ORA-24266
Cause
An API in DBMS_NETWORK_ACL_ADMIN PL/SQL package was invoked with a PRIVATE_TARGET argument value that was inconsistent with the host resolution type of the network host.
Action
If you were setting the access control list (ACL) or appending an access control entry (ACE) to the access control list (ACL) of a network host using an API in DBMS_NETWORK_ACL_ADMIN PL/SQL package, please query the DBA_HOST_ACLS dictionary view for the network host to confirm whether the host name is to be resolved privately. If PRIVATE_TARGET column field for the host is set to TRUE, the DBMS_NETWORK_ACL_ADMIN API call needs to be executed with PRIVATE_TARGET argument passed as TRUE. Otherwise avoid specifying PRIVATE_TARGET argument as TRUE, if PRIVATE_TARGET column field for the host is set to FALSE.
