Victor,

Now the only thing i say you is check that your R/3 system that you are trying to connect to is up and running fine.

Can you please share your BC Message Server settings?

Hi,

Please refer to one thread only

[Former Member · Accepted solution]

r u followin these steps:

1 maintain sld

2 setup cim

3 append hosts file

4 append services file

5 jco ok.

[Former Member · Accepted solution]

I do but not work... The sld test ok, i setup cim, the host and services are append but jco ko...

[Former Member · Accepted solution]

During the SLD configuration, we import CRContent.. This will contain the component list.. Have you imported the CRContent from server ?

[Former Member · Accepted solution]

Yes, i import cimsap.zip and CR_content.zip...

[Former Member · Accepted solution]

You have to mention your ECC system in the technical landscape of your SLD.

Have you done this ? Excecuting the transaction RZ70 will produce the same effect.

Click n technical landscapes in your homepage of sld, new Web AS system and enter the needed parameters.

Its pretty easy. If you get stuck somewhere.. you can post again :).

Once this is done your JCO connection are ready to work .

[Former Member · Accepted solution]

Yes, it´s configured:

- Technical Systems --> New Technical System

- Web AS ABAP

- SID: CER

Installation number: 0020069135

Database Host Name: netweaver

- Mesage Server port: 3690 (with the transaction rz70, in SAP, in msgsrv)

Instance Number: 90

- Add application server --> host name: netweaver

- Client number: 200

- Installed products: Netweaver

Finally appear this error: CIM_ERR_ALREADY_EXISTS: Instance already exists: SAP_BCApplicationServer.CreationClassName="SAP_BCApplicationServer",Name="CER.Number.90.HostName.netweaver"

but the technical system is create and appear the error...

...remove the system from sld and re-creating it.

manually delete all jco-destinations in the sld (are there any yet?)

use logongroup PUBLIC, but i don't know a reason, why SPACE would't work.

you definitely need a logongroup for logging on to a message server, since the meta-rfc demands a message-server.

then restart ur machine....hope it works

Don´t work i remove de technical system, i import the two files, i delete de jco, i configure a technical system, i configure a jco but don´t work: com.sap.mw.jco.JCO$Exception: (102) JCO_ERROR_COMMUNICATION: JCO.Client not connected in repository call

I found the solution, I change the ip of server this way:

i go to "Content Maintenance", select "Application System Instance", i select the application that want change the ip, in the top select the "Associated Instances", select "Application System Instance Host", select the "Antecedent" that i want change the ip and now can change the ip...
