Cluster install unable to reach the remote CMS

server administration XI Server Discussion

Hi all,

BI4.1 SP6.
Red Hat 6.4

I’ve installed my BI4.1 SP6 server without problem.
Now, i have to install a second server in cluster.

I launch the setup.sh, and when it ask me the informations of the remote CMS, i have this error :

The credentials are corrects.

SRV2 can ping SRV1.
SRV1 can ping SRV2.

I’ve disable the firewall like this :

service iptables save
service iptables stop
chkconfig iptables off

I’ve try with the IP adress, same result.
CMS port is 6400.

The followed command is running well (from SRV2 to SRV1) :

> curl http://10.xx.xxx.xxx:8080

<!DOCTYPE html>

<html lang="en">
    <head>
        <title>Apache Tomcat/7.0.55</title>
        <link href="favicon.ico" rel="icon" type="image/x-icon" />
        <link href="favicon.ico" rel="shortcut icon" type="image/x-icon" />
        <link href="tomcat.css" rel="stylesheet" type="text/css" />
    </head>
[...]

Do you have any idea ?
thanks,

Hi,

Is the port 6400 open bi-directionally between the two servers?
Can you do

telnet SRV2 6400

on SRV1 and also

telnet SRV1 6400

on SRV2?

Hi,

Thanks for your reply.
I advise you that i’m new on SAP BI4 Administration on Linux. (I always have to work on Windows server before…)

So this is the telnet test from SRV1 to SRV2 :


[root@SRV1 ~]# telnet 10.xx.xxx.xxx 6400 
Trying 10.xx.xxx.xxx...
telnet: connect to address 10.xx.xxx.xxx: Connection refused
[root@SRV1 ~]#

Telnet test from SRV2 to SRV1


[root@SRV2 ~]# telnet 10.xx.xxx.xxx 6400
Trying 10.xx.xxx.xxx...
Connected to 10.xx.xxx.xxx.
Escape character is '^]'.
Connection closed by foreign host.
[root@SRV2 ~]#

I have two different behaviour…
Do you know what can be the reason ?

My two server hosts.allow are like this :

ALL : ALL

And there is nothing in my hosts.deny.

Thanks for your help

Hi,

It looks that there may be a firewall between the 2 servers and the communication on the port 6400 is not bi-directional. Try asking your network guys for a help.

Thank you, i’ve opened a request to the network team.
I will update this thread when i will have an answer of them.

Hi all,

If it can help someone, the problem is solved. It was a server hostname configuration issue.

Server with problem :

hostname --fqdn
> localhost.localdomain.XXX.XXX.com

After repair:

hostname --fqdn
> MachineName.MyCompanyDomain.XXX.XXX.com

You also can see this information on the CMC > Parameters > Cluster > CMS Name : The value between the parenthesis.

Thanks for your help,
Regards

I’m having the same issue while trying to install tomcat to a new node, using SAP BI 4.2 SP6. I’m not clear on where you applied the fix

CMC > Parameters > Cluster > CMS Name : The value between the parenthesis

I don’t see a Parameters option in the CMC. Maybe it changed between 4.1 and 4.2? Also, where did you apply the fqdn? Was it in the hosts file?

We are on version SAP BO BI Platform 4.2 SP5. In CMC => Settings (I don’t see Parameters ?) => Cluster we have 3 entries which all have a value.

The fix is made in the hosts file on the server. For windows operating system, this file is usually located here:

C:\Windows\System32\drivers\etc

There are instructions in the file on how to make entries.
More information is available in SAP KBA 2147881 - How to troubleshoot network communication problems in CMS cluster?

Ahh, got it! Thanks for the clarification.
