Terracotta Discussion Forums (LEGACY READ-ONLY ARCHIVE)

Hi.

I'm diving in at the deep end with TC 3.7.0 and ehcache trying to set up a redundant cluster across 3 nodes. I seem to bring up the cluster nodes OK, but when running the client I receive errors like this:

Code:

 *******************************************************************************
 The configuration data in the base configuration from server at 'w2-gst-m3k-02:9510' does not obey the Terracotta schema:
   [0]: Line 10, column 5: Attribute not allowed (no wildcards allowed): secure in element servers
 
 *******************************************************************************

Looks like a XML validation error.

Part of my tc-config.xml looks like this:
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-6.xsd">
 
   <servers>
     <server host="w2-gst-m3k-02" name="server2a">
       <data>/tmp/terracotta/server2a-data</data>
       <logs>/tmp/terracotta/server2a-logs</logs>
       <statistics>/tmp/terracotta/server2a-stats</statistics>
       <dso-port>9510</dso-port>
     </server>
     ...

Snooping the network to see the config being retrieved I see (in part):
Code:

 <?xml version="1.0" encoding="UTF-8" ?>
 
 <con:tc-config xmlns:con="http://www.terracotta.org/config">
     <system xmlns:tc="http://www.terracotta.org/config" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
         <configuration-model>development</configuration-model>
     </system>
     <clients xmlns:tc="http://www.terracotta.org/config" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
         <logs>/tmp/terracotta/client-logs</logs>
     </clients>
     <servers secure="false" xmlns:tc="http://www.terracotta.org/config" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
         <server host="w2-gst-m3k-02" name="server2a" bind="0.0.0.0">
             <data>/tmp/terracotta/server2a-data</data>
             <logs>/tmp/terracotta/server2a-logs</logs>
             <statistics>/tmp/terracotta/server2a-stats</statistics>
             <dso-port bind="0.0.0.0">9510</dso-port>
             <jmx-port bind="0.0.0.0">9520</jmx-port>
             <l2-group-port bind="0.0.0.0">9530</l2-group-port>
     ...

Sure enough, the 'secure' attribute isn't defined in terracotta-6.xsd.

So, I imagine, that somehow the client isn't using terracotta-7.xsd to validate the returned schema.

Here's my ehcache.xml FWIW
Code:

 
 <?xml version="1.0" encoding="UTF-8"?>
 
 <ehcache name="YCSB">
   <defaultCache
       maxElementsInMemory="10000"
       eternal="false"
       timeToIdleSeconds="120"
       timeToLiveSeconds="120"
       overflowToDisk="false"
       diskSpoolBufferSizeMB="30"
       maxElementsOnDisk="10000000"
       diskPersistent="false"
       diskExpiryThreadIntervalSeconds="120"
       memoryStoreEvictionPolicy="LRU"/>
   <cache name="terraCache"
          maxElementsInMemory="10"
          maxElementsOnDisk="0"
          eternal="true"
          memoryStoreEvictionPolicy="LFU">
     <terracotta/>
   </cache>
   <terracottaConfig url="w2-gst-m3k-02:9510,w2-gst-m3k-03:9510,w2-gst-m3k-04:9510"/>
 </ehcache>

I tried referencing http://www.terracotta.org/schema/terracotta-7.xsd in my tc-config.xml as the schemaLocation, but that file doesn't seem to exist.

Thanks for any insights.

Solved it. I was building my client against ehcache-2.5.2 instead of 2.6.0.

great!!!!
