In OceanBase Database V4.x, internal tables and virtual tables are greatly modified and more views are provided to show system information. In OceanBase Database V4.x, all internal information is displayed in views. Views in different versions are compatible and the information displayed in views is clearer.
For example, the __all_tenant_meta_table table is used in earlier versions to record the location information of each partition. In OceanBase Database V4.x, location information is no longer separately provided for partitions. The location of a partition depends on the location of the log stream to which the partition belongs. You can query the DBA_OB_LS_LOCATIONS view for location information about log streams. The __all_zone table is used in earlier versions to record the major compaction status of clusters. OceanBase Database V4.x stores only the zone and region information of clusters in the __all_zone table in the sys tenant, and stores the major compaction status information in dedicated internal tables. You can query the DBA_OB_MAJOR_COMPACTION view for the overall major compaction status, and query the DBA_OB_ZONE_MAJOR_COMPACTION view for the major compaction status of each zone. In earlier versions, major compactions are performed at the cluster level. In OceanBase Database V4.x, major compactions can be performed at the tenant level. Therefore, you can query the DBA_OB_MAJOR_COMPACTION and DBA_OB_ZONE_MAJOR_COMPACTION views for the major compaction status of tenants.
In OceanBase Database V4.x, the following modifications are made to the existing views based on the view definition specifications:
- Unnecessary views are removed.
- All view names are prefixed with
OB_. - All view names and column names are converted to uppercase letters.
- A tenant-level view displays the data of the current tenant in a user tenant, and displays the data of all tenants in the
systenant.

- In versions earlier than OceanBase Database V4.0, names of some self-managed views are not prefixed with
OB_*, such asv$plan_cache_statandv$obrpc_outgoing. - In OceanBase Database V4.0 and later, all view names are prefixed with
OB_*, such asV$OB_PLAN_CACHE_STATandV$OB_RPC_OUTGOING.
