Hi,

First of all go to this url:

http://<servername>:<port>/sld

Administration-->Content Maintenance

Now remove all the entries for the system that you created from (all the entries with the system ID for your backed system)

Application system instance

BC Application server

BC Client

BC Message Server

BC System

Computer System

Global Unique Identifier

Installed System

Installed Software Component

TCP/IP Server Port.

Now, make these entries

SID == system id of your backed system (3 digit aphanumeric)

MESG SEVER PORT ===36<instance number>

to add application server

application host name == Don't add anyting over here. Click Next

application instance number == <instance number>

client number ==<client number>

logical client name ==Not mandatory

Hi samyukthav,

The client number seems important to me. Maybe it is 00 but to leave it empty doesn't seem like a good idea to me.

Hi,

You were suppose to provide the instance number . Please provide that and try to ping and test it. If you are still facing the error please provide the error so that we can look into it.

What you are asking about ?

creating Technical System

or creating JCo

Please specify your need.

You can't proceed without host, instances in technical system creation wizard.

If you are creating JCo for an existing R/3( which has a working JCo right now), you have to check the JCo connections and technical systems.

If NOT, check your sap message server entry is in your services file.

this reply is to what i understood from your question. tell me if you have any query

i want to use jco

but for that we need to create a techinical system

i followed these steps for techinical system

1 Step

selected web as abap

2nd step

sid = PRD

installation number== INITIAL

database host name== super

3rd step

message server name = 3600+instance

i took system number from sap gui(21)

so i gave 3600+21=3621

central application sever

instance number ==21

next pressed button -->add new logon group

entered longon group == entered value

which i found in t-code -smlg

4th Step

Add application server

host == gave r/3 ip 198.168.0.2

instance==21

client number = 800

logical client = left it empty

5 th step

selected one componenet and finished

-

---

after this i created the jco

1st Step general data

name =test1

client=800

2nd step j2ee cluster

checked the box

use local j2ee engine

3rd step

selected dictionary meta data

4 th

selected the techinical system

5th

user name -->sapuser

pasww-->india

pressed finish

now i found the jco in green color

but i pinged it

i got mesg

ping failed

Hi,

installation number== INITIAL

This should be some digits.

Login to your R/3 System and select System-->Status.

Here you can find the installation number. Provide the same.

hi samyuktha!

in Tech.System check for these :-

1. database server: host (system name)

2. 3rd step

In t-code SMLG, You have to check Group name assignment "ext-RFC enabled" checked.

- you can check your group is working fine by following command

- go to sap GUI installation directory using command prompt

sapgui /M/<host>/S/3621/G/<GROUP_NAME> and hit enter. This will open sapgui.

3. 4th step

Logical client: <SID>CLNT800

4. 5th step

Choose product: SAP WEB AS 6 or 7 which ever latest version available, and you can choose all SWC from the right column.

JCo Connection:-

1. be specific on naming conventions

eg: WD_<your_string>_RFC_METADATA_DEST

WD_<your_string>_MODELDATA_DEST

2. choose J2EE server from the list

you can find similar like J2EE on <host name>

3.

3.1) for METADATA, it is application and select single server from the right

-> Application server will be available in the dropdown list.

it is a combination of <host><sid><instance> separated by underscore.

once it is created, do a test. it will be okay.

If it gives error testing application data, go to R/3 and run this report rsrzllg0_actual without checking FRC_SAV option.

again check your JCo destination.

3.2) for MODELDATA, choose dictionary and do the rest of things as above (ignore single/Load balancing)

It needs message server entry in your services file. check for sapms<SID> 3621\tcp entry in services file else put that entry.
