During some issues with hanging messages in some communication channels I noticed that messages for other receivers were also on hold. So adapter engine was processing all messages EOIO while Integration Server does that per receiver.
I found the [solution in the SAP Help |http://help.sap.com/saphelp_nw04/helpdata/en/45/13b942f14d29efe10000000a114a6b/content.htm] but I am not able to access the mentioned link: http:// /MessagingSystem/migration.jsp
Error message I got is: 404 not found.
Looks like something changed! I checked some simular links like http://<host>:50000/MessagingSystem/monitor/monitor.jsp and that works fine.
(I also checked the role SAP_XI_ADMINISTRATOR_J2EE was included in my userprofile)
Please help me finding what I do wrong...or what has changed.
