Error occurs while making multi JCo(3.0.5) clients stressing test

[Former Member]

Hi JCo Expert,

I ran into an error while doing JCo standalone clients stressing testing.

I have one single ABAP server(SAP NetWeaver 7.1 Dual stack installed) and try to have 180 JCo clients concurrently access it for the same RFC.

In client side code, one single JCoDestination instance will be shared by all the threads to make the call with stateless style.

I noticed that in the same condition, only when my thread number is more than 90, the above error occured. Other number less than 90 would be fine. Here is my jcoDestination configuration file content:

jco.client.lang=en

jco.destination.peak_limit=10

jco.client.client=001

jco.client.passwd=abc

jco.client.user=abc

jco.client.sysnr=00

jco.destination.pool_capacity=200

jco.client.ashost=abc

Did I get something wrong in my client JCo code or I need to tune my ABAP server. My target is to have 180 concurrent clients to be running more than 30 mins.

Thanks,

Jian
