Hi.
I am trying to connect from xMII version 12 til SAP using JRA. Does anyone know a function call that enables me to se the exact servername or something like this, enabling me to verify whether I am connecting to an exact server or not?
Is it correct, that I need to specify these params when connecting to SAP Cluster?
MessageServer=b20main,
SystemID=B20,
Group=PUBLIC.
Somewhere I have seen that Group should be enough?

Hi Sam.
I got a little further, but not all the way yet. From JRA file, I think I need to replace ServerName with MessageServer along with a couple more. I also found a debug flag to set. And I found a message about adding a line to services file within c:\windows\system32\drivers\etc.
But not there yet. I am verifying my SAP data and when getting there, I will post the hints on this threat.

Hi Poul and Sam,
Please do the following to enable the JRA in xMII 12 to use the message server and logon group to backend ERP:
In Backup ERP:
- Create logon group in SMLG transaction for the instances you want the xMII JRA to connect to.
xMII:
- Deploy SAPJRA.RAR
- Remove ServerName and PortNumber as you want to use the Message Server
- Add parameters: MessageServer, SystemID, and Group with values:
Message Server - Virtual Hostname of the backup system for cluster
SystemID - SID name of the backup ERP
Group - Logon group created in SMLG transaction
- In the xMII service file, add the entry "sapms<ERP SID> 36<system number of ERP>/tcp'.
- Stop and restart xMII. You will also need to stop and restart the windows service for xMII too.
Thanks,
Van Vi
A few more hints, the quick version
JRA via BLS logfiles are usually placed in
C:\usr\sap\<SID>\JC00\j2ee\cluster\server0\, in my case called dev_rfc.trc.
JRA Connections can be found and verified with the following tool.
http://localhost:port -> Web dynpro -> Web dynpro console -> Jco connection pools.
In Visual administrator -> Server0 -> Services -> Connector container -> Your JRA name. Select the connection name belov and select tab Managed connection factory, then properties.
Here you can add one of the following
Trace - Enable/disable trace on all middleware layers(true or false). On default is false.
TraceRFC - Enable/disable RFC trace (true or false). On default is false.
TraceJCO - Enable/disable JCO trace (0 for none, 10 for highest level). On default 0. Type Integer.
TraceJRA - Enable/disable JRA trace (0 for none, 10 for highest level). On default 0. Type Integer.
Which enables further logging, also found in the dir.
C:\usr\sap\<SID>\JC00\j2ee\cluster\server0\.

Poul,
From what I know about the JRA, which is no very much, the group should be all you need...I mention this in the NW Install Pre-Release Guide that I sent to you.
