Close JCO Session

Dear All,

We are facing a major performance problem in the production environment. We have more than 300 users in the production. when I was checking JCO connections status through sm04 transaction, we see most of the connections stay open more than one day. After reaching the maximum, we are forced to restart the server. Then only the JCO connections are closed. We have SSO enabled for all the model data JCO connections.

I found some peoplo adjust do it like this:

-

Zzcsh_Nbzy_T09_Input input = new Zzcsh_Nbzy_T09_Input();

input.setI_Bukrs(el.getI_bukrs());

input.setI_Date_B(el.getI_date_b());

input.setI_Date_E(el.getI_date_e());

input.setI_Only_Sbd(el.getI_only_sbd());

input.setI_Swerk(el.getI_swerk());

try{

input.execute();

}catch(Exception e) {

reporter.error("error："+e.getMessage());

}

wdContext.nodeZcsh_Struc_Sbbd();

Common.getReturn(input.getOutput().getReturn(),reporter);

List list = input.getOutput().getTb_List();

wdContext.nodeZcsh_Struc_Sbbd().bind(list);

input.modelInstance().disconnectIfAlive();

-

I met this error:

-

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: connection closed without message (CM_NO_DATA_RECEIVED)

-

How can I do it?

Best Regards.
