解决AIX 6.1上Oracle 11G R2 osysmond.bin进程core dump问题

 

 

从您提供的信息中，我能够确认，触发core dump的是 我们用于诊断所使用到的 crfmond 进程触发的。

详细的CHM介绍，我们最近正好有个中文Oracle 官方社区帖子在讨论，供您 参考

另外，对于该core dump 不会对您正常使用造成任何影响。不过，如果您如果希望规避该问题，可以考虑

1. 手动停止该服务

2. 应用最新的 11.2.0.3 PSU 补丁集，参考
RAC PATCHING QUICK REF: Applying CRS PSU, CRS Bundle, GI PSU, Windows Bundles 10.2 - 11.2 (Doc ID 1446371.1)

3. 检查您当前的 系统mount -l 输出，看是否有超出255个mount point的配置。

 

 

请参考
https://blogs.oracle.com/Database4CN/entry/11gr2_%E6%96%B0%E7%89%B9%E6%80%A7_oracle_cluster_health

用root用户：
$GRID_HOME/bin/crsctl stop res ora.crf -init

来停止该服务。停止该服务，会解决您遇到的 core dump 问题。

停止之后，建议您部署 OS Watcher 工具来替代监控操作系统资源信息
请参考
Note:301137.1 OS Watcher Black Box User Guide

For example:

1. To start the the OSW:

nohup ./startOSWbb.sh 15 96 &

==>It will collect data at 15 second intervals, and remain the last 96 hours of data to archive files.

==>Make sure you have enough space to store the OSW output files.
2. Please manually configure the private Network statistics collection for OSWatcher by referring to file –Exampleprivate.net in the OSW folder.
