General

Use the General tab to specify most of the information that is required to run commands on distributed hosts, and to save command  specification that you create for later use.  DCEM allows you to create, save, and edit command specifications, which reduces your time and effort when you repeatedly  run the same command. A command specification consists of the following parts: You can find more detailed help on the following elements of this window:

Name

The name that identifies a command specification. When you create a new command specification, you must type a name for it in this field. The name field is not required for running a command specification, but is required when saving a specification.   When you want to run an existing command specification, you can either use the Browse... button next to the Name field to select a saved command specification name for this field or you can type the command specification name in the field.
 


Browse...

Opens the Browse Command Specification dialog, which displays a list of existing command specifications. You can select a command specification from the list to work with it in this dialog. The selected command specification causes the DCEM to initialize the input fields with specified command data.
 


Path

The path that points to the actual location of the saved commands. The default value for this field is $PATH. You  can edit this field.  If you use the the default $PATH in this field, the application does not delegate the local $PATH to the target hosts  when the command is run. Instead, it prepends export PATH=$PATH to the command, where the $PATH variable referred to is the one set on the target machine.

To run commands found only in a specific directory, you can replace $PATH with that directory name. To guarantee that a directory is searched first, you can prepend the directory to $PATH, for example, /usr/bin:$PATH.

If you leave the Path field empty, it is the same as having $PATH.



Command

Displays the command or script to run. You can either type the command directly, or retrieve a saved command specification to fill this field with the saved value.



Run as User

Displays the user name under which the command specification will be run.  By default, it is populated with the user name under  which DCEM is running. You can edit this field. Target machines must be configured to allow the user or machine under which DCEM is running to run as the user specified in this field. This configuration is specific to the remote shell used to run a command.



Description

An optional text description of the command specification.  This description also displays in the Browse Command Specifications dialog to help you locate a particular saved command specification.


Host Names

The name of one or more hosts.  You can type the name of any fully qualified host name, as long as the host has a remote shell available, or type a list of fully qualified host names separated by commas or spaces.


Browse...

Opens the Browse Hosts dialog, which displays a list of hosts in the Cluster System Management domain. You can select one or more hosts from the list, which places them in the Host names field on this dialog. Use the Groups tab of this dialog to define groups of hosts.


Groups of Hosts

The name of one or more host groups. You can type a list of host groups separated by  commas or spaces. You can also select host group names from the Browse Groups dialog, which displays when you click on the Browse button next to the field. To use this selection dialog, you must first have created the groups of hosts.


Browse...

Opens the Browse Groups dialog, which displays a list of previously defined groups of hosts. You can select a group from the list to work with.
