This post details a specific challenge encountered during a non-CDB to PDB migration when the database remained in RESTRICTED mode due to encryption-related errors. The issue arose from a missing TDE key, despite the absence of encrypted tablespaces. The process of locating the required master key is described with merging it into the CDB wallet, and ultimately exporting and importing the key to resolve the violation.

Oracle Forms 6i applications are not compatible with Oracle Database 19c because Forms 6i is obsolete and no longer supported. Today, organizations have three options: move to Oracle Forms 14c, switch to Oracle APEX or completely rewrite the application using current web technologies. In this post, however, I will provide a a short-term workaround that requires minimal effort and almost no changes to the existing application code by using a Forms 10g web server. It works as a bridge solution, but it is not where you want to stay long term.

Oracle Database 26ai was released for on-premises environments on January 27, 2026, bringing a big wave of new capabilities, over 300 features, especially around AI and developer productivity. It’s definitely an exciting step forward, but like with any new major release, early adoption can still carry some risk in terms of bugs and overall stability. That’s why, for most production systems today, Oracle Database 19c is still the safer and more practical choice, thanks to its proven stability in production systems and extended support through 2029.

This blog post describes a complex Oracle database patching issue encountered. Initially, the plan involved applying the 12.1.0.2 database bundle patch – 34057733; however, conflicts arose with existing one-off patches. A rollback was necessary, which unexpectedly caused all database options/features to show as FALSE, impacting database functionality. After extensive troubleshooting , the issue was resolved by applying a different patch that restored the necessary features and some tricks to make DBMS_SQLPATCH valid again.

This post presents an updated Oracle 19.28 Release Update patching guide based on feedback and practical experiences. The objective remains to simplify patching for easier execution. The use of Ansible is emphasized for its consistency and repeatability in patching processes. The post includes detailed instructions for preparation, execution, Datapatch, and cleanup. Users are encouraged to validate operations and maintain backups, highlighting the importance of testing in non-production environments.
