Preparing to launch Oracle Universal Installer from /tmp/OraInstall2015-03-24_12-33-40AM. Please wait ...The Java RunTime Environment was not found at /tmp/OraInstall2015-03-24_12-33-40AM/jdk/jre/bin/java. Hence, the Oracle Universal Installer cannot be run.
Please visit http://www.javasoft.com and install JRE version 1.3.1 or higher and try again.
: No such file or directory

Analysis:

Java 1.6 update 65 is already installed and JAVA_HOME environment variable is set as well as PATH variable has $JAVA_HOME/bin entry. Verified the settings with which java and java -version commands


Solution:

oraparam.ini file under the software staged directory path /software/FR11121/Disk1/install/linux64 had an entry JRE_SCRATCH_LOC

It was set to 
JRE_SCRATCH_LOC=jdk/jre

Commented out above line using VI editor and saved the file

vi oraparam.ini

#JRE_SCRATCH_LOC=jdk/jre

Reinvoked runInstaller.

This time runInstaller prompted for java path and I gave the already installed path and installer took it


bash-4.1$ ./runInstaller
