Local RFC Connection error

[Former Member]

Hi Experts,

I facing a strange issue. when i generate RFC connection (conection type:3) with target host ( its own IP ) . then do the connection test ,
connection test is throwing an error with ERROR DETAILS: connection closed .

At OS level, i am able to ping my own IP , what could be possible reason??

My TMS configuration is also not working.

your platform(OS, DB)?

Is this a copy system or fresh installed one?

Hi,

Its ECC 6.0 , AIX 5.3 , oracle 10.2g

this is copy system .. but it was working after system copy.

Hi Deepak,

Did you executed SECSTORE -> system data changed. You should execute the "secstore" transaction and modify old rfc configuration, if the SID and inst# is different from the source system, after the system copy.

Best is to delete all RED entries via TCODE: secstore > F8 (Execute) > Entries on right side.

Hi Huseyin,

I hv deleted the same .bt same problem exist.

actually main problem is  "INTERNEL RFC NOT WORKING" .

When i check the internel RFC test, it display "connection closed",.

i am able trasport through OS level.

is their any solution regrading internel RFC?

Deepak,

Could you paste dev_rfc<x> and dev_rd into the message, after you execute the rfcping command at the os level on the application server.

Download and apply the latest kernel patch. You may be hit the bug, below;

Note 1539233 - SM59: Connection test 'no data received'

Hi,

Is your connection named NONE under "Internal Connections" work? If not, please attach the Technical Settings tab image

[Former Member]

Hi Huseyin,

Connection NONE doesnot work , still throws same error.

When a do the connectio test , it shows:

Could you execute SECSTORE -> System data changed and paste the screenshot here?

Could you check that TCP/3300 has been allocated by another application by using "netstat"?

Best regards,

[HuseyinBilgen]

CAn you also share the RFC trace created during this test?

First SM59 > (from menu) RFC > Delete Trace

Run the connection test

Then, SM59 > RFC > Display Trace

[nicholas_chang]

Hi,

Do you see abap dump "CALL_FUNCTION_SIGNON_INCOMPL" in ST22? If yes, perhaps you can follow notes Note 1532825 - Deleting SECSTORE entries during system export/system copy

Cheers,

Hi Orkun,

I hv checked . port 3300 is used by gwrd process only..

[Former Member]

Hi Huseyin,

please find the RFC trace.

Hi Nicholas,

No dumps in ST22, and sm21 also have no records related to RFC.

[Former Member]

Could you delete red items om SM59 referred in the SECSTORE and create a new test RFC connection. Additionally, check "gw/reg_no_conn_info" parameter value in the SAP profiles.

Best regards,

Orkun Gedik

[nicholas_chang]

Is your system UC or NUC? just wonder is the setting correct?

[Former Member]

Hi Nicholas ,

System is non-unicode . same setting reflects in RFC's

How did you fix this issue, even am facing the same error.

Hi,

I know this is an quite old post. Nevertheless I faced the same issue (connectin closed (no data)) with connection type 'T'. The solution was to change from unicode to non-unicode.

Best regards.

[Former Member]

Hi Deepak.

RFC connection (T-code sm 59)

RFC connection between SAP to SAP and non SAP system.

1)1st define the Logical Systems (T-caode SALE)

•      SID<CLNT>CLIENT NUMBER (DEVCLNT000).
•      execute ->SALE->basic settings -> Logical System.
•      define the logical system (<SID>CLNT000).
•      assign logical system to the client in (T-code SCC4).

2)RFC connection

•      execute SM59.
•      name of the RFC connection (to identify easily provide the name of the logical system ).
•      select connection tyep=' '(it's local =3).
•      description abut the connection .
•      technical settings ( Host name and instance number).
•      select the load balancing.(if more then one instance is configured then select "yes"-provide      details of Target system ,messg serverand group.if "NO"then provide target Host name         instance number.
•      ensure that (etc/host entries are maintained for the target system )
• specify the gateway host and gate services
• logon security .

Can you check if you can connect on your local machine on the gateway port? So telnet hostname 33NN.

Hi ,

I have checked ,, gateway port 3300 is open . at the same time ,, i have also checked gateway monitor  through SMGW , connection OK is displayed.

Deepak,

Have you changed the local IP of your SAP System? if YES, then reboot the server one time and it will work. I face the same issue when i have re-installed my PRD on different machine with different IP then everything was working except its not registering itself in TMS. So the problem was at my DEV server end because in memory of DEV Server it didn't refresh the new IP of PRD and was using the OLD IP. So, when i reboot my DEV then everything went perfect.

Thanks,

For TMS check permission for /usr/sap/trans directory
