I'm trying to connect to a client's IBM AS/400 DB2 Database from an Ubuntu Server using PHP's ODBC Driver. I have the unixODBC installed as well. My odbcinst.ini looks like this:
[IBM DB2 ODBC DRIVER]
Description = ODBC 5.1 Driver for Database
Driver = /usr/lib/x86_64-linux-gnu/odbc/libmyodbc.so
FileUsage = 1
And my odbc.ini looks like this:
[IBM DB2 ODBC DRIVER]
Driver = IBM DB2 ODBC DRIVER
Description = ODBC 5.1 Driver DSN
Now, my code to connect is:
$server = '12.345.678.90' //IP
$port = '446' //PORT
$username = 'my_username';
$password = 'my_password';
$connect = odbc_connect("DRIVER = {IBM DB2 ODBC DRIVER};System=$server:$port;Uid=$username;Pwd=$password;", $username, $password);
if(!$connect)
echo 'Cannot Connect!';
else
echo 'Connected!';
The error I get is this:
Warning: odbc_connect(): SQL Error: [unixODBC][MySQL][ODBC 5.1 Driver]Access denied for user 'my_username'@'localhost' (using password: YES), SQL state S1000 in SQLConnect
I tried using the PDO ODBC Driver also. This is the error I get:
$connect = new PDO("odbc:DRIVER={IBM DB2 ODBC DRIVER};HOSTNAME=$server;PORT=$port;Uid=$username;Pwd=$password");
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] SQLDriverConnect: 1045 [unixODBC][MySQL][ODBC 5.1 Driver]Access denied for user 'my_username'@'localhost' (using password: YES)' in /var/www/test_file.php Stack trace: #0 /var/www/test_file.php: PDO->__construct('odbc:DRIVER={IB...') #1 {main} thrown in /var/www/test_file.php
Am I doing something wrong here? Do I need to use some other driver, because the username and password are correct, I saw the client log in to the database using the username and password I have. I thought the username and password were wrong because it says Access Denied for user. It doesn't seem to be the case. There might be something else that's wrong.
Thank you for your help. I hope I made the problem very clear. Thanks!
Your odbcinst.ini file is saying to use the MySQL ODBC driver:
Driver = /usr/lib/x86_64-linux-gnu/odbc/libmyodbc.so
but you need to use the iSeries Access ODBC driver. The reason you're getting an Access Denied for User
message is because you're trying to connect to your MySQL database with credentials for the IBM i.
Here are step by step instructions for how to connect to DB2 for i (on the IBM i) on Ubuntu:
Download the free iSeriesAccess-6.1.0-1.2.i386.rpm
file from IBM (you'll have to create a free account to get it - and I'm sure there is a more recent version than 6.1.0-1.2)
Convert the RPM file to something Ubuntu understands: sudo alien iSeriesAccess-6.1.0-1.2.i386.rpm
Install the resulting .deb: sudo dpkg -i iseriesaccess_6.1.0-2.2_i386.deb
Copy the installed iSeries libraries to where Ubuntu expects them: sudo cp /opt/ibm/iSeriesAccess/lib/* /usr/lib
Edit the /etc/odbc.ini file to contain:
[primary]
Description = primary
Driver = iSeries Access ODBC Driver
System = IP_ADDRESS
UserID = USERNAME
Password = PASSWORD
Naming = 1
DefaultLibraries = QGPL
Database = XXXXXXXXXX
ConnectionType = 0
CommitMode = 2
ExtendedDynamic = 0
DefaultPkgLibrary = QGPL
DefaultPackage = A/DEFAULT(IBM),2,0,1,0,512
AllowDataCompression = 1
LibraryView = 0
AllowUnsupportedChar = 0
ForceTranslation = 0
Trace = 0
Edit the /etc/odbcinst.ini file to contain:
[iSeries Access ODBC Driver]
Description = iSeries Access for Linux ODBC Driver
Driver = /usr/lib/libcwbodbc.so
Setup = /usr/lib/libcwbodbcs.so
NOTE1 = If using unixODBC 2.2.11 or later and you want the 32 and 64-bit ODBC drivers to share DSN's,
NOTE2 = the following Driver64/Setup64 keywords will provide that support.
Driver64 = /usr/lib/lib64/libcwbodbc.so
Setup64 = /usr/lib/lib64/libcwbodbcs.so
Threading = 2
DontDLClose = 1
UsageCount = 1
And then to create the connection with PDO:
$pdo = new PDO("odbc:DRIVER={iSeries Access ODBC Driver};SYSTEM=$server;PROTOCOL=TCPIP", $username, $password);
