CA PPM - Multicast - Discovered Clients None

Hi All,

 

I've read a lot on the subject but I still encounter an issue on Multicasting in a client configuration (cluster of 2 servers).

 

Context :
- CA PPM Version : 13.3.0.7.8 (13.3 Patch 7)
- OS : Windows 2008R2 Service Pack 1
- Hostname : 2 servers QPAGCE8V2032 (126.246.153.36) and QPAGCE8V2033 (126.246.153.37)
- Multicast IP : 239.0.1.25 on Port 9090

- No Firewall on both servers

 

I can make the connection between the 2 servers (both ways) with the library jgroups-all.jar.

 

Example with 2032 as Master and 2033 as Slave.

 

1/ Sender 2032

java org.jgroups.tests.McastSenderTest -mcast_addr 239.0.1.25 -port 9090 -bind_addr 126.246.153.36
Socket=0.0.0.0/0.0.0.0:62630, ttl=32, bind interface=0.0.0.0/0.0.0.0

3

2/ Receiver 2033

java org.jgroups.tests.McastReceiverTest -mcast_addr 239.0.1.25 -port 9090 -bind_addr 126.246.153.37
Socket=0.0.0.0/0.0.0.0:9090, bind interface=0.0.0.0/0.0.0.0
1 [sender=126.246.153.36:62630]
2 [sender=126.246.153.36:62630]
3 [sender=126.246.153.36:62630]

 

I can see both servers on the CSA console but when I use the admin tower command, I see Discovered Clients: None.

> admin tower

Discovered Clients:

None

I've made the following tests :

- Use of another IP Address in the scope 239.0.1.25

- Use of another Port other than 9090

- Reset of the CSA password on both servers

- Change of the order of NIC in the Network Advanced Settings (a bit tricky on Windows)

- Change of the Bind Addresses on both servers (126.246.153.36,126.246.153.37, 126.246.153.36 alone, 126.246.153.36,126.246.153.37 alone or null values)

 

I don't see the key word "MULTICAST" on Windows command ipconfig / all (I always see it on RHEL). I don't know it it's important or not for CA PPM ?

> ipconfig /all
