Problem while calling RFC

former_member396896 — Thu, 08 Jan 2009 07:07:54 GMT

Hello Experts,

The problem is when i call RFC from an adapter system once, then it executes properly and returns data. But when i am calling the same function module at faster rate ( calling it 50 times in a minute, this includes opening up connection and invoking RFC and closing up connection without waiting for its response or data ) - Stress Testing. It works fine till 40th call but then on it goes into queue..n throws error like "timeout during allocate of registered prog".

And could u tell me the T-code as whr to monitor the RFC status.

Any Help.

Hi,

just two suggestions.

Try to put a "wait up to <x> seconds" (one second should be enough) from one call and another. It surely will during more but this should solve your problem.

To trace the RFC, use the ST05 transaction and select "RFC trace".

Bye

Andrea

thnx Andrea for the reply.

Just a small mistake in the post. its like 50 calls in one second ( Not in one minute ).

Every system has max rfc connections at a time defined at OS level, cannot exceed it.
