Hi
Is there any fix for CDV-671. Looks like I am getting the same exception
2008-08-01 18:32:17,113 INFO - Terracotta 2.6.2, as of 20080626-150605 (Revision 8952 by cruise@rh4mo0 from 2.6)

**************************************************************************************
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.

You just need to specify different directories for the servers running on the same host.
Look in the docs/tc-config-reference.xml file for the xml stanzas you need to change the directories for the logs, data, and stats for each server (there should be an entry in your servers section for each server)
So you should have something like:
<servers>
<server name="server1">
.... <- directories for data, log and stats set
</server>
<server name="server2">
... <- directories for data, log and stats set DIFFERENT THAN SERVER 1
</server>
</servers>
CDV-671 covers a different problem than you are having.

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

You need to increase the permgen memory for Weblogic by adding this jvmarg: -XX:MaxPermSize=128m to Weblogic startup script.

Oh, then you will need to setup a clients section. You can pass in an system variable to the java process. See here for details:
http://www.terracotta.org/confluence/display/docs1/Configuration+Guide+and+Reference#ConfigurationGuideandReference-ConfigurationVariables
For example, use:
<clients>
<logs>%(my-location)/logs</logs>
<statistics>%(my-location)/statistics</logs>
</clients>
and start one client with :
java -Dmy-location=/foo/bar1
and the other:
java -Dmy-location=/foo/bar2
Or you could just use a timestamp (%D)

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
TC_INSTALL_DIR=/VZ/opt/terracotta-2.6.2
DSO_BOOT_JAR_NAME=dso-boot-hotspot_solaris_150_16.jar

SunHttpHandler=true $TC_JAVA_OPTS_PRE_SRV_02"
# server-specific override of SERVER_JAVA_OPTIONS
SERVER2_MIN_HEAP=512
# server-specific override of SERVER_MIN_HEAP
SERVER2_MAX_HEAP=512
# server-specific override of SERVER_MAX_HEAP
Those actually set all the Java options for me
