1-56 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 setTBCONFIG. If the tbinit process cannot find the file
specified by TBCONFIG, it creates a copy oftbconfig.std, places the copy in
the file specified by TBCONFIG, and uses the values in that file for
initialization.
You must setTBCONFIG if you changed the name of your configuration file
to something other thantbconfig , or if your environment supports two or
more OnLine database servers on the same machine. In the latter case, each
OnLineserver requires a separate, unique configuration file that is stored in
$INFORMIXDIR/etc. (Refer also to the discussion of multiple residency on
page 9-7.)
Since each OnLine configuration file requires a unique value for
SERVERNUM, you might prefer to name each file so that it can easily be
relatedto 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 ScriptsYou can modify yourUNIX startup file to initialize OnLine automatically
whenyour machine enters multiuser mode. You can also modify your UNIX
shutdownfile 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
