MySQL Cluster Manager (MCM) Not Able To SET/RESET Configuration Parameter : ERROR 6019 (Doc ID 2064787.1)

Last updated on NOVEMBER 23, 2015

Applies to:

MySQL Cluster - Version 7.0 and later
Information in this document applies to any platform.


The issue can be reproduced at will with the following steps:

  1. By mistake, set (change) incorrect values for the config parameters, for a full functional Cluster.
  2. The set command requires the data node to be restarted with the new config value. 
  3. Some of these changes can prevent the data nodes from starting up. These changes typically requires memory or storage at OS level.
  4. Now trying to undo (via set or reset) the change done , so that the data node could start, will fail since it requires the data node process to be started. 


 Set a configuration parameter to an value that makes the Cluster Data node (ndbd/ndbmtd) to fail the restart.
