RAC
调试中的一个黄金规则
1.请始终确保各个节点具有完全相同的
系统时间，这样才能实现以下目标：
– 便于进行
日志信息分析 – 确保读取 GV$
视图时获得准确结果
– 避免
实例被过早逐出
2. 最好的
建议是使用
网络时间协议对各节点进行
同步。

诊断收集脚本
1.用于收集所有重要日志文件的脚本应满足以下条件：
– 必须以 root 身份执行
– 位于 $ORA_CRS_HOME/bin/ 中
– 名为 diagcollection.pl
2.将在本地目录中生成以下文件：
– basData_.tar.gz
- coreData_.tar.gz
– crsData _. tar.gz
– ocrData _. tar.gz
– oraData _. tar.gz
示例：
root@rac1 /oracle/backup$ /u01/crs1020/bin/diagcollection.pl -collect

The following CRS diagnostic archives will be created in the local directory.
crsData_rac1.gz -> logs,traces and cores from CRS home
ocrData_rac1.gz -> ocrdump, ocrcheck etc
coreData_rac1.gz -> contents of CRS core files in text format
