SSM Option 4 – Define Environment Settings

This option allows you to create and update Environments; that is, combinations of settings that change the way in which Reality functions. For example, you might create an Environment to emulate a different type of MultiValue system or for backwards compatibility with an earlier version of Reality. The environments you create can be applied at TCL when needed with the SET-ENVIRONMENT command, or associated with user profiles so that each user is given a suitable profile at log on (see SSM Option 2 - Define User Profiles).

Several predefined environments are provided, which you can use either directly or as templates for creating your own Environments.

Environment Configuration Screen

When you choose option 4 from the main SSM menu, you see the following screen:

               E N V I R O N M E N T   C O N F I G U R A T I O N
--------------------------------------------------------------------------------

Enter environment id.
(or 'CR' to exit, '?' for list, or 'D' for default)

At the prompt, enter one of the following:

• The name of an Environment to define or update (20 characters maximum).
• ?  to list the defined Environments.
• D  to update the default Environment (DEFAULT).
• Press RETURN to return to the SSM screen.

When you have selected an Environment (as above), the screen lists the associated settings:

• If you have specified an existing Environment, SSM reads the settings from the appropriate item in the ENVIRONMENT file.

• If you specify an Environment which is not on file, SSM prompts as follows:

  'Environment' is a new ID.
  :
  Enter an existing ID to use as a template; (CR) for DEFAULT; EX to exit;
  To create a Q-pointered environment, enter '>'

  Enter one of the following:

  • The name of an item to use as a template. This can save you having to enter much of the Environment information.
  • Press RETURN. The Environment held in the DEFAULT item is displayed or, if the DEFAULT item has been deleted, a system default profile.
  • ?  to list the defined Environments.
  • >  to create Q-pointered environment; that is, an alias for an existing environment. You are prompted to enter the id of the required environment.

The following is an example of the screen displayed for the new Environment called MYENV. The parameters displayed are the default settings derived from the DEFAULT Environment.

Environment Settings

To change the settings for selected Environment, enter one of the following:

• The number of an option to change. The options listed depend on which page is displayed and only the numbers of the displayed options are accepted. When you press return, the name, full description and current value of the option are displayed.
• P  to display the previous page of options, if any.
• N  to display the previous page of options, if any.
• FI  to save the environment settings.
• FD  to delete the selected environment.
• The name of an environment with which to compare your settings. The option settings from the environment you specify will be shown in the Compare with/value column.
• EX  to exit without saving your changes.

Changing the Selected Option

For the majority of environment options, there are three possible settings: N, Y  or *. When you select an option, the current value is shown on the right-hand side of the screen on the same line as the option name. To change the value, simply enter the required value, as follows:

N  Disable the option.

Y  Enable the option.

*  Don't care – use the value that is currently set.

If you press RETURN without entering a value, the option is not changed.

Some options accept different values to those above. In this case, you will be prompted to enter one of the appropriate values. For example, if you select option 1 (DOT/Stacker), you will be prompted:

Select stack type

1) REALITY 2) D3 3) MVENTERPRISE 4) MVBASE

Enter 1, 2, 3  or 4  as required.

The available options are described in the topic Environment Options.
