Hi @Stanislav
Thanks for your questions, let me answer them one by one.
First - Single Node installation require minimum 12 Cores. Are there any requirements for the separation of processor cores into sockets? How to optimally distribute processor cores on sockets?
No, we don't require anything beyond what's documented. Socket configuration is up to you .. we would like 12 cores. And that's for a Production Installation - one in which many jobs run in parallel.
Second - QDC requires installation custom build of PostgreSQL 11.2. This may raise questions from the client’s information security. In case of requesting certificates and other documents confirming the “cleanliness” of the build, are you ready to provide them?
Yes, I can tell you its a production version of the pg, with one exception. It had to be recompiled to support long object names. That's why they distribute the image. If it would help your cause , a valid question would be if they could supply their own pg, and recompile it themselves for long object names.
Third - «All JDBC drivers needed for database connectivity”. Can you clarify which JDBC drivers should be installed?
Sure, this one is easy : whatever sources you intend to ingest from. QDC can pull data from Oracle, SQL Server, sqoop .. there are many. Point being .. QDC does not supply them - they need to be manually downloaded and placed in the correct QDC directory.
Is QDC functioning correctly without opening ports 80 and 443?
The webserver part of QDC needs to open up a listener .. our default is 8080, but it's configurable. QDC has no interaction with 80, and will only interact with 443 when QDC is secured (another topic entirely).
QDC requires a cloud licensing server to function properly. Is it so? Is it possible to function if the server does not have Internet access?
QDC does not require cloud licensing server (unless a publish involves a cloud server) .. but outside of that: no. No such requirement. That said - QDC does, during install, need to get to the internet. In order to pull binaries and only during install time. Once the install is done : QDC can be unplugged from the internet. If needed I could inquire about a version of QDC that could install entirely without the internet, let me know if that's needed.
Hope this helps, and thanks!
David
