Starting Up and Shutting Down the System
4.1 Understanding Booting and System Startup
2. A short time later (up to a few minutes), the system displays a message
similar to the following message:
The OpenVMS system is now executing the site-specific system startup commands.
This message indicates that the system is executing SYSTARTUP_VMS.COM.
You can modify this file to perform various operations at startup time. For
more information, see Section 5.2.7.
3. Finally, the procedure displays informational messages and accounting
information. For example:
%SET-I-INTSET, login interactive limit=64, current interactive value = 0
19-APR-2000 15:00:00.00
SYSTEM job terminated at 19-APR-2000 15:00:00.00
Accounting information:
Buffered I/O count: 133 Peak working set size: 401
Direct I/O count: 12 Peak pagefile size: 2379
Page faults: 325 Mounted volumes: 0
Charged CPU time: 0 00:00:55.23 Elapsed time: 0 00:01:31.24
After the system displays this information, you can log in.
4.2 Booting with Modified System Parameter Values
Using a conversational boot, you can modify system parameter values as follows:
Task

Information
Boot after showing or modifying individual system parameter values Section 4.2.1
Boot with an alternate system parameter file Section 4.2.2
Boot with default values for system parameters Section 4.4.1
Before using a conversational boot to show or modify system parameter values,
you must be familiar with the following terms:
Term Definition
Active values System parameter values stored in memory and used by the active
system.
Current values System parameter values stored in the default parameter file.
When the system boots, it sets active values for system parameters
using the current values.
†On VAX systems, the default system parameter file is
SYS$SYSTEM:VAXVMSSYS.PAR.
‡On Alpha systems, the default system parameter file is
SYS$SYSTEM:ALPHAVMSSYS.PAR.
Default values System parameter values stored in the default list and used by
default.
†VAX specific
‡Alpha specific
