Oracle client support for VAX OpenVMS 7.3 - oracle

Does Oracle support any kind of client and C/C++ pre compiler for VAX OpenVMS 7.3 to connect to a Oracle server? On oracle.com they only have clients for Alpha and Itanium. I am using a simh VAX. And I have a Oracle 11g express database.

You would need to locate some seriously old Oracle distribution.
Oracle release 7.3.4 is the highest Oracle release supported on VAX;
Oracle releases 9.2 and later do not support connecting with Oracle7.
Oracle 7.3.4 may or might not connect to 11G express. I doubt it.
For sure anything above 9i was never supported. See Metalink ( 207303.1 ?)
Here is a public place which has a snapshot of the support matrix: http://oracleappstechnology.blogspot.com/2008/09/placeholder_08.html
You can only stretch that vax so far...
Cheers,

Oracle upgrade from 12c to 19c - older application no longer works

Using an older SQL reporting tool that used oci.dll to interact with Oracle 12c. Upgrade to Oracle 19c and the tool no longer works. Is the instant client for 19c the solution or must we revert to ODBC for access?
Thanks for any insights...

Which Oracle 11g has DBCA?

I am having an issue with Oracle 11g. I need to download an Oracle 11g database that has the Database Configuration Assistant. I had already downloaded Oracle 11g Express Edition not realizing it apparently doesn't have DBCA.
So which Oracle 11g do I need to download so I can use DBCA?
I am on the Oracle website and see Oracle 11g Release 2. I have a Windows laptop with Windows 10.
That would be any other version (Standard or Enterprise).
11gXE has its limitations and creates a sample database during the installation process. As it allows only one instance, DBCA is useless in that version and is, therefore, not shipped with it.
Standard or Enterprise edition of Oracle 11g would do.
I have downloaded the version from Oracle and DBCA worked for me.

Can Oracle Enterprise Manager Grid Control 11g can manage databases that support oracle 10g?

The reason is that I have Oracle Database 10g installed and I am unable to download patches of Oracle Enterprise Manager Grid control 10g from oracle.com. However they are recommending a higher version of 11g . Please Help.
Yes, with 11g grid control you can manage 10gR2 databases, and vice-versa as far as I recall.
As to the particular versions, there is a compatibility matrix in Oracle Support, I don't believe it is public document, however.

Migrate Oracle DB

I had to connect my Oracle 10g XE (10.2.0.1) with Visual Studio 2012.
Since I found that 10g is not compatible now, so I want to migrate it to higher version - 12c.
I have successfully installed Oracle 12c Enterprise Edition, but it's upgrade assistant says that you have to upgrade your 10g (10.2.0.1) to the version 10.2.0.5, then DB can be migrated to 12c.
Question: How to upgrade Oracle 10.2.0.1 to 10.2.0.5 ?
I couldn't find the patch links from internet, I have searched a lot on the internet but didn't not get an amazing solution that resolves my problem in one shot.
This message is an error in the installer. It is applicable to other editions of Oracle (for example to a Standard Edition) but XE does not have such version as 10.2.0.5. Even with an Oracle support contract paid, there is simply no such version on metalink. You need to export-import like described in this question.
You need a metalink account to download this patch (legally); it's probably easier to export the database and import it into a fresh 12c instance.

Oracle 10g xe 64bit version for CentOS 6.2

Are there any places where I could download Oracle 10g Express Edition for CentOS 6.2 64bit environment? I have searched in Oracle official website but I couldn't find a distro. Also I have googled for answers but couldn't find an appropriate one. So, it is much appreciated if anyone could assist me on this please.
According to the Oracle download website, 10g is no longer available, but you can request it using My Oracle Support if you own a valid database license. Unless you explicitly need 10g (e.g. to setup a test environment for supporting a legacy installation), I'd go for 12c instead.
In summary, you have two options:
use 12c Express Edition / 11g Express Edition instead
contact Oracle support to get 10g Express Edition
