Virtual Machines: Problem connecting to 3900 port

[Carles Viaplana]

Hello,

We're installing SAP PI into HP-UX 11i Virtual Machine.

In one of installation steps system tries to open to itself a connection through 3900 port and we get the following error:

INFO 2007-09-20 10:33:01 [iaxxcmsclient.cpp:112]
CIaMsgClient::CIaMsgClient(mabra125, 3900)
Connect to message server (mabra125/3900) succeeded.

INFO 2007-09-20 10:33:01 [iaxxcmsclient.cpp:122]
CIaMsgClient::~CIaMsgClient()
Disconnect from message server (mabra125/3900) succeeded.

We have installed SAP PI into another virtual machine and it works fine with 3900 port.

Could issue be due 3900 port is already in use by other virtual machine?

I suggest it because we got scsi issues and virtual machines as they couldn't use and see it at same time.

Any idea?

Thanks in advance for your help.

Regards,

Carles

I suggest installing LSOF and seeing what process is using port 3900.

As a check netstat -an|grep 3900 then check /etc/services to see if there is a defined service for 3900.

If you are using IVM then each virtual guest is it's own segregated server and OS just like if it was on its own hardware.

No, because the NIC on the host works like a switch.
Maybe there is another network issue.

Regarding the SCSI related problems: someone has to have a closer look to your config.

Restarted server and all is working fine again.
