This script exports your ACL definitions as executable SQL text.

• Run this with SQL*Plus as SYS and store the output.
• From that output, grab just what you need to drop and recreate the offending ACL.
• Edit your script to change the host name.
• Run your edited script to recreate what you need.

ORACLE-BASE - DBA Scripts: network_acls_ddl.sql

Keep in mind that the IFS PL/SQL Access Provider uses an ACL for the database to talk to the application server, so you don’t want to remove everything. You may also have integrations that need these too.
