This section describes how to change the database password of the eLog analyzer.


  • If the password of the commonuser of the database changes, you must change the password of the database used by the eLog accordingly.
  • The analyzer has been stopped. For details, see Stopping the Analyzer or Collector.

Therefore, the connection must be through the iBMC port or the mouse and keyboard. According to live network requirements, you can enable the remote root connection function as described in How to Enable or Disable Root Remote Connection. However, enabling this function may cause security risks. After completing installation operations, disable this function immediately.
