So a while back we moved off WebCenter Content and WebCenter Portal because we where not using an features of the product and we had no need to use them. We removed WebCenter Portal that we where using for two Dashboards and our menu. We wrote a custom menu using ADF and the database, this took us about a month of work and testing but has saved us many man months of development time. We also have custom built dashboards in the same vain which was about two month work of effort. We removed WebCenter Content that we where using as a pure data store. We built a microservices based implementation for our document repository and store which is working very well and take little to no maintenance and is very easy to scale. I do believe these are very viable products now that they have sorted the versioning out (we where trapped on 11.1.1.7 for a while because of this) but we where really not using enough of the features to make them viable for us.

The move to Exadata and Cloud at Customer - Database:  Why Exadata:  Performance - Exadata is engineered to run the Oracle database, and we can now eliminate hardware as a cause of performance problems, eliminate storage latency issues. Every feature of the Oracle Database - enough said. Why Cloud at Customer:  Alleviates problems with hardware and avoiding patching and hardware problems seems like a big win to me. Data security: Unfortunately we have some very important information stored in our system and the cloud was not an option Scalability: With PAAS we will be able to meet our horizontal scalability needs. Interesting findings and other notes: 1) Maximum 8 VM's on the Exadata 2) Active / Active and RAC Database conversion: 1) Character Set Conversion:  https://docs.oracle.com/database/121/NLSPG/ch11charsetmig.htm#NLSPG983  there is a document and a utility ( DMU ), color me surprised.

After a two year of blogging break I am back to blogging. What has changed: in a nutshell new stuff and exciting new challenges, Why the break: I really can't say I have done any ground breaking work in the last couple of years and although I was still solving hard problems they seemed like the same pattern repeated. Also I have been quite disillusioned with ADF, Solaris, java and the general direction of the products I was using. What is to come: We will be moving off our current T5-8 Solaris hardware onto Oracle cloud @ Customer. This means a move from SPARC to x86. The initial plan was SPARC to Dell server on-prem. JCS and Exadata for now until we can do a port of our ADF applications onto a more cloud native platform.
