官方英文解释
DBA_SR_GRP_STATUS_ALL provides information on the refresh operations on the synchronous refresh groups in the database.
A refresh operation is also called a run, and it has two phases: PREPARE_REFRESH and EXECUTE_REFRESH. These phases are controlled using the DBMS_SYNC_REFRESH package.
Each row in this view provides information on a run of a group, identified by its GROUP_ID. The view contains information on the status of the objects of both current and past runs of both current and defunct synchronous refresh groups. Therefore, this view can be used to examine the history of synchronous refresh operations.
The current run of a group is the most recent run of a group; a current group is a currently valid group, which is capable of being refreshed. A group becomes defunct when it is unregistered for any reason, either explicitly by the user or implicitly as a side-effect when the user registers materialized views related to the materialized views in the group.
To view the status of refresh operations for the most recent runs of only the current groups, use the DBA_SR_GRP_STATUS view.
