JCO Create error . Partner cannot be reached

[Former Member]

Hi All,

I was trying to create a JCO DEstination to back end ABAP. I created a RFC Destination in SAP Jco Provider (Java ) and RFC Destionation in ABAP. The connection is successful. The SLD Bridge is maintained in Rz70 tcode.

When i try to create a JCO Destination, it throws me this error.

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=B MSHOST=minisap GROUP=PUBLIC R3NAME=NSP MSSERV=sapmsNSP PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR partner 'minisap:100' not reached TIME Tue Oct 26 17:16:13 2010 RELEASE 720 COMPONENT NI (network interface) VERSION 40 RC -10 MODULE nixxi.cpp LINE 3255 DETAIL NiPConnect2: 192.168.56.101:100 SYSTEM CALL connect ERRNO 10061 ERRNO TEXT WSAECONNREFUSED: Connection refused COUNTER 6

partner 'minisap:100'.

How is this 100 coming. Also is there any mistake in the technical system abap which i created? Please do help me to figure out the issue.

Thanks and Regards,

Divya

Dear Divya,

3600 is your TCP/ SAP System Message Server Port,

As you said that your not able to find the port, can you please telnet from the server--->

login to the server in which your facing issue-->open CMD promt, type this command

telnet hostname 3600

example telnet s300n001 3600.

what is the output >? after this command.

Please even check with T-code SMMS--how your message server looks like?

check with your localdomain suffix ( ask your network team) and check with your computer name ?

Regards

JUDE

error on telnet minisap 3600

Could not open connection to the host on port 3600. connect failed

Hello,

please paste here content of file dev_ms from ABAP server minisap - should be in location /usr/sap/<sid>/<instance>/work

(there you will find if MS is running ok and what port is used)

Hello,

this is thr problem:

Thr 3832 *** I listen to internal port 3900 (3900) ***

Your message server is running on port 3900 - this is not standard SAP port...

You got two choices:

1.) either in services file on Java you need put port 3900 insted of 3600

2.) you will use default port for message server

I suggest second option but it might impact all other applications that are already connected using port 3900.

Can you check on BOTH servers - both ABAP and Java in /etc/services that for sapmsNSP you have same port?

Best regards.

[tomas-krojzl · Accepted solution]

Hello,

as I wrote above - it looks that you use port 3900:

Thr 3832 *** I listen to internal port 3900 (3900) ***

This is not standard port.

Can you please go on BOTH machines into the /etc/services and write down ALL records having sapmsNSP service (from both machines same service).

Also telnet on port should be working - so try on BOTH machines:

telnet minisap 3900

Then on ABAP machine try:

telnet localhost 3900

I believe you got messed ports in services because MS is running on port 3900 while Java is attemting to connect to 3600.

As you wrote before:

But the enrtry is maintained in the service file 
sapmsNSP 3600/tcp.

Best regards.

[Former Member · Accepted solution]

Hi Tomas,

In both machines, only 1 record is maintained n service file for sapmsNSP.

sapmsNSP 3600/tcp

Also telnet is not working in both the machines. Is there some configurations required for this to work.

What else is the solution. Please help in resolving this issue tomas.

Thanks and Regards,

Divya

[tomas-krojzl · Accepted solution]

Hello,

oki on both machines you have:

sapmsNSP 3600/tcp

On minisap machine - was there before port 3900 for sapmsNSP?

Did you change it from 3900 to 3600?

Normally SAP message server should start on port 3600 but your's is started on 3900?

Can you go to transaction RZ11 and display parameter rdisp/msserv - does is showing value sapmsNSP?

Can you go to transaction SMMS then go to menu GoTo / Parameters / Display and check value on row:

server service = ???

server port = ???

I would say you will find there 3900 which is wrong.

In case you changed the port 3900 to 3600 manually - restart of message server is required - did you do that?

Best regards.

[Former Member · Accepted solution]

Hi Tomas,

No before there was no entry for port 3900 or 3600. I manually entered the entry

sapmsNSP 3600/tcp.

After that i have restarted the abap server several times.

In RZ11 and display parameter rdisp/msserv - it does not show any value sapmsNSP. i cannot see any parameter ot value like sapmsNSP....

