question on RFC's between XI and TREX for CCM 2.0 distributed scenario

[Former Member]

Hello all,

I have a question which RFC connections are necessary between XI 3.0 and TREX 7.00 in a CCM 2.0 distributed scenario?

EBP and CCM are on different clients on the same SRM 5.5 server, the XI is on a second server, and the TREX search engine is on a third server.

I have configured the XI with the CatalogPublicationOnWAS700 scenario and have the following RFC connections configured and working:

R/3 connections: XI to EBP, XI to CCM, CCM to XI, CCM to EBP, EBP to CCM, EBP to XI

HTTP connections: XI to CCM, CCM to XI

TCP/IP connections: CCM to TREX, CCM to XI (SAPSLDAPI & LCRSAPRFC)

What I'm missing are HTTP connections between XI and TREX. I this correct in this scenario? Do I have to delete the HTTP connections between XI and CCM?

I am asking because I get an ICM_HTTP_CONNECTION_FAILED error at the plain http adapter in the XI when I try to post a catalog.

If anyone has a configuration guide/documentation for my scenario described above, could you please send it?

Best regards,

Karsten

Hi Karsten

You need 2 HTTP connections from CCM to XI.

1) XI Integration server

2) Plain HTTP adapter (path prefix = /sap/xi/adapter_plain)

Hello Ramki,

thanks for your help. I will test it next week when I'm back and have access to my system again.

I will not forget to assign points!

Best regards,

Hello Ramki,

sorry for the late answer, but I was abroad without access to my system.

I already have two HTTP connections (type H) from CCM to XI: one plain http adapter (path prefix: /sap/xi/adapter_plain) and one general (path prefix: /sap/xi/engine/?type=entry).

Unfortunately that doesn't work.

My guess now is that the http receiver channel that was generated automatically for the TREX system in XI during import/configuration of the scenario CatalogPublicationOnWAS700 has missing data because of the error type ICM_HTTP_CONNECTION_FAILED.

I get this error, too, when I create a http connection from XI to TREX with the same data.

In this generated http receiver channel I have the follwoing data:

adapter type: HTTP

receiver

transport-protocol: http 1.0

message protocol: XI payload in http body

adapter engine: Integration server

address type: URL-address

server: <IP address>

service: 8001

no path prefix.

Maybe the path prefix is missing, but I found nowhere what to enter here.

Regards,

Karsten

Karsten, please refer to the following document for CCM technical setup, including connectivity:

Hello Serguei,

thanks for the link, but I already have this cookbook. It doesn't tell details on the distributed configuration so I did not solve my problem.

Best regards,

Karsten
