最近發現一個很奇怪的問題：
創建了一個DB_LINK連接另一個Oracle數據庫。
select * from tablename@dblinkname;
單句執行沒問題，但是把這句SQL寫到存儲過程內：
create or replace procedure prc_test
is
begin
insert into test
select * from tablename@dblinkname;
commit;
end;
就發生如下錯誤,存儲過程編譯不通過：
報錯如下：PACKAGE BODY SKSKJ.PKG_TS 編譯錯誤
錯誤：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
也不是所有的數據庫都有這樣的問題。
哪位大俠遇到過這樣的問題，能否給個解決方案？非常感謝！
附：創建dblink的腳本：
-- 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上解決問題方法，打上對應的補丁就解決了。
