Load balanced rfcs issue

74 Views Last edit Jun 06, 2018 at 10:35 AM 2 rev

Hello,

We have a rather strange situation. We have migrated to new servers using SWPM System Copy tool and all has been OK apart from the fact that now any load balanced RFCs from our ECC system to other servers don't seem to work properly.

If I test a load balanced RFC to our BW system for example in SM59, the authorisation test works fine. However if we run an extractor from BW it errors saying it's lost connection, if I set that RFC to a direct connection to the CI directly it works absolutely fine.

I realised this morning that this situation is also true of another load balanced RFC we use with Data Sync Manager, an EPIUSE product. Things were failing and I changed the load balanced RFC to a direct connection and it worked fine....

Can anyone think why load balanced connections wouldn't be working properly ?

I have made sure all ports are open both ways on server firewalls etc. Have also tried ticking and unticking Ext. RFC-enabled in SMLG in the target system and this seems to make no difference.

Any thoughts would be appreciated!
