Note
This view is available starting with V4.2.0.
Purpose
This view displays the GTS/STS values of the tenant clock service, the node information where the clock service is located, and the clock source type.
The following distinctions apply based on the database:
- For the primary database, it displays the current GTS value that has been allocated to the primary database.
- For the standby database, it displays the current readable point (STS) value of the standby database.
The following distinctions apply based on the tenant:
- In the system tenant, you can view the clocks of all tenants.
- In a user tenant, you can only view the clocks of the current tenant.
