Many dev_jrfc*.trc files written under server0 node

[Former Member]

Hello Experts,

We are on 7.02 SP11 ECC - Only Java Stack (ABAP and Java split)

We are filled up with dev_jrfc*.trc (under cluster/server0 node) files writing below message:

--------------------------------------------------------------------------------------------------------------------------------------------------------------------

Error> occured  >Thu Nov 27 18:39:49,135<
>RfcIoException:
    message: CPIC-CALL: SAP_CMACCPTP3 on convId: 00000000

I had a look at Note - 917117 - Error CPIC-CALL: SAP_CMACCPTP3 in dev_jrfc.trc describing the exact message

However, that Note seem to be not applicable for our verison

In the above error message, <hostname> is a ABAP different ABAP stack/.

From this ABAP stack, I can see the connection to this Java stack in SMGW of Logged on Clients.

I am confused how come this ABAP stack speaking to the Java stack by Jco connections - I couldnt find any RFC connection to the Java stack

Can someone guide me the reason for this RFC connection and also how can we restrict this?

Thanks,

Subbu

Hi,

registration of tp WEBDYNPRO_<SID> from host

            <HostName> not allowed

this error message clear indicates, that  the problem is, that from the  <HostName>, where you want to reach a gateway, the registartion is not allowed. It is because the reg_info file setting on that gateway.

gw/acl_mode=0 is a workaround, that disables the gateway security, in that case all program, even unwnated programs can register on the gateway.

Rather extend the rules in reg_info file accordingly.

Afterwards reread teh reginfo file:

smgw->Goto->Expert function-> External security->reread

Maybe useful:

Hello Subbu,

Please check this KBA 1974723.

Also check if you have activated the jcorfctrace parameter for any of the JCos in the system.

Start Visual Admin and navigate to Server - Services - JCo RFC Provider

Check the Program ID of all the RFC's available there.

If possible supply the RFC details.
