Applies to:Oracle Net Services - Version 220.127.116.11 and later
Information in this document applies to any platform.
Connections are intermittently working.
Work for all connections and then suddenly end with "account locked"
Local connection to the same DB does not show this user account is locked and access works.
Sometimes the connection may fail with ORA-1033 but the Database is mounted and open.
Listener services may show "additional" services or handlers