Can you go to transaction SMMS then go to menu GoTo / Parameters / Display and check value on row:

server service = 3900

server port = 3900

As you said , 3900 is displayed.

My sso with logon ticket is working fine. What is the problem with this JCO. Cant this be rectified tomas. Please do help.

What else should i do?

Thanks and Regards,

Divya

Hello,

try to check if parameter rdisp/msserv is anywhere configured in profiles of ABAP (either default or instance)...

if yes - try to remove all occurences and keep it without this parameter...

if not - try to add value: rdisp/msserv = sapmsNSP

after saving restart SAP - we much get in SMMS following values:

server service = sapmsNSP

server port = 3600

Best regards.

[Former Member · Accepted solution]

Hi Tomas,

That worked. Now in Tcode - RZ11, rdip/msserv parameter is showing value as sapmsNSP. Also the msserv service port is also showing 3600. In dev_ms it is showing.

"I listen to port 3600."

Initially i get this error when i test the JCO.

The group PUBLIC is added. when i select "ext-rfc enabled". this error goes.

Then when trying to test the JCO, it is throwing an error.

Hello,

oki - we are one step forwards - now you need to add following into your /etc/services on Java server:

sapgw00 3300/tcp

Also make sure that there is no other "3300/tcp" in your /etc/services

Then he will know the port that should be used for connection.

Best regards.

[Former Member · Accepted solution]

Hi Tomas,

Sorry for the late reply. didnt know.

There are no other entries in the service file for port 3300. except

sapgw00 3300/tcp.

But how that 100 is coming in place?

Hi,

I executed the Program = rsrzllg0_actual with FRCE_SAV unchecked. I did not getting any message like "Program executed successfully".

But when i tested the JCO i am getting an error

com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Password logon no longer possible - too many failed attempts

For RFC Destination creation in jco rfc provider, i used the user SAPJSF. That user is not locked. i checked at the abap side and also tried changing it with a new password.

For JCO Destination creation i am using the user - BCUSER. With that user i am able to easily login through SAP GUI.

There is no chance of user getting locked or password being wrong as i am using the same password for both the user.

What should be donee for this.

Hi Divya,

Once you execute the Program = rsrzllg0_actual with FRCE_SAV unchecked, you will not get any message. it is Ok.

Please check the thread

While creating and testing the user inside content administrator, i used the user - BCUSER.

Divya,

As you have said that your ABAP & JAVA systems are in different domains & also a telnet to the message server port doesn't work, it implies that this port is somehow blocked in the 2 subnets.

When you configured SSO which connection type did you use - using msg server or direct connection the application server on ABAP side?

Can you also run a telnet to the abap host on the dispatcher port & g/w port (32<instance #> & 33<instance #> respectively) & see if it works?

Great Help!!!Thanks to Tomas, Jude and Arun.

Problem Got Solved. Closing thread.

Mistakes

1. RFC Destination was not created and was not successful both at ABAP and Java Side

2. Message Server was not pointing to the correct port 3600.

3. While Creating JCO Destination, as many blogs specified client as 000, i too gave the default client of Java Server. Instead had to give ABAP Client.

Thanks a Lot.

Hi,

I checked with that software. As the message server port is 3600, i was unable to find the port inside while running the software.

But the enrtry is maintained in the service file

sapmsNSP 3600/tcp.

Also "ping minisap" is working from both source and target system. In SAP MMC, the Message Server status is green. (Running)

What else should be done. Why is that the message server port 3600 not found inside while running the software. Is the message server port no - 3600 correct. NSP instance number is 00.

I mean to say SM59 system number under this location.

Navigate to visual administrator--under Jco RFC provider, I assume that you have created RFC under the name LCRSAPRFC_UNICODE and SAPSLDAPI_UNICODE on the right column under BUNDLES you can find the system details

Specific application server details

There you please check with you ABAP RFC connection details

Application server host: - host name

System number: - example 00

Hi Jude,

SAPJSF user was not created. I created a user SAPJSF and added the role. Used SAPJSF used while i created the RFC Destionation in SAP NWA. Those RFC destinations are working fine in SAP NWA.

