PeopleTools 8.53 Linux Version PIA: JDK 7 Issues

Question

Folks,
Hello. I am installing PeopleTools 8.53 (Linux Version) with WebLogic11gR1 Generic and Coherence (file name V29856-01) that requires JDK 7 Linux x86-64 (file name V35017-01). All files are downloaded from http://www.edelivery.oracle.com.
Before install WebLogic 11gR1, we need to install JDK 7. After extract v35017-01.zip in Linux, it turns into the file jdk-7u9-linux-x64.rpm.
When install the file, I get the message as below:
[root@localhost Java7_JDK_Linux_64bit]# rpm -ivh jdk-7u9-linux-x64.rpm

[root@localhost Java7_JDK_Linux_64bit]#
Some folks told me the above message is a warning and can be ignored. However, I have deleted the default installation directory /usr/java and install it again and get the message below:
[root@localhost Java7_JDK_Linux_64bit]# ls
jdk-7u9-linux-x64.rpm V35017-01.zip
[root@localhost Java7_JDK_Linux_64bit]# rpm -ivh jdk-7u9-linux-x64.rpm

[root@localhost Java7_JDK_Linux_64bit]#
[root@localhost Java7_JDK_Linux_64bit]# rpm -ivh --prefix=/JDK7 jdk-7u9-linux-x64.rpm
Preparing... ########################################### [100%]
package jdk-1.7.0_09-fcs is already installed
[root@localhost Java7_JDK_Linux_64bit]#
The default installation directory is /usr/java, but the package jdk-1.7.0_09-fcs is not in /usr/java. I search the entire file system, but the packagejdk-1.7.0_09-fcs is not in any other directories.
My questions are:
First, the package jdk-1.7.0_09-fcs is not in any directory. Why the message says "package jdk-1.7.0_09-fcs is already installed" ?
Second, I try to install it into another location /JDK7 and get the same message as above. What's wrong ?
Third, do I need to remove entire directory /usr and then reinstall it ?
Thanks.

Don't delete /usr or you'll be reinstalling your OS.
since you installed with rpm, you should have removed with rpm. deleting the files installed by rpm does not remove the package from the rpm database.
try doing
rpm -Uvh --force jdk-7u9-linux-x64.rpmto reinstall over top the existing package
man rpmgives you all the documentation and there is countless pieces of information available online. It sounds like you should read up on Linux Administration basics. Administering/Installing PeopleSoft requires some skill in operating systems, without them you will run into potential problems all over the place.
