最近发现一个很奇怪的问题：
创建了一个DB_LINK连接另一个Oracle数据库。
select * from tablename@dblinkname;
单句执行没问题，但是把这句SQL写到存储过程内：
create or replace procedure prc_test
is
begin
insert into test
select * from tablename@dblinkname;
commit;
end;
就发生如下错误,存储过程编译不通过：
报错如下：PACKAGE BODY SKSKJ.PKG_TS 编译错误
错误：PL/SQL:
ORA-04052: error occurred when looking up remote object DZDZ_123.SM123@DZDZ123
ORA-00604: error occurred at recursive SQL level 1
ORA-03106: fatal two-task communication protocol error
ORA-02063: preceding line from DZDZ_SJTS
行：32
文本：insert into sm123@DZDZ123
也不是所有的数据库都有这样的问题。
哪位大侠遇到过这样的问题，能否给个解决方案？非常感谢！
附：创建dblink的脚本：
-- Drop existing database link
drop database link dblink1;
-- Create database link
create database link dblink1
connect to username123 identified by passwd123
using ‘(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.*.*)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = 123)
)
)‘;
drop synonym test;
create synonym test for test@dblink1;
--metalink上解决问题方法，打上对应的补丁就解决了。
