The issue can be resolved in the following ways:
(1) If this is a major version upgrade with hotfix, then uninstall the hotfix, apply GA (i.e., the base version) and then re-apply the hotfix
E.g., Uninstallation steps for 8.4 HF2 but helpful in terms of the context of the procedure.
1. Shut down your running TIBCO Data Virtualization Services that have this hotfix.
2. Run the rollback scripts (i.e. install/rollback_TDV_<component>_080400_HF-002_all.bat/sh) located in your TIBCO Data Virtualization installation directory.
3. For the version you are going back to, reapply the corresponding patch or hotfix again. In other words, unzip the patch/hotfix file under your TIBCO Data Virtualization installation directory.
Example: Rollback to 8.4.0.GA from 8.4.0 HF-002
a) stop all TIBCO Data Virtualization Services with 8.4.0 HF-002
b) run "install/rollback_TDV_<component>_080400_HF-002_all.bat/sh"
c) reapply 8.4.0 GA patch to your TIBCO Data Virtualization installation directory.
If you don't have the 8.4.0 GA patch (i.e., TIB_tdv_server_8.4.0_all.zip), then you can get it
from https://edelivery.tibco.com/storefront/tibco-data-virtualization/prod11801.html.
This gets you to 8.4 GA. So you would still have to patch 8.4 HF2.
(2) If this is a major version upgrade with no hotfix, then reapply the GA.
Restart the TDV Server.
