			   VAX/VMS VERSION 4.0











	MULTIPLE SYSTEMS ON SINGLE DISK

		- logical names

		- directory tree
	

	TAILORED SYSTEMS
	
		- What is a tailored system?

		- Installation commands








	MULTIPLE SYSTEMS ON A SINGLE DISK

		- the disk must be cluster-available on HSC

		- up to 4 nodes in a VAXCluster may share a
		  single system disk

		- all files distributed with VMS shared between
		  nodes, except:

			o PAGEFILE.SYS
			o SWAPFILE.SYS
			o SYSDUMP.DMP
			o VAXVMSSYS.PAR

		- maintenance updates only need be applied once per disk

		- recommend for use on large disk only





	[V4COMMON.] directory

		- created on system disk during installation

		- contains all the files to be shared

		- all other common subdirectories are created using:

		  SET FILE/ENTER=[SYSx]SYSCOMMON.DIR V4COMMON.DIR

		- [V4COMMON.SYSEXE] <===> [SYSx.SYSCOMMON.SYSEXE]

	SHARING SYS.EXE

 		- new parameter file:  VAXVMSSYS.PAR

		- file is located in SYS$SPECIFIC:[SYSEXE]

		- two new SYSGEN parameters:

			o USESYSPARAMS

			o WRITESYSPARAMS





	TAILORED SYSTEMS

		- lets you customize operating system
		  for specific applications

		- library disk supports the system disk

		- provides additional space on system disk for
		  user files and optional software

		- before V4.0 used for VAX-11/730 dual-RL02
		  disk drive configurations
	
		- in V4.0, supported for all system disk smaller
		  than 140000 blocks




	FILE GROUPS IN A TAILORED SYSTEM

		- operating system files are grouped to accommodate
		  tailoring the system for various tasks

		- DIGITAL supplied groups

			o REQUIRED
			o DECNET
			o DEVELOP
			o FILETOOLS
			o HELP
			o LIBRARY
			o MANAGER
			o MISCTOOLS
			o QUEUES
			o TEXTTOOLS
			o UETP
			o BLISSREQ
			o EXAMPLES
	
		- user created groups

		- VMSINSTAL required to install layered products
		  in either of these two environments
