MCR SYSMAN CONFIGURATION — VMS 5.1-B
The CONFIGURATION command is used to inspect and modify various parameters controlling the software configuration and execution of the running system or cluster. Format: CONFIGURATION [subcommand] [parameter] [value or qualifier]
Additional information available:
SET
The CONFIGURATION subcommand SET modifies the value of a parameter. Its function is dependent on the particular parameter.
Additional information available:
CLUSTER_AUTHORIZATION
The CLUSTER_AUTHORIZATION parameter updates records in SYS$SYSTEM: CLUSTER_AUTHORIZE.DAT. The file is created if it does not exist. Format: CONFIGURATION SET CLUSTER_AUTHORIZATION
Additional information available:
Parameter qualifiers
Additional information available:
/GROUP_NUMBER
/GROUP_NUMBER=n This specifies the Cluster group number. It must be in the range of 1-4095 and 61440-65535. If omitted, the group number is not changed. If SYS$SYSTEM:CLUSTER_AUTHORIZE.DAT does not exist, the group number must be specified. SYSPRV and OPER privileges are required on each of the selected nodes. Use the SET PROFILE/PRIV=(SYSPRV,OPER) command to set these privileges. Requires appropriate file access privilege to SYS$SYSTEM:CLUSTER_AUTHORIZE.DAT.
/PASSWORD
/PASSWORD=password
This specifies the password for cluster access. It must be from
1 to 31 characters in length, and must be composed of
alphanumeric characters, dollar signs, and underscores. If the
password value is omitted, the password is not changed. If
SYS$SYSTEM:CLUSTER_AUTHORIZE.DAT does not exist, a password must
be supplied. SYSPRV and OPER privileges are required on each of
the selected nodes. To set these privileges use the command
SET PROFILE/PRIV=(SYSPRV,OPER).
4 Examples
1. SYSMAN> CONFIGURE SET CLUSTER_AUTHORIZATION/PASSWORD=trigger -
_SYSMAN> /GROUP_NUMBER=64464
This command will set the cluster password for the currently
selected cluster to "TRIGGER" and modify the GROUP NUMBER of
the currently selected cluster to the value 64464.
TIME
The TIME parameter is used to update the system time. Format: CONFIGURATION SET TIME [time] If "time" is not specified, the interval system clock is automatically reset according to the time-of-year clock. LOG_IO, SYSLCK, and OPER privileges are required for this command. Use the SET PROFILE/PRIV=(LOG_IO,SYSLCK,OPER) command to set these privileges.

timeRestrictionsCluster-wide timeExamples
time
A date-time value in the format: [dd-mmm-yyyy[:]] [hh:mm:ss.cc] The hyphens, colons, and period are required delimiters. Delimit the date and time, when both are specified, with a colon.
Additional information available:
time-date format information
A date in the format: DAY-MONTH-YEAR, or a time in the format: HOUR:MINUTE:SECOND.HUNDREDTH, or both. DAY an integer in the range 1 through 31. MONTH JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC. YEAR an integer in the range 1858 through 9999. HOUR an integer in the range 0 through 23. MINUTE an integer in the range 0 through 59. SECOND an integer in the range 0 through 59. HUNDREDTH an integer in the range 0 through 99.
Restrictions
Note that the time-of-year clock is optional for some processors. For further information about the time-of-year clock, see the VAX Hardware handbook.
Cluster-wide time
If the SYSMAN environment is /CLUSTER, then special processing is employed to insure that all processors in the cluster are set to the same time: Due to communications and processing delays, the command cannot synchronize clocks exactly; the variation is typically less than a few hundredths of a second. If the command cannot verify that the time was set to within one half second of the specified time, you receive a warning message that names the node which failed to respond quickly enough. As a result of slight inaccuracies in each interval clock, times on various members of a VAXcluster tend to drift apart. See the examples section for a command procedure that can automatically synchronize system times in a VAXcluster.
Examples
1. $ SYNCH_CLOCKS:
$ RUN SYS$SYSTEM:SYSMAN
set environment/cluster
configuration set time
exit
$ WAIT 6:00:00
$ GOTO SYNCH_CLOCKS
This procedure sets the time on all VAXcluster nodes to
the value obtained from the local time-of-year clock,
waits 6 hours, then resets the time for the cluster again.
2. SYSMAN> CONFIGURATION SET TIME 08:00:00.00
This command will set the time on the selected nodes to
8:00AM.
SHOW
The CONFIGURATION SHOW subcommand displays the value of a parameter. Its function is dependent on the parameter. format: CONFIGURATION SHOW parameter

Command qualifiers
Additional information available:
/OUTPUT
/OUTPUT[=file-spec] Specifies that the output from the execution of this command is to written to the file specified, or to "[default_directory]SYSMAN.LIS" if no filespec is given.
CLUSTER_AUTHORIZATION
Displays the group number of the cluster authorization file for all systems in the environment. If the environment is CLUSTER, then only the first node's group is displayed, and warning messages are given for nodes in the cluster whose group numbers and/or passwords are different.
TIME
Displays the current system time.
Examples
1. SYSMAN> CONFIGURATION SHOW TIME
System time on node LONDON: 11-OCT-1987 20:01:32.22
System time on node ROME: 11-OCT-1987 20:01:31.42
System time on node PARIS: 11-OCT-1987 20:01:31.33
SYSMAN>
This command displays the time on each of the selected nodes.
2. SYSMAN> CONFIGURATION SHOW CLUSTER_AUTHORIZATION
Node LONDON: Cluster group number 64664
SYSMAN>
This command lists the cluster group number of the first node
to respond. If any of the other nodes has a different Cluster
group number, a warning message is displayed.
