java.sql.SQLException: ORA-14911: XA transactions are not supported by Transaction Guard

Oracle SOA 12.2.x over Oracle database 12.1 in standby DataGuard with Transaction Guard enabled.

It seems SOA Suite does not support transaction guard, hence you must ask your DBA to configure the service with this setting: COMMIT OUTCOME = FALSE

Enjoy 😉

Developing Rich User Experience Desktop/Mobile Solutions with Oracle JET

JET is the client-side JavaScript framework offered by Oracle. JET utilises de-facto standard technologies such as jQuery, jQueryUI, Knockout, Cordova and so on and allows creating rich and responsive HTML5 user interfaces with equal or less development effort than other frameworks.

JET coexists and integrate very well with the Oracle MW stack, Java, REST and related approaches such micro-services, soa, …, allowing to deploy in WebLogic and integrate with other Oracle products not only on-premises versions (OAM, OBIEE, ORDS/APEX, BPM, SOA, CONTENT) but also with cloud PaaS offering such as Process Cloud Service, Integration Cloud Service, Mobile Cloud Service, Documents Cloud, Identity Cloud Service, Internet of Things Cloud Service, … and is a perfect framework for customising Oracle SaaS offering for adapting Solutions to Customer needs.

And last but not least, JET projects fit perfectly in Oracle Developer Cloud Service for Continuous Integration and Delivery (CI & CD) and Agile PM.

Clone your environment and choose the deploy/run region y in 35 minutes with Ravello

See how easy is to create a perfect clone of your environment and have it running in another location in just a few clicks:

  • If your VM’s are DHCP-enabled set the RESERVE IP for each one to its current IP so that they have the same IP in the destinationclone0
  • Save the application as blueprint and wait a while


  • Create a new application from the blueprint
  • Publish the new application selecting the geographical zone from the list of available datacenters worldwide

That’s all!
