使用SRVCTL时报错：error while loading shared libraries

1.报错例如以下：

[oracle@rac1 ~]$ srvctl add service -d rac -s test -r "rac1"

/u01/app/oracle/product/dbhome_1/jdk/jre/bin/java: error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory
[oracle@rac1 ~]$ which srvctl   --查看此命令，是在ORACLE_HOME下，正常应该是在CRS_HOME下。
/u01/app/oracle/product/dbhome_1/bin/srvctl

2.解决：改动环境变量，在PATH中将CRS_HOME放前面

[oracle@rac1 ~]$ vi .bash_profile

将$ORA_CRS_HOME/bin:放到$ORACLE_HOME/bin:前面----原来是在后面
PATH=$ORA_CRS_HOME/bin:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH:$HOME/bin:$ASM_HOME/bin

                     
[oracle@rac1 ~]$ which srvctl  
/u01/app/oracle/product/dbhome_1/bin/srvctl

[oracle@rac1 ~]$ source .bash_profile

[oracle@rac1 ~]$ which srvctl    ---此时就是在CRS_HOME下找到的SRVCTL了。
/u01/app/oracle/product/crs/bin/srvctl
[oracle@rac1 ~]$ srvctl add service -d rac -s test -r "rac1"   --能够正常使用。
