Hi Netlanders, I recently go a message on my uVAX/GPX that the pagefile was badly fragmented, continuing. The orange manuals say to install another pagefile. Ugg. I have two installed alread using almost 130000 blks. Is this message meaningful?? What can/should i do about it? The machine seems to be working fine. Thanks Al Saganich Saganich%frodo.decent@mghccc.harvard.edu ------

Check and make sure that you also have enough SWAPFILE space. If VMS doesn't have enough swapfile space, it will swap into the pagefile. The allocation mechanisms for swap and paging space are rather different, however, and they don't mix well (which is why there are two separate files to begin with); swapping into the page file will, indeed fragment it. Another possibility to look at (though unlikely): If you have SAVEDUMP set but no dump file, VMS will dump into the page file. The space it uses for the dump will be unavailable for paging until released (by a COPY or RELEASE (I'm not certain if this last is the name of a command, or a qualifier) in ANALY/CRASH). You can tell really quickly if there's a dump in your page file by trying to do an ANALY/CRASH on the file - it should tell you there is no valid dump in the file. I'm skeptical about this last explanation because 130000 blocks is a very large for a MicroVAX - even a full 16meg crash dump could only chew up about 33000 blocks. I have a VS II with 10 meg and a very large PAGFILQUO and VIRTUALPAGECNT values, and I've made my page file much larger than AUTOGEN recommends - but even so I'm only using 22992 blocks, plus 10400 for a swap file. (Of course, if you create huge UIS display lists, you can chew up page file space very quickly.) -- Jerry -------
