Problems with SLD / SAP Gateway

[Former Member]

Hi everybody,

I have NetWeaver '04 SR1 installation - J2EE engine only + DTR and CBS, patched to sp10 (NT/MaxDB platform). So, development platform only, without ABAP stack. I also setup SLD according to documentation. As I want to access BAPI's in our R/3 system landscape from WebDynpro application, I tried to install standalone SAP gateway on the same machine where J2EE is installed. After succesful installation of SAP gateway, my JC00 instance doesn't work anymore!

It looks like G00 overwrited startup parameters somewhere so JC00 is not starting any more. I see that NT service definition for SAPJ2E_00 is changed to point to 'START_G00_nw04test' in ..\sys\profile directory, and when I change it to START_JC00_nw04test in registry, nothing happens.

From architectural point, if I have R/3 4.6C on one system and standalone J2EE server with SLD on other, is it necessary to install standalone SAP Gateway, or I can use one installed at R/3 4.6C?

If I use the one installed on R/3, and in RZ70 enter input parameters from R/3 installation (host sap01pbf, service sapgw11), activate configuration and start data collection, I get following output with errors:

Execute program: SLDGWSRV

Used RFC destination: SLD_NUC

I hope I managed to describe problem(s) well, if you need and more info, I'm more that willing to provide it at ivan.belic(at)gbs-it.com

Thanx in advance!

Problem solved:

- you don't need to have extra Gateway installed - it's enough to have one at R/3 side, so, after little messing with windows registry, I removed Gateway instance and got back JC00.

SLD RFC communication wasn't so easy:

-you need extra inputs in C:\WINNT\system32\drivers\etc (on standalone J2EE host!),

sapgw11 3311/tcp # sapgw<sysno> 33<sysno>/tcp

sapmsDV2 3611/tcp # sapms<sysid> 36<sysno>/tcp

- you need PUBLIC logon group on R/3 server, so you have to create it (SMLG transaction).

That's it! After that Data Supplier Bridge Administration from SLD and RZ70 from R/3 works.

See ya,

Ivan
