<div>Hi Nick.</div>
<div id="AppleMailSignature"><br>
</div>
<div id="AppleMailSignature">Let me ask you a few things;</div>
<div id="AppleMailSignature"><br>
</div>
<div id="AppleMailSignature">- How is the cluster laid out (how many nodes in the cluster and what nodes are in which DC)?</div>
<div id="AppleMailSignature"><br>
</div>
<div id="AppleMailSignature">- Are you using DNS and if so, where is the DNS server located and do you have redundant DNS in both DCs?</div>
<div id="AppleMailSignature"><br>
</div>
<div id="AppleMailSignature">- Where is your DRS server in relation to the cluster publisher (same DC or no)?<br>
<br>
Thanks,
<div><br>
</div>
<div>Ryan</div>

<div dir="ltr">I'm wondering how many others have had as many issues with db replication? It seems that any time we lose a connection to our 2nd data center (even a 2 minute MPLS planned maintenance outage causes the issue), our database synchronization has
errors. After a WAN blip, within an hour or so, I get a message from RTMT about a subscriber being in "blocked" state:
<div><br>
</div>
<div>
<p class="">%[AppID=Cisco Database Layer Monitor][ClusterID=ProdVoiceCluster][NodeID=XXXXXXX1]: A change notification client is busy (blocked). If the change notification client continues to be blocked for 10 minutes, the system automatically clears the block
and change notification should resume successfully."</p>
<p class=""><br>
</p>
<p class="">After that, if I run utils dbreplication status, it will have errors... so then I run the "repair all" option and it fixes it. Then I'm good for a few weeks until something else happens that starts the whole cycle over.</p>
<p class="">Something else that happens after a WAN blip is that DRS begins to fail, so we have to restart the master DRS and the subsequent DRS services on the subs. Am I doing something wrong? Is this normal?</p>
<p class="">I'm on CUCM 10.0.1.12900-2. </p>
