Before Upgrading the OpenVMS VAX Operating System
5.5 Preparing the System Disk
5.5.8 Check Quotas and Limits
Use the Authorize utility (AUTHORIZE) to make sure the SYSTEM account has
sufficient quotas and limits. To check and, if necessary, modify quota and limit
values, do the following:
1. Enter the following commands:
$ SET DEFAULT SYS$SYSTEM
$ RUN AUTHORIZE
UAF> SHOW SYSTEM
AUTHORIZE displays the SYSTEM account’s quota and limit values.
2. Compare the values displayed on your screen to the following minimum
required values:
Quota or Limit Name Minimum Value
Open file quota (FILLM) 300
Buffered I/O limit (BIOLM) 18
Direct I/O limit (DIOLM) 18
AST limit (ASTLM) 24
Enqueue quota (ENQLM) 200
Buffered byte quota count (BYTLM) 32768†
†If you are using an InfoServer device to upgrade your system, increase the value of BYTLM to
33150
3. If necessary, adjust the quota and limit values in your SYSTEM account so
that they are equal to or greater than the minimum required values.
To change the value for a quota or limit, enter the MODIFY SYSTEM
command using the following format:
MODIFY SYSTEM/limit=new_value
For example:
UAF> MODIFY SYSTEM/DIOLM=18
4. Exit the Authorize utility by entering the following command:
UAF> EXIT
5. If you adjusted the values for any of the SYSTEM account quotas or limits,
log out and log back in to have the new values take effect.
5.5.9 Set System Parameters
During the upgrade procedure, the system is shut down and rebooted a number of
times. You must boot the system minimum (STARTUP_P1 set to MIN) before you
begin the upgrade (see Section 5.6). This prevents the startup of certain system
integrated products and layered products on the system during each reboot. To
set the system parameter STARTUP_P1 to MIN, enter the following commands:
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> PARAMETERS USE CURRENT
SYSMAN> PARAMETERS SET STARTUP_P1 "MIN"
SYSMAN> PARAMETERS WRITE CURRENT
SYSMAN> EXIT
