whats the best approach for load testing Web AS 6.20 ?

[Former Member]

Hi there,

has anyone of you any expierences with load and performance testing of Web AS 6.20? We want to run a combined BSP- and SAPGui loadtest. While testing the BSPs can be covered pretty well with the tool we usually use for loadtesting (Segue Silkperformer), the SAPGui testing cant. I know theres a tool called Mercury LoadRunner which can perform loadtests of SAP transaktions but its kinda expensive and therefore not an option at the moment. further SAPs eCATT doesnt seem to be capable of doing loadtests. any ideas?

kind regards,

Christian

Hi Christian,

you can use the same interface eCATT and Mercury are using to control SAP GUI.

On this base you have to implement what you need in terms of control flow (some script logic ... ).

On the other hand you have to find a way to generate multiple user sessions each running one SAP GUI.

We did some of such projects allready using a mix of SAP and Windows tools and own build apps.

Come back to me if you are interested (jens.fichtner@devlogix.de).

yes. im aware of the opportunity of controlling the sap gui via a COM based scripting interface. we already implemented a solution based on this sap gui scripting engine which is able to control several sap guis on the same machine with multiple users (and on multiple machines of course ).

but if you want to run loadtests with thousands of virtual users you get a massive overhead because of all the sap gui instances

eCATTs approach for runnig loadtests on the other hand doesnt fit our demands of running load and performancetests in a distributed environment (along with some other issues) ....

can you give me some details on your experiences with sap loadtests (how many users, how many "loadproducing machines",...)

best regards,
