下面是模拟主机OCSSD.LOG进程HANG住导致主机重启
1，环境介绍
|
[root@cisser2 ~]# crsctl query crs activeversion CRS active version on the cluster is [10.2.0.5.0] [root@cisser2 ~]# lsb_release -a LSB Version: :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch Distributor ID: RedHatEnterpriseServer Description: Red Hat Enterprise Linux Server release 5.11 (Tikanga) Release: 5.11 Codename: Tikanga |
2，手动暂停OCSSD进程
|
[root@cisser1 ~]# ps -ef|grep d.bin oracle 4666 4665 0 11:23 ? 00:00:00 /oracle/app/oracle/product/10.2.0/crs_1/bin/evmd.bin root 4746 4063 0 11:23 ? 00:00:00 /oracle/app/oracle/product/10.2.0/crs_1/bin/crsd.bin reboot root 5258 4874 0 11:23 ? 00:00:00 /oracle/app/oracle/product/10.2.0/crs_1/bin/oprocd.bin run -t 1000 -m 500 -f oracle 5348 4903 0 11:23 ? 00:00:00 /oracle/app/oracle/product/10.2.0/crs_1/bin/ocssd.bin root 14621 13718 0 11:44 pts/1 00:00:00 grep d.bin [root@cisser1 ~]# kill -19 5348 |
30S后会生成下面的日志
3，主机messages日志
|
Mar 29 11:45:23 cisser1 logger: Oracle clsomon failed with fatal status 13. |
这里看到状态为13，这里由于status代码不通，可能出错的原因不通，下面是常见的代码说明。
|
/* 10-39 are reserved for various kinds of steady state errors * i.e. anything that comes after the group registration. */ clssomonretMEM = 11, /* memory allocation failure */ clssomonretCSS = 12, /* misc error in CSS layer */ clssomonretFATAL = 13, /* failure in CSS layer that should cause a reboot*/ clssomonretOCR = 14, /* misc error in OCR layer */ clssomonretOSD = 15, /* error in OSD layer used by generic code*/

4，ocssd于oclsomon日志
由于ocssd进程已经暂停了，所有ocssd没有任何日志信息
下面是clsomon日志信息
|
[root@cisser1 ~]# tail -f /oracle/app/oracle/product/10.2.0/crs_1/log/cisser1/cssd/oclsomon/oclsomon.log

5，节点2的日志信息
5.1 ocssd日志信息

这里看以看到主机2在11:45:25的时候开始驱除主机1，但是主机在11:45：23分的时候就开始重启主机了，所以主机重启由于oclsomon进程导致的，而不是节点驱除导致的。
模拟CSSD进程HANG导致RAC节点重启：等您坐沙发呢！
