Hi,

I just installed openemm 2011 with a remote mysql server. To do this I changed the following parameters :

~/WEB-INF/classes/emm.properties:jdbc.url=jdbc:mysql://auchan-sql02o.vmut93.cvf/openemm?useUnicode=yes&characterEncoding=UTF-8&useOldAliasMetadataBehavior=true
~/WEB-INF/classes/cms.properties:cmsdb.url=jdbc:mysql://auchan-sql02o.vmut93.cvf/openemm_cms?useUnicode=true&characterEncoding=UTF8&jdbcCompliantTruncation=false

All works fine except when I click on the Heatmap button, in the mailing statistics, where i get this error :

Code: Select all

An error occurred
Cause:	org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

It seems OpenEMM tries to connect to a local mysql server as it works when I make an ssh tunnel towards my sql server on port 3306

Is there another configuration file I missed to specify my sql server ? I searched within this forum with no luck.

Thanks for your help...

You may have to adjust the ecs property in file emm.properties.

Hi,

Thank you fro replying, maschoff. Are you talking about the "ecs.server.url" property? Right now, it looks like :

Code: Select all

ecs.server.url=http://openemm.mydomain.com

What should I replace this with ? Anyway, I'm not convinced it is the solution, because the problem seems to be mysql related. With tcpdump, I see OpenEMM trying to connect on localhost:3306 instead of the mysql server I defined both in emm.properties and cms.properties.

The database connection for ECS is defined as JNDI resource in Tomcat configuration file context.xml. Did you change property url of tag resource there?

Hello,

After changing context.xml, the mysql database connection is now working.

Now I have another issue, but I'll open a new thread...

Thanks a lot for your help.
