I am trying to find the TLS version supported by different Oracle DB, but not getting consolidated information. Below is the chart of my findings:
Any idea, where I will get this info?

I'm using OBIEE 12.2.1.2.0 and I want to create a connection to Postgresql there's no database type for Postgresql in 'Add a New Connection' form.
I would appreciate if any body help me to know whether VA supports Postgresql connections.
Since it's 12.2.1.2 all there's to be said is: The version doesn't have it yet. DV has it already though so the upcoming 12.2.1.4 on-premises should be up-to-date again as well.
We have an external server service running Oracle and we can not access his configuration. We have the code for the application and we are interested in the current implementation of connection.close().
So the question is, running a Oracle 12c database, is it possible to connect to the database using older database driver version such as Oracle 11g? We want to exclude a simple configuration problem by drivers not matching the database product version.
Is there any document (other than JavaDoc) that specificates the implementation behaviour of Connection.close() since the Java spec says its implementation depending and there is no general rule.
If you have Metalink access, you can check MOS note 207303.1 on Client-server interoperability.
In summary, Clients 11.2.0 and above are fully supported; 11.1.0 is supported, but bugfixes are possible only for customers with Extended support.
I have a requirement to connect to oracle database for this I am using OCCI as programming language. I would like is there any restriction on which client version can be used for a corresponding database i.e. Database to which I am connecting is at version 10.1.0.4. Now can I used 11 Client?
Oracle client versions are generally backward compatible. Unless the server is too old. As long as it is a version greater then 10 it should be fine.
Have a look at the link below. There is a matrix showing interoperability details between client and server versions.

We will upgrade out IBM DB2 9.7 LUW to 10.5 LUW. Do we have to upgrade our JDBC driver too, or can we use existing one from 9.7?
Normally you should, in order to have everything at the same level. Each release has an upgrade in the JDBC drivers. You can check this page to see the different JDBC versions: http://www-01.ibm.com/support/docview.wss?uid=swg21363866
In addition, you can check the list of APARs to check if you must change it because of an error. To see the list of enhancements in each version please visit the following link and look for the JDBC section of each fixpack: http://www-01.ibm.com/support/docview.wss?uid=swg21633303
IMO, it depends. I'd check to see if the newer driver includes support for additional features that I want to make available to my application. If you don't need any of the new functionality the motivation to change the driver is reduced. If you have already been using the older driver with your app with no issues then you probably are not affected by any defects that are fixed in the newer driver. Keeping the same driver in place might reduce the QA you have to do as a result of upgrading the database. It would also mean you would not have to push a new driver out to all of your clients. You already know the driver you are currently using plays nicely with your app so by keeping it you can minimize the variables in the upgrade.
The protocols between the two databases are the same with the exception of new functionality added to 10.5. I can't really speak for what IBM supports in this regard but we (DataDirect) support multiple version of the database from one version of the driver. I suspect the same is true with the IBM driver. If you are curious to see how we handle it, we have a support matrix, that shows what versions of the database our current JDBC driver supports.
I maintain a set of applications that use Pro*C to connect to Oracle 10g databases. These applications are generally involved with moving data from one database to another. In each case a connection is made to the source database and a separate connection is made to the target database. For reasons that are out of my control the target databases are to be upgraded to 11g whilst the source databases are not. I have searched the internet unsuccessfully, well I have posed the problem as many different ways as I can think of in google, in order to determine whether connecting to different versions of the database is acceptable .The only, almost relevant, documentation I can find is this Can anyone point me to any other documentation that would allay my clients fears?
The official client/ server compatibility matrix for Oracle is My Oracle Support 207303.1 "Client/ Server/ Interoperability Support Between Different Oracle Versions". That is probably the documentation that your clients would want to see.
The quick version is that if your application were to use, say, the 10.2 Oracle client, you would be able to connect to databases from 9.2.0.4 to 11.2.0.x. If your application were to use the 9.2 Oracle client, you'd be able to connect to databases from 8.1.7.x to 11.2.0.x. If you used an earlier version of the Oracle client, you would not be able to connect to an 11.1 or an 11.2 database.
