Preparing to Use OpenVMS Management Station
G.1 Preparing Your OpenVMS System
G.1.1 Setting Up in a Mixed-Architecture Cluster Environment
The OpenVMS Management Station server creates several configuration files:
• TNT$UADB.DAT
• TNT$ACS.DAT
• TNT$JOURNAL.TNT$TRANSACTION_JOURNAL
• TNT$MONITOR.DAT
• TNT$MONITOR.TNT$MONITOR_JOURNAL
• TNT$EMERGENCY_MOUNT.COM
In a common-environment cluster with one common system disk, you use a
common copy of each of these files located in the SYS$COMMON:[SYSEXE]
directory on the common system disk, or on a disk that is mounted by all cluster
nodes. No further action is required.
However, to prepare a common user environment for an OpenVMS Cluster system
that includes more than one common VAX system disk or more than one common
Alpha system disk, you must coordinate the files on those disks.
The following rules apply:
• Disks holding common resources must be mounted early in the system startup
procedure, such as in the SYLOGICALS.COM procedure.
• You must ensure that the disks are mounted with each cluster reboot.
Follow these steps to coordinate files:
1. Decide where to locate the files. In a cluster with multiple system disks,
system management is much easier if the common system files are located on
a single disk that is not a system disk.
2. Copy TNT$UADB.DAT, TNT$ACS.DAT, TNT$MONITOR.DAT,
TNT$MONITOR.TNT$MONITOR_JOURNAL, TNT$EMERGENCY_
MOUNT.COM, and TNT$JOURNAL.TNT$TRANSACTION_JOURNAL to
a location other than the system disk.
3. Edit the file SYS$COMMON:[SYSMGR]SYLOGICALS.COM on each system
disk and define logical names that specify the location of the cluster common
files.
Example
If the files will be located on $1$DJA16, define logical names as follows:
$ DEFINE/SYSTEM/EXEC TNT$ACS -
_$ $1$DJA16:[VMS$COMMON.SYSEXE]TNT$ACS.DAT
TNT$EMERGENCY_MOUNT.COM will be created in SYS$SYSTEM or in the
directory pointed to by the TNT$ACS logical, if the logical exists.
$ DEFINE/SYSTEM/EXEC TNT$UADB -
_$ $1$DJA16:[VMS$COMMON.SYSEXE]TNT$UADB.DAT
$ DEFINE/SYSTEM/EXEC TNT$JOURNAL -
_$ $1$DJA16:[VMS$COMMON.SYSEXE]TNT$JOURNAL.TNT$TRANSACTION_JOURNAL
$ DEFINE/SYSTEM/EXEC TNT$MONITOR -
_$ $1$DJA16:[VMS$COMMON.SYSEXE]TNT$MONITOR.DAT
$ DEFINE/SYSTEM/EXEC TNT$MONITORJOURNAL -
_$ $1$DJA16:[VMS$COMMON.SYSEXE]TNT$MONITOR.TNT$MONITOR_JOURNAL
