tRFC and qRFC?

[Former Member]

what are tRFC and qRFC? what is the difference between them?

[Former Member]

tRFC -transactional RFC-------implemented in asynchronous processing (QOS is Exactly Once).

qRFC-queue RFC----implemented in asynch..processing with predefined order(QOS is Exactly Once Inorder)

sRFC---synchronous RFC --implemented in Synchronous communication(QOS is Best Effort)

hi sekhar,

I wanted to undersand use of different types of rfc in context of XI ?

do u mean to say if i am selecting QOS is Exactly Once , XI will put message in a tRFC .. similarly for other..

Could you explain a bit ?

Hi,

in case of XI you only use tRFC (<b>asynchronous</b> RFC)

or sRFC - <b>synchronous</b>

you cannot use qRFC in standard with XI

hi michal,

i was reading a blog 'Reprocessing failed xi message'' where the blogger had given three approach for resending failed xi message..

in one case, resending message from qRFC was discussed..

but you are saying that we don't use qRFC?

[MichalKrawczyk]

Hi,

Naveen in his blog mentions that qRFC is used <b>in XI</b>

(but it's in XI internally) not in R3-XI link

that's why I said you can only use tRFC and sRFC

the blog you mention relates to XI's internal processing which is

something completely different

actually i was trying to understand 'resending functionality of XI'

For achieving the functionality of 'automatic resending failed xi message ' I need to schedule a background jon for reseting the queue status of appropiate queue.

Question;
