Before Upgrading the OpenVMS VAX Operating System
5.1 Cautions and Restrictions
5.1.2 DECset Version 11 Debugger
If you have the DECset Version 11 layered product installed on your system, you
must remove the @DEBUG$STARTUP.COM command from the system startup
procedure. The debugger shipped with OpenVMS VAX Version 7.3 is a superset of
the debugger that was shipped with the DECset Version 11 software. Removing
the @DEBUG$STARTUP.COM command will cause the debugger shipped with
OpenVMS VAX Version 7.3 to be the default system debugger.
To remove the @DEBUG$STARTUP.COM command before you upgrade the
operating system software, perform the following steps:
1. Log in to an account with system privileges.
2. Using the editor of your choice, open the SYS$STARTUP:SYSTARTUP_
VMS.COM file and search for the following command:
$ @DEBUG$STARTUP
Delete the command and any parameters. (The command might have an
optional parameter of either VMS or DECSET.)
3. Exit from the file, saving the change.
If you do not remove this command before you upgrade the operating system
software, you must remove it after the upgrade, and you must deassign the
logicals that were defined by DEBUG$STARTUP.COM by performing the
following steps:
1. Log in to the account that you used to perform the upgrade.
2. Enter the following commands:
$ DEASSIGN/SYSTEM DEBUG
$ DEASSIGN/SYSTEM DEBUGSHR
$ DEASSIGN/SYSTEM DEBUGUISHR
$ DEASSIGN/SYSTEM DBGTBKMSG
$ DEASSIGN/SYSTEM DBG$HELP
$ DEASSIGN/SYSTEM DBG$UIHELP
$ DEASSIGN/SYSTEM DEBUGAPPCLASS
$ DEASSIGN/SYSTEM VMSDEBUGUIL
3. Using the editor of your choice, open the SYSTARTUP_VMS.COM file and
search for the following command:
$ @DEBUG$STARTUP
Delete the command and any parameters. (The command might have an
optional parameter of either VMS or DECSET.)
4. Exit from the file, saving the change.
5.1.3 Customized Security Environment
The OpenVMS VAX Version 7.3 upgrade procedure provides new files and
directories in the directory [VMS$COMMON...]. If you had any special
protections and access control lists (ACLs) before the upgrade, you need to
reapply them to reestablish the security environment you had previously. For
more information about creating and maintaining a secure environment, refer to
the OpenVMS Guide to System Security.
