PRCS-01129
nodes {0} of the reader farm server pool {1} do not have LEAF active CSS roles
Cause
An attempt to add or modify a service was rejected because the specified server pool did not have nodes with ACTIVE_CSS_ROLE=LEAF as required for the policy-managed databases using reader farm services.
Action
Modify the server pool to use nodes that have LEAF active Oracle Cluster Synchronization Services (CSS) roles using 'srvctl modify serverpool -category' and retry the operation.
