OldZU5

Specify whether to clear global vectors when switching namespace.

Synopsis

[Miscellaneous]    OldZU5=n

n is either 1 (true) or 0 (false). The default value is 0.

Description

When OldZU5 is enabled (n = 1), switching to the current namespace using the ZN command clears the global vector cache. When this parameter is not enabled, switching to the current namespace has no effect.

Changing This Parameter

On the Compatibility page of the Management Portal (System Administration > Configuration > Additional Settings > Compatibility), in the OldZU5 row, click Edit. Select OldZU5 to enable this setting.

Instead of using the Management Portal, you can change OldZU5 in the Config.Miscellanous class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).

To change this parameter for a single process only (as opposed to instance-wide), use the OldZU5() method of the %SYSTEM.Process class. See the class reference for details.
