Test locally first, then deploy to the cloud.
As recommended by Cheuk Chau on Medium, I read ' How to Develop a Daily Writing Habit ’ - I’ll try to put it in practice here with my second advise - should have been my #1 advise: Run a local copy of your application first, before to test it on your cloud instance. While it’s simple to run directly on the Cloud, and we have a lot of samples available to get started, working local first is the best way to get ready when trouble come your way. Samples are available from: Your own Cloud instance SDK : https://javatrialxxxx-usoracletrialxxxx.java.us2.oraclecloudapps.com/doc/index.html another instance of the SDK documentation, hosted for you : https://javas2-jcscdc.java.us2.oraclecloudapps.com/doc/index.html The Cloud documentation books : https://docs.oracle.com/cloud/latest/javacs_gs/index.html OTN samples : http://www.oracle.com/technetwork/indexes/samplecode/cloud-samples-2203466.html Same samples, hosted on github : https://github.com/oracle/Oracle-Cloud
