ITS 620 reconfiguration

[Former Member]

Hello every one.

We are in process of Migrating from 32 bit hardware to 64 bit for our 4.7 enterprise system on sql 2005. After hardware migration we will upgrade to ECC6.

I need to reconfigure ITS (external) for 2 weeks before upgrade to ECC6 to communicate to R/3 backend. I am not sure what is involved and where to start.

Can you please direct me to any oss notes or technical papers which deals with ITS migration to new hardware. (Backend R/3 is migrating to new hardware not ITS Agate and Wgate).

Any help is appriciated.

Regards

KG

Hello KG,

I'm not sure if I got the question right, but if only the R/3 is changing then there isn't too much to do on the ITS. The Standalone (External) ITS does not care if the R/3 system is a 32 bit or 64 bit machine. If you want to use the existing ITS instance to connect to the new R/3 system on the 64 bit machine then you only need to change the global.srvc file to direct it to the correct app server or message server. You will change service parameters like ~appserver ~systemnumber ~systemname ~messageserver ~logingroup, etc.

If you want to keep your existing ITS instance then you will just need to install a new ITS instance to connect to your 64 bit R/3 system.

Once you upgrade to ECC60 though the SAP Basis should be 7.00. From 6.40 we have the Integrated ITS available and you will have to use it with Basis 7.00 or higher (note 709038). You should then search SDN messages for migrating from external ITS to Integrated ITS.

Edgar,

Do I need to republish the services after I change the global.srvc file?

Hello KG,

That's a good point...I'm not sure what applications/transactions you're using though. If you're just using the webgui service then no, you don't need to republish. If you're using applications with IAC (templates and mimes) then it is a good idea to publish again.

Please note that after going to ECC 60 you will not have a global.srvc file anymore...you'll have to use the Integrated ITS.
