Initializes the SYSGEN work area with system parameter values and the name of the site-independent startup command procedure, overwriting existing values. The initial values of the SYSGEN work area when the utility is invoked are the active values. Specify the source for both the parameter values and the procedure name. They can be retrieved from a parameter file, the current system parameter file on disk, the active system in memory, or the default list. Format USE file-spec
1 – Parameters
file-spec The file specification of a system parameter file from which data is to be retrieved. You can use the SYSGEN command WRITE to create the parameter file. The default file type is .PAR. In place of a file specification, you can specify one of the following keywords: CURRENT Specifies that source information is to be retrieved from the current system parameter file on disk. On Alpha systems, the system parameter file is SYS$SYSTEM:ALPHAVMSSYS.PAR. On Integrity servers, the system parameter file is SYS$SYSTEM:IA64VMSSYS.PAR. ACTIVE Specifies that source information is to be retrieved from the active system in memory. DEFAULT Specifies that source information is to be retrieved from the default list. The USE DEFAULT command initializes the SYSGEN work area with parameter values that are built into SYSGEN; these values allow the operating system to boot on any standard configuration. To avoid starting all layered products on a system that is not tuned for them, possibly causing the system to hang, set the STARTUP_P1 system parameter as follows: SYSGEN> SET STARTUP_P1 "MIN"
2 – Qualifiers
None.
3 – Examples
1.SYSGEN> USE SYS$SYSTEM:SPECIAL This command uses the existing parameter file SYS$SYSTEM:SPECIAL.PAR. 2.SYSGEN> USE DEFAULT SYSGEN> SET STARTUP_P1 "MIN" The first command initializes the SYSGEN work area with default parameter values. The second command sets the STARTUP_P1 system parameter to "minimum."
