IBM Informix OnLine Database Server Administrator’s Guide
Modify UNIX Startup and Shutdown Scripts
If your environment contains a single OnLine database server, you do not
need to explicitly set
TBCONFIG
. If the tbinit process cannot find the file
specified by
TBCONFIG
, it creates a copy of tbconfig.std, places the copy in
the file specified by
TBCONFIG
, and uses the values in that file for
initialization.
You must set
TBCONFIG
 if you changed the name of your configuration file
to something other than tbconfig, or if your environment supports two or
more OnLine database servers on the same machine. In the latter case, each
OnLine server requires a separate, unique configuration file that is stored in
$
INFORMIXDIR
/etc
. (Refer also to the discussion of multiple residency on
Since each OnLine configuration file requires a unique value for
SERVERNUM
, you might prefer to name each file so that it can easily be
related to a specific value. For example, the file tbconfig3 could indicate that
this configuration file specifies the unique
SERVERNUM
 of 3.
Set the
TBCONFIG
 environment variable as follows:
Modify UNIX Startup and Shutdown Scripts
You can modify your
UNIX
 startup file to initialize OnLine automatically
when your machine enters multiuser mode. You can also modify your
UNIX
shutdown file to shut down OnLine in a controlled manner whenever
UNIX
shuts down.
C shell:
setenv TBCONFIG config_filename
Bourne shell:
TBCONFIG=config_filename
export TBCONFIG
