I recently caught up with Seiden Group CTO Stephanie Rabbani about the ODBC driver that’s quickly becoming standard for open source and web connections on Db2 for i.
Bill of lading template for mac. Step #1: Downloading Windows ODBC drivers. For IBM i ODBC access from a Windows machine, companies generally use these ODBC drivers: Client Access ODBC Driver (32-bit) iSeries Access ODBC Driver. IBM i Access driver. Some shops also use ODBC drivers from Microsoft and other companies to access IBM i data, but today let’s focus on IBM’s drivers. IBM's technical support resource for all IBM products and services including downloads, fixes, drivers, APARs, product documentation, Redbooks, whitepapers and technotes.
Steph, looks like ODBC is back! Where has it been for the past 20 years?
- Download the IBM DB2 ODBC Driver from the 'IBM Data Server Driver' package within IBM Fix Central, for SPSS Modeler 18.0 FP1 this is 'DSClients-macos-dsdriver-11.1.1.1-FP001' that can be downloaded from.
- Sep 02, 2020 IBM Data Server Driver Package (DS Driver) This package contains drivers and libraries for various programming language environments. It provides support for Java (JDBC and SQLJ), C/C (ODBC and CLI),.NET drivers and database drivers for open source languages like PHP and Ruby.
I guess it was hibernating! My understanding is that with the ODBC standard, IBM Rochester no longer needs to create and maintain unique adapters for all the new languages coming to the platform. Most languages can already use ODBC. What’s more, IBM already maintained ODBC drivers for Windows and Linux, so why not the IBM i itself? And now Apple Mac computers. Plus, ODBC works really well.
How are you using ODBC with PHP these days?
ODBC is our go-to driver for the PHP RPMs. Since Zend Server Basic is being discontinued next year, we’re helping lots of clients migrate to the PHP RPMs! We do maintain a high quality 64-bit build of ibm_db2 for clients who need backward compatibility, but ODBC is the standard going forward.
Which PHP extensions do you use?
PHP provides a choice of two odbc extensions: ‘odbc’ and ‘PDO_ODBC.’ We usually prefer PDO_ODBC. Not only is PDO_ODBC compatible with other PDO database extensions, but it does more than the old ‘odbc’ extension. For example, PDO_ODBC can read output parameters from Db2 for i stored procedures.
Any other languages?
I love Python (let us know if you need Python code developed or need training!) and use pyodbc. Liam has been developing APIs with Node.js and node-odbc. Oh, and let me know if you’d like to see how I produced beautiful graphs based on IBM i data with the R language and RODBC.
What do other developers say about ODBC being available on IBM i?
They love being able to run the same code from their PCs and on IBM i, connecting to Db2 for i from both. They can use their “local” development tools while programming, then deploy to the i.
How do you install the ODBC driver?
It’s free for IBM i customers. Best torrent sites for music production. The package has two parts: the industry-standard unixODBC driver manager and a specific Db2 for i driver. You’ll need your IBM user ID to log in to the Access Client Solutions site and download the package. Gb instruments circuit alert gvd 504a manual. Our friend Mark Irish has provided official installation instructions:

How easy is ODBC to configure? Free urdu inpage 2016.
As a programmer who likes to dive right in, I love simple INI files where I can try all the options. And INI files (odbc.ini and odbcinst.ini, both in /qopensys/etc/) are what unixODBC gives us. There are a ton of options, and best of all, they are well documented.

Some people also like this database-neutral unixODBC documentation: http://www.unixodbc.org/odbcinst.html
What about performance?
My testing with Neoload shows better performance with less CPU than the older proprietary drivers! For best speed, I recommend either connection pooling, or persistent connections if your language supports it.
Thanks, Steph! Any other words of wisdom?

