WSO2 - MSSQL causes error for commits - api

Question

When configuring WSO2 API Manager version 1.5.0 to use SQL Server as my database the instructions at:
http://docs.wso2.org/display/AM150/Setting+up+with+MS+SQL
For step 1 for Setup Configuration File, they tell you to update the master-datasources.xml file to match their example.
After updating and starting the API Manager, I got the following error in the logs:
ERROR {org.wso2.carbon.apimgt.impl.dao.ApiMgtDAO} - Failed to rollback getting user ratings {org.wso2.carbon.apimgt.impl.dao.ApiMgtDAO}
java.sql.SQLException: commit() should not be called while in auto-commit mode.

Answer 1

We tried a couple of things. First we disabled auto-commit on our SQL Server (2008r2).
That did not help and the error continued. After researching jdbc connections at: http://people.apache.org/~fhanik/jdbc-pool/jdbc-pool.html
I discovered that a setting for:
<defaultAutoCommit>false</defaultAutoCommit>
was needed for each database definition in master-datasources.xml
For example:
<datasource>
<name>WSO2_CARBON_DB</name>
<description>The datasource used for registry and user manager</description>
<jndiConfig>
<name>jdbc/WSO2CarbonDB</name>
</jndiConfig>
<definition type="RDBMS">
<configuration>
<defaultAutoCommit>false</defaultAutoCommit>
<url>jdbc:jtds:sqlserver://server:port/db_name</url>
<username>user</username>
<password>pwd</password>
<driverClassName>net.sourceforge.jtds.jdbc.Driver</driverClassName>
<maxActive>50</maxActive>
<maxWait>60000</maxWait>
<testOnBorrow>true</testOnBorrow>
<validationQuery>SELECT 1</validationQuery>
<validationInterval>30000</validationInterval>
</configuration>
</definition>
</datasource>
The documentation from WSO2 does not reference this setting that I have found. It 'might' set it correctly when using the ../carbon admin site for your product.
