错误 ORA-00942 运行 DBMS_COMPARISON.CONVERGE 子程序

Error ORA-00942 running DBMS_COMPARISON.CONVERGE subprogram

我收到 ORA-00942 - table 或视图不存在 - 当我 运行 使用 DBMS_COMPARISON 包同步两个 table 的存储过程时出错] 有两种不同的模式。

我的大概是这样的:

remote table        local comparison     local table    
DB1.PRODUCTS        DB2.PRODUCTS_CMP     DB2.PRODUCTS

这是本地 DB2 程序:

create or replace PROCEDURE SYNC_SINGLE AS
          L_SCAN_INFO         SYS.DBMS_COMPARISON.COMPARISON_TYPE;
          L_RESULT            BOOLEAN;   
          L_COMPNAME          VARCHAR2(30);
BEGIN
          L_COMPNAME:='PRODUCT_CMP';
          
          SYS.DBMS_COMPARISON.PURGE_COMPARISON(
                   COMPARISON_NAME => L_COMPNAME
          );

          L_RESULT := 
                    SYS.DBMS_COMPARISON.COMPARE (
                    COMPARISON_NAME => L_COMPNAME,
                    SCAN_INFO       => L_SCAN_INFO,
                    PERFORM_ROW_DIF => TRUE
          );

          FOR ROW_ID IN (
                    SELECT    SCAN_ID
                    FROM      USER_COMPARISON_SCAN_SUMMARY
                    WHERE     COMPARISON_NAME = L_COMPNAME
                              AND STATUS = 'BUCKET DIF'
          )
          LOOP      
                    SYS.DBMS_COMPARISON.CONVERGE (
                              COMPARISON_NAME  => L_COMPNAME,
                              SCAN_ID          => ROW_ID.SCAN_ID,
                              SCAN_INFO        => L_SCAN_INFO,
                              CONVERGE_OPTIONS => SYS.DBMS_COMPARISON.CMP_CONVERGE_REMOTE_WINS, 
                              PERFORM_COMMIT   => FALSE
                    );
          END LOOP ROW_ID;

          SYS.DBMS_COMPARISON.PURGE_COMPARISON(
                   COMPARISON_NAME => L_COMPNAME
          );

END SYNC_SINGLE;

程序以这些错误结束:

ORA-00942: table or view does not exist
ORA-06512: a "SYS.DBMS_COMPARISON", line 734
ORA-06512: a "SYS.DBMS_COMPARISON", line 5964
ORA-06512: a "SYS.DBMS_COMPARISON", line 682
ORA-06512: a "DB2.SYNC_SINGLE", line 26
ORA-06512: a "DB2.SYNC_SINGLE", line 26
ORA-06512: a line 2

我想这里存在权限问题,但我不知道是什么问题。用户 SYS 已获得本地 table DB2.PRODUCTS 授予的所有权限。 此外,我还有其他 tables 在我以相同方式同步的相同模式上,对于那些 tables 一切都很好。查看 tables SYS.COMPARISON$ 和 SYS.COMPARISON_COL$ 一切似乎都配置正确。

任何人都可以帮助建议我应该检查什么吗?

我找到了原因:程序声明中缺少 AUTHID CURRENT_USER

create or replace PROCEDURE SYNC_SINGLE AUTHID CURRENT_USER AS
