Oracle 视图 DBA_HIST_REPLICATION_TBL_STATS 官方解释，作用，如何使用详细说明

网络编程 Oracle 视图 DBA_HIST_REPLICATION_TBL_STATS 官方解释，作用，如何使用详细说明 10-18

本站中文解释

Oracle视图DBA_HIST_REPLICATION_TBL_STATS用于确定复制传输的表的状态。可以在ASE平台的维护工作中查看表之间复制的情况，以检测传输状况是否健康，明确大量传输不健康的表。

它还具有查询复制运行状况的功能，可以查看每张表上一次成功复制事件发生时间，以及每个表上复制事务累计数量。在N和P两方数据库之间有很多数据传输时，这样就可以查出哪些表的传输健康，哪些不健康。

使用Oracle视图DBA_HIST_REPLICATION_TBL_STATS时，可以使用联接操作查询其中的信息，也可以通过DBA_HIST_SNAPSHOT视图查询基于SNAPSHOT的信息。

如下所示的查询可以检索DBA_HIST_REPLICATION_TBL_STATS视图中的数据：

SELECT TABLE_NAME，SNAP_ID，TIME ，TOTAL_UPDATES
FROM
DBA_HIST_REPLICATION_TBL_STATS，
DBA_HIST_SNAPSHOT
WHERE
DBA_HIST_REPLICATION_TBL_STATS.SNAP_ID =
DBA_HIST_SNAPSHOT.SNAP_ID;

官方英文解释

DBA_HIST_REPLICATION_TBL_STATS displays replication table statistics for Oracle GoldenGate and XStream sessions. This view is intended for use with Automatic Workload Repository (AWR).

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
`APPLY_NAME`	`VARCHAR2(128)`	`NOT NULL`	Name of the apply process
`TABLE_NAME`	`VARCHAR2(128)`	`NOT NULL`	Name of the table
`TABLE_OWNER`	`VARCHAR2(128)`	`NOT NULL`	Owner of the table
`SESSION_MODULE`	`VARCHAR2(64)`	`NOT NULL`	Session module. Valid values: XStream GoldenGate
`TOTAL_INSERTS`	`NUMBER`		Number of insert operations on this table processed by this apply server
`TOTAL_UPDATES`	`NUMBER`		Number of update operations on this table processed by this apply server
`TOTAL_DELETES`	`NUMBER`		Number of delete operations on this table processed by this apply server
`CDR_SUCCESSFUL`	`NUMBER`		Number of successfully resolved conflicts
`CDR_FAILED`	`NUMBER`		Number of conflicts that could not be resolved due to an error during resolution
`REPERR_CNT`	`NUMBER`		The total number of errors for the replication operation
`HANDLE_COLLISIONS`	`NUMBER`		Number of collisions on this table handled by this apply server
`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
