I still don't know what you mean.  If you tell the installer to
"create symlinks to standard directories", you don't have to do
anything else.  If you don't, you have to add the bin directory to
PATH.  But if there is another TeX distribution on your system
already, you should make sure that the version you want to use comes
first in PATH, i.e.

  PATH=/path/to/current/texlive/bin:$PATH
  export PATH

If the version you want to use doesn't precede other versions in PATH,
I can guarantee you that you'll have a lot of fun.

Another problem can occur if you already have a complete TeX Live
system installed on your machine and install a newer version but don't
select "scheme full" at install time.  It's obviously clear what
happens.

Nevertheless, since you said

  "If symlinks are not there, tlmgr exectues executables from system"

I'm convinced that PATH is not set properly.
