IGS in Cluster Portal

Question

Hi Experts,
  We do have a Microsoft Cluster Portal(SAP EP7 SP 18), with two app servers, IGS is working in one of the application servers not on the other one, Do we need to do any configuration to make it run on the other App server, as well? If not, what happening if that app server is stop!!!
Thanks,

Hi,
Try this first:
For IGS 6.40 and earlier:
The IGS (igs.xml) configuration file controls the connection to R/3 (using an RFC). This file is automatically created when the IGS is being installed and it is located in the "conf" subdirectory of the IGS installation.
Entries that begin with "<LISTENERRFC" are situated in this file and can look like the following:
<LISTENERRFC programid="IGS.12345" gwhost="SAPmain"
gwservice="sapgw21" recontime="60"/>
Now, in order to be able to add another R/3 system, you must edit the file using a text editor and add another "LISTENERRFC" entry which has corresponding parameters for the new system.
For IGS 7.00:
To connect a further R/3 system, you need to add the parameter "igs/listener/rfc/<no>" to the profile, where you replace <no> with a sequence number. The value of this parameter is "<programid>, <gwhost>, <gwservice>, <recontime>". Replace the names in angled brackets ("<>") with the corresponding entries. An example entry would look like this:
igs/listener/rfc/2=IGS.12345,SAPmain,sapgw21,60
version-independent
Similarly, you must maintain the RFC destinations in transaction SM59 in the respective system.. Refer to note 454042 for more information.
Also refer to Note 553221 if you want to operate an IGS on several BW systems.
See if the settings are as above.
This is actually from the Note 555531 that Manu suggested.
