    PDO_IBM DSN — Connecting to IBM databases

    Description

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

    DSN prefix

    The DSN prefix is ibm:.

    DSN

    The DSN can be any of the following:

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

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

    • 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 following values:

      database

      The name of the database.

      hostname

      The hostname or IP address of the database server.

      port

      The TCP/IP port on which the database is listening for requests.

      username

      The username with which you are connecting to the database.

      password

      The password with which you are connecting to the database.

    Examples

    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 syntax. 

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

    To correctly display and otherwise handle strings from Db2 in php you should set an environmental variable DB2CODEPAGE. For UTF-8 database it is usually 1208.

    For example, put
    env[DB2CODEPAGE] = 1208
    in your /etc/php-fpm.d/www.conf file.

    The connection string is wrong for the example :
    $db = new PDO("ibm:DRIVER={IBM DB2 ODBC DRIVER};DATABASE=testdb;" .
    "HOSTNAME=11.22.33.444;PORT=56789;PROTOCOL=TCPIP;", "testuser", "tespass");

    You get the PDO Exception with the error code -1329.

    You have to write :
    $db = new PDO(
    "ibm:DRIVER={IBM DB2 ODBC DRIVER};DATABASE=testdb;" .
    "HOSTNAME=11.22.33.444;PORT=56789;PROTOCOL=TCPIP;UID=testuser;PWD=testpass",
    "",
    "");
