默认情况下linux是不能分析core文件需要安装内核调试和crash分析工具
从以下网址安装内核调试rpm和 crash
https://oss.oracle.com/ol7/debuginfo/
kernel-uek-debuginfo-4.14.35-1902.3.2.el7uek.x86_64.rpm
kernel-uek-debuginfo-common-4.14.35-1902.3.2.el7uek.x86_64.rpm
yum install crash
安装完毕后检查
[root@ht02 ~]# rpm -qa|grep kernel-uek-debuginfo
kernel-uek-debuginfo-common-4.14.35-1902.3.2.el7uek.x86_64
kernel-uek-debuginfo-4.14.35-1902.3.2.el7uek.x86_64
[root@ht02 ~]# uname -r
4.14.35-1902.3.2.el7uek.x86_64
[root@ht02 ~]# rpm -qa|grep crash
crash-7.2.3-10.el7.x86_64
19c设置cssd、cssdmoniter属性当grid驱逐或者crash时，操作系统生成core文件
开启crash dump
/u01/app/grid/bin/crsctl modify type ora.cssd.type -attr "ATTRIBUTE=REBOOT_OPTS, TYPE=string, DEFAULT_VALUE=,FLAGS=CONFIG" -init
/u01/app/grid/bin/crsctl modify type ora.cssdmonitor.type -attr "ATTRIBUTE=REBOOT_OPTS,TYPE=string, DEFAULT_VALUE=,FLAGS=CONFIG" -init
/u01/app/grid/bin/crsctl modify res ora.cssd -attr "REBOOT_OPTS=CRASHDUMP" -init
/u01/app/grid/bin/crsctl modify res ora.cssdmonitor -attr "REBOOT_OPTS=CRASHDUMP" -init
关闭 crash dump
/u01/app/grid/bin/crsctl modify res ora.cssd -attr "REBOOT_OPTS=" -init
/u01/app/grid/bin/crsctl modify res ora.cssdmonitor -attr "REBOOT_OPTS=" -init
11g开启crash dump 参考mosPre-11.2: Using Diagwait as a diagnostic to get more information for diagnosing Oracle Clusterware Node evictions (Doc ID 559365.1)
[+ASM1]@ht01[/home/grid]$crsctl get css diagwait
CRS-4678: Successful get diagwait 0 for Cluster Synchronization Services.
[root@ht01 ~]# /u01/app/grid/bin/crsctl set css diagwait 13
CRS-4684: Successful set of parameter diagwait to 13 for Cluster Synchronization Services.
[+ASM1]@ht01[/home/grid]$crsctl get css diagwait
CRS-4678: Successful get diagwait 13 for Cluster Synchronization Services
11g关闭 crash dump
crsctl unset css diagwait -force
kill ocssd.bin 进程 cssdmonitor导致操作系统自动重启
