	I am probably re-inventing the wheel, but I have discovered a
convenient way to install software upgrades without shutting down normal
operations and with minimal inconvenience to the users.  
	Prior to running VMSINSTAL I disable GROUP and WORLD privileges
to the layered product and to the HELP library, if needed.  Then I run
VMSINSTAL and after verifying the installation, reestablish WORLD privi-
leges.  Below is an example of the sequence of commands needed to install
DATATRIEVE upgrade.  I put them into two command procedures to be used
when needed.

$! Datatrieve installation
$set proc/priv=all
$set uic [1,4]
$run sys$system:dmu
set protection/grant=all/uic=[system]/position=1 cdd$top
exit
$set proc/priv=nobypass
$set prot=(s:rwed,o:rwed,g,w)/log sys$sysroot:[sysexe]dtr*.exe
$set prot=(s:rwed,o:rwed,g,w)/log sys$common:[syshlp]helplib.hlb
$! end

	run the DATATRIEVE installation

$! restore WORLD privileges
$set proc/priv=all
$set uic [1,4]
$run sys$system:dmu
delete/protection/position=1 cdd$top
exit
$set proc/priv=nobypass
$set prot=(s:rwed,o:rwed,g:re,w:re)/log sys$sysroot:[sysexe]dtr*.exe
$set prot=(s:rwed,o:rwed,g:re,w:re)/log sys$common:[syshlp]helplib.hlb
$! end