Question
How do you configure Modeler Client on a Mac to access DB2 LUW using the IBM DB2 ODBC driver?
Answer
1. Download the ODBC driver Manager from http://www.odbcmanager.net and install with the default settings.2. Download the IBM DB2 ODBC Driver from the 'IBM Data Server Driver' package within IBM Fix Central, for SPSS Modeler 18.0 FP1 this is 'DSClients-macos-dsdriver-11.1.1.1-FP001' that can be downloaded from:
Ibm Odbc Driver Download
https://www-945.ibm.com/support/fixcentral/swg/selectFixes?parent=ibm~Information%2BManagement&product=ibm/Information+Management/IBM+Data+Server+Client+Packages&release=11.1.*&platform=Mac+OSX&function=fixId&fixids=*macos_dsdriver*FP001*&includeSupersedes=0&source=fc
NOTE: for up-to-date information on supported ODBC drivers refer to the footnotes of the DB2 entry in the IBM SPSS Modeler Related Software Reports on the IBM Software Compatibility Reports for the version of SPSS Modeler that you are using, http://www-969.ibm.com/software/reports/compatibility/clarity/index.jsp
Odbc Driver Manager Download
3. Install the ODBC driver:
a. Create a folder ‘dsdriver’ under /Applications
Ibm Odbc Drivers For Mac Download
b. Double click the downloaded v11.1.1fp1_macos_dsdriver.dmg file and a 'dsdriver' window will open
Download Odbc Drivers Windows 7
c. Double click ‘installDSDriver’
4. Configure the ODBC Driver Manager and ODBC Driver
a. Open ODBC manager, and in Driver tab, add DB2 native driver. Specify ‘DB2 Native Driver’ in the 'Driver Name' slot and ‘/Applications/dsdriver/lib/libdb2.dylib’ in the 'Driver File' slot - no other information is required here.
b. In the 'System DSN' tab of ODBC Manager create a DB2 DSN
i. In the 'Choose a Driver' slot specify the 'DB2 Native Driver' you defined in 4.a. above
ii. Specify a DSN in the 'Data Source Name (DSN) slot, eg. 'DB2v11' and click on 'Add' to create the system DSN.
c. Configure the DB2 Native Driver to connect to your DB2 instance:
Define the DB2 server information in the config file db2dsdriver.cfg under /Applications/dsdriver/cfg. An example of this is (using the example DSN 'DB2v11' as specified in 4.b.ii. above):
<?xml version='1.0' encoding='UTF-8' standalone='no' ?>
<configuration>
<dsncollection>
<dsn alias='DB2v11' host='<IP_or_HOST_NAME>' name='SAMPLE' port='50000'>
</dsn>
</dsncollection>
<databases>
<database host='<IP_or_HOST_NAME>' name='SAMPLE' port='50000'>
<parameter name='CommProtocol' value='TCPIP'/>
<parameter name='UID' value='<YOUR_DB2_USER_ID>'/>
<parameter name='EnableCharToWCharMapping' value='1'/>
<parameter name='XMLDefaultDescribeMapping' value='-98'/>
<parameter name='XMLDefaultCMapping' value='1'/>
<parameter name='LobAsLongDataMode' value='1'/>
</database>
</databases>
</configuration>
NOTE: Ensure the DSN in ODBC manager matches the one specified in the cfg file.
For more details of the configuration file, please refer to https://www.ibm.com/support/knowledgecenter/en/SSEPGG_11.1.0/com.ibm.swg.im.dbclient.config.doc/doc/c0054555.html
Also, if you need to use db2 commands to create or edit db2d2driver.cfg, or validate the contents of it, please add the profile file ‘db2profile’ under /Applications/dsdriver into your profile ($HOME/.profile).
You can validate the datasource you have defined outside of Modeler to ensure it is correctly defined by running the following from a terminal on the Mac, in the event of connections issues from within Modeler ensure this step succeeds and diagnose any issues with reference to the DB2 documentation:
db2cli validate -dsn <DSN> -connect -user <DB2USER> -passwd <DB2PASSWD>
substitute <DSN>, <DB2USER> and <DB2PASSWD> for the DSN you have created in db2dsdriver.cfg, and the DB2 username and password respectively.
