Oracle database 18c xe.
After installing db 18c xe, I found that there is a pluggable database named XEPDB1. But the documentation states that,
Zero or more user-created PDBs
A PDB contains the data and code required for a specific set of features (see "PDBs"). For example, a PDB can support a specific application, such as a human resources or sales application. No PDBs exist at creation of the CDB. You add PDBs based on your business requirements.
Notice the red line above. Is it contrary? Is it created by default for a specific purpose?
Can I use that PDB as any self created PDB or should I create a new one?
