Well, Oracle hardly fixes many errors for Windows OS. They “successfully” inherit bugs in latest versions, mostly because not many businesses are hosting Oracle products on Windows? A poll conducted by https://oracle-base.com reveals just 8% Windows OS share for hosting Oracle products! Interested? read details here

We recently migrated to 19c (19.14) & one of our 3rd party solutions needed to create a Linked Server connection to this instance from MS SQL database. Although 11g client could successfully connect to 19c, I decided to go with the 19c client, that looked less challenging to configure. Installed the client, and tried to install Oracle Services for Microsoft Transaction Server component as additional feature and nightmare started. Software was getting installed, however failing when configuring it.

As the GUI didn’t produce much details about what went wrong, I decided to try configuring it from command line after referring Oracle Services for Microsoft Transaction Server installation documents on Oracle site.

I found a solution immediately there after on stackoverflow. This answer discusses about the registry values that could cause the installation issues for Oracle client version 12.x & quickly I tried the same, and the configuration completed successfully.

So here is how to address the problem. Please make sure that you will take a backup of Windows Registry prior attempting to manually modify the values. A corrupt registry might force you to re-install Windows.

As we could see here, ORACLE_HOME_TYPE after a default install doesn’t have a value, failing MTS in my case. As I was trying to configure the Oracle client, expected value was “2” and for the Database, the value should be “1”

Modify key & exit registry editor.

Try to configure MTS once again from the command prompt. This time configurations must complete successfully!
