Thanks! that problem is solved. Thank you again!

Hi,
I am facing a weird problem.
Please tell me where to place the ehcache.xml so that the web-application can find it.

I am always getting this error when I try to access ehcache.xml

Please help!

I wish to setup Ehcache, Terracotta server to work on one machine (single instance) for the time being.

My tc-config.xml looks like 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-6.xsd">



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

<data>/mnt/terracotta/server-data</data>


</server>








</servers>
</tc:tc-config>

---------------------------------

And ehcache.xml inside Flume classpath has the following config:

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

<ehcache name="RTLogCacheManager">

Please help. DOes any of the logs tell of any error. I could not find any error logs as such.
Do I need to check any more log locations(I am not aware of!).

Please help!

No sir. I am using Enterprise Ehcache as L1 cache for Terracotta and using the 30 days license. Please help

Hi,
I have 4 servers. Two of them are active and two passive. Do i have to have password-less authentication on all servers in order to have distributed setup of ehcache?

When I check the logs for flume for which terracotta is a client, I am getting the following INFO logs at the end...its in bold. Can you help?

========This is a new post====

In ehcache, I am getting a weird error!

"java.lang.RuntimeException: java.lang.AssertionError: Looking up in the wrong Remote Manager :".

Not sure why the error is coming. Flume is using Ehcache as "sink", to feed data. Terracotta L1 cache -> ehcache.

Where do I need to check. Please help.

The error "2012-12-12 03:33:00,465 WARN net.sf.ehcache.Cache: Performance may degrade and server disks could run out of space!
The distributed cache RTLogCache does not have maxElementsOnDisk set. Failing to set maxElementsOnDisk could mean no eviction of its elements from the Terracotta Server Array disk store. To avoid this, set maxElementsOnDisk to a non-zero value. " is resolved.

Now, "java.lang.RuntimeException: java.lang.AssertionError: Looking up in the wrong Remote Manager ". I don't know what is the problem.

Now, I am having the following message on flume node log

Can you please help?

I was wondering what could be the terracotta client now?
I have flume which takes as a source, a text file and sends data to ehcache.
So, is TC client "ehcache" which is co-located with Flume on a single node?

Then what is the classpath for the TC client? I had included the license key at the Flume classpath via flume-env.sh. Still getting the same error!

What is supposed to be the classpath that you had mentioned. Please help?

Hi,

I am having a weird problem with terracotta. It says that
"2012-12-11 08:11:05,435 INFO - Terracotta Enterprise 3.6.1, as of 20120125-122228 (Revision 15328-19619 by cruise@su10vmo104 from 3.6.1)

But, when I look at the logs for Flume(which is configured to use Terracotta -Ehcache) at "usr/lib/flume/logs-10.40.222.77/terracotta-client.log"

I get this error:
"2012-12-11 07:31:13,909 [logicalNode ec2-75-101-165-36.compute-1.amazonaws.com-19] ERROR com.terracottatech.console - Terracotta license key is required for Enterprise capabilities.

And, when I see the logs at "/var/log/flume/flume-flume-node-ip-10-40-222-77.out", I get the error as

"2012-12-11 07:31:13,909 ERROR - Terracotta license key is required for Enterprise capabilities. Please place terracotta-license.key in Terracotta installed directory or in resource path. You could also specify it through system property -Dcom.tc.productkey.path=/path/to/key".

I downloaded the correct key and placed it at /mnt/terracotta-ee-xxx/ directory, as well as instructed by the Terracotta site.

Please help. I am not able to find the solution !

is there some server that I need to start ? I don't get the idea..how to configure ehcache...i have two unix boxes..i have to configure ehcache to be available on these two machines in a cluster (or what is called configuring ehcache in a distributed mode)

also we have to keep in mind that I am not using Terracotta server as L2 cache...am replacing it with HBase..how to do that??

I am a newbee in EhCache. I want to read a file and insert data into EhCache. How to do that?
