Functional Details

This module tells the Data Explorer executive to run an internal system command. In the user interface, it is available only through the Execute Script Command option of the Options pull-down menu of the Message window. And with the exception of the "print" command, it should be invoked only through the scripting language.

command

is the executive command to be executed.

value

is a command-dependent value.

The types of commands executed by the Executive module fall into four categories:

Printing System Information

The following list summarizes the kinds of system information available with the "print" command.

Distributed Processing in Script Language

Use the following commands to control distributed processing in the script language. (In the user interface, distributed processing should be controlled through the Execution Group Assignment... option of the Connections pull-down menu in the VPE window. See 9.1 , "Using Distributed Computation" in IBM Visualization Data Explorer User's Guide.)

Note: These Executive calls must be followed by $sync, as shown.

Module Definition

To load the module definition file (mdf) of an outboard module after Data Explorer has been started, use the script syntax shown here. (In the user interface, use the Load Module Description(s)... option of the File pull-down menu in the VPE or Image window.)

Executive("mdf file", "mdf_filename");
$sync

Note: The call to load the mdf file must be followed by $sync, as shown.

UserInteractor Definition
To load a UserInteractor after Data Explorer has been started, use the following script syntax:
Executive("loadinteractors", "userinteractor_filename");
$sync

Note: In the User Interface this can be done using the Execute Script Command option in the Commands menu of the Message Window.

System Functions

The following commands execute system functions:

Example

In this example, the execution groups "mine" and "yours" are attached to hosts "ours" and "theirs" respectively. Also, Data Explorer is started with a memory allocation of 50MB on the host "theirs."

Executive("group attach",{"mine:ours","yours:theirs -memory 50"});
