Why Do I Fail to Execute Some Redis Commands?

Possible causes include the following:

  • The command is incorrect.

    As shown in the following figure, the error message is returned because the correct command for deleting a key should be del.

  • A command available in a higher Redis version is run in a lower Redis version.

    As shown in the following figure, the error message is returned because a stream command (available in Redis 5.0) is run in Redis 3.0.

  • The command is disabled in DCS.

    For security purposes, some Redis commands are disabled in DCS. For details about disabled and restricted Redis commands, see Command Compatibility.

  • The LUA script fails to be executed.

    For example, the error message "ERR unknown command 'EVAL'" indicates that your DCS Redis instance is of a lower version that does not support the LUA script. In this case, contact technical support for the instance to be upgraded.

  • The CLIENT SETNAME and CLIENT GETNAME commands fail to be executed.

    This is because the DCS Redis instance is of a lower version that does not support these commands. In this case, contact technical support for the instance to be upgraded.
