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

This allows CHARON to detect when the emulated CPU(s) are idle and use the host power saving instructions to reduce power usage.

...

$ CHARONCP SET MAGTAPEMKA600: /UNLOAD


Possible errorDescription
BADFILENAMEThe filename specified as a value to the qualifier /LOAD was either too long or does not have a file extension of ".vtape".
DEVNOTDISM

Attempting to execute a SET MAGTAPE/LOAD command when a file is already attached.

Perform a SET MAGTAPE/UNLOAD first. If a SET MAGTAPE/LOAD command has not previously been executed then the CHARON configuration container specification for the tape device may contain a full path. Doing this will create and attach and initial tape container file. To avoid this, remove the file name from the specification (leaving only a file extension of ".vtape" and optional directory).

(info) If some tape container has been already specified in the CHARON configuration file, use the command "CHARONCP SET MAGTAPE <device> /UNLOAD" to unload it first.
