How to Set Up Multiple Residency
How to Set Up Multiple Residency
Thissection describes the six-step installation procedure for multiple OnLine
database servers on the same host machine. Before you perform this
procedure,you already should have installed one OnLine database server as
described inChapter 1, “Installation and Initial Configuration.” Chapter 1
contains background information that is useful for understanding this
section.
To install multiple residency
1. Log in as user informix. Copy $INFORMIXDIR/etc/tbconfig.std to a
new configuration filename.
2. Editthe new configuration file with an operating-system editor and
modifythe four parameters that are critical to multiple residency. Do
not useDB-Monitor.
3. Set your TBCONFIG environment variable to the new name of the
configuration file.
4. (Optional)Use DB-Monitor to finish tuning the configuration for the
new OnLine database server.
5. Access DB-Monitor and initialize disk space for this independent
OnLine database server.
6. Ensure that all OnLine users have set theirTBCONFIG environment
variable to reflect the correct OnLine database server environment.

Step 1: Create a New Configuration File

Thetbconfig.std file is provided as a template for use in setting up additional
OnLine database servers. (Refer to page1-11 for more details about OnLine
configuration files.) The new file that you create must also reside in the
$INFORMIXDIR/etc directory. Name the file in such a way that it is easily
associatedwith the SERVERNUM value contained therein, as well as with its
function.For example, you might select the filename tbconPROD3 to indicate
aproduction environment configuration file with the SERVERNUM value of 3.
