CHAPTER 2 Configuring Historical Server
User’s Guide
21
Table 2-1: Historical Server start-up parameters
Parameter Description
-D
homeDir Required. This parameter specifies the home directory for this
instance of Historical Server. The account that starts Historical
Server must have read, write, and search (execute) permissions on
the Historical Server home directory.
The default home directory is the current working directory for the
account that starts Historical Server.
The control file used by this instance of Historical Server resides in
the home directory. The control file contains information about past
recording sessions and is updated during the current run as new
recording sessions are established.
The directory specified by this parameter is also the default
directory into which historical data files are written during a
recording session. The user who creates a recording session can
override this default location without affecting the definition of the
control file.
Multiple instances of Historical Server can share the same home
directory. See “Configuring multiple instances of Historical
Server” on page 23 for more information.
Note If any UNIX shell-specific characters, such as the C shell’s
tilde (~), appear at the start of the directory’s name, you must
separate the
-D parameter and the directory name by one or more
space characters. Otherwise, the shell cannot recognize that file
name expansion is required.
-d
delim Specify a default file delimiter for the view files that Historical
Server generates. Delim can be:
• A character. For example:
./histserver -d ‘ ‘
or
./histserver -d/
• an escaped character. For example: ./histserver -d’/t’
• A four digit hexadecimal number representing the ascii code of
the delimiter. For example:
./histserver -d0x09
-i interfacesFile
(Upper or lower
case “i” is valid
after the dash.)
Path name of the interfaces file to use. The file must contain
connection information, including the correct names, for Historical
Server and all Adaptive Server and Monitor Server pairs to which
you want this Historical Server to connect. If you omit this
parameter, the name and location of the default interfaces file is:
UNIX: $SYBASE/interfaces
NT: SYBASE\sql.ini (where SYBASE is the value of the SYBASE
environment variable)
