OPatch failed with error code 73  
仔細查看報錯提示“Check Active Files And Executables”可能是有些執行程序用到了  
/opt/oracle/product/db_1/lib/目錄下的庫文件libclntsh.so.11.1  
2.使用fuser查看  
[oracle@ora_11g oinstall]$ /sbin/fuser   /opt/oracle/product/db_1/lib/libclntsh.so.11.1  
/opt/oracle/product/db_1/lib/libclntsh.so.11.1: 12831m  
3.查看12831號進程，12831號進程爲sqlplus 程序，應該就是sqlplus正在使用libclntsh.so.11.1庫文件  
[oracle@ora_11g oinstall]$ ps -ef | grep 12831  
oracle   12831  6986  0 21:44 pts/3    00:00:00 sqlplus   as sysdba  
oracle   12832 12831  0 21:44 ?        00:00:00 oracletest01 (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))  
oracle   12993  9126  0 21:47 pts/1    00:00:00 grep 12831  
[oracle@ora_11g oinstall]$   
4.殺掉12831進程，查看結果  
[oracle@ora_11g oinstall]$ kill -9 12831   
[oracle@ora_11g oinstall]$ ps -ef | grep 12831  
oracle   13013  9126  0 21:55 pts/1    00:00:00 grep 12831  
5.重新執行opatch 順利執行完成
