Data Types
TYPE aclid_table IS TABLE OF NUMBER INDEX BY BINARY INTEGER;
Adds a privilege to grant or deny the network access to the user in an access control list (ACL)
Deprecated in 12.2: Use APPEND_HOST_ACE
dbms_network_acl_admin.add_privilege(
acl IN VARCHAR2,
principal IN VARCHAR2,
is_grant IN BOOLEAN,
privilege IN VARCHAR2,
position IN PLS_INTEGER DEFAULT NULL,
start_date IN TIMESTAMP WITH TIMESTAMP DEFAULT NULL,
end_date IN TIMESTAMP WITH TIMESTAMP DEFAULT NULL);
Append an access control entry (ACE) to the access control list (ACL) of a network host.
The ACL controls access to the given host from the database and the ACE specifies the privileges granted to or denied from the specified principal.
dbms_network_acl_admin.append_host_ace(
host IN VARCHAR2,
lower_port in PLS_INTEGER DEFAULT NULL,
upper_port in PLS_INTEGER DEFAULT NULL,
ace in xs$ace_type);
Append access control entries (ACE) of an access control list (ACL) to the ACL of a network host
dbms_network_acl_admin.append_host_acl(
host IN VARCHAR2,
lower_port in PLS_INTEGER DEFAULT NULL,
upper_port in PLS_INTEGER DEFAULT NULL,
acl IN VARCHAR2);
Append an access control entry (ACE) to the access control list (ACL) of a wallet.
The ACL controls access to the given wallet from the database and the ACE specifies the privileges granted to or denied from the specified principal.
dbms_network_acl_admin.append_wallet_ace(
wallet_path IN VARCHAR2,
ace in xs$ace_type);
Creates an access
control list (ACL) with an initial privilege setting
Deprecated in 12.2: APPEND_HOST_ACE
dbms_network_acl_admin.create_acl(
acl IN VARCHAR2,
description IN VARCHAR2,
principal IN VARCHAR2,
is_grant IN BOOLEAN,
privilege IN VARCHAR2,
start_date IN TIMESTAMP WITH TIMEZONE DEFAULT NULL,
end_date IN TIMESTAMP WITH TIMEZONE DEFAULT NULL );

Deletes a privilege in an access control list (ACL)
Deprecated in 12.2: Use REMOVE_HOST_ACE
dbms_network_acl_admin.delete_privilege(
acl IN VARCHAR2,
principal IN VARCHAR2,
is_grant IN BOOLEAN DEFAULT NULL,

Remove privileges from access control entries (ACE) in the access control list (ACL) of a network host matching the given ACE
dbms_network_acl_admin.remove_host_ace(
host IN VARCHAR2,
lower_port IN PLS_INTEGER DEFAULT NULL,
upper_port IN PLS_INTEGER DEFAULT NULL,
ace IN xs$ace_type,
remove_empty_acl IN BOOLEAN DEFAULT FALSE);
Set the access control list (ACL) of a network host which controls access to the host from the database
dbms_network_acl_admin.set_host_acl(
host IN VARCHAR2,
lower_port IN PLS_INTEGER DEFAULT NULL,
upper_port IN PLS_INTEGER DEFAULT NULL,
acl IN VARCHAR2);
