SAS Companion for the OpenVMS Operating Environment

System Start-up

Job type All jobs.

User System manager.

Usage The OpenVMS Install facility can be used to make core SAS images resident in memory.

Benefit Elapsed time of system start-up may decrease as much as 30 percent when running the SAS System under X-windows and by 40 percent in other modes.

Cost With Version 8 of the SAS System, installing all images listed in the sample commands consumes between 7500 and 1200 global pages and 6 to 8 global sections. Refer to the list below for the difference in cost for VAX and AlphaVMS.

Installing SAS System images can decrease the elapsed time of SAS System start-up by up to 40 percent. Installing images is most effective on systems where two or more users are using SAS simultaneously. Use the following commands in the system start-up file to install the core set of SAS images:

$ @SASdisk:[SAS8.TOOLS]SAS8_SYSTEM.COM
$ INSTALL :== $SYS$SYSTEM:INSTALL/COMMAND"
$ INSTALL ADD SAS$ROOT:[IMAGE]SAS8.EXE/OPEN/SHARE
$ INSTALL ADD SAS$ROOT:[PROCS]SASBXSPH.EXE/OPEN/SHARED
$ INSTALL ADD SAS$ROOT:[PROCS]SASSDS.EXE/OPEN/SHARED
$ INSTALL ADD SAS$ROOT:[PROCS]SASMOTIF.EXE/OPEN/SHARED
$ INSTALL ADD SAS$ROOT:[PROCS]SASMSG.EXE/OPEN/SHARED

SASdisk is the disk containing the SAS System; SAS$ROOT is the directory of the SAS System.

The Install facility can be used to make core SAS images resident in the memory. Elapsed time of system start-up may decrease by as much as 30 percent when running the SAS System under X-windows, and by 40 percent in other modes. With Version 8 of the SAS System, installing the images listed in the sample commands consumes the following resources:

VAX

SAS8.EXE	3 global sections and 1246 global pages
SASBXSPH.EXE	1 global section and 3028 global pages
SASDS.EXE	1 global section and 74 global pages
SASMOTIF.EXE	1 global section and 3274 global pages

AlphaVMS

SAS8.EXE	2 global sections and 1680 global pages
SASBXSPH.EXE	2 global sections and 5168 global pages
SASDS.EXE	2 global sections and 112 global pages
SASMOTIF.EXE	2 global sections and 4320 global pages
