At the end of the previous part of our
lesson, we started AutoGen.
AutoGen became necessary because of the system parameters, or SysGen
as VMS calls them, were inadequate for the installation of PI.
So we needed to increase some buffer sizes and some system
resources to accommodate the PINet node.
We elected to let
the VMSInstal kit automatically
run AutoGen. So as part of doing this, it edited
a system file called ModParams.Dat.
And then continued to run the AutoGen utility
to calculate new system parameters.
At the end of running AutoGen, you get a message
that says here that there is a log that we should take a look at before we proceed.
So without checking this log, it
may not be safe to reboot your computer.
And then I get an error,
insufficient... I do not know what that means, it may be bad.
I thought I was logged in as the system manager.
And then our VMSInstal kit fails.
That was to be expected because we had to
run SysGen. Let's take a look at
this sys$system AGen report.
So here is this log
file from the AutoGen.
And we can see here that there
is duplicate entries for MaxBuff found.
Duplicate value for default page file quota found..
And as I scroll down through this file,
we can also see that this is not based on
feedback information. For a new install of
PINet or a new install of PI on PINet,
this is an appropriate message because
we are basically changing the status quo,
so the history of how the system operated prior to this installation, will not help us
much with the way the
system is going to be operating after PINet is installed.
Virtual page count
is one of the parameters that PI needs to set. This sets the
upper limit on virtual memory for a process.
Apparently PINet is asking for 50,000 of
virtual memory.
So that should be OK.
Global pages is a parameter
that PINet was trying to set.
And the new global pages is not
allowed to be less than 62,000. So that should be
appropriate.
Global sections, PI is looking for
more global sections.
So here we can see that 420 is going to be the number that we get.
Logical names
system hash table got
increased to 512 and that's what PINet was looking for.
There is a logical name process hash table
and that got increased to 512 and
that's what PINet was looking for. There
is a process quota limit default page file quota
and PINet is looking for this to be
at least 35,000. Typically this
is set to be approximately the same as, or slightly less
than the virtual page count limit.
And MaxBuff was another parameter we were interested
in. This has been set to
20,480 and that is what we have to have as a minimum.
So that's good stuff. We see that some other
parameters here have been set or changed by the system.
And this recognizes
that there are other applications or other things that may be setting
or changing system parameters. Also that AutoGen tries
to be, I do not want to call it artificially intelligent,
but there are some rules-based
calculations that execute when AutoGen
runs. Make that as you change one resource, the corresponding
other resources that impact or are impacting
by that change are updated also.
This looks good so far. I did have
a error message about insufficient privileges
to write out a file, so I was a little bit concerned about
that. So that's something we need to check on. Otherwise it looks
like we are ready to try to reboot our computer and
continue with the installation of PINet.
