I download "SCM Tools - Linux for System Z" for zLinux from "plain .zip" location in "" link.

After that I extracted below the location and I verified status using lscm, Now I got Floating point exception I tried with "fec -v" then I received "Floating point exception" error.

/opt/IBM/TeamConcert/scmtools/eclipse # ./lscm status
./lscm: line 28: 15129 Floating point exception"${PRGPATH}/fec" "$@"

Here, which one I missed and why it's not showing version number..?

Not sure why it is showing a floating point exception. Can you try setting an environment variable LSCM_USE_JAVA_FEC to any value say 1 and run the command again? If you still see some errors run 'scm daemon stop -a' and then re-run the lscm command.

 Hi Shashikant

Thanks for reply my post.

I tried with your suggestion but it's not working and even there is no 'scm daemon' running in my machine.

Here's my problem when I run ./fec -v in zLinux server I received "Floating point exception" but in Ubtuntu server it's works well.

For additional informaiton, We used below the version zLinux and Java server.  
SUSE Linux Enterprise Server 10 (s390x)
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2)
Classic VM (build 1.4.2, J2RE 1.4.2 IBM build cxz64142ifx-20060209 (SR4-1) (JIT enabled: jitc))

You should not be using fec binary. Always use lscm. I hope you tried the above suggestion with lscm and not fec.

Also, Java version must be 1.6.

Hi Shashikant

I tried but it's not working.

Still it's shows "./lscm: line 28: 15129 Floating point exception"${PRGPATH}/fec" "$@" " so I just try "fec -v" if it's works.

So in my scenario what was the problem where I missed.? do you have any idea..?

I have a suspicion it's your Java version.  I'm pretty sure Java 1.4.2 is not supported.  The system requirements documentation indicates that Java 1.6 is required for CLM 5.0:
