oracle版本为11.2.0.3，系统版本为Centos Linux 6.6 X86_64,安装完成grid软件后，一切正常，没有报错，但是使用sqlplus / as sysasm后提示连接到空闲进程
[[email protected] dbs]$ sqlplus / as sysasm; SQL*Plus: Release 11.2.0.3.0 Production on Mon Apr 25 15:08:06 2016 Copyright (c) 1982, 2011, Oracle. All rights reserved. Connected to an idle instance. SQL> startup mount; ORA-15149: another ASM instance found running on the host
检查css状态

发现ora.diskmon为offline状态，查阅资料后发现从11.2.0.3版本开始默认diskmon在非exadata上是禁用状态
11.2.0.3 Grid Infrastructure diskmon Will be Offline by Default in Non-Exadata Environment [ID 1346881.1]
百般折腾看是否有办法启用ora.diskmon,设置auto_start为1也没有效果，检查asm进程

监听状态正常
检查参数文件init+asm.ora也没发现问题
[[email protected] dbs]$ cat init+asm.ora *.asm_power_limit=1 *.instance_type=‘asm‘ *.large_pool_size=12M *.remote_login_passwordfile=‘EXCLUSIVE‘ *.asm_diskstring=‘/dev/asm-disk*‘
最后检查.bash_profile文件配置
[[email protected] dbs]$ cat ~/.bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs ORACLE_BASE=/u01/app; export ORACLE_BASE ORACLE_HOME=/u01/app/grid; export ORACLE_HOME ORACLE_SID=+asm; export ORACLE_SID export LD_LIBRARY_PATH=$ORACLE_HOME/lib PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin export PATH
ORACLE_SID为小写的+asm,而实际进程中的为大写+ASM，oracle区分大小写，改为大写后再连接后就正常了

连接后OK
