Installation and Initial Configuration

The value of

SQLEXEC

 directs the front-end processes to a specific database

server within the

directory. The default value for

SQLEXEC

is

, the OnLine database server. If OnLine is the

only database server in your $

 directory, you do not need to

define

SQLEXEC

.

If you worked with an

IBM I

nformix

SE

database server on this machine in the

past, you might have an

SQLEXEC

 environment variable already set for use

with

SE

. If you are not planning to maintain the

SE

database server but intend

to run only OnLine on this machine, you might need to modify

SQLEXEC

 to

ensure that it now reflects the OnLine database server.

If you intend to maintain both an

SE

database server and an OnLine database

server on the same machine, ensure that all users have their

SQLEXEC

variable properly set. (The pathname of the

SE

 database server is

.)

Set the

SQLEXEC

 environment variable as follows:

The

TBCONFIG

 environment variable performs two tasks:

■

Directs the tbinit process to the OnLine configuration file that is to
be read for initialization values

■

Directs the OnLine server process (sqlturbo) to the correct OnLine
shared-memory space

The

TBCONFIG

 value is not a full pathname; therefore, all OnLine configu-

ration files must reside in the directory $

.
