正确步骤：
1.BUG6880880 ，OPATCH的补丁
2.BUG16902043，11.2.0.3.8补丁
感慨就是要实践啊看着容易的事也一波三折--像OPATCH的版本问题在安装11.2.0.3.8补丁前有提示的，要细心唉。
MOS还是很好用的哈哈。

是OPATCH版本低。
OPatch - Where Can I Find the Latest Version of OPatch? [Video] (文档 ID 224346.1)
文档最后找到：
For Oracle11g Release 2 (11.2.0.x),
select release "11.2.0.0.0" (description "OPatch 11.2") and download
p6880880_112000_platform.zip
As of December 2013 the OPatch release is 11.2.0.3.6
####下载补丁p6880880_112000_platform.zip -----其实这个在PSU的README的最开始就有：
2.1 OPatch Utility
You must use the OPatch utility version 11.2.0.3.0 or later to apply this patch. Oracle recommends that you use the latest released OPatch version for 11.2, which is available for download from My Oracle Support patch 6880880 by selecting the 11.2.0.0.0 release.
For information about OPatch documentation, including any known issues, see My Oracle Support Document 293369.1 OPatch documentation list.
3.安装OPATCH
在ORACLE_HOME下备份OPATCH目录：-bash-3.2$ tar -cvf opatch.tar OPatch/
解压p6880880_112000_platform.zip，将ORACLE_HOME下备份OPATCH目录文件删除，再移动解压目录。
-bash-3.2$ mv OPatch/ /export/home/oracle/u01/app/oracle/product/11.2.0/db_1/
-bash-3.2$ opatch -help
查看是否可用。

4.再次打补丁（数据库关闭、监听关闭、DBCONSOLE关闭） ：
-bash-3.2$ opatch apply日志中有warnings：
-bash-3.2$ tail /export/home/oracle/u01/app/oracle/product/11.2.0/db_1/cfgtoollogs/opatch/opatch2014-05-13_18-29-20PM_1.log
[May 13, 2014 6:52:15 PM] 1) OUI-67215:
OPatch found the word "warning" in the stderr of the make command.
Please look at this stderr. You can re-run this make command.
Stderr output:

从MOS上查询此报错：
Opatch Warning During Patch Apply : "ld: warning: option -YP appears more than once, first setting taken" (文档 ID 1571550.1)可以忽略：

Oracle Solaris on SPARC (64-bit)
Oracle Solaris on x86-64 (64-bit)
Cause
Make warnings caused due to Options for ld command appears more than once.
Solution
These warnings are safely ignorable.
----至此安装完成。
