We've received questions about Pega's support for the next "Long-Term" release, Oracle Database 19c. Pega Platform 8.4 has been certified with Oracle 19c in the Platform Support Guide.
Older Pega Platform releases have not been certified with 19c, in accordance with our forward-looking platform support policy. However, our testing of 19c (and 18c previously) uncovered zero compatibility issues. We have every reason to believe a system upgraded from 12c to 19c will be successful. Pega will support any system that has upgraded from Oracle 12c to 19c, regardless of the Pega Platform version. Pega strongly recommends backing up the database before performing this upgrade.
IMPORTANT: If clients do use Oracle 19c with older versions of Pega Platform, they must update their Oracle JDBC driver from orajdbc7.jar (Oracle 12c) to the more current orajdbc8.jar (for Oracle 19c). Otherwise, performance is much slower.
Using new features provided by 19c does require Pega Platform 8.4+.
This is not a change in policy and is consistent with the general statements in our Platform Support Guide. But the volume of questions has been high, so I thought it would be worth publishing this extra note.

We are running with PEGA 7.3.1 version along with Oracle 12C(12.2.01). As end of support for Oracle 12C has been officially over by Mar 2022. Hence my client is asking us to upgrade the latest version of Oracle like 19C. will there be any impact if we migrate to database alone from 12C to 19C with same PEGA V7.3.1 or else do we also need to upgrade PEGA version. Please suggest.
