title: How to change the SDR channel definition of IBM MQ
body: <p>I need to change the <code>CONNAME('xx.xx.xxx.xx(1414)</code> to <code>CONNAME('yy.yy.yyy.yy(1414)</code> for IBM MQ. I searched through the internet I did not found any command. My object definition code is given below.</p>
  
  <pre><code>DEFINE CHANNEL(CHANNELNAME) +
         CHLTYPE(SDR) +
         TRPTYPE(TCP) +
         MAXMSGL(30000000) +
         DESCR('Channel to REPLY TO sender') +
         XMITQ('Sender.XMITQ') +
         CONNAME('xx.xx.xxx.xx(1414)') +
         BATCHSZ(50) +
         DISCINT(6000) +
         SHORTRTY(10) +
         SHORTTMR(60) +
         LONGRTY(999999999) +
         KAINT(AUTO)   +
         LONGTMR(1200) +
         SEQWRAP(999999999) +
         CONVERT(YES) +
         MCATYPE(PROCESS) +
         HBINT(300) +
         BATCHINT(0) +
         NPMSPEED(FAST)    
  </code></pre>
  
  <p>Can I use the <code>ALTER</code> command? if I delete the channel and redefine it will it cause any problem to existing channels and queues?</p>
