rubywmq (1.1.1)

pwd
/var/mqm

-bash-4.1$ ruby put1_a.rb
put1_a.rb:23:in connect': WMQ::QueueManager#connect(). Failed to load MQ Library:libmqm_r.so, rc=libmqm_r.so: cannot open shared object file: No such file or directory (WMQ::WMQException) from put1_a.rb:23:in

The suplied sample program:

cat put1_a.rb

Sample : put1() : Put a single message to a queue

require ‘rubygems’
require ‘wmq/wmq’

WMQ::QueueManager.connect(:q_mgr_name=>‘T400.P.QM’) do |qmgr|
qmgr.put(:q_name=>‘T400.P.LQ’, :data => ‘Hello World’)
end

Any help will be appreciated.

Thank you
