Ignition includes an IBM DB2 driver, however, it will not work for all IBM databases. This article explains how to create a custom driver in order to successfully connect to IBM AS400 iSeries database (QAS).
If you try to connect to an IBM AS400 iSeries database using the IBM DB2 driver included with Ignition, the connection will either report as "Faulted", or be stuck in the "Connecting" status. You may also see error like the following posted in the log:
org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory
([jcc][t4][4.7.85] The version of the IBM Universal JDBC driver in use
is not licensed for connectivity to QAS databases.
To connect to this server, please obtain a licensed copy of the IBM DB2
Universal Driver for JDBC and SQLJ.
An appropriate license file db2jcc_license_*.jar for this target platform
must be installed to the application class path
Connectivity to QAS databases is enabled by any of the following license
files: [ db2jcc_license_cisuz.jar ]. ERRORCODE=-4472, SQLSTATE=42968)
To connect to a database, Ignition uses a JDBC driver. JDBC drivers are specific to the particular database(s), so it is important to use the driver that works with the particular database you are trying to connect to. To connect to a QAS database, Ignition needs the JTOpen driver (jt400.jar). The steps below will walk you through downloading, installing, and configuring this driver to work with Ignition.
Download the driver file
Download the latest driver from the JTIOpen project page.
Extract the zip archive and locate the
jt400.jarfile. You will need the path to this file in the next step.
Create a new driver in Ignition
Follow the steps for adding a JDBC driver outlined in the Ignition user manual. Use the following settings:
Name Use a descriptive name for your new driver, for example AS400 Description This is optional; you can add a description of your choice Class name
Jar File(s) Navigate to the
jt400.jarfile you obtained in step 1.
Driver Type Generic URL Format
URL Instructions This is optional; you can add instructions of your choice Default Connection Properties This is optional, but the following are helpful:
Connection Properties Instructions This is optional; you can add instructions of your choice Default Validation Query
select 1 from sysibm.sysdummy1
Default Translator DB2 URL Instructions This is optional; you can add instructions of your choice
Create a new database connection using your new driver
Follow the steps described in the user manual to create a new database connection. Make sure to select your new driver when prompted.
Your new IBM AS400 database connection is now ready to use.
