We recently attended the two-day Oracle OpenWorld Europe conference and exhibition at the ExCeL Centre in London. The event was packed with IT industry personnel from across Europe and offered both technical sessions and an exhibitor exchange floor all under the same roof, which made this conference very accessible.
Oracle made a number of major announcements. I have listed them below so that you and your organization can take them into account as you plan for the months ahead.
- Customers are encouraged to skip 20c if they are considering an upgrade to their production servers. Version 19c is Oracle’s official Long-Term Support Release following the soon to expire 11g.
- The next Long-Term Support Release will be 22c, scheduled for Q1/2022.
- Good-old senior-citizen release 11g will enter its end-of-life (EOL) period at the end of this year.
- Starting with release 20c, non-container database architecture (CDB) is de-supported.
To help with the transition, starting with 19c, Oracle offers three user-created pluggable databases of any type—without the extra cost typically associated with the multi-tenancy feature.
- 19c (188.8.131.52) new features:
- High-speed data ingestion
- Active Data Guard DML redirect – An interesting feature, yet very latency sensitive, for customers wishing to write to both primary and standby databases. In actuality, each write towards the standby is redirected and committed at the primary.
- Automatic indexing
- Hybrid partition tables
- JSON improvements – As part of the roadmap to become the converged database, Oracle has added native and improved support for non-relational data types such as JSON, mainly resulting in apparent 10x execution time improvements.
- Oracle REST Data Services (ORDS) – An apparent close to full coverage of Oracle database functionality via RESTful APIs, including infrastructure functions such as the Data Guard broker, general data dictionary, monitoring, performance, and PDB lifecycle management.
- Oracle database has been rebranded as the converged database, meaning Oracle is attempting to bring an all-in-one enterprise database solution to relational, NoSQL, graph and other types of databases; up until recently it had called for a dedicated database to handle each kind of data structure.
- 20c (20.1.0) new features:
- AutoML in OML4Py – Introducing native Python and machine learning support at the database
- Native blockchain tables – Continued effort to rebrand the databases as a single converged solution for all kinds of data. Insert only; Update and Delete are not supported by design.
- In-memory vector joins
- JSON speed and flexibility
- Persistent Memory (PMEM) Store – Making the use of Intel Optane technology accessible for applications wishing to harness the power of PMEM in terms of performance, following the recent launch of Exadata X8M, which uses the same technology to accelerate redo writes today.
