11.2通過資料庫鏈呼叫10.2過程報錯

錯誤可以通過下面的例子重現：

-bash-3.2$ sqlplus / as sysdba

SQL> create user test identified by test default tablespace users;

User created.

首先在10.2.0.1環境中建立一個儲存過程。

SQL> create database link xe connect to test identified by test using '192.168.0.20:1522/XE';

Database link created.

在11.2中呼叫這個儲存過程報錯，嘗試使用同義詞或動態SQL，都無法繞過這個錯誤：

SQL> create synonym s1 for p1@xe;

Synonym created.

SQL> exec s1
BEGIN s1; END;

在metalink文件Bug 4511371中描述了這個問題：ORA-6544 / ORA-4052 using PLSQL between 10g and 11g。根據文件描述，在10.2.0.1中通過資料庫鏈訪問11.2的過程也會出現同樣的錯誤，而解決方法除了升級到10.2.0.2及以上版本外，沒有其他的解決方法。
