Terracotta Discussion Forums

I have successfully installed terracotta web-session, Tomcat7 connected teracotta session. Now I want to install ehcache, but it does not work?

Step1:
I copy 4 file in folder ${TERRACOTTA_HOME}/ehcache/lib.
1. ehcache-terracotta-ee-<version>.jar <version>
2. ehcache-core-ee-<ehcache-version>.jar
3. slf4j-api-<slf4j-version>.jar
4. slf4j-jdk14-<slf4j-version>.jar
and copy ${TERRACOTTA_HOME}/common/terracotta-toolkit-<API-version>-runtime-ee-<version>.jar to $TOMCAT/lib

Step2:
I create file ehcache.xml, copy to WEB-INF/classes

Code:

<?xml version="1.0" encoding="UTF-8"?>
 <ehcache name="myCache"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="ehcache.xsd">
   <defaultCache
      maxElementsInMemory="0"
      eternal="false"
      timeToIdleSeconds="1200"
      timeToLiveSeconds="1200">
          <terracotta />
   </defaultCache>
   <terracottaConfig url="192.168.2.204:9510" />
 </ehcache>

Step3: Start terracotta.
Code:

./start-tc-server.sh -f /home/administrator/Terracotta/terracotta-ee-3.6.2/tc-config.xml

tc.config.xml
Code:

<?xml version="1.0" encoding="UTF-8"?>
 <tc:tc-config xmlns:tc="http://www.terracotta.org/config"

I did wrong steps?, please help me.
Sorry for bad english

I follow the instructions below:
http://terracotta.org/documentation/enterprise-ehcache/installation-guide

I don't think you following the steps on that page. Your tc-config.xml has DSO items in it; do not use a TIM and do not instrument classes. Follow the instructions exactly as shown.

Yes, file tc-config.xml i following the http://artur.ejsmont.org/blog/content/how-to-setup-terracotta-session-clustering-and-replication-for-apache-tomcat-6 to install the web-session.
How can i edit file tc-config.xml to install ehcache ?

I try edit file tc-config.xml, but also can't install ahcache :(

Code:

<?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"

    </modules>
  </clients>
  </tc:tc-config>

Please help me :(

I can't speak to the accuracy of that blog you mention -- it's a bit outdated and uses DSO. You should try the instructions in http://terracotta.org/documentation/enterprise-ehcache/installation-guide with a clean start. That should work.

Thank ilevy, I will try.

I try install follow intrustructions, but ehcache not connect to terracotta serrver ?
I have 2 server. Server1 install Terracotta (ip: 192.168.2.202). Server2 install Liferay.

I use Liferay Protal, have two folder lib
$TOMCAT_HOME/lib and $TOMCAT_HOME/webapps/ROOT/WEB_INF/lib
Folder class: $TOMCAT_HOME/webbapp/ROOT/WEB_INF/classes
Step1: I copy
ehcache-core-ee-2.5.2.jar
ehcache-terracotta-ee-2.5.2.jar
slf4j-api-1.6.1.jar
slf4j-jdk14-1.6.1.jar
terracotta-toolkit-1.5-runtime-ee-4.2.0.jar
to $TOMCAT_HOME/webbapp/ROOT/WEB_INF/lib
Step2: I create file ehcache.xml, copy to $TOMCAT_HOME/webapps/ROOT/WEB_INF/classes

Code:

<?xml version="1.0" encoding="UTF-8"?>
 
 <ehcache name="myCache">
   <defaultCache
       maxElementsInMemory="10000"
       eternal="false"
       timeToIdleSeconds="120"
       timeToLiveSeconds="120"
       overflowToDisk="true"
       diskSpoolBufferSizeMB="30"
       maxElementsOnDisk="10000000"
       diskPersistent="false"
       diskExpiryThreadIntervalSeconds="120"
       memoryStoreEvictionPolicy="LRU"/>
   <cache name="myCache"
          maxElementsInMemory="100"
          maxElementsOnDisk="0"
          eternal="false"
          timeToIdleSeconds="120"
          timeToLiveSeconds="0"
          memoryStoreEvictionPolicy="LFU">
     <terracotta/>
   </cache>
   <terracottaConfig url="192.168.2.202:9510"/>
 </ehcache>