But still getting the same error.

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=minisap GROUP=PUBLIC R3NAME=NSP MSSERV=sapmsNSP PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR The message received isn't from a message server.

Please do help in resolving this isssue.

Hello,

I would stick to this message:

The message received isn't from a message server. Are you really connected to the message server? Please check your connection parameters. (minisap / sapmsNSP)

For some reason it looks that you are connecting somewhere but not to message server.

Validate that:

1.) hostname minisap is correct - best perform ssh minisap from source machine and login to be sure you are on correct target machine server

2.) check that port is correct - look in /etc/services (of source Java machine) for sapmsNSP entry - ensure that there is no other entry with same port and compare port used with value specified in profiles of message server on target ABAP machine

3.) validate sap message server is up and running on target machine (because maybe MS crashed and other application is running on this port)

4.) use can use tools like msmon to check directly message server

Hello Divya,

Have you maintained any sap logon group in T-code SMLG, double click on the logon group and click on atributes under gruop independent check whether external RFC connection is checked, if yes pls remove that try it again.

http://wiki.sdn.sap.com/wiki/display/EP/TroubleshootingSAPJavaConnector%28JCo%29

Can you check on the ABAP side have you maintained the wrigth system number in SM59 RFC connection

Regards

Hi Jude,

The External RFC Connection is unchecked. Also where is that in SM59, we specify the System Number.

While creating the RFC destinations, speficied only the gateway host and number. Where can i check the system number in sm59.

Hello Divya v,

Please go through this link to create JCO destination.

http://help.sap.com/saphelp_nw2004s/helpdata/en/be/6e0f41218ff023e10000000a155106/content.htm

And please make sure that you have maintained entries in hosts file and servies

you can navigate to START> RUN>DRIVERS-->etc or C:\WINDOWS\system32\drivers\etc

under hosts file maintain the entries like

192.90.225.62 S320M000 S320M000.abc.cordir.net

IP address hostname FQDN

and check for the entries of services file with the wright ports are in place.

Regards

JUDE.

Hi Divya,

Not sure whether you are trying establish a JCo between ABAP & Java stack of a single system(dual stack like PI) or trying to connect a ABAP stack(ECC) box with pure JAVA stack(like EP). Regarding your error it seems that minisap is referring to your msg server host and whats the client number you mentioned there ..is it 100 ? make sure you are using correct hostname and client information there.

A general JCo connection process is mentioned. From my experience, if you follow the basics clearly then there shouldn't any issue in JCo connection.

You need to create LCRSAPRFC & SAPSLDAPI,AI_RUNTIME_<SID> etc "T" type RFC destinations at ABAP stack. In both the RFCs under technical setting tab select "Registered Server Program" radio button and put Program ID as LCRSAPRFC_<SID> & SAPSLDAPI_<SID>,AI_RUNTIME_<SID> respectively.

In the VA, under JCo RFC provider make sure the following JCos are created :-

AI_RUNTIME_<SID>

AI_DIRECTORY_<SID>

LCRSAPRFC_<SID>

SAPSLDAPI_<SID>

Details at Jco would be as mentioned below :-

Program Id: LCRSAPRFC_<SID>

Gateway host : <server hostname>

Gateway service: sapgw00

Server Count : 3

Repository -> Specific Application Server

Application server host : <server hostname>

System number: <nr>

Client : <xyz>

User :

Password :

After putting the details,when you "set" them make sure the RFCs "run" i.e. successfull at Java end. If you mention program id with correct <SID> of your system then most of the problem occurs with the correct user id/password/Client for JCo.

At ABAP end also connection test should be sucessful.

Hi shivaji,

I am trying to connect a ABAP stack(ECC) box with pure JAVA stack(like EP). I created all the specified rfc destinations at both java and abap stack. Thus the gateway error is resolved.

Also in service file - sapmsNSP 3600/tcp

host file - ipaddress FQDN is maintained.

Both abap and java server are in different domains. I had SSO configured and is working well.

Now when i try to create a JCO, it is throwing me this error.

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=minisap GROUP=PUBLIC R3NAME=NSP MSSERV=sapmsNSP PCS=1 ERROR The message received isn't from a message server.
