

  • lookuplist
    lookuplist Launcher Variables
    STARTUP_CLASS_version=Installer --version
    STARTUP_CLASS_WebLayoutEditor=IntradocApp WebLayout
    STARTUP_CLASS_UserAdmin=IntradocApp UserAdmin
    STARTUP_CLASS_RepositoryManager=IntradocApp RepositoryManager
    STARTUP_CLASS_Archiver=IntradocApp Archiver
    STARTUP_CLASS_WorkflowAdmin=IntradocApp Workflow
    STARTUP_CLASS_ConfigurationManager=IntradocApp ConfigMan

    The lookuplist type uses a second parameter to construct a lookup key for the final value. The second parameter is the value of $PARAMETER_variable_name. If this value is undefined, the current value of variable_name is used as the lookup key.

    Unlike lookupstring, lookuplist does not enclose the final value in quotation marks. For this example, the current value of STARTUP_CLASS is version. STARTUP_CLASS is replaced with the value Installer --version.

27.4.3 Launcher Environment Variables

After processing the computed settings, the Launcher iterates over all variables that begin with the string EXPORT_. The value of each variable is used as an environment variable name, which has the value of the second half of the EXPORT_ variable assigned. For example, EXPORT_IDC_LIBRARY_PATH=LD_LIBRARY_PATH exports the value of the IDC_LIBRARY_PATH variable with the name LD_LIBRARY_PATH.

The variable JAVA_COMMAND_LINE is used to get the command line. Any command line arguments to the Launcher that have not been consumed are appended to the command line. On UNIX systems, the command line is parsed and quoting is undone and then execv is called. On Windows, a shutdown mutex is created and CreateProcess is called with the command line. Care should be taken because CreateProcess does not undo backslash-quoting.

The principal mechanism for debugging the Launcher is to add the flag -debug before any arguments for the final command. You can also create a file named $BIN_DIR/debug.log which triggers debug mode and contain the debug output.

The Launcher has knowledge of the following configuration entries, which it either sets or uses to control its behavior. Note that these configuration variables might change or be removed in future releases of Content Server:

  • IDC_SERVICE_NAME: the name of the win32 service used for service registration, unregistration, startup, and shutdown.

  • IDC_SERVICE_DISPLAY_NAME: the display name of the win32 used for service registration.

  • IntradocDir: the base directory for relative path names.

  • IdcBaseDir: an alternate name for IntradocDir.

  • IdcResourcesDir: set to $IdcHomeDir/resources if otherwise undefined.

  • IdcNativeDir: defaults to $IdcHomeDir/native if otherwise unset.

  • PATH_SEPARATOR: set to either colon (:) or semi-colon (;) if otherwise unset.

  • STARTUP_CLASS: set to the name of the Launcher executable.

  • MUTEX_NAME: the name used to create a shutdown mutex on win32.

  • BEFORE_WIN_SERVICE_START_CMD: if set, is a command line that is executed before a win32 service starts.

  • UseRedirectedOutput: if set tells the Launcher on win32 to redirect the output from the Java VM to a file.

  • ServiceStartupTimeout: the time out used for waiting for a Java process to successfully start on win32.


    By using Launcher.exe, changing the status.dat file, and altering the value of the JVM command line, you could theoretically run any Java program as a Windows service. This is not recommended for normal use, but it does explain some ways you could configure the Launcher.

27.4.4 User Interface

The UI for the Launcher is the same as the application it launches. For example, if the Launcher is renamed to IntradocApp, the following command-line arguments are specified to launch the Web Layout Editor:

IntradocApp WebLayout

This launches the Web Layout Editor as a standalone application.

By default, the application is launched without console output. However, when launching IdcServer, IdcAdmin, IdcCommandX, or the Installer, Java output is printed to the screen. In all other cases, the output is suppressed for a cleaner interface.

For some applications, such as the Batch Loader and the Repository Manager, it is desirable to view the Java output from the application. To force the Launcher to dump the Java output to the screen, use the -console flag in this manner:

IntradocApp RepMan -console

The output is now written to the console from which the Repository Manager was launched.

If the Launcher is renamed IdcServer, BatchLoader, SystemProperties, or any other Java class that requires no additional parameters, it can be launched with a simple double-click. In other cases, a shortcut can be used to launch them by double-clicking.

27.4.5 Configuring the Launcher

To use the Launcher, you must first rename the Launcher.exe file to an executable with the same name as the class file to be launched. Typical examples include IdcServer.exe and IntradocApp.exe.


If you want to make a custom application, you must create a custom directory and rename the Launcher.exe file to the service that is to be launched. A valid intradoc.cfg file must be in the same directory as the executable. The only required parameter is IntradocDir; however, you can include other entries to alter the way the Java application is launched.

27.4.6 Configuration File Example

You can modify the configuration file for the applications you need to run. The following example shows configuration file entries that are sufficient to launch nearly all Content Server applications.

Configuration File Entries for Content Server Applications
<?cfg jcharset="Cp1252"?>
#Content Server Directory Variables

Other applications, such as Oracle WebCenter Content: Inbound Refinery, require additional classes in the class path. This file can also be modified to enable Content Server to be run with different Java Virtual Machines.

