MCR SYSMAN CONFIGURATION — VMS 5.4-3

SET
Additional information available:
CLUSTER_AUTHORIZATION
Modifies security data in a local area cluster.
Requires SYSPRV privilege.

Qualifiers
Additional information available:
/GROUP_NUMBER
/GROUP_NUMBER=[n]
Specifies the cluster group number that is recorded in
SYS$SYSTEM:CLUSTER_AUTHORIZE.DAT. A group number uniquely
identifies each local area cluster configuration on a single
Ethernet. This number must be in the range from 1 to 4095 or 61440
to 65535.
/PASSWORD
/PASSWORD=password
Specifies a password for cluster access. A password consists
of 1 to 31 characters, including alphanumeric characters, the
dollar sign, and underscore. A password provides a second level
of validation to ensure the integrity of individual clusters on
the same Ethernet that accidentally use identical group numbers. A
password also prevents an intruder who discovers the group number
from joining the cluster.
Example
SYSMAN> SET ENVIRONMENT/CLUSTER/NODE=ASCONA
SYSMAN> SET PROFILE /PRIVILEGE=SYSPRV
SYSMAN> CONFIGURATION SET CLUSTER_AUTHORIZATION/PASSWORD=GILLIAN
%SYSMAN-I-CAFOLDGROUP, existing group will not be changed
%SYSMAN-I-GRPNOCHG, Group number not changed
SYSMAN-I-CAFREBOOT, cluster authorization file updated.
The entire cluster should be rebooted.
The CONFIGURATION SET CLUSTER_AUTHORIZATION command in this
example sequence modifies the cluster password. Note that
the environment is defined to be a cluster, and the SYSPRV
privilege is established before entering the CONFIGURATION SET
CLUSTER_AUTHORIZATION command.
TIME
Modifies the current system time.
Requires LOG_IO privilege, and, in a cluster environment, SYSLCK
privilege.
Format
CONFIGURATION SET TIME [time]
Additional information available:
Example
SYSMAN> SET ENVIRONMENT/NODE=(ASCONA,LUGANO,LUCERN)
SYSMAN> SET PROFILE /PRIVILEGE=LOG_IO
SYSMAN> CONFIGURATION SET TIME 12:38:00
The CONFIGURATION SET command in this example sequence modifies
the system time on nodes ASCONA, LUGANO, and LUCERN.
SHOW
Additional information available:
CLUSTER_AUTHORIZATION
Displays the group number and multicast address of a local area
cluster.
Requires SYSPRV privilege.
Format
CONFIGURATION
SHOW CLUSTER_AUTHORIZATION
Additional information available:
Qualifier
Additional information available:
/OUTPUT
/OUTPUT[=filespec]
Redirects output from SYS$OUTPUT to the specified file. If no file
specification is provided, SYSMAN writes the output to SYSMAN.LIS
in the current directory.
Example
SYSMAN> SET ENVIRONMENT/CLUSTER/NODE=ZENITH
.
.
.
SYSMAN> SET PROFILE /PRIVILEGE=SYSPRV
SYSMAN> CONFIGURATION SHOW CLUSTER_AUTHORIZATION
Node ZENITH: Cluster group number 65240
Multicast address: AB-00-04-01-F2-FF
The CONFIGURATION SHOW CLUSTER_AUTHORIZATION command in this
example displays the group number and multicast address of node
ZENITH. Because the group number and password on other nodes in
the cluster are identical, no further information is displayed.
TIME
Displays the current date and system time to the hundredths of a
second.
Format
CONFIGURATION SHOW TIME

Qualifier
Additional information available:
/OUTPUT
/OUTPUT[=filespec]
Redirects output from SYS$OUTPUT to the specified file. If no file
specification is provided, SYSMAN writes the output to SYSMAN.LIS
in the current directory.
Example
SYSMAN> SET ENVIRONMENT/CLUSTER/NODE=ZENITH
.
.
.
SYSMAN> CONFIGURATION SHOW TIME
System time on node ZENITH: 19-APR-1990 13:32:19.45
System time on node HOSTA: 19-APR-1990 13:32:27.79
System time on node KEBBI: 19-APR-1990 13:32:58.66
The CONFIGURATION SHOW TIME command in this example displays
the system time for all nodes in the cluster.
