Hello Guys,
we make the Application Management for a Customer PI System.
Scenario:
- the SAP Gui Connection to the ABAP Stack is routed via SAPRouter and Works fine.
SAP Gui -> our SAP Router -> VPN Box from Customer -> Firewall Customer -> ABAP Stack PI System
- WebAccess its working fine, the Customer use Webdispatcher on every PI Server...
Browser -> VPN Box from Customer -> Firewall Customer -> Java Stack (Port: 5xx00 btw. 81xx (Webdispatcher))
Problem:
Our Problem ist, we can not proceed the Integration Builder or the ESB, the Java Web Start works fine and open the Logon Screen Correctly -> but i fill the Logon Screen with my User name and Password and press Logon come the follwing Error:
"Cannot connect to server using message server: ms://<hostname>.<domain>:8134/P4"
In the Details from the Error Message:
"<hostname>.<domain>:53404 Reason: com.sap.engine.services.rmi_p4.P4IOException:
Cannot open connection to host: <IP-Adress of Central Instance> and Port: 53404"
The Customer says, the Firewall is open with the IP Adresses and P4 Port but i dont think so...
Can everybody help me, or have tips for me! I have checked a lot of OSS Messages (PI High Availabilty etc... its all correct on the System)
Sorry for my bad English 
Best Regards,
Markus
