The JAR file for the Oracle driver is ojdbc14.jar.
When using this driver, keep in mind that you cannot insert more than 2000 bytes of data into a column. To circumvent this problem, use the OCI driver (JDBC type 2).
Configure the connection pool using the following settings:
Name: Use this name when you configure the JDBC resource later.
Resource Type: Specify the appropriate value.
Database Vendor: Oracle
DataSource Classname: Specify one of the following:
user – Set as appropriate.
password – Set as appropriate.
URL – Specify the complete database URL using the following syntax:
xa-driver-does-not-support-non-tx-operations - Set to the value true. Optional: only needed if both non-XA and XA connections are retrieved from the same connection pool. Might degrade performance.
As an alternative to setting this property, you can create two connection pools, one for non-XA connections and one for XA connections.
For the Oracle thin driver, the XAResource.recover method repeatedly returns the same set of in-doubt Xids regardless of the input flag. According to the XA specifications, the Transaction Manager initially calls this method with TMSTARTSCAN and then with TMNOFLAGS repeatedly until no Xids are returned. The XAResource.commit method also has some issues.
