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:
- DSN prefix
The DSN prefix is
ibm:.DSNThe DSN can be any of the following:
a) Data source setup using
db2cli.iniorodbc.inib) 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 909. 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 910. 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");
