Developing Higher Education product using Fusion Middleware and Oracle ADF. The responsibilities are as follows • Go through the FSA, TDD, FDD, TSA documentation. • Generate the DB Schema based on the same • Generate the corresponding JPRs in the JWS and categorize them into Model and View controller projects • Generate a Test project which tests all the ADF BC code written • Generate SOAP/REST services as per specifications. • Fixing UI/Model bugs and then following standard dev processes to review, approve and merge the code into source control • Update the DTCs, FDDs for future maintenance • Generate local build and full build to test end to end integration for the UI • Running automations to capture UI antipatterns and JUnits to get the code clean • Attending regular scrums to decide on the days work and also update daywise progress in the tracker to facilitate taking development efficiency statistics. Oracle ICS or Integration Cloud Services were used to integrate cloud based event propagation between products. This was done as a part of the requirement for certain business scenarios in which two products need to talk to each other but does not necessarily call each others web services. Underlying Oracle SOA was used with a custom middleware API for propagation of custom events which facilitated cross-product interaction on cloud which was faster and much more fault resilient and easy to debug by the business user incase something goes wrong. FusionApps uses SOAP based web services across products to perform various tasks from uploading/downloading files to scheduling jobs. Java based proxies were created using Jdeveloper and the code was customized based on web security policies to mimic the service operations and find out various performance metrics on the fly about the service execution using heap snapshots from server. We implemented a content search cache for Oracle Fusion applications where we are checking in a global search whether the previous search data for the specific search term exists in the ElasticSearch clustered shards or not. If not then DB is queried to fetch it or else we get the metadata of the last search performed from ElasticSearch and invoke the taskflow to get the previous search result in effect mimicking a normal DB based search but much quicker.
