解决办法：
Oracle工程师建议安装Oracle补丁p3949307_9206_SOLARIS64，经过测试，安装步骤如下： （注意，首先shutdown数据库）
1，解压补丁文件
unzip p3949307_9206_SOLARIS64.zip
解开后的目录是：4060756
2，修改oraclehomeproperties.xml文件，该文件在$ORACLE_HOME/inventory/ContentsXML目录下。
cp oraclehomeproperties.xml oraclehomeproperties.xmlb.bak
vi oraclehomeproperties.xml
更改数字453 －>23,存盘退出
3，修改PATH路径为
PATH=$ORACLE_HOME/bin:/usr/ccs/bin:${PATH}
4，执行opatch apply命令
cd 4060756
$ORACLE_HOME/OPatch/opatch apply
5，安装成功后会出现如下结果
