(102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed

[former_member745782]

hello everybody,

i have a problem in all my receiver RFC comunication Channel (PI 7.1).

Every night we resart the R3 system where CC need to comunicate.

On the morning all Receiver RFC CC don't work and i have the follow error:

Receiver channel 'CC_SAP_RFC_LOOKUP' for party '', service 'BS_ECD'

Error can not instantiate RfcPool caused by:

com.sap.aii.adapter.rfc.RfcAdapterException: error initializing

RfcClientPool:com.sap.aii.adapter.rfc.core.repository.RfcRepositoryException: can not connect to

destination system due to: com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect

to SAP gateway failed

Connect_PM TYPE=A ASHOST=192.168.10.38 SYSNR=00 GWHOST=192.168.10.38 GWSERV=sapgw00 PCS=1

I need stop and start the CC.

I cannot propose to customer to stop and start CC every morning.

How can i solve this problem?

thanks

Alex

availability time planning is the first choice...

otherwise make it (channel start activity) as a policy and ask the person who is taking R/3 restart to do that activity subsequently. (managerial solution... isn't it?)

Hi,

As a workaround you can plan the availability of your RFC channels according to the downtime of R3 system.

The channels will be stopped and started automatically in this case. take a look here,

regarding the problem, did you see Q25 of this note
