Mapping Runtime Error

[Former Member]

Hello,

We tried executing a scenario HTTP --> RFC with 25 virtual users simultaneously.

But I got following Error:

<SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

  <SAP:Category>XIServer</SAP:Category>

  <SAP:Code area="MAPPING">JCO_COMMUNICATION_FAILURE</SAP:Code>

  <SAP:P1>Error when opening an RFC connection</SAP:P1>

  <SAP:P2 />

  <SAP:P3 />

  <SAP:P4 />

  <SAP:AdditionalText />

  <SAP:ApplicationFaultMessage namespace="" />

  <SAP:Stack>&quot;COMMUNICATION FAILURE&quot; during JCo call. Error when opening an RFC connection</SAP:Stack>

  <SAP:Retry>N</SAP:Retry>

  </SAP:Error>

Can I increase the number of parallel processes in VisualAdmin>JCO RFC Provider>AI_RUNTIME_ to 300?

Or is there any other solution?

Please help to resolve this.

Thanks in advance.

Beena.

Try this

/people/prashanth.azharuddin/blog/2006/11/24/some-errors-in-an-xi-production-environment

U may also check the application sap.com/com.sap.xi.services in the J2EE Engine

Hi Beena,

i assume, that's a typical memory bottleneck error. You have to do just the opposite: Reduce the number of parallel processes.

Plz have a look to <a href="https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_bc_xi/~form/handler">Note 862405</a>

Hi,

We could address the issue by tuning the parameter CPIC_MAX_CONV.

Now I dont get this error.

Thanks for replies.

Hi Beena,

Could you please tell us where to set this parameter to avoid such type of errors in detail.

Your early response is highly appreciated.

Many thanks in advance.
