Major benefits with JAVA 7 and WLS 12c as it addresses many bugs for huge file size handling 6) Any changes in EM level monitoring? No major change in EM monitoring except that FMW control is difficult to include because of the need to have DB schema. 7) Anything addition done to accommodate in Weblogic 12c- Nothing much additional except java7 usage.

- Active GridLink for RAC, as the name suggests is a new feature area for hooking WebLogic Server up to Oracle Database RAC. This feature dramatically changes the equation around working with RAC if you are an application server user. Before this feature, WebLogic already was the only Java EE 5 application server on the market with declarative integration with RAC using a feature called Multi Data Sources and these continue to be supported. However, Active GridLink for RAC takes this integration to a new level. There are 5 key features of GridLink : Single data source for an entire RAC cluster - if your RAC clusters are large and you have many different WebLogic domains, GridLink data sources can dramatically reduce configuration. RAC workload awareness - runtime connection load balancing. GridLink data sources are notified proactively of the workload on RAC nodes and can balance connections to least loaded nodes resulting in much more even utilization in your RAC environment from your middle tierTransaction affinity where global transactions have an affinity context assigned to a specific RAC instance enabling significantly better performance Fast Connection Failover - event based notification of the WebLogic connection pool of changes in the RAC cluster and graceful recovery in these events - e.g. RAC nodes being added for capacity or nodes being removed for maintenance.
