Looks like an issue with your Java version. Check certification matrix to confirm you are using the right Java version.

[Deleted User]

Your java is tool old. If you look at the certification matrix for the OS you're installing on you'll see that for most 'nix systems you'll need 1.8.0_101 at least:

Hi Sherry ,

I have already checked the certification matrix before doing the upgrade.Its not because of the incorrect java version.It looks like jre runtime is not upgraded to Java 8(supported version) but i have also checked .profile and etc/profile, both are directed to supported version.

Please suggest!!

Hi,

Just to confirm is that the only JDK installed in your machine ? What is the output of "java -version" ?

saketsrv

HI Sherry,

[obiee@ubiuat:/home/oraclebi]$java -version

Java(TM) SE Runtime Environment (build 1.8.0.08-hp-ux-b1)

Java HotSpot(TM) Server VM (build 25.08-b1, mixed mode)

[obiee@ubiuat:/home/oraclebi]$echo $JAVA_HOME

Sherry George

ok, could you also confirm if you checked the java -version before launching the FMW installer? Also please post the command you used to start the FMW installer.

saketsrv

Yes .I checked the version before launching the FMW installer.

Command to launch FMW:

/opt/java8/bin/java -d64 -jar fmw_12.2.1.2.0_infrastructure.jar

Sherry George

At this point I'll suggest you to re-install using the latest jdk version.

saketsrv

Hi Sherry,

So you mean re-installing application or jdk?

Because i have also tried re-installing application couple of times but that didn work either.

Any suggestion on how to make compile jdk and jre runtime to use same version during installation in case of mismatch?
