About oracle database and instance, can I create database in XE edition? -


i think, oracle instance serial of os process, , oracle database set of database files.

and oracle instance can mount database linux can mount disks.

so, in xe cannot run 2 instances, can create multiple databases , use instance mount , unmount.

but after reading this thread, i'm confused.

you can have 1 xe 'database' or 'sid', can have multiple schemas.

no. can have 1 xe database per server. can have many schemas in database you'd like. if coming background in other databases, databases refer database equivalent oracle refers schema.

see similar stack overflow question:

can have multiple databases on oracle express edition

oracle xe has following hardware limitations:

  • only use 1 cpu on system
  • use 1gb of ram
  • store 4gb of data, 11gb of data on 11.2
