RFC_GET_FUNCTION_INTERFACE very slow

[Former Member]

Hi anyone,

We have problem with performace on portal when it makes a call on r/3 using JCO and JRFC to execute a RFC.

Scene: The problem occurs when the RFC is generated from portal

application via JCO.

The minimum execution time is 6 seconds. Two seconds to call JCO, three

seconds and half to execute RFC_GET_FUNCTION_INTERFACE (standard) and

DDIF and just 0,5 seconds to execute of the ZRFC that extract the data

on R/3.

In fact, we need to lower the time to execute

RFC_GET_FUNCTION_INTERFACE standard and DDIF.

There is no SAP Note or documents on SDN to fix this!

Any suggestion?

Thanks

Best Regards

Hi

Ricardo,

Where you able to resolve the issue with "RFC_GET_FUNCTION_INTERFACE" and DDIF getting called every time a BAPI is called from the portal using JCO ??

I am also experiencing the same issue using JCA which is probably using JCO internally !!

Thanks

Ricardo,

Is this a first-time-only performance penalty, or it is associated with every call? In second case, probably you are not caching metadata...

Check out the execution path of the SQL behind the RFC.

Have you added a client index that is slowing this down?

Have you dropped an index ?

You need as well to determine which component is causing the delay:

a) network / connection / SSO ticket ?

b) RFC itself (see above)

Enjoy
