CUBRID HA WIZARD DESIGN

This wizard facilitates the configuration and management of High Availability (HA) for CUBRID databases. Users can add or delete slave hosts, manage database instances, and edit configuration files including `cubrid.conf`, `cubrid_ha.conf`, and `broker.conf`. The tool provides guidance on parameter purposes and recommended values for optimal performance. After configuration, the HA service must be started manually and users are advised to modify the `/etc/hosts` file. Note that HA operates on Linux platforms and has specific requirements for master server detection and CMS support.
