数据库open过程遭遇ORA-1555对应sql语句补充

发表于 2019 年 5 月 8 日 由 惜分飞

在2015年的在数据库open过程中常遇到ORA-01555汇总文章中写过oracle open过程中可能会遇到ORA-01555错误,对应的sql语句.最近的恢复中又遇到两个新的,对其进行补充

在数据库open过程中常遇到ORA-01555汇总

发表于 2015 年 7 月 3 日 由 惜分飞

在数据库open的过程中，select ctime, mtime, stime from obj$ where obj# = :1语句报ORA-01555错误,数据库无法正常open
一般情况下会报某个回滚段,但是这里ORA-01555: snapshot too old: rollback segment number 0 with name “SYSTEM” too small这里直接报了system(系统回滚段),属于少见情况

在数据库open的过程中,select increment$,minvalue,maxvalue,cycle#,order$,cache,highwater,audit$,flags from seq$ where obj#=:1语句上报ORA-01555,导致数据库open失败
ORA-01555


在数据库open过程中,select /*+ rule */ name,file#,block#,status$,user#,undosqn,xactsqn,scnbas,scnwrp,DECODE(inst#,0,NULL,inst#),ts#,spare1 from undo$ where us#=:1语句导致数据库open失败.

出现这类问题,一般是由于obj$,seq$,undo$等基表上对象scn大于数据库当前scn或者是由于这些表上有事务未提交,出现上述两种情况,数据库需要找对应的undo的回滚段中记录,而此时对应的回滚段异常(或者是由于redo未进行正常前滚,导致上述对象或者回滚段记录不正常),从而出现类似情况,一般出现此类情况,可以通过10046定位到block，然后故障原因采用bbed修改scn或者bbed提交事务来解决此类问题.
最近两年的恢复中又遇到一些ora-00704 ora-00604 ora-01555的错误,导致数据库无法正常open,对其进行补充,具体参见:数据库open过程遭遇ORA-1555对应sql语句补充
