HI!
I'm running a Compiler under a virtualed VMS 4.5 (yep) hosted on a UNIX system.
When we fire up the system in February, one of our biggest compile projects was taking 2.5 hours to compile
a great upscale from our original VAXStation II, It was taking 4 days then...)
The problem, is, that it is slightly increasing over time.
Now we are at 6 hours compiling time..(v/s 2.5 in fe
no code were change in the compile task
I did re-installed the February VMS image and the compile is down to 3-4 hrs.. (Still not our original 2.5h)
I cannot reload the UNIX host system nor do I have access to it
I'm suspecting that it is a combine issues (UNIX and VMS) but cannot put the finger on it.
Anybody have idea?
VMS swapfile, dump, ?
UNIX swapfile?
UNIX defrag?

RE: sys slower and slower: Is something building up over time
if restarting the emulator (SIMH, I assume) or the OpenVMS system itself didn't help, the 'problem' might be on the disks (container files ?) used by the emulated system. They could have been fragmented and causing the disk-IOs to become slower. You could run MONI FCP and check for Window Turn Rate. If this seems to be the problem, defragmentation needs to be run from OpenVMS (probabaly a BACKUP/IMAGE and restore).
On OpenVMS, problems are NOT being solved by re-installing the operating system. We leave this 'troubleshooting method' to other operating systems...
Consider to record the resource usage of your compiles (CPU, DIRIO, BUFIO, Pagefaults, elapsed time) using IMAGE accounting or batch job accounting. If compiles then take longer, compare the various resources being used.
