Slow CMS operations on fast CHARON-VAX host
Problem
CMS ("Code Management System") may appear very slow in guest OS (VMS) on certain fast CHARON-VAX hosts. A process running CMS places itself into hibernation for unknown reason, and wakes up once a second. This regular hibernation makes the CMS utility very slow. Reason for hibernation is not clear and appears to be a "feature" of CMS.
Solution
To workaround this problem a special utility "FRCWAK" ("FoRCed WAKeup") has been developed by Stromasys. It wakes up the process running CMS 10 times a second. Which effectively reduces total time the process stays in hibernation, and makes the CMS utility moving faster.
To apply the workaround:
Download containing a disk image with "FRCWAK" utility executable.
Unzip the archive.
Mount this disk image under host OS (VMS) and copy the utility to "sys$sysdevice:[frcwak]" folder.
Use it in the following way:
In certain situations the provided executable of "FRCWAK" utility has to be re-compiled. Use its for that (this source code is also available on the utility's disk image - see above):