The CLASSPATH is designed to look for class files in order of the listed entries. In other words, the Launcher will search the entire DomainHome/ucm/idc/native directory before it looks in the resources directory or server.zip file. This is desirable if the users want to overload Java classes without patching the ZIP file.

Additionally, the Launcher can be used to install, uninstall, and run Java applications as Windows services, if they follow the correct API for communicating back to the Launcher. For more details on how to make any Java application run as a Windows service with the Launcher, see the source code for IdcServer.java or IdcAdmin.java.

The COMPUTEDCLASSPATH is used to add class files to the CLASSPATH that the Launcher uses. To add class files, override this flag.


The intradoc.cfg file is usually altered to include the locations of JDBC drivers for particular databases upon installation. If you want to use an alternate JDBC driver, place it outside of the IdcHomeDir directory for Content Server, and alter the JDBC_JAVA_CLASSPATH_customjdbc entry in the intradoc.cfg file with the location of the driver.

The following example shows a command to run Content Server with the IBM virtual machine on a Windows operating system.

Command for Running Content Server with a Custom JVM
#customized for running the IBM VM
JAVA_EXE=full path

When using a custom JVM, specify the full path to the Java executable file to be used.


Avoid overriding the JVM command line. Customization is more complicated because of the custom class loader. If you do override the JVM command line, start with the $IdcHomeDir/resources/core/config/launcher.cfg file.

If you do so, start with the following command line:


You can set JAVA_COMMAND_LINE_SELECTION entry in the configuration file to idcclassloader or traditional.

If you choose to change which JVM you are using, and if that VM has all the standard Sun SDK JAR files, then it is better to use the J2SDK configuration entry to relocate the root directory of the SDK directory rather than use JAVA_EXE to specify the location of the Java executable. (This is not applicable for the IBM VM.)

The J2SDK variable changes the directory where the Sun SDK libraries are found (such as tools.jar). If you change this entry without setting the JAVA_EXE entry, then Java executables are assumed to be in the bin directory of the path in J2SDK. The default value for J2SDK is ...\shared\os\win32\j2sdk1.4.2_04.

To add a value to JAVA_OPTIONS, use JAVA_OPTIONS_server=-server or another similar value.

The following table describes commonly used command-line options. Those options noted with an asterisk (*) are available on a Windows operating system only. Unmarked options are available for a Windows or UNIX operating system.

Option Description
-console *   Forces the Launcher to keep a Windows console window open so that the Java output and error streams are printed to the console.
-debug Shows paths and variables in use at startup, and startup errors. Also enables Java debugging in Content Server; when repeated, this increases verbosity.
-fileDebug Similar to the -debug option but this option dumps debug data to the debug.log file. It is usually only set in JAVA_OPTIONS or JAVA_SERVICE_EXTRA_OPTIONS in the intradoc.cfg file to debug Windows services.
-install *   Used to install the Java application referred to by the Launcher as a Windows service.
-install_autostart *    Similar to the -install option but this option installs the application to start when the server starts.
-uninstall *   Used to uninstall the Java application referred to by the Launcher as a Windows service.
-remove *   Same as -uninstall.
-dependent service-name *   Makes the Windows service dependent on whether the service-name service is also running.

This command is useful when you want to make a dependent call for each service.

For example, if you want to launch a database before starting Content Server, you can specify the Content Server startup to be dependent on the database startup.

-dependent user password *   Used with -install, installs the service with the credentials of the user specified by user with password password.

This command will check the user regardless of the credentials, but may not install the service. The credentials of the user need to extend to the service for the auto-start to run the service automatically.

For certain services, such as Inbound Refinery, the last flag is required so that the service can run with higher permissions. The user name must be in the typical Microsoft format DOMAIN\User. Once users change passwords, the service will not be able to log in, and therefore will not run.

-help Provides verbose output on Launcher use.
-version Displays the version number for the Launcher and exits.
-asuser user password *   Used during an install to install a service as a specified user with a specific password.
-exec path _name Overrides the argv[0] setting. Used by Launcher.sh to specify the target path_name because the target of the symlink does not know its source.
-cfg configfilename Specifies additional config files to read before determining computed settings.
-idcServiceName servicename *   Specifies the name of the Windows service. This can used with -remove to uninstall another Content Server service without using that Content Server Launcher (for example, if an entire installation directory has been removed).


To customize the class path to alter the system path to load Oracle .dll files, you can set the path as follows:


Custom shared objects and .dll files must not be installed into IdcHomeDir.


To customize the classpath to alter the system path to load Oracle .dll files, you can change the pathway to:


If you want to load custom .dll files, you should put them in the IdcHomeDir/native/win32/lib directory.

27.5 Calling Services Remotely

To use services remotely, you must have these files on the remote system:

  • DomainHome/ucm/cs/bin/IdcCommand.exe
  • DomainHome/ucm/cs/bin/intradoc.cfg (same file as on Content Server)
  • IntradocDir/config/config.cfg

In addition, the following configuration entries must be defined in the #Additional Variables section of the config.cfg file on the remote system:

  • IntradocServerPort=4444
  • IntradocServerHostName=IP or DNS
