<p>I think you're right, but it has been <u>decades</u> since I
last used Tops-10. At WPI, we had a KA-10 running a much modified
6.03 series monitor that we were quite proud of. At Marlboro, the
project that I was working on (FILE-FINDER, a database for DUMPER
tapes) was quite Tops-20 centric; we depended on files with holes
in them.</p>
<p>I'm unaware of any systems level structured data store in either
Tops-10 or Tops-20 with the exception of the Quasar failsoft file
(QSRFSS, holds queue, print, batch requests across crashes). I
don't find this surprising; if you crash and corrupt a file with
confuration information in it, a flat ASCII file is whaaay easier
to recover than an specially engineered database. The binary
accounting and error files are sequential and don't count, IMHO.<br>
</p>
<div class="moz-cite-prefix">Under Tops-20, we used the following
'trick' for start-up speed and persisted configuration. The
configuration file was 'compiled' into binary and directly mapped
into memory on start-up.</div>
<div class="moz-cite-prefix">
<ol>
<li>This was necessary for LPTSPL as it is started up for jobs,
but shut down and put into a quiescent state when there is
nothing left to print. When you have a lot of printers,
reparsing LPFORM.INI can be a real dog. Very noticeable.<br>
</li>
<li>I got the idea from the mailer, which does the same thing
for mailing-list.txt</li>
<li>The EXEC will also do it; you can restore a binary
environment with all your special scripts really fast (like on
PUSH or LOGIN)</li>
<li>I had been thinking about doing this for the Extended Mode
FTP server, but I'm not sure it's worth it. I instrumented
the start up time and it's in the milliseconds. Probably
would be necessary for a couple hundred simultaneous small
requests.</li>
</ol>
<p>If I ever get truly serious about supporting Galaxy again, then
probably I'll bite the bullet and put up Tops-10 so I can
validate execution.<br>

I've never used Tops-10 as an operator, so I can't answer most of
this, but one question I think I can...
<br>
<br>
My understanding is that neither Tops-10, nor TOPS-20 have a
persistent database. Instead you need to have a script that does
all the definitions, and you need to run it at every boot. But I
could be confused about that one.

KLH-10 TOPS-10 noob questions:
<br>
<br>
1) At the TOPS-10 boot startup option prompt, I can type in
CHANGE and then set the DECnet address. How do I make it persist
across reboots and not have to do this every time?
