Installation and Initial Configuration

LTAPESIZE

 specifies the maximum amount of data that should be written to

each tape, expressed in kilobytes. If the pathname of the tape device is
/dev/null

, the tape size is ignored. The default value of

LTAPESIZE

 is

10,240

This section describes how to assign values to the OnLine identification
parameters.

OnLine identification parameters are an issue if you are configuring more
than one OnLine database server for a single host machine or if you plan to
integrate this OnLine database server into a network of OnLine servers that
use the client/server capabilities of

IBM I

nformix

STAR

.

In either case, the database server processes require a method to uniquely
identify their associated OnLine shared memory space within

UNIX

 shared

memory. The identification key is linked to the value of the

SERVERNUM

parameter.

For a complete discussion of configuration issues affected by multiple
residency, refer to

uration issues, refer to the

uide. For more information about the

IBM I

nformix

STAR

configuration parameters in the tbconfig.std file, refer to

SERVERNUM

 specifies a unique identification number associated with this

specific occurrence of OnLine. The identifier distinguishes this OnLine server
from all other database servers in the $INFORMIXDIR directory and the
network, if one exists.

The default value of

SERVERNUM

 is 0. The value cannot exceed 255.

If OnLine and earlier database servers co-exist on the same machine, they
must have unique values for

SERVERNUM

. The

SERVERNUM

value for earlier

servers is implicitly set to 0. Therefore, OnLine requires a value that is greater
than 0.
