数据冲突Statspack ORA-00001 unique constraint violated错误的解决

这两天个人几篇文章介绍了改数据冲突的文章. 关联文章的地址

    我这里分两部分，这个问题在网上查到一个解决方案，从mos里又看到更加全的。

    

    ============================转载部分===========================================

    ORA-00001: unique constraint (PERFSTAT.STATS$SQL_SUMMARY_PK) violated

    ORA-06512: at "PERFSTAT.STATSPACK", line 1361

    ORA-06512: at "PERFSTAT.STATSPACK", line 2471

    ORA-06512: at "PERFSTAT.STATSPACK", line 91

    ORA-06512: at line 1

    这个错误此前从未遇到，但是既然是主键冲突，那肯定是存在重复主键的数据。

    肯定能临时解决问题方法就是临时禁用独一约束检查:

    ALTER TABLE PERFSTAT.STATS$SQL_SUMMARY 

    MODIFY CONSTRAINT STATS$SQL_SUMMARY_PK DISABLE NOVALIDATE;

    然后视察数据来发现根本问题，最后彻底解决之。

    到Metalink搜索了一下，发现存在一个相干Bug，Bug号为:2784796.

    在设置了cursor_sharing为similar或者force以后，可能触发此Bug，导致主键冲突。

    此bug据说在Oracle10g中已经修正。

    execute statspack.snap

    或
BEGIN statspack.snap; END;

    执行创立snap的时候报错

    ERRORat line 1:
ORA-00001 : unique constraint (PERFSTAT.STATS$SQL_SUMMARY_PK) violated
ORA-06512 : at "PERFSTAT.STATSPACK",line 1361
ORA-06512 : at "PERFSTAT.STATSPACK", line 2442
ORA-06512 : at "PERFSTAT.STATSPACK", line 91
ORA-06512 : at line 1

    从MOS上看，这个bug在9.0.1.4 到 9.2的一个bug

    解决方法如下：

    sqlplus " / as sysdba" 
SQL> spool run_statspack.txt 
SQL> create or replace view STATS$V_$SQLXS as 
select max(sql_text) sql_text 
, sum(sharable_mem) sharable_mem

, sum(loaded_versions) loaded_versions 
, sum(fetches) fetches

, sum(loads) loads 
, sum(invalidations) invalidations 
, sum(parse_calls) parse_calls 
, sum(disk_reads)disk_reads 
, sum(buffer_gets) buffer_gets 
, sum(rows_processed) rows_processed

from v$sql 
where ( plan_hash_value > 0 
or executions > 0 
or parse_calls > 0 
or disk_reads> 0 
or buffer_gets > 0) 
group by hash_value, address; 
SQL> select owner,object_name from dba_objects wherestatus ='INVALID'; 
SQL> @?/rdbms/admin/utlrp 
SQL> select owner,object_name from dba_objects where status ='INVALID';
SQL> conn perfstat/perfstat_password 
SQL> execute statspack.snap(i_snap_level=>5); 
SQL> spool off; 

    每日一道理
心的本色该是如此。成，如朗月照花，深潭微澜，不论顺逆，不论成败的超然，是扬鞭策马，登高临远的驿站；败，仍滴水穿石，汇流入海，有穷且益坚，不坠青云的傲岸，有“将相本无主，男儿当自强”的倔强。荣，江山依旧，风采犹然，恰沧海巫山，熟视岁月如流，浮华万千，不屑过眼烟云；辱，胯下韩信，雪底苍松，宛若羽化之仙，知退一步，海阔天空，不肯因噎废食。

文章结束给大家分享下程序员的一些笑话语录： 人工智能今天的发展水平：8乘8的国际象棋盘其实是一个体现思维与创意的强大媒介。象棋里蕴含了天文数字般的变化。卡斯帕罗夫指出，国际象棋的合法棋步共有1040。在棋局里每算度八步棋，里面蕴含的变化就已经超过银河系里的繁星总数。而地球上很少有任何数量达到这个级别。在金融危机之前，全世界的财富总和大约是1014人民币，而地球人口只有1010。棋盘上，所有可能的棋局总数达到10120，这超过了宇宙里所有原子的总数！经典语录网
