Charm - Domain Link connections

I have a very puzzling problem trying to setup Charm.

1st the SolMan is setup on a release 701 system while the Satellite systems (R/3 4.7) are on 620.

The original system's transport landscape is Dev - QA - Prd + Trn. There are 3 sandboxes (with a copy from Prd) on VMWare systems.

I'm trying to setup Charm and am having difficulty creating a Domain link between The SolMan and The Dev system.

I'm trying to create it from the SolMan system going to the Dev system. It appears to hang (on the SolMan system), eventually (5 - 6 minutes) giving an error "RFC system error in system/destination TMSADM DEV.EXTCOM, connection to partner 'server:sapgw00' broken / CPIC-CALL ThSAPCMRCV: cmRc=20 thRc=223#CPIC pr

But looking at the STMS from the Dev system, the SolMan does show up. With a blue arrow (waiting for domain link) status. After clicking on the Approve button, It appears to hang then comes withthe same error, but it appears to look normal.

The Link never does show up in the SolMan STMS landscape.

At first I thought it might be the TMSADM automatic password problem. (Capitals vrs lower case) but tested this against one of the Sandbox systems.

So I can create a Domain link from the SolMan (701) to a Sandbox (620) and everything works fine. I can also create a Domain link between the Dev system (620) and the same Sandbox (620) system. But can not create the Domain link between Dev and SolMan.

In the SolMan dev_rd trace record I found the message:

***Log QOI = NiIRead: recv (10053: WSAECONNABORTED: Software caused connection abort)

  • Error = NiIRead: SiRecv failed for hdl 31 / sock 769 (SI_ECONN_BROKEN/10053: ...

Error connection to partner 'hostname:sapgw00' broken

errno 10053

errorno text WSAECONNABORTED: Software caused connection abort

Anyone have any ideas of what I need to do to overcome this error?

I have even turned off the anti virus on both systems, just to check and get the same results.

    Hi Ken,

    Its really seems to be confusing but i am sure something is messy.

    You can go like this way:

    1) Check host name of each other(solman.dev) is maintained on both the systems.

    2) Create a manual RFC from solman to dev and dev to solman test it!

    3) In case 1 and 2 is successful , delete TMS RFcs and create same manually provide your user name and password (Both way you need to create solman to dev and dev to solman)

    Revert after applying following these steps.

    • FYI, Yes, I believe we've fixed the problem.

      The Network team had enabled JumboFrame to a higher MTU than 1500.

      They reset it to the default 1500 and flushed the DNS cache. Then we were able to create the Domain link.

      The 3rd system that both Solman and Dev could establish the link to did NOT have this feature enabled. But both Solman and Dev did.

      We believe this caused our problem.

    • Hi Sajin

      My first guess is Password. Is the TMS system working fine before you tried tying in the SolMan? I seem to remember a problem with older kernels and that the passwords had to be capitalized. But if you had the TMS working before this, it's probably OK.

      Next I'd try firewalls. Does there happen to be a firewall blocking communication?

      I would also check the services file to make sure the dispatcher, gateway and message ports are open both ways.

      Without more information I can't think of anything else right off.
