Oracle database backups fail with RMAN error 06403 "Could not obtain a fully authorized session" and Oracle error ORA-01034 "ORACLE not available Recovery Manager complete"
INBOUND_CONNECT_TIMEOUT_listener_name = <timeout value in seconds>
Note: Once this setting is in place, it is necessary to restart the listener or the database to apply the changes. The INBOUND_CONNECT_TIMEOUT parameter also exists for Oracle configuration file SQLNET.ORA. It might be necessary to use the parameter in both places in order to overcome the problem.
Please consult the Oracle Database Net services Reference Guide for additional information and guidance for the chosen timeout value.
