Why Do I Fail to Execute Some Redis Commands?

Possible causes include the following:

• The command is incorrect.
• 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 the administrator 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 the administrator for the instance to be upgraded.
