在linux 7.9的系统中安装oracle 19c的rac,在第二个节点执行root.sh报以下错误

标题：重现sql执行计划SYS_OP_C2C隐式转换

作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

在一次的sql优化中,遇到SYS_OP_C2C函数,通过分析是由于一个表的varchar2和另外一个表的nvarchar2列进行关联导致,通过以下简单使用进行重现.对于这个问题,如果需要使用index,需要创建SYS_OP_C2C的函数index,或者把列类型修改一致.

SQL> create user xff identified by oracle;

用户已创建。

SQL> grant dba to xff;

授权成功。

SQL> create table xff.t1(id number,name varchar2(100));

表已创建。

SQL> insert into xff.t1 select  object_id,object_name from dba_objects;

已创建 89932 行。

SQL> commit;

提交完成。

SQL> create table xff.t2(id number,name nvarchar2(100));

表已创建。

SQL> insert into xff.t2 select  object_id,object_name from dba_objects;

已创建 89933 行。

SQL> commit;

提交完成。


SQL> exec dbms_stats.gather_table_stats('XFF','T1',cascade=>true);

PL/SQL 过程已成功完成。

SQL> exec dbms_stats.gather_table_stats('XFF','T2',cascade=>true);

PL/SQL 过程已成功完成。


SQL> set autot on
SQL>  select count(1) from xff.t1, xff.t2 where t1.name=t2.name;

  COUNT(1)

还有一种情况也可能发生该转换,比如使用dblink的访问远程库,本地库和远程库字符集不一致.参考:SQL Statements Performed Across Database Links run Slowly. Explain Plan Shows Function SYS_OP_C2C has been Applied to Predicates, and Query uses a Full Table Scan. (Doc ID 2010872.1)

对于安全公司对oracle漏洞扫描的结果的准确性一直不太认可,前几天有客户linux 平台11.2.0.4的数据库打上了210420的patch,结果xx安全厂商扫描之后,依旧有大量安全漏洞,我随机对其中的两个高危漏洞进行分析,结果发现主要有:已经修复的漏洞继续报,漏洞对应数据库版本和实际数据库不符
数据库库的补丁信息
20210811190805

已经修复的漏洞依旧报
20210811190838
20210811190844
这里比较明显CVE-2018-3110漏洞oracle在18年7月份的补丁中已经修复,而我们这个是21年04月的补丁包含了该patch,已经修复了该问题
直接报漏洞和数据库版本不匹配
20210811190828
CVE-2016-1000031这个安全漏洞根本只是在12.2+版本中才有,他直接给客户的11204版本提示高危漏洞
