Solution Manager 7 Stack Java Not available for Linux RH 5.2?

I need to install the version of Solution Manager 7, chose the Linux platform EL.5.2 64 bits on Oracle 10.2. It is available under the PAM.

I was able to move forward with the installation of Oracle. / RUNINSTALLER, there could not continue because the installation requires Oracle Linux 3 or 4.

Someone knows this kind of restriction?

In just the ABAP stack appears available for RH EL.5.2 X86 64 bits ..
