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.
| Command | Description |
|---|---|
| $ 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 /DISABLE | Unloads the OpenVMS idle loop detection software. |
Virtual tapes management
Specify mapping to tape container in the following way in the CHARON configuration file:
set <adapter name> container[<unit name>] = ".vtape" removable[<unit name>] = true |
Example:
set PKA container[600] = ".vtape" removable[600] = true |
Once it is done using the following commands it is possible to manage virtual tapes attached to CHARON:
| Command | Description | |
|---|---|---|
| $ CHARONCP SET MAGTAPE <device> /LOAD="<filename>.vtape" | Create the specified host-file (if it does not already exist) and attach it to the specified virtual tape device. Example:
| |
| $ CHARONCP SET MAGTAPE <device> /UNLOAD | Detach any file currently attached to te specified virtual tape device. Example:
|
Possible errors:
| Error | Description |
|---|---|
| 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 some tape container has been already specified in the CHARON configuratioon file use the command "CHARONCP SET MAGTAPE <device> /UNLOAD" to unload it first.

It is possible to define certain keys on the terminal keyboard for fast access to the CHARONCP functionalilty while you are in CHARONCP:
| Command | Description | |
|---|---|---|
$ CHARONCP | Defines an equivalence string and a set of attributes with a key on the terminal keyboard. You can have a set of keys defined automatically for use with the CHARONCP utility by placing DEFINE/KEY commands in the file SYS$LOGIN:CHARONCP_KEYDEFS.INI Example:
| |
| $ CHARONCP CHARONCP> SHOW KEY <key-name> | Displays key definitions created with the DEFINE/KEY command. Refer to the DCL help entry for SHOW KEY for further information. Example:
