ERROR: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Enter user-name:
@zjcnew If the pod is evicted, then the listener service running in that pod will also be down causing ORA-12514. Can you share more details about you cluster configuration, deployment info etc (using kubectl describe) to find out why this pod eviction is happening ?
