Maximum RFC connections in RFC

Hi all,
i am facing a problem while trying to send lots of messages from R3 to XI via RFC Sender Adapter:
See the SM21 log in sender system: (R3):
Communication error, CPIC return code 027, SAP return code 677
> CPI-C function: CMINIT(SAP)
anf if i go to the work process log in sm50 (still in R3):
LOCATION    SAP-Gateway on host sp-xxx / sapgw01
ERROR       timeout during allocate of registered program
TIME        Tue Nov 18 10:57:12 2008
RELEASE     700
COMPONENT   SAP-Gateway
VERSION     2
RC          677
MODULE      gwr3cpic.c
LINE        1847
DETAIL      TP ZRFCSENDER_xxxxx init/busy for more than 60 sec
COUNTER     4477
However, nothing is shown in sm21, neither in SM50...
The program ID is registered in SMGW and the maximum RFC connections in RFC_Sender_Channel is set to 100 (although i think that the limit is 50)
When the customer executes the interfaces, they get following 30% with this error (up to 3000 messages in 2,5 hours)
Could you please help in sorting this issue out?
Thanks a lot in advance and best regards,
david

it was a matter of the gateway, we needed to set the gw reg program parameter to a higher value!

PI' RFC Connection pool doubt.

Hi PI exports:
i have a doubt about pi' RFC Connection pool ,pi RFC receive channel can set the conn pool size ,but when start the rfc receiver channel ,is there always only one Connection pool ,or there is only one Connection pool instance?
thinks
Edited by: kevin liang on Oct 19, 2009 6:45 AM

Hi,
Connection poolins size means how many number of connection you want to make open to send data to ECC, We can define maximum number of connection in Receiver RFC Adapter,Go to additional parameters section and define Max Number of connection give the number there,thats it.Internally it works as Connection poolin mechanism.

Raj

STMS: RFC error: Error when opening an RFC connection

Hello ,
I was wondering if you could help me with this TMS issue.
The transport system is not working properly.
The fallowing error is shown:
Could not start transport control program tp
RFC error: Error when opening an RFC connection
There was an attempt to start the transport control program tp using the local RFC interface. An error occurred here.
Error code: 3
RFC error text: Error when opening an RFC connection
Meaning of the error codes:
03 RFC system failure
04 RFC communication failure
System Response
The function terminates. Details about the error can be found in the trace file of the Gateway Monitor (SMGW).
Procedure
Contact your system administrator or use report RSTPTEST to localize the error. You can then execute the command again.
When I test the tp tools:
tp Call and RFC Ping: Error when opening an RFC connection
Another thing would be that when testing the RFC connection CALLTP_Linux I have the error:
ERROR: user XXX is not authorized to start TP /usr/sap/SID/DVEBMGS53/exe
And I have to say that the user has maximum authorizations.
I also checked the permissions of the tp at OS level but everything seems to be ok.
Can you help me with this?
BR,
Manoliv

Dear Manoliv,
Firstly please check if you have enough space in /usr/sap/trans file system.
If OK, please run RSTPTEST report from SE38 and check the log file in SMGW => Goto => Trace => Gateways => Display file
and paste the log here.
Also, I assume filesystem permissions are OK.
Regards,
Sujit.

WHY do we set up a RFC connection for workflows

Guys please tell me why do we setup a RFC connection for workflows.
I am getting few dumps for function module IDOC_ERROR_WORKFLOW_START_R in transsactional RFC connection.
Looks like it is because of temporary disconnection.
i want to know what is the relationship of RFC with wirkflows.
Thanks in advance

Quoting text in automatic WF customizing transaction (SWU3):
Function
The workflow runtime system always executes its tRFC (transactional RFC) calls on the logical destination WORKFLOW_LOCAL_xxx (xxx stands for the three-digit number of the client).
The workflow runtime system only operates within one client. The naming for the logical destination guarantees that these names are unique across the system.
If you carry out this activity automatically, the logical RFC destination WORKFLOW_LOCAL_xxx is created (if it does not already exist). The user WF-BATCH (system user) is assigned to this destination.
If you belong to the SUPER user group, and the WF-BATCH user does not exist, it is created and automatically gets the maximum authorization of the current user (SY-UNAME). This function is to be performed once by a user who belongs to the SUPER user group.
If you perform this activity manually, you can maintain another system user and another password.
In SWU3 you can configure RFC destination.

