Error while creating RFC Jco provider in visual Admin

[former_member182205]

Hi,

I have crated a rfc jco provider in visual admin , I have given all the ECC related details both in registered server AND Spcific application server. In both of these I have given R/3 related details like host of ecc and all.

All i have given correct used ID and passowrd also (I am using my own user id and password in this jco rfc provider). that user id is there in ecc with sap all in profile and in roles also i have given 2 roles for that used id, namely sap_bc_jsf_communication AND sap_bc_usr_cua_client_rfc

Still when i try to start it its giving me error: Error starting bundle

please help

ERROR hostname 'sapecdsrv' unknown

Seems like you need to maintained the hosts file as that server is unknown

Check <drive>:\windows\system32\etc\drivers\hosts or /etc/host

[former_member182205 · Accepted solution]

yes i have already maintained my host file and i am able to ping ecc server also.

Failed using Repository of RFCEngine Bundle abc345, this is also i am getting in trace file. abc345 is my program id of rfc jco

still same error i am getting..

[former_member227283 · Accepted solution]

Hi Rahul,

Still you are getting same error in default.trc ??

System is abap+java or abap and java is installed sepretely ??

If it is seperate java instance, then make a entry of abap system hostname in java system host file .

Thanks

Anil

Can you tell us how many JCO connections you maintain?

Can you try reducing the server count from default 20 to say for example 1 or 2.

[former_member182205 · Accepted solution]

Hi,

I tried changing server count value to 1 and 2 also, bur no success

same error !!!!

[former_member227283 · Accepted solution]

Hi RAhul,

Login to your java host and try to ping the abap host.

1. login to OS of java

2. run command

Ping sapecdsrv

let us know what output you get for above command.

Thanks

Anil
