Freelance Project to adjust Oracle 12c databases for a .NET WCF Application


We are a company that provides a .NET WCF based application. Our product supports either Oracle or SQL Server databases. One of our customers uses Oracle 12c for this application and we have been facing some issues with the availability of their database.


We will consider this project finished when:

- The database services are stable;

- You provide a didactical documentation of all the adjustments you had to make to the database.


The goal of this project is to generate a document artifact with all the adjustments we need to do on the database so that we can retain this knowledge for further reference.


We expect you to start working as soon as we provide the remote access.

We also expect that this project will take up to 15 days (mainly for validation).


After a short period (generally a week) of normal database usage, we are not able to connect to the databases until we restart the Oracle Listener Service. Even if we are using SQL Plus. There is only one instance of Oracle installed, but there are two PDB (Pluggable Databases) for different purposes: one is for production use and the other is for quality assurance (version validation). Still, both of them use the same listener and both start failing.

Since the data is confidential and sensitive, all tasks must be done via remote assisted operation with one of our developers.

If you need further information, please ask.
