PDO_IBM DSN - Connecting to IBM databases

	The PDO_IBM Data Source Name (DSN) is based on the IBM CLI DSN. The major components of the PDO_IBM DSN are:

	      o DSN prefix
		- The DSN prefix is ibm:.

	      o DSN
		- The DSN can be any of the following:

		     o a) Data source setup using
		       db2cli.ini or odbc.ini

		     o b) Catalogued database name i.e. database alias in the DB2 client catalog

		     o c) Complete connection string in the following format: DRIVER={IBM DB2 ODBC DRIVER};DATABASE=
		       database;HOSTNAME=  hostname;PORT= port;PROTOCOL=TCPIP;UID= username;PWD= password; where the parameters represent the fol-
		       lowing values:

			    o $database
			      - The name of the database.

       Example #1

	      PDO_IBM DSN example using db2cli.ini

	       The following example shows a PDO_IBM DSN for connecting to an DB2 database cataloged as DB2_9 in db2cli.ini:

	      $db = new PDO("ibm:DSN=DB2_9", "", "");

	      [DB2_9]
	      Database=testdb
	      Protocol=tcpip
	      Hostname=11.22.33.444
	      Servicename=56789

       Example #2

	      PDO_IBM DSN example using a connection string

	       The following example shows a PDO_IBM DSN for connecting to an DB2 database named testdb using the DB2 CLI connection  string  syn-
	      tax.

	      $db = new PDO("ibm:DRIVER={IBM DB2 ODBC DRIVER};DATABASE=testdb;" .
		"HOSTNAME=11.22.33.444;PORT=56789;PROTOCOL=TCPIP;", "testuser", "tespass");
