RAC好不容易装好，在练习管理时发现srvctl命令不能用（我的环境：RedHat5.4+clusterware10.2+oracle10.2）

[oracle@node1 bin]$ srvctl
/u01/oracle/10.2.0/db_1/jdk/jre/bin/java: error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory

提示说是bin路径不正确

[oracle@node1 bin]$ which srvctl
/u01/oracle/10.2.0/db_1/bin/srvctl
[oracle@node1 bin]$ echo $CRS_HOME
/u01/oracle/product/10.2.0/crs_1

发现srvctl的路径果然不正确，跟我自己设置的CRS_HOME不一致，就考虑到是环境变量的问题：

[oracle@node1 bin]$ cat ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export ORACLE_SID=mydb1
export ORACLE_BASE=/u01/oracle
export CRS_HOME=$ORACLE_BASE/product/10.2.0/crs_1
export ORACLE_HOME=$ORACLE_BASE/10.2.0/db_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$CRS_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
export EDITOR=vi
export PATH

环境变量配置无误，并且如网上其他高手所说，CRS_HOME已经配置在ORACLE_HOME前面了，为啥还会出错呢

又在网上找到资料，发现要想修改vipca一样修改srvctl文件：

[oracle@node2 ~]$ cd $CRS_HOME/bin
[oracle@node2 bin]$ vi srvctl
修改以下两行：
#Remove this workaround when the bug 3937317 is fixed
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
添加
unset LD_ASSUME_KERNEL

或者直接将这两行注释
#LD_ASSUME_KERNEL=2.4.19
#export LD_ASSUME_KERNEL

这下总可以了吧：
[oracle@node1 bin]$ srvctl
/u01/oracle/10.2.0/db_1/jdk/jre/bin/java: cannot open shared object file: No such file or directory
哦，麦噶登，还是不行

再次回来查看该命令的路径

[oracle@node1 bin]$ which srvctl
/u01/oracle/10.2.0/db_1/bin/srvctl

既然命令路径不正确，修改CRS_HOME下的命令文件肯定是没用的，就去/u01/oracle/10.2.0/db_1/bin/瞅了瞅
果然有srvctl文件，赶紧的修改这个命令文件：

[oracle@node1 bin]$ cd /u01/oracle/10.2.0/db_1/bin/
[oracle@node1 bin]$ vi srvctl
老方法
#Remove this workaround when the bug 3937317 is fixed
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
添加
unset LD_ASSUME_KERNEL

或者直接将这两行注释
#LD_ASSUME_KERNEL=2.4.19
#export LD_ASSUME_KERNEL

保存退出，再试试：
[oracle@node1 bin]$ srvctl
Usage: srvctl
