[Oracle] database backup

owner parameter

The owner parameter of the Oracle database can specify a list of user names. When exporting, only objects owned by users in the username list will be exported, as shown in Example 2.

[Example 2] Demonstrate the use of the owner parameter.

exp system/abc123 owner=(test, oracle) file=d:/b.dmp

[Code description] owner=(test, oracle) specifies that the exp command only exports objects owned by two users, test and oracle. If a certain user does not exist, for example, the user oracle does not exist in this example, a corresponding warning will be given, but the export of objects for the user test will not be affected.
