General Description

The "CHARON Guest Utilities for OpenVMS" (CHARONCP) package contains several utilities for managing virtual tapes, changing the emulator speed and creating useful definitions for that operations.

This set of utilities is located in the "charoncp013.vdisk" disk file in the "C:\Program Files\CHARON\Virtual Disk Images\Tape utilities package" folder.

Supported OpenVMS versions: OpenVMS 6.1 and above.

In case of OpenVMS upgrade, CHARONCP will have to be re-installed.

$ MOUNT <device name> /OVERRIDE=IDENTIFICATION

Performance optimization

CHARON takes 100% of host CPU even in case of idle state of guest OpenVMS operating system. To get rid of such resources consumption there is a specific option provided by CHARON Guest Utilities: "idle" mode.

To load the OpenVMS idle loop detection software, use:

$ CHARONCP SET IDLE /ENABLE
