+ exit 67

Then, the truss command shown this :

3605258: 7602997: execve("/usr/bin/echo", 0x201264E0, 0x201264EC) Err#8 ENOEXEC

Looking at OS doc it means :

       ENOEXEC
              An executable is not in a recognized format, is for the wrong architecture, or has some other format error that means it cannot be executed.


So focussed attention towards echo file.


>which echo
/usr/bin/echo
 

> ls -eal /usr/bin/echo
-r-xr-xr-x-    1 bin      bin               0 May 25 2016  /usr/bin/echo

 

0 byte file!
 

After getting assistance from sys admin ( where the DB2 DBA replaced the echo file from other good system) the db2 installation worked fine.
Apparently the *good* copy of echo was overwritten by some other script/program by mistake from client side.
