oracle扩展dblink数。

【标记】在进行数据迁移时；出现

Compilation errors for PROCEDURE ZDGAME.GFF_FETCH_MZR_LOG

Error: ORA-04052: error occurred when looking up remote object mf_game_db.g_account@MZRA_ALL
       ORA-00604: error occurred at recursive SQL level 1
       ORA-02020: too many database links in use
Line: 1
Text: CREATE OR REPLACE PROCEDURE gff_fetch_mzr_log(v_yesterday VARCHAR2) IS　　

单独通过dblink去查是OK；但是编译存储过程会出现上面问题。问题出现在参数上面

下面是解决方案：

[oracle@bjmxy_server12_17 admin]$ sqlplus / as sysdba
