IS Cluster node is getting dropped from the cluster

,

Hi Folks,

Good day to you.

I am trying to configure wM 9.9 IS cluster using single Terracotta server.

After restarting both the nodes cluster is getting enabled on both the nodes and both the nodes are appearing in the cluster hosts. After some time ( few seconds ) one of the node is getting disappeared from the cluster and only one node remained in it.

But when I check the Terracotta Management Console , it is showing the cluster status as active and both the nodes are appearing in the cluster.

Steps Followed to configure IS Cluster:

Step 1: Enabled cluster on both nodes,

Step 2: Configured tc-config.xml as below

<?xml version="1.0" encoding="UTF-8" ?>

<tc:tc-config xmlns:tc=“http://www.terracotta.org/config”
xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=“http://www.terracotta.org/schema/terracotta-9.xsd”>



/opt/softwareag99/Terracotta/data

9510
9520
9530
9540








true
false
3600


120

</tc:tc-config>

Step 3 : Started Terracotta server using tsa-service wrapper.

Step 4 : Restarted IS nodes one by one.

FYI : I have done the same configuration on other environments where IS clustering is working fine.

Please share your comments/inputs to resolve this issue.

Regards,
Venkat.

I am also facing the same kind of problem. Checked clustering in the IS admin page. Terracotta is getting reflected both IS. However one of the TC is down in DR server. Not sure how it is getting displayed in IS!!!

I have resolved the issue.

Seems to be some of the configuration files got corrupted as we have changed /etc/hosts files many times and IP & hostname of the server for couple of times.

Re-installed IS and configured IS clustering. Now it is working fine without any issues.
