To connect to IBM DB2 Universal Database for Linux, UNIX, and Windows, or
IBM Cloudscape, or Apache Derby, you must install an IBM DB2 Universal
Database client on the same computer on which you are running PHP. The
extension has been developed and tested with DB2 Version 8.2.
To connect to IBM DB2 Universal Database for z/OS or iSeries, you also
require IBM DB2 Connect or the equivalent DRDA gateway software.
Requirements on Linux or Unix
The user invoking the PHP executable or SAPI must specify the DB2 instance
before accessing these functions. You can set the name of the DB2 instance
in php.ini using the ibm_db2.instance_name
configuration option, or you can source the DB2 instance profile before
invoking the PHP executable.
If you created a DB2 instance named db2inst1 in
/home/db2inst1/, for example, you can add the
following line to php.ini:
ibm_db2.instance_name=db2inst1
If you do not set this option in
php.ini, you must issue the
following command to modify your environment variables to enable access to
DB2:
bash$ source /home/db2inst1/sqllib/db2profile
To enable your PHP-enabled Web server to access these functions, you must
either set the
ibm_db2.instance_name configuration
option in
php.ini, or source the DB2 instance environment in your Web
server start script (typically
/etc/init.d/httpd or
/etc/init.d/apache).
