Current Checkout Order

Displays the list of product families along with their current checkout order and UseNext settings.

Family

Lists the names of the product license families. For example, Schematic, Layout, Layout Option, ADE, AMSenv, VIVA, and EAD_DATASET.

To change the checkout order of a product family, click and drag the required tier up or down to move it to the desired location.

UseNext

Displays the UseNext setting, which controls whether to check out the next available license for Virtuoso tier-based applications when the license required for a requested application is not available.

If a tiered application has an associated UseNext setting, a drop-down list appears next to its name. If you reorder a tier within the product family, the UseNext drop-down moves along with it.

The UseNext drop-down list provides the following options:

• prompt: Confirm before checking out a higher-tier license.
• always: Always check out the higher-tier license (as per selected checkout order).
• never: Never check out the higher-tier license and display an error message instead.

When prompt is set as the UseNext drop-down value and the license for a requested application is not available, the Next License dialog box displays, which lets you check out a higher tier license, subject to availability. Four options are offered: Session, Skip, Always, or Never.

• Session: Checks out a higher-tier license, if available, for the current session. If a higher-tier license is unavailable, the Next License dialog box will only be displayed once. However, a new virtuoso session will cause the dialog box to display again.
  The Session option does not override the setting in the local .cdsenv file and updates only the internal or in-memory value of the corresponding UseNextLicense .cdsenv variable. Because of this, the Session response is applicable for the current session only. However, if you want to restore the Next License dialog box settings in the same session, reset the UseNextLicense .cdsenv variable to prompt using the envSetVal function in the CIW or select prompt from the UseNext drop-down list.
• Skip: Skips the next license. For example, if L license is not available, and you click Skip in the Next License dialog box, the XL license will be skipped and an attempt to check out the GXL license will be made.
• Always: Virtuoso will always try to check out the next license, if the requested license is not available. The Next License dialog box is not displayed again when virtuoso is restarted.
• Never: Virtuoso will never try to check out the next license, if the requested license is not available. The Next License dialog box is not displayed again when virtuoso is restarted.
  The Always and Never options are stored in the following environment variables in ~/.cdsenv as soon as they are set.

For example:

license VLSXL_UseNextLicense string "prompt"/"always"/"never"
license VSEL_UseNextLicense string "prompt"/"always"/"never"

If a license is not available warning messages will be displayed in the CIW.

The settings selected in the Current Checkout Order pane are reflected in the .cdsenv variables CheckoutOrder and UseNextLicense.

Available Tiers

Displays all applicable tiers for each product family. However, you can choose to deselect a tier and remove it from the current checkout order list by dragging and moving it to Available Tiers.

If there is only one tier in the family tree, you are not allowed to remove it from the Current Checkout Order list by dragging and moving it to Available Tiers list, because a family tree cannot be empty.

Tier

List of available and applicable tiers in the right pane.

UseNext

Displays the value of the tier.

Save to File

Saves the selected options in the .cdsenv file. You can also edit your preferences in the.cdsenv file.
