To create a user and tablespace in Oracle, you can follow these steps:

  1. Login to the Oracle database with sysdba privilege.
  2. To create a new table space, you can use the following command:
  3. Create a tablespace with the name ‘表空间名称’, datafile located at ‘路径/文件名.dbf’, initial size determined by ‘大小’, and autoextend option enabled.
  4. The tablespace name is the name of the tablespace you want to create, the path/file name.dbf is the path and file name of the data file, and the size is the initial size of the tablespace. Setting AUTOEXTEND ON means that the tablespace will automatically extend when it becomes full.
  5. To create a new user, you can use the following command:
  6. Create a user with the username, password, default tablespace, and unlimited quota on the tablespace.
  7. The username is the name of the user you want to create, the password is the user’s password, and the tablespace name is the name of the tablespace you created in step 2. QUOTA UNLIMITED ON tablespace name means that the user has unlimited quota on that tablespace.
  8. Grants users appropriate permissions to use the following commands:
  9. Give permission to the username.
  10. The permissions can include database operations such as SELECT, INSERT, UPDATE, and DELETE.

The above are the basic steps to create users and tablespaces in Oracle, further configurations and adjustments can be made based on actual needs.
