Of Motorcycles, Databases and the Cloud



What has Oracle to do with motorcycles? At first sight: nothing at all! Except I’m a motor rider myself and I’m doing something with databases. But, inspired by a motorcycle-vlogger I made a mental connection between those area’s, where motorcycles can be replaced by cars or any other luxury goods we are using. Just a small reflection about overlooking the hidden costs or savings.

Motorcycles

To explain the relation, and relevant for this short blogpost, I first need to tell you what bike I own at the moment.

My motorcycle is a Yamaha XT1200Z Super Tenere Worldcrosser with 112 BHP, 1200cc, an impressive machine with massive power, especially designed for people like me, a wannabee world-traveller with little or no experience in off-road riding. The motor has been equipped with all kind of fancy electronics avoiding me falling off, be involved in an accident or get lost. But… you don’t see a lot of dirt-road travellers choose this bike for their adventures. (more…)

Multitenancy: is a Proxy PDB part of the 3 free PDBs at 19c

Multitenancy: is a Proxy PDB part of the 3 free PDBs at 19c

As most of us know, Oracle Database 19c now supports up to 3 pluggable databases (PDBs) per container database (CDB) without requiring additional multitenant license—applicable for both Standard Edition (SE2) and Enterprise Edition (EE). This documentation clearly states: “For all offerings, if you are not licensed for Oracle Multitenant, then you may have up to 3 user-created PDBs in a given container database at any time.” Meaning it’s about user-created PDBS.

But is a Proxy PDB (in fact a kind of symbolic link in Linux terms) considered user-created, or are you allowed to have 4 PDBs in theory? Once, I attended a presentation of Carajandb (Johannes Ahrends) in Germany, who stated that a Proxy PDB is free to use, based on the 18c documentation.