Step3: i start terracotta server
Code:

./start-tc-server.sh -f /home/administrator/Terracotta/terracotta-ee-3.6.2/tc-config.xml

Code:

<?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-4.xsd">
  <servers>
    <server name="server1" host="192.168.2.202">
      <data>/home/administrator/terracotta/server-data</data>
      <logs>/home/administrator/terracotta/server-logs</logs>
    </server>
  </servers>
  <clients>
    <logs>/home/administrator/terracotta/client-logs</logs>  
  </clients>
 </tc:tc-config>

But when i startup Liferay, then tomcat not connect to terracotta server .
Log startup liferay

 note The full stack trace of the root cause is available in the Apache Tomcat/7.0.23 logs.
 
 Apache Tomcat/7.0.23

I'm pretty sure that AbstractMethodError is trying to tell you that liferay's integration with ehcache is expecting an earlier ehcache version or something along those lines.

Thank teck. I try copy ehcache 2.4.2, but it not work.
How to fix ?

When you used 2.4.2 did you get the exact same error (AbstractMethodError)? Can you post the stack trace again so I can verify some line numbers?

Thank teck.
When i use ehcache-core-2.4.2.jar and ehcache-terracotta-2.4.2.jar, startup ok, website liferay runing, no error.
However, function Ehcache in Terracotta console is disabled ?. Function Session run well (I have installed web-session previous).
Note: I use terracotta-3.6.2.

Please help me/

If i remove session files (terracotta-session-1.2.2.jar, terracotta-toolkit-1.5-runtime-4.2.0.jar), Terracotta console as below picture:
Terracotta server not connect client.

Log startup Liferay:

From the information you're sharing it sounds like your caches are not actually getting configured to be <terracotta> clustered.

I do not know the specifics of how liferay uses ehcache internally. In particular I'm not sure if uses a different resource path for the ehcache.xml or if they base things of the <defaultCache> or not.

One quick thing you can test is to put a syntax error in the ehcache.xml you think is in use. If you get an XML parse exception you know you're at least changing the correct file. If you at least have the cprrect config file you probably need to dig into liferay code/documentation a bit to get a handle on how to configure ehcache in it.

Thank teck.
when i put a syntax error in the ehcache.xml (insert more </ehcache> in ehcache.xml or delete all content in ehcache.xml), Liferay startup ok, runing, not error ?
I sure liferay not getting configured to be <terracotta> clustered.
I have reference "setup cluster Liferay with terracotta":

Code:

EhCache and Hibernate Second Level Cache
 
 1. Remove ehcache.jar that is bundled with Liferay (located in TOMCAT_HOME/webapps/ROOT/WEB-INF/lib)
 2. Copy all jars in TERRACOTTA_HOME/ehcache/lib to TOMCAT_HOME/webapps/ROOT/WEB-INF/lib
 3. Copy TERRACOTTA_HOME/common/terracotta-toolkit-1.0-runtime-<version>.jar to TOMCAT_HOME/webapps/ROOT/WEB-INF/lib
 4. Create my-ehcache folder to TOMCAT_HOME/webapps/ROOT/WEB-INF/classes
 5. Create a hibernate-terracotta.xml and a liferay-multi-vm-terracotta.xml.
 6. Adjust terracottaConfig in hibernate-terracotta.xml and liferay-multi-vm-terracotta.xml to point to your Terracotta servers. Like this: <terracottaConfig url="localhost:9510"/>
 7. Add following properties to your portal-ext.properties file:
 ehcache.multi.vm.config.location=/my-ehcache/liferay-multi-vm-terracotta.xml
  net.sf.ehcache.configurationResourceName=/my-ehcache/hibernate-terracotta.xml
  hibernate.cache.region.factory_class=net.sf.ehcache.hibernate.EhCacheRegionFactory
