中止进程导致系统HANG住

Posted on 2012/03/07 by yangtingkun

以前在11g上碰到过一次类似的情况，由于ALTER SYSTEM KILL SESSION导致资源被完全占用，在一段时间内数据库处于HANG住状态。这次又碰到类似的问题。 简单描述一下问题产生的环境，用户在进行测试，在很短的时间内连续启动了多个应用服务器，导致大量的并发进程同时连接到数据库中，致使数据库服务器CPU利用率一下冲到100%。 由于数据库的这种状态，用户决定中止一些进程来释放服务器上的资源。但是通过kill -9和alter system kill session杀掉大量的会话后，数据库服务器反而处于HANG死状态，这时连sqlplus / as sysdba都无非正常登录。 于是用户继续通过kill -9清除所有非本地连接，到最后所有连接到数据库的非本地连接已经完全被杀掉，而服务器上的CPU资源已经下降，只有Oracle的PMON进程占用了单CPU的50%左右，其他CPU完全空闲。可是此时数据库仍然无非正常登录。 此时只能通过sqlplus –prelim “/ as sysdba”方式登录，然后利用oradebug执行systemstate的dump，查看导致数据库HANG死的原因。 检查SYSTEMSTATE的DUMP文件，发现PMON进程和大量的DEAD进程都在经历library cache: mutex X等待事件。而整个DUMP文件中library cache: mutex X等待事件出现了3000多次。这个等待事件是不正常的。 查询MOS发现果然是bug：Bug 9312879 “library cache: mutex x” waits after killing sessions / PMON slow … Continue reading →

ORA-600(kgeade_is_0)错误

Posted on 2012/02/20 by yangtingkun

一个和并行执行有关的bug。 虽然是并行执行相关，但是报错的并不是Pnnn进程，事实上，实在RAC环境中查询GV$表导致了这个错误。 Wed May 04 15:56:02 EAT 2011 Starting ORACLE instance (normal) LICENSE_MAX_SESSION = 0 LICENSE_SESSIONS_WARNING = 0 Interface TYPE 1 lan900 192.168.194.0 configured FROM OCR FOR USE AS a cluster interconnect Interface TYPE 1 lan901 10.142.194.0 configured FROM OCR … Continue reading →
