Hello folks

In my project, we used alfresco as our cms. And i've installed & deployed successfully on one Linux test server.(integrated with mysql in the same server)
Now i need to install alfresco in another server(ip: & integrate it with mysql on another server(ip:

Firstly the TCP link between these two server are all right :

[root@carbon Alfresco]# ping
PING ( 56(84) bytes of data.
64 bytes from icmp_seq=0 ttl=63 time=3.74 ms
64 bytes from icmp_seq=1 ttl=64 time=1.87 ms
64 bytes from icmp_seq=2 ttl=64 time=1.92 ms

After i installed alfresco & changing the file "tomcat/shared/classes/alfresco/extension/" as wiki:


In, the scheama "alfresco_uat" has been already created.

But when i start alfresco, some error messages throw out.
Error message shows below:

21:06:15,197 ERROR [org.springframework.web.context.ContextLoader] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.remoting.rmi.RmiServiceExporter' defined in class path resource [alfresco/emailserver/email-service-context.xml]: Invocation of init method failed; nested exception is java.rmi.server.ExportException: internal error: ObjID already in use

Of course, before start operation, any process of occupying 50500 port has already been killed.

As i follow another same problem, some host info has been added into /etc/hosts as blow, but it seems useless to my case: alfresco     localhost alfresco2

At last, i try to change config file of my alfresco on my local windows XP pc to integrate it with mysql on
No such error message throw out and all are right. Alfresco create tables & application started well.
I got myself confused deeply :(

Could any body help me or give me some suggestion ?
Thank you indeed!
