Oracle 12c, released in 2014, brought numerous new features to the database. Here are some of the key new features along with their challenges for users and DBAs:

1. In-Memory Computing (IMC): Oracle introduced IMC to enhance performance by storing data in memory. Challenges include managing large amounts of in-memory data, ensuring consistent data across multiple instances, and maintaining compatibility with existing SQL queries.

2. Complex Event Processing (CEP): CEP allows the processing of complex patterns in real-time data streams. Challenging aspects include developing and maintaining event correlation rules, scalability to handle high volumes of events, and timely alert generation for critical events.

3. Columnstore Indexes: Oracle introduced columnstore indexes to improve query performance by storing data in a column-oriented format. Challenges include learning how to use the new index type effectively, optimizing queries that work with columnstore indexes, and managing storage requirements as the data grows.

In conclusion, while Oracle 12c brings significant new features, it also presents challenges for users and DBAs in terms of adapting to new technologies, optimizing queries, and managing storage.
