Setting Historical Server start-up parameters
22
Historical Server
-l logFile Path name of the log file in which information and error messages
about the Historical Server are logged. The data collected includes
start-up information, error messages, and possibly a record of
alarms that were triggered. The default path name is hs.log in the
current directory.
-U
userName Name of Historical Server superuser. When the superuser logs in to
Historical Server, that user is allowed to issue the
shutdown
command to terminate Historical Server, and to view or delete any
data files created by Historical Server, regardless of the user who
initiated the recording sessions.
This user name is not required to correspond to either an Adaptive
Server login account or to an operating system registration. See
“The Historical Server superuser account” on page 11 for more
information.
If you do not specify this parameter, any user may stop Historical
Server, but no user has unrestricted access to the Historical Server
data files.
-P password Password of user specified with the -U parameter. A user who logs
in to Historical Server must supply this username and password to
exercise Historical Server superuser privileges. See “The Historical
Server superuser account” on page 11 for more information.
Note
If you specify the
-U
parameter on UNIX platforms, but do
not specify this parameter, Historical Server prompts for a
password during start-up. However, Historical Server must be
started in foreground mode for you to receive the prompt. Make the
following changes to the start-up script to be prompted for a
password:
• Remove the
-P
parameter and the ampersand (&) from the
start-up script file.
• Execute the script file.
• When prompted for a password, enter the password for the
username
you specified in the
-U
parameter.
• Put the Historical Server process in the background.
-n
maxConnections Specifies the maximum number of concurrent Open Client
connections allowed to Historical Server. Valid values are 1 through
20. The default is 20.
Open Client connections to Historical Server are
isql
connections.
