 Description   

The IBM jdbc drivers can be run in Type 2 (native) or Type 4 (pure Java). By
default, Type 2 seems to be used.

Type 2 is much more restrictive, since native libraries are required. Different
libraries are used for each platform, and certain platforms (e.g., MacOS) appear
not to be supported at all.

The IBM drivers are the only ones that are supported in Type 2.

Unless there are additional mitigating factors, the drivers should be used in
Type 4 by default.

The problem with the type 4 driver is that it does not support XA.

However, that being said, the DataSource should be one of the following
(universal driver) and not com.ibm.db2.jdbc.DB2DataSource:

  • com.ibm.db2.jcc.DB2SimpleDataSource
  • com.ibm.db2.jcc.DB2DataSource
  • com.ibm.db2.jcc.DB2ConnectionPoolDataSource
  • com.ibm.db2.jcc.DB2XADataSource

The driverType property should also be specified and either defaulted to 2 or 4

Bulk update to change fix version to "not determined" for all issues still open but with a fix version for a released version.
