Question on Source System

How did you resolve inactive Source systems when there are changes to IP addresses/server names?

Some sites may upgrade the R/3 h/ware (and usually don't tell the BW teams).The source RFC logical names will be the same but the actual underlying h/ware may have changed IP address or host/server names. How did

the BW teams recover (after all the cussing)?

Are there any proactive steps that can be done for seamless IP address changes

TQ

Kumar

    Hi Nantha,

    We always do this IP Change thing when we INIT our Data Sources. We practiced a <i>Minimized Downtime</i> procedure by producing a FLASH COPY of R/3 to another Server and connecting BW to it. (<i>Same Host Name but different I.P. Address</i>)

    Under Transaction <b>SM59</b>, maintain the new I.P. address of the Server with the same Host Name. But the catch here is you have to restart BW since base from our experience, BW still connects to the old I.P. Address (I think it has something to do with Buffers retained in memory).

    After you reboot, it should now work...

    Hmm, why the need to maintain IP addresses?

    We use DNS Aliases for our servers, as long as the DNS alias resolves to a valid hostname you NEVER need to maintain IP addresses on the BW SM59 connections.
