How does the linux Server export data from the oracle database?

Solution to EXP-00056: ORACLE error 12154 encountered:

Some users asked this question: How do I escape the @ symbol in the password during the export operation?

Because the default Oracle will parse the strings after the @ symbol as the service name, it will not work without processing.

Some enterprises Add the @ symbol to their passwords because of security rules.

Assume that the user password is as follows: SQL> alter User eygle identified by "eygle @ com"; user altered. if the default export fails, the following error occurs: [oracle @ jumper oracle] $ exp eygle/eygle @ com file = eygle. dmp tables = test
