Server pool {0} is internally managed as part of administrator-managed database configuration and therefore cannot be modified directly via srvpool object.
Cause
An attempt was made to alter configuration of an internally managed server pool that is hosting an administrator-managed configuration.
Action
Do not modify this server pool via srvpool object directly. Instead use the command 'srvctl add/remove instance' or use the command 'srvctl modify database/service' to alter this server pool's configuration.
