Why Do I Fail to Modify the Specifications for a DCS Instance?
Updated on 2022-08-10 GMT+08:00
Why Do I Fail to Modify the Specifications for a DCS Instance?
- Check whether other tasks are running.
Specifications of a DCS instance cannot be modified if another task of the instance is still running. For example, you cannot delete or scale up an instance while it is being restarted. Likewise, you cannot delete an instance while it is being scaled up.
If the specification modification fails, try again later. If it fails again, contact technical support.
- When changing a master/standby instance to the Proxy Cluster type, check whether data exists in DBs other than DB0. Specification modification will fail if a DB other than DB0 contains data.
A master/standby instance can be changed to the Proxy Cluster type when data exists only in DB0.
