<p>最近有客户遭遇非系统回滚段报ORA-01558的故障,类似:ORA-01558: out of transaction ID&#8217;s in rollback segment _SYSSMU4_1254879796$,在之前的恢复case中遇到两次system rollback报ORA-01558而不能正常启动的案例.(<a href="https://www.xifenfei.com/2024/09/ora-01558.html" title="ORA-01092 ORA-00604 ORA-01558故障处理" rel="noopener" target="_blank">ORA-01092 ORA-00604 ORA-01558故障处理</a>和<a href="https://www.xifenfei.com/2022/09/ora-01558-recovery.html" title="ORA-01558: out of transaction ID’s in rollback segment SYSTEM" rel="noopener" target="_blank">ORA-01558: out of transaction ID’s in rollback segment SYSTEM</a>),这次是业务回滚段,出来起来相对比较简单,直接重建该回滚段所在undo表空间即可.遭遇该问题的主要原因是由于19c rac中由于禁用drm,设置了_gc_undo_affinity=FALSE参数导致.<br />

还有一个类似bug,需要注意:Bug 19700135  ORA-600 [4187] when the undo segment wrap# is close to the max value of 0xffffffff,主要影响版本为：<br />
<img src="https://www.xifenfei.com/wp-content/uploads/2025/02/1.png" alt="1" width="671" height="285" class="alignleft size-full wp-image-11193" /><br />
<hr />
关于该bug的描述</p>
<pre class="brush: bash; title: ; notranslate">
ORA-600 [4187] can occur for undo segments where wrap# is close to the max value of 0xffffffff (KSQNMAXVAL).
This normally affects databases with high transaction rate that have existed for a relatively long time.
 
To identify undo segments causing the above error and others that may potentially cause it 
in the future, run the next query:
 
 select b.segment_name, b.tablespace_name 
         ,a.ktuxeusn &quot;Undo Segment Number&quot;
         ,a.ktuxeslt &quot;Slot&quot;
         ,a.ktuxesqn &quot;Wrap#&quot;
   from  x$ktuxe a, dba_rollback_segs b
   where a.ktuxesqn &gt; -429496730 and a.ktuxesqn &lt; 0
       and a.ktuxeusn = b.segment_id;
 
Then drop the undo segments or the undo tablespace from the output above.
 
With this fix in place an error ORA-1558 is eventually produced for the affected undo segment
which still requires dropping the undo segment:
  ORA-1558 &quot;out of transaction ID's in rollback segment %s&quot;
   Cause: All the available transaction id's have been used
   Action: Shutdown the instance and restart using other rollback segment(s),
                then drop the rollback segment that has no more transaction id's.

<p>由于客户遇到故障之后,第一时间保护了现场,没有进行二次破坏,使用bbed进行修改block,实现完美恢复.<br />
以前有过一次在11.2.0.4的环境中恢复的同样案例:<a href="https://www.xifenfei.com/2022/09/ora-01558-recovery.html" title="ORA-01558: out of transaction ID’s in rollback segment SYSTEM" rel="noopener" target="_blank">ORA-01558: out of transaction ID’s in rollback segment SYSTEM</a><br />
通过查询mos,确认类似Bug 19700135 &#8211; ORA-600 [4187] when the undo segment wrap# is close to the max value of 0xffffffff (Doc ID 19700135.8)<br />
<img src="https://www.xifenfei.com/wp-content/uploads/2024/09/bug-19700135.jpg" alt="bug-19700135" width="1245" height="610" class="alignleft size-full wp-image-11006" /></p>
<pre class="brush: bash; title: ; notranslate">
Description
ORA-600 [4187] can occur for undo segments where wrap# is close to the max value of 0xffffffff (KSQNMAXVAL).
This normally affects databases with high transaction rate that have existed for a relatively long time.
 
To identify undo segments causing the above error and others that may potentially cause it 
in the future, run the next query:
 
 select b.segment_name, b.tablespace_name 
         ,a.ktuxeusn &quot;Undo Segment Number&quot;
         ,a.ktuxeslt &quot;Slot&quot;
         ,a.ktuxesqn &quot;Wrap#&quot;
   from  x$ktuxe a, dba_rollback_segs b
   where a.ktuxesqn &gt; -429496730 and a.ktuxesqn &lt; 0
       and a.ktuxeusn = b.segment_id;
 
Then drop the undo segments or the undo tablespace from the output above.
 
With this fix in place an error ORA-1558 is eventually produced for the affected undo segment
which still requires dropping the undo segment:
  ORA-1558 &quot;out of transaction ID's in rollback segment %s&quot;
   Cause: All the available transaction id's have been used
   Action: Shutdown the instance and restart using other rollback segment(s),
                then drop the rollback segment that has no more transaction id's.
 
Workaround
 Once the ORA-600 [4187] is produced, drop the affected undo segment or undo tablespace.

<p>由于本次故障是在system的rollback回滚段上,无法删除该回滚段.所以处理起来比较棘手.</p>
