OPatch 报错：OPatch needs to modify files which are being used by some processes.

在执行下面的语句的时候，opatch报了一个错误，从网上查了下解决办法：

[oratest@lyg 7319922]$ opatch rollback -id 7319922

我从网上搜了下面一个人，跟我遇到了相似的错误：

http://deryaoktay.wordpress.com/2012/02/08/prerequisite-check-checkactivefilesandexecutables-failed-error-while-issueing-opatch-apply/

While applying interim patch, I got Prerequisite check “CheckActiveFilesAndExecutables” failed error and resolved the issue with the help of fuser.

————从上面看，跟我遇到的问题基本类似，接着看他的解决方法：

Cause：

Something is using oracle library.

Solution：

I had solved the issue first looking at the log file and saw that the inuse control made by fuser, this is also a clue for me to find who is using the library file.

oracle@mydb1>/sbin/fuser /u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1
 /u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1: 12195m
 oracle@mydb1>

oracle@mydb1>ps -ef |grep 12195
 oracle   12195 11944  0 Jan19 pts/7    00:00:00 adrci
 oracle   22813  3717  0 21:18 pts/13   00:00:00 grep 12195
 oracle@mydb1>kill -9 12195

After than I had successfully applied the patch

根据他这种做法，我也试着做了下：

[oratest@lyg 7319922]$ /sbin/fuser /u01/prod/db/tech_st/11.1.0/bin/oracle
/u01/prod/db/tech_st/11.1.0/bin/oracle: 10758e 10760e 10764e 10766e 10768e 10770e 10772e 10774e 10776e 10778e 10780e 10782e 10784e 10786e 10797e 10801e 10815e 10821e 10825e 10916e 12186e

我发现都是oracle自己的后台进程，难道要把oracle数据库先关了，再执行这一步？我关了数据库，在执行试试：

我擦，果然关了数据库在执行就好了。。。看来是我经验不足啊。。以后多留意。。
