本站中文解释

NECT

Oracle视图DBA_HIST_CLUSTER_INTERCONNECT提供了基于时间的簇互连的性能数据的历史记录。这个视图是用来检查簇互连的连接状况，以确保簇互连的性能可满足应用程序的性能需求。

使用此视图，DBA可以监控每个时间段簇互连的性能，如速率、时延、带宽等。DBA可以使用此视图进行性能分析和调优，以确保簇互连的可靠性和性能。另外，DBA也可以使用此视图来诊断和排查与单个簇节点或簇互连有关的问题。

官方英文解释

DBA_HIST_CLUSTER_INTERCON displays information about the devices used by the instance to access the interconnect (that is, communicate with other instances).

Column	Datatype	NULL	Description
`SNAP_ID`	`NUMBER`	`NOT NULL`	Unique snapshot ID
`DBID`	`NUMBER`	`NOT NULL`	Database ID for the snapshot
`INSTANCE_NUMBER`	`NUMBER`	`NOT NULL`	Instance number for the snapshot
`NAME`	`VARCHAR2(256)`	`NOT NULL`	Operating system name of the device
`IP_ADDRESS`	`VARCHAR2(64)`	`NOT NULL`	IP address of the device
`IS_PUBLIC`	`VARCHAR2(3)`		Indicates whether the device is a public interface (`YES`) or a private interface (`NO`) Public interfaces can be listened to by outside applications, which may be a security problem. Oracle recommends using private interfaces for interconnect.
`SOURCE`	`VARCHAR2(31)`		Describes the type of device
`CON_DBID`	`NUMBER`		The database ID of the PDB for the sampled session
`CON_ID`	`NUMBER`		The ID of the container that `CON_DBID` identifies. Possible values include: `0`: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs. `1`: This value is used for rows containing data that pertain to only the root n: Where n is the applicable container ID for the rows containing data
