What version of Terracotta Server you are currently using;
Paste the configuration you are using;
Providing JDK and OS versions maybe useful as well.

I am trying to run multiple nodes of Terracotta for BigMemoryMax using a trial version. I was able to run my test with EHcache and one Terracotta server/Node. How can I add more nodes to the cluster. Any links to an example will be helpful.

I have tried to change the tc-config.xml by adding multiple server node but some how the TMC console is recognizing only one node in the cluster.

Could you post the config you're using so we can review it?

Generally speaking, you need a tc-config.xml file that configures each server you will have be part of the TSA (cluster), and then you need to start each server with that same config.

Please find below the tc-config.xml containing 4 servers. Now when I run the four commands below one by one, I get one ACTIVE node and 3 Mirrors.

How can I get multiple Active nodes? Also please direct me to some good multiple distributed node example.

Hello,

You need to define 2 stripes (using the mirror group tag), and in each stripe, 2 nodes

try updating your tc-config.xml with this :

<tc:tc-config xmlns:tc="http://www.terracotta.org/config">

<tc-properties>

</tc-properties>

<mirror-group group-name="StripeOne">

<data>tsa-region-3/data</data>

<logs>tsa-region-3/logs</logs>

<index>tsa-region-3/index</index>

<tsa-port>9710</tsa-port>

<jmx-port>9720</jmx-port>

<tsa-group-port>9730</tsa-group-port>

</offheap>

</server>

<data>tsa-region-4/data</data>

<logs>tsa-region-4/logs</logs>

<index>tsa-region-4/index</index>

<tsa-port>9810</tsa-port>

<jmx-port>9820</jmx-port>

<tsa-group-port>9830</tsa-group-port>

</offheap>

</server>

</mirror-group>

<mirror-group group-name="StripeTWO">

<data>tsa-region-2/data</data>

<logs>tsa-region-2/logs</logs>

<index>tsa-region-2/index</index>

<tsa-port>9610</tsa-port>

<jmx-port>9620</jmx-port>

<tsa-group-port>9630</tsa-group-port>

</offheap>

</server>

<data>tsa-region-1/data</data>

<logs>tsa-region-1/logs</logs>

<index>tsa-region-1/index</index>

<tsa-port>9510</tsa-port>

<jmx-port>9520</jmx-port>

<tsa-group-port>9530</tsa-group-port>

</offheap>

</server>

</mirror-group>

</servers>

<logs>client-region-1</logs>

</clients>

</tc:tc-config>

Thanks Anthony, could u also suggest the command to start the two active nodes, specifically do I need to pass on the server name with -n options twice for starting two active nodes

Run the exact same commands as you did before, but this time since you applied Anthony configuration changes, you'll end up with 2 actives / 2 mirrors.

And you probably should delete the various data folders (tsa-region-3/data, etc) to start all the nodes clean with this new topology.
