我手动启动遇到了一个问题：
停止在这里
[grid@m1 ~]$ crs_start ora.mes.db
Attempting to start `ora.mes.db` on member `m1`
Attempting to start `ora.FRA.dg` on member `m2`
Attempting to start `ora.DATA.dg` on member `m3`
Start of `ora.FRA.dg` on member `m2` succeeded.
Attempting to start `ora.mes.db` on member `m2`
Start of `ora.DATA.dg` on member `m3` succeeded.
Attempting to start `ora.mes.db` on member `m3`
CRS-5017: The resource action "ora.mes.db start" encountered the following error:
ORA-03113: end-of-file on communication channel

. For details refer to "(:CLSN00107:)" in "/u01/app/grid/11.2.0/log/m3/agent/crsd/oraagent_oracle/oraagent_oracle.log".
Start of `ora.mes.db` on member `m3` failed.
Attempting to stop `ora.mes.db` on member `m3`
Stop of `ora.mes.db` on member `m3` succeeded.
CRS-2632: There are no more servers to try to place resource 'ora.mes.db' on that would satisfy its placement policy
m3 的数据库不能通过命令 crs_start ora.mes.db 启动。
m1 m2 m3 三台机器都出现了这个情况
m3 的数据库不能通过命令 crs_start ora.mes.db 启动。
数据库RAC环境安装好了之后，我没有检查过但是过了一段时间之后
1、3台数据库全部停了
2、3台数据库 全部出现 ORA-01155: the database is being opened, closed, mounted or dismounted
3、我怀疑是归档的问题。 查看alter.log 出现：
最多的就是 文件不归档：
解决：
asmcmd
ls
cd data
mkdir arch
exit
1、关闭所有节点数据库实例
c:>srvctl stop database -d RACDB
2、修改服务器配置参数
sql>startup mount
sql>alter system set cluster_database=false scope=spfile;
sql>shutdown immediate
3、调整归档日志路径
sql>startup mount
sql>alter system set log_archive_dest_1='LOCATION=+RAC_DISK' scope=spfile sid='RACDB1';
sql>alter system set log_archive_dest_1='LOCATION=+RAC_DISK' scope=spfile sid='RACDB2';
调整归档日志文件命名方式
sql>alter system set log_archive_format ='arch1_%s_%R_%T.arc' scope=spfile sid='RACDB1';
sql>alter system set log_archive_format ='arch2_%s_%R_%T.arc' scope=spfile sid='RACDB2';
4、开启归档日志
sql>alter database archivelog
sql>alter database open
5、恢复服务器配置参数
sql>alter system set cluster_database=true scope=spfile;
sql>shutdown immediate;
6、打开所有节点数据库实例
c:>srvctl start database -d RACDB
7、检查归档日志是否已启用
c:>sqlplus / as sysdba;
sql>archive log list;
说明：
其中2~5、7是在单节点下操作的
