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.

CommandDescription
$ CHARONCP SET IDLE /ENABLE

Loads the OpenVMS idle loop detection software. 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 IDLE /DISABLEUnloads the OpenVMS idle loop detection software.

ErrorDescription
BADFILENAME

The 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 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 fileextension of ".vtape" and optional directory).

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