In the Linux and UNIX environments, there is no ODBC Administrator or Driver Manager. To configure an ODBC data source name (DSN) definition for DataDirect, you must edit the required system information, which is held in a plain text file called .odbc.ini (note that the name of this file starts with a period).
Set the ODBCINI environment
variable to point to the file, specifying a full path and file name. If you do not set this variable, the path defaults
to $MQSI_REGISTRY/odbc/.odbc.ini for a 32-bit execution group,
which is created when WebSphere Message Broker is installed. The
file must have file permissions of mqm:mqbrkrs.
A sample template is provided in the file install_dir/merant/odbc.ini which
contains examples of how to configure a DSN residing in each of the databases
supported by WebSphere Message Broker
The example stanzas
for the supported platforms are displayed below. The examples show the recommended
configuration for the supported databases.
The entries in the stanzas that you must configure to match your local requirements are shown in italics (descriptions of these entries are provided in Editing the .odbc.ini parameters). You must retain all the entries shown, but you can remove a complete stanza if you do not require it for your configuration (for example, if you are using an Oracle database, you can remove the stanzas shown for DB2 and Sybase).
Ensure that the appropriate library search path environment
variable is set to reflect the database products to be used. For example,
the variable is LD_LIBRARY_PATH on Solaris and Linux
(x86 platform).
Refer to your database product documentation for more details.
If
you are using Linux (zSeries
platform) or Linux (POWER platform), you do not need to define an
ODBC connection. Instead, the data source name used in the message flow is
the same as the DB2 alias of the database.
If you have a 64-bit database package installed,
or have created 64-bit execution groups:
This addition might prevent you from running DB2 commands such as db2create from the command line in this environment shell. If you want to enter DB2 commands, start a separate environment shell and run db2profile for the relevant database instance, but do not run mqsiprofile.
If you are using WebSphere MQ Version 6, refer to the section 'Implications
of a 64-bit queue manager' in the WebSphere
MQ Quick
Beginnings book for your operating environment.
On AIX, if you are using DB2 as your database, a maximum of 10 connections using shared memory are allowed from a single process. This means that if you deploy more than one or two message flows at the same time, you might see connection failures characterized by the DB2 error message SQL1224N. The connection errors are reported in the system log from the broker's execution group. To avoid this problem, you can use TCP/IP mode to connect to DB2. For detailed instructions on how to do this, see DB2 error message SQL1224N is issued when you connect to DB2.

You have now configured your 32-bit ODBC data source names on UNIX. Next, you must configure the environment for issuing console commands, and for running the broker, so that it can access the required database libraries. For more information, see Setting your environment to access databases.
