Recently I got a hardware upgrade so I could finally switch to a 64-bit environment. To fully use that machine I wanted to install TIBCO in 64-bit mode. After starting the installation I got this message:

TIBINS202527: Error: ERROR: You are running a 64-bit product installer on a 32-bit system.

This is not supported.

The Problem was I was running a 64-bit OS with a 64-bit Kernel:

So I tried to find the problem. First I needed some more output what the installer is actually doing. So I used the logging option to get all the debug output.

So when you look closer to this log you can see that the command which is running the installer looks like this:

Executing launch script command: “/tmp/isjI8lFYy/bin/java” -cp “”:”TRA.5.6.0-suite_linux24gl23_x86.jar”:”TRA.5.6.0-simple_linux24gl23_x86.jar”:”tibrv.8.1.1-simple_linux24gl23_x86.jar”:”jre.1.5.0-simple_linux24gl23_x86_64.jar”:”Designer.5.6.0-simple_linux24gl23_x86_64.jar”:”tpcl.5.6.0-simple_linux24gl23_x86.jar”:”hawk.4.8.1-simple_linux24gl23_x86_64.jar”:”/tmp/isjA5jEsB/TRA.5.6.0-suite_linux24gl23_x86.jar”:”” -Dtemp.dir=”/tmp” -Dis.jvm.home=”/tmp/isjI8lFYy” -Dis.jvm.temp=”1″ -Dis.media.home=”/tmp/isjA5jEsB/TRA.5.6.0-suite_linux24gl23_x86.jar” -Dis.launcher.file=”/home/jens/tmp/TIB_tra-suite_5.6.0_linux24gl23_x86_64/./TRA.5.6.0-suite_linux24gl23_x86.bin” -Dis.jvm.file=”/tmp/isjI8lFYy/jvm” -Dis.external.home=”/home/jens/tmp/TIB_tra-suite_5.6.0_linux24gl23_x86_64/.” -Xms20m -Xmx128m run -home TRA.5.6.0-suite_linux24gl23_x86.jar “-console”

Now that I had the command which is starting the installer I began to trace what this process is doing. To do a strace properly you just have to prepend ‘strace’ and than redirect the error output to a file (cause it is quiet a lot). So after doing this I found something interesting in the log.

[pid 32651] execve(“/bin/uname”, [0xffffffffdf47dc88, “-p”], [/* 1757 vars */]) = 0

As you can see it runs the command ‘uname -p’. This command returns ‘unknown’ for a default debian system. You also have this problem if you are running a self compiled kernel from kernel.org. As for the TIBCO supported systems (SUSE ans redhat) they return something different. After trying the same command on a openSUSE I found that ‘x86_64’ should be the correct string. After I bit of trial and error I found out that the result of this command is written to a file name ‘kernelbits_jens.txt’ in the temp directory.

So here the simple solution to the problem.

You just need to create the arch file manually and make it read-only so the installer can’t overwrite it. Here the command:

Now the installer worked absolutely fine for me.

I already notified the TIBCO support about the problem. As for now there will be no fix. But I hope they will correct this behavior for future installer.
