Once the installation is completed, add the following line to the "SYS$STARTUP:SYSTARTUP_VMS.COM" ("SYS$STARTUP:SYSTARTUP_V5.COM" for VMS 5.5) file for the package to be loaded automatically at system startup:

After that the package will be loaded automatically on startup.

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
