I set it up slightly different
I took two tc-config file
tc-config1.xml and tc-config2.xml
Here's how they look
This is the only difference they have otherwise everything is same

<clients>
<logs>%(user.home)/terracotta/client-logs-pre-srv-01</logs>
<statistics>%(user.home)/terracotta/client-stats-pre-srv-01</statistics>
</clients>
and
<clients>
<logs>%(user.home)/terracotta/client-logs-pre-srv-02</logs>
<statistics>%(user.home)/terracotta/client-stats-pre-srv-02</statistics>
</clients>

Since I am using SSI. So I set up environment variable using SSI. Here how they are

I have only one terracotta Server running on one machine and two managed weblogic servers both on another machine. First managed server starts fine but second gives this exception. Could you please help find this solution. I have given the of the settings which I am using for each manage server

Thanks

Hi
Is there any fix for CDV-671. Looks like I am getting the same exception

The statistics buffer couldn't be opened at
'/apps/opt/weblogic/terracotta/client-stats-pre-srv-02'.
The CVT system will not be active for this node.

A common reason for this is that you're launching several Terracotta L1
clients on the same machine. The default directory for the statistics buffer
uses the IP address of the machine that it runs on as the identifier.
When several clients are being executed on the same machine, a typical solution
to properly separate these directories is by using a JVM property at startup
that is unique for each client.

For example:
dso-java.sh -Dtc.node-name=node1 your.main.Class

You can then adapt the tc-config.xml file so that this JVM property is picked
up when the statistics directory is configured by using %(tc.node-name) in the
statistics path.

Hi
I am trying to run two managed server instances on same solaris box. With one server instance it works fine but the second doesn't start. What configuration changes are required to run two managed server instances one one machine.

I changed startweblogic script file for managed servers but apparently its not able to resolve DSO_BOOT_JAR. Here's what I changed in startWeblogic
TC_INSTALL_DIR=/usr/opt/terracotta-2.6.2
TC_CONFIG_PATH=$TC_INSTALL_DIR/tc-config-weblogic.xml
${TC_INSTALL_DIR}/bin/dso-env.sh -q

and this is how I start Weblogic

I am able to connect to server on unix using Terracotta Administrator Console and it looks like client is not connecting with terracotta server. I am using weblogic 9.2 on sunOS. weblogic is configured to have admin server and two server instances pre_srv_01 and pre_srv_02. Server section of the tc-config-weblogic.xml is like
<servers>
<server host="113.256.128.220" name="113.256.128.220:9510">
<data>%(user.home)/terracotta/server-data</data>
<logs>%(user.home)/terracotta/server-logs</logs>
<dso-port>9510</dso-port>
<jmx-port>9520</jmx-port>
</server>
</servers>
and here is what I have added to admin server stratup script

TC_INSTALL_DIR=/usr/opt/terracotta-2.6.2
TC_CONFIG_PATH=$TC_INSTALL_DIR/tc-config-weblogic.xml
${TC_INSTALL_DIR}/bin/dso-env.sh -q
export JAVA_OPTS="$TC_JAVA_OPTS $JAVA_OPTS"

I don't see any exception but its not connected to Terracotta, another things which proves it is it doesn't generate client log on terracotta server machine. Do you see anything surprizing in the configuration

Thanks for the help

*************************************************************
Looking at the message I assume weblogic is able to comminicate with terracotta but I don't see client logs which is bothering me.
I can not run admin tool because I have text only access to unix machines

I don't see any client log, Does that mean there is no client communicating with terracotta server. In tc-config.xml the location for the client log is specified with
<clients>
<logs>%(user.home)/terracotta/client-logs</logs>
</clients>

Hi
I am new to terracotta and trying to run some tests with weblogic on UNIX. My questiuon is how do we check logs and status of terracotta when there is no GUI support. I tried to server logs and statistics but they look like binary files.