Number of remote RFC connections to SAP from third party application

Hi All,
We are using an external application which is using the JCO API to make a connection to the SAP server to pass invoices. But the connections are note properly closed after invoking the RFCs and SAP seems to be not able to handle further requests once the numer of connections reach the maximum limit.
Could you tell whether there is a max limit on the number of connections opened to SAP from remote function calls from a third party product?
Is there anyway by which we can make sure that connections are properly closed in SAP after the each remote call?
Thanks in advance for your pointers.
Regards
Arun

Dear Arun,
Here are the parameter settings which you can do to set up RFC connections to SAP servers.
http://help.sap.com/saphelp_nw70/helpdata/en/c3/ce70a5cf0ab1499bfbf464e6e92de0/frameset.htm
This will resolve all your problems.

RFC connection error for PS_ACCESS_1 and PS_ACCESS_2

dear all,
i have created the RFC destination PS_ACCESS_1 and PS_ACCESS_2 with TCP/IP. i also installed WDPS* files in *sapgui\ps\access folder. now i m checking for 'TEST CONNECTION' in sm59 for PS_ACCESS_1 and PS_ACCESS_2 but it is giving 'Error when opening an RFC connection' this error. pls suggest the solution for this problem.
am i missing any other settings? i m using SAP ECC 6.0. is it comfortable with this? is it required any configuration from basis side?
regards,
vicky.

HI,
please check the RFC Trace File at SM59 -> RFC -> Show trace file.
For better tracing delete the Trace File first and recheck the RFC Dest.

Hi,
Please follow this steps:
Creating RFC Destinations in the ABAP and Java Environment
You need to create the following RFC destinations in transaction SM59 (ABAP) and the Visual Administrator (Java):
u2022 AI_RUNTIME_JCOSERVER
u2022 AI_DIRECTORY_JCOSERVER
u2022 LCRSAPRFC
u2022 SAPSLDAPI
Depending on your client settings, it may be necessary to be logged on your SAP Exchange Infrastructure host as SAP system user with the authorization to maintain customizing tables and to release transport orders. Note, that user "SAP*" or "DDIC" does not have these authorizations.
Maintaining the RFC Connections (Transaction SM59)
1. Log on to your SAP Exchange Infrastructure central instance host.
2. Call transaction SM59.
3. Choose Create.
4. Enter at least the following:
RFC destination: AI_RUNTIME_JCOSERVER
Connection type: T
Description: <your description>
5. Choose ENTER
6. Choose the tab Technical settings and do the following:
a. Select Registered Server Program
b. In the Program ID field, enter: AI_RUNTIME_<SID> where <SID> is the SAP system ID of your Integration Server host. Use uppercase letters only.
c. Enter Gateway host and Gateway service of your Integration Server host. To find out the required parameters:
a. On the Integration Server host, call transaction SMGW
b. Choose Goto u2192 Parameters u2192 Display (see entries for gateway hostname and gateway service)
7. Choose tab Special Options and select the flag Unicode in the box Character Width in Target System.
8. Save your settings.
9. Repeat the steps 3 u2013 8 for the remaining destinations:
Destination
Values
AI_DIRECTORY_JCOSERVER
Program ID: AI_DIRECTORY_<SID>, where <SID> is the SAP system ID of your SAP XI host
LCRSAPRFC
Program ID: LCRSAPRFC_<SID>, where <SID> is the SAP system ID of your SAP XI host.
SAPSLDAPI
Program ID: SAPSLDAPI_<SID>, where <SID> is the SAP system ID of your SAP XI host.
10. Leave the transaction SM59 open for later tests.
J2EE Configuration for the Destinations (Visual Administrator)
1. On your SAP Exchange Infrastructure central instance host, start the J2EE Engine administration tool.
2. Choose Cluster u2192 Server u2192 Services u2192 JCo RFC Provider
3. In the section RFC destination, enter exactly the same program ID and gateway options for AI_RUNTIME_JCOSERVER that you used in the step Maintaining the RFC connection above. Additionally, set the number of processes to 10.
4. In the section Repository, do the following:
a. Enter the parameter for the SAP XI host: Application Server, System Number, Client and Language.
b. For User and Password maintain the login parameters for the user SAPJSF.
c. Select the flag Unicode.
6. Choose Set.
7. Repeat the steps 3 u2013 6 for the remaining destinations:
Destination
Values
AI_DIRECTORY_JCOSERVER
u2022 Corresponding values from SM59
u2022 Number of processes: 10
LCRSAPRFC
u2022 Corresponding values from SM59
u2022 Number of processes: 3
SAPSLDAPI
u2022 Corresponding values from SM59
u2022 Number of processes: 3
Testing the RFC Destination
After you have maintained all RFC destinations in both the ABAP and Java environment, you can check all the connections above as follows:
1. Call transaction SM59 again.
2. Open your RFC destination.
3. Choose Test Connection. No error should be displayed.
This will solve your problem.
Thanks
