Changing CPU and Memory Specifications¶
Scenarios¶
You can change the CPU and memory specifications of a GaussDB instance if needed.
Precautions¶
By default, the specifications cannot be reduced. If you need to reduce the specifications, contact customer service.
Before you change the instance specifications, ensure that the instance is available. If the instance or node is abnormal, or the storage space is full, you cannot perform this operation.
During the specification change for an HA (1 primary + 2 standby) instance, a primary/standby failover is triggered. During the failover, services are interrupted for about 1 minute.
After you change vCPUs and memory, the DB instances will be rebooted and service will be interrupted. You are advised to perform this operation during off-peak hours.
