  After installing new memory (or any hardware really) you should use
autogen to reconfigure your system.  The processes has been discribed in
detail both in the SMOG (System Manger Operations Guide - VMS manual set 10)
and several issues of the Pageswaper (the VMS publication from DECUS).

  Set your default to sys$system.

  Save any changes you have made to PARAMS.DAT in a file called PARAMS.LOC.
  Type

$ @sys$update:autogen config
$ @sys$update:autogen params

  Put your local changes from PARAMS.LOC back into PARAMS.DAT after verifing
  that you still want them (a wsmax of 300 on a 4MB 730 is not valid for
instance).  Then type

$ @sys$update:autogen

  Finally to put all of these changes into the system type (I believe)

$ @sys$update:autogen reboot

  To reboot the system.  If this doesn't work you may have to

$ mcr sysgen
SYSGEN> use sys$system:autogen.par
SYSGEN> write current
SYSGEN> ^Z
$ @sys$system:shutdown

  And so on to reboot the sytem with the new parameters.

  Autogen computes the 'right' parameters for you system based on your
configuration.  In general it knows more than you do, so don't change
the parameters in params.dat unless you REALLY understand what they do
and mean.  And NEVER reconfigure your system without using autogen as
changing some parameters will completely distroy your system unless you
also change related parameters.  The parameters are documented in the SMOG.

  Of course I change the dynamic system parameters on the fly so take
the last tirade with a grain of salt.  I do, however, always consult the
SMOG before doing anything.
