OPatch succeeded.
2. 查询指定某个补丁号
oracle@www.linuxidc.com:~/product/11g/db/OPatch> ./opatch lsinventory | grep 9352179
Patch 9352179 : applied on Tue Aug 09 15:19:13 CST 2011

补充：如果执行 ./opatch lsinventory 时报错：
oracle@bmsuitedba:/opt/oracle/product/11/OPatch> ./opatch lsinventory

那么极有可能是因为opatch版本过低的原因，需要下载更高版本的opatch使用，如：p6880880_111000_Linux-x86-64.zip，直接解压后就可以使用了。
第二部分：给oracle打补丁
若数据库版本是11.1.0.6.0，现在要将数据库升级为11.1.0.7.3，那么要进行下面的操作：
1. 11.1.0.6.0版本的oracle在官方网站上有zip包可以直接下载得到，安装后的版本就是11.1.0.6.0；
2. 11.1.0.7.0版本是在11.1.0.6.0的基础之上，通过打一大补丁才可以得到，这个大补丁需要有oracle的账号方可以下载，当然网上可能有网友共享出来的。比如为：p6890831_111070_Linux-x86-64.zip，解压后得到Disk1目录，然后进行如下操作：
oracle@bmsuitedba:~/setup> cd Disk1/
oracle@bmsuitedba:~/setup/Disk1> ls
11107_buglist.htm install patch_note.htm response runInstaller stage
oracle@bmsuitedba:~/setup/Disk1> ./runInstaller --这一步需要图形界面
3. 11.1.0.7.3版本是在11.1.0.7.0的基础之上，通过打小补丁才可以得到。比如补丁号为：9352179，补丁包为：p9352179_111070_Linux-x86-64db.zip
解压后得到9352179目录：
oracle@bmsuitedba:~/setup> cd 9352179/
oracle@bmsuitedba:~/setup/9352179> /opt/oracle/product/11/OPatch/opatch apply -- 注意，执行这一步，必须要进入到刚才解压出来的补丁包的目录中，然后通过使用完整的opatch路径来执行opatch，否则会报错
附：如果使用oracle安装时的opatch版本过低，就会在执行opatch打版本过程中出错，此时需要另外下载一个高版本的opatch包，比如在上面的操作中就会报错，需要使用这个版本的opatch包：p6880880_111000_Linux-x86-64.zip，直接解压就可以使用了。
