java.sql.SQLException: Could not commit with auto-commit set on

I saw this earlier: -

[14/07/17 20:00:02:593 BST]     FFDC Exception:java.sql.SQLException SourceId:com.ibm.ws.rsadapter.jdbc.WSJdbcConnection.commit ProbeId:587 Reporter:com.ibm.ws.rsadapter.jdbc.WSJdbcConnection@964a1c09
java.sql.SQLException: Could not commit with auto-commit set on

in the FFDC logs for an IBM BPM 8.57 JVM: -

I am using Oracle 12c ( specifically 12.2.0.1.0  )

and am using the version of the Oracle JDBC drivers that ship with WAS 8.5.5.11: -

ls -altrc /opt/ibm/WebSphere/AppServer/jdbcdrivers/Oracle/

Source: Checking the Oracle JDBC Driver Version on a Weblogic Server

Thankfully, this IBM developerWorks Answers ( dwAnswers ) page: -


provides an answer: -

This kind of exceptions occur when the Oracle JDBC Driver (ojdbc6.jar) version 12 or above will be used. Version 12 and above of the driver is more strictly than earlier driver versions. You can solve the problem, by setting the jvm-argument:

•  -Doracle.jdbc.autoCommitSpecCompliant=false
on all affected servers.

as does this IBM Technote: -


Once I added the JVM property, and restarted the AppCluster, all was well.

For the record, this is what I now have in server.xml in the context of JVM arguments: -

    <jvmEntries xmi:id="JavaVirtualMachine_1499716654178" verboseModeClass="false" verboseModeGarbageCollection="true" verboseModeJNI="false" initialHeapSize="1536" maximumHeapSize="2560" runHProf="false" hprofArguments="" debugMode="false" debugArgs="-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=7777" genericJvmArguments="${IBMSCMX} ${IBMGCPOLICY_GENCON} ${IBMJITPMC} -Xmns256m -Xmnx768m -Xgc:preferredHeapBase=0x100000000 -Xdisableexplicitgc -Xss2048k -Dsun.net.http.allowRestrictedHeaders=true -Declipse.bundle.setTCCL=false  -Doracle.jdbc.autoCommitSpecCompliant=false" executableJarFileName="" disableJIT="false">

and, via the GUI: -
