"RAC的第一个节点不停重启的问题"

是 Oracle Instance 实例重启还是节点 Node 重启？

是实例重启，ora.rac.rac1.inst启动后，又挂掉，重复几次现在处于down状态。
[root@rac1 bin]# ./crs_stat -t

把 ora.rac.rac1.inst 这个实例的告警日志 ALERT.LOG 上传，而不是 CRS 的 ALERT.LOG

可以通过 background_core_dump 参数找到alert.log 所在目录

SQL> show parameter background
NAME                               TYPE       VALUE
------------------------------------ ----------- ------------------------------
background_core_dump                string    partial
background_dump_dest                string    /home/opt/app/admin/rac/bdump

alert_rac1.log应该是在 /home/opt/app/admin/rac/bdump里吧，如果是的话，附件里已上传。

另一个问题：
首先我的是测试用的rac，workstation里的，今天打开后，发现rac1部分服务没起来，而且rac2系统打开后，十几秒以后就自动重启。
在网上找了原因，然后查看了rac2上 /var/log/messages 里的记录，写着Mar 14 13:52:32 rac2 logger: Oracle CSSD failure.  Rebooting for cluster integrity；
然后又看到 rac2上ocssd.log里记录很多条这样的记录：
[ CSSD]2012-03-13 21:40:25.102 [161037200] >TRACE: Authentication OSD error, op: scls_auth_response_prepare
loc: mkdir info: failed to make dir /home/opt/app/product/10.2.0/crs_1/css/auth/A2172926, No space left on devicedep: 28
，2012-03-13 21:40:25正好是昨天晚上关机时间。
然后在rac2上查看了下磁盘空间，确实在rac2的安装目录下没了空间，删除trc文件后，然后重启了服务，刚才都好了。
现在我隔几分钟看下rac2的空间，发现空间消耗速度很快，基本上几分钟消耗100M的空间，请问这个正常吗？

做了很多cdump，Oracle检测到DB有问题，对每个进程进行转储，这会耗费很多空间
RAC经常碰到的问题
看一下trc文件，为什么要做这些数据块的恢复

存在大量的 ORA-600 [4553] 错误：

Errors in file /home/opt/app/admin/rac/bdump/rac1_j000_27869.trc:
ORA-00600: internal error code, arguments: [4553], [2], [0], [], [], [], [], []
Wed Mar 14 13:57:32 2012
Trace dumping is performing id=[cdmp_20120314135732]

ORA-600 [4553] Usually this is caused by OS or hardware errors and all previously reported issues to development have been closed as not a bug. e.g.:

[45XX] ktb.c Kernel Transaction Block code.

一般是由于Lost Write引起的 Block Corruption。

该ORA-600 错误会引起大量的core dump写出占用磁盘空间，究其原因可能是Vmware异常重启引起的。

真正引起 instance reboot 实例重启的原因是 LMS Global Cache Service process遇到 ORA-600 [4519]错误：

Errors in file /home/opt/app/admin/rac/bdump/rac1_lms0_22118.trc:
ORA-00600: internal error code, arguments: [4519], [2], [12613912], [0], [], [], [], []

Trace dumping is performing id=[cdmp_20120313195157]
Tue Mar 13 19:52:06 2012
Errors in file /home/opt/app/admin/rac/bdump/rac1_lms0_22118.trc:
ORA-00600: internal error code, arguments: [4519], [2], [12613912], [0], [], [], [], []

LMS0: terminating instance due to error 484
Tue Mar 13 19:52:06 2012
System state dump is made for local instance
System State dumped to trace file /home/opt/app/admin/rac/bdump/rac1_diag_22110.trc

LMS 遇到 ORA-600 [4519] 从而crash instance 可能由于Hdr: 6329991 10.2.0.3 Abstract: LMS REPORTS ORA-600 [4519] THEN INSTANCE TERMINATED 引起。

同时这个 ORA-600 [4519] 会触发LMS进程让diag 写出一个systemstate dump的转储文件，一般来说这个dump文件也很大，一次至少几十兆。

建议你至少升级到 10.2.0.5 ， 10.2.0.1 的RAC 是很不稳定的。
