Product Environment

The

SERVERNUM

 parameter specifies the unique value associated with this

OnLine configuration. (Values need to be unique within a machine. OnLine
database servers within a network can use the same

SERVERNUM

value.) The

name of the configuration file should reflect the value you select for

SERVERNUM

. The default value for

SERVERNUM

 is zero. The value cannot

exceed 255. (Refer to

 for more details about the role that the

SERVERNUM

 value plays in determining the shared-memory key.)

The

DBSERVERNAME

 parameter specifies the name of this OnLine database

server and is the value that is returned when the

SQL SITENAME

 or

DBSERV-

ERNAME

 function is executed. This value must be unique throughout the

network on which the host machine is running. The value of

DBSERV-

ERNAME

cannot exceed 18 characters. Valid characters are restricted to digits,

characters, and the underscore. The default value of

DBSERVERNAME

 is

ONLINE

.

The

MSGPATH

 parameter specifies the

UNIX

 pathname of the OnLine

message file. OnLine messages do not include the

DBSERVERNAME

, which

means it would be impossible for you to sort the messages from the separate
OnLine environments if more than one OnLine database server shared the
same

MSGPATH

. (Refer to

for a listing of

OnLine messages.)

The default value for

MSGPATH

 is /usr/informix/online.log. Refer to

 for more details about setting the value of

MSGPATH

.

Set your

TBCONFIG

 environment variable to the filename of the new config-

uration file. Specify only the filename, not the complete path. OnLine
assumes the file is located in the

$INFORMIXDIR

 directory. Make sure

that this change has taken effect before you proceed to the next step. (Refer to

 for more details about the role of

the TBCONFIG

 environment

variable.)
