Hi all the direct2020 cartridge is not compatible with Oracle 19c as it appears due to a bug mentioned in the system requirements:
"IMPORTANT! BIOVIA Direct 2020 does not support Oracle 18c and 19c at this time due to Oracle bug 30328168. Refer to the Dassault Systèmes Knowledge Base (https://www.3ds.com/support/) to view the latest information on Oracle 18c/ 19c support for this release."

I just checked the latest oracle releases and it appears this bug has been fixed. Is there a hotfix we can apply to enable installations 19c now?
