This section describes the solidDB® system events. These events are provided with solidDB® to allow programs to be notified when certain actions occur. You can use these events to monitor the progress of activities such as synchronization between master and replica databases.
The system events follow most of the same rules as user-defined events.
Because these events are pre-defined, you do not create them. Furthermore, you cannot post system events; you can only wait on system events.
Most system events have the same five parameters:
▪ename: The event name.
▪postsrvtime: The time that the server posted the event.
▪uid: The user ID (if applicable).
▪numdatainfo: Miscellaneous numeric data — the exact meaning depends upon the event. For example, the event SYS_EVENT_BACKUP is posted both when a backup is started and when a backup is completed. The value in the numdatainfo parameter indicates which case applies — i.e. whether the backup has just started or has just completed. This parameter may be NULL if there is no numeric data.
▪textdata: Miscellaneous text data — the exact meaning depends upon the event. This parameter may be NULL if there is no numeric data.
