开启Oracle ACL权限

执行以下语句

BEGIN  DBMS_NETWORK_ACL_ADMIN.create_acl (    acl          => 'open_acl_file.xml',     description  =&gtoracle账号; 'Open ACL File',    principal    => '目标Oracle账号',    is_grant     => TRUE,     privilege    => 'connect',    start_date   => SYSTIMESTAMP,    end_date     => NULL);  DBMS_NETWORK_ACL_ADMIN.assign_acl (    acl         => 'open_acl_file.xml',    host        => '*',     lower_port  => 1,    upper_port  => 9999);   COMMIT;END;/

这个权限比较大：因为host是*，端口不限。在正式使用时，可以缩小权限。比如第二段改成：

dbms_network_acl_admin.assign_acl(acl => 'open_acl_file.xml',    host=> ' 具体IP地址 ',    lower_port => 8080,    upper_port => 8080);END
