Former Member — Mon, 22 May 2006 10:46:08 GMT

Hi.

We developed RFC Java iView for SAP R/3.

This iview connect SAP R/3 and call RFC FM in SAP R/3.

We got connection error during high load.

Error is

"max no of 100 conversations exceeded".

So, I checked SAPFactory properties using Visual Admin but I think we got enough conenction.

Here is parameter.

Expiration : Checked

Connection Lifetime : 2

Maximum Connections : 1000

Cleanup Thread : 10

Maximum Time to wait for connection : 4

JEE System has below error :

#1.5#000F203CC23C002000007C33000050550004145E2C7DAE0A#1148294628636#/System/Server#sap.com/irj#com.sap.portal.connectors.R3#rtst018#54224##hhie01_E01_4224450#rtst018#d888e6e0e97f11da9210000f203cc23c#SAPEngine_Application_Thread[impl:3]_7##0#0#Error#1#com.sap.portal.connectors.R3#Plain###(R3/BW) Failed to get connection.

You will have to set the following environment variable

set CPIC_MAX_CONV=500 and restart your Portal.

If you are using Windows. Then you can right click on the properties of My Computer and select properties. Go to advanced Tab-->Environment Variables and then add this CPIC_MAX_CONV paramter. Restart portal after this.

Thanks everyone.

Our portal runs in HP Unix.

I'll going to change ".sapenv_<hostname>.csh" file.

Am I correct ?

Regards, Arnold.

Hi Arnold

u can set by following

By setting the environment variables CPIC_MAX_CONV the library can manage more parallel connections.

Windows : set CPIC_MAX_CONV=

Unix : setenv CPIC_MAX_CONV ( csh )

Unix : export CPIC_MAX_CONV= ( ksh )

Thanks again everyone.

I found "Maximum Connections" properties for SAPFactory in Connect Service.

Is there any difference with "CPIC_MAX_CONV" ?

Please explain difference with "Maximum Connections" and "CPIC_MAX_CONV".

Regards, Arnold.

Re: URGENT : "max no of 100 conversations exceeded".

Former Member — Mon, 22 May 2006 12:05:42 GMT

Yes, they are different.

CPIC_MAX_CONV variable defines the maximum number of CPI-C connections which the CPI-C API can administer.

Maximum connection is for the SAP Engine I guess. Not sure though.

Hi Arnold

When The external RFC/CPIC server cannot open any additioanl connections than u get

"ERROR max no of 100 conversations exceeded"

By setting the environment variables CPIC_MAX_CONV the library can manage more parallel connections

If an RFC server program registers with, for example, 100 threads at the R/3 gateway, 100 connections are initially kept in the server program. Every RFC running on this type of connection creates an additional entry in the connection list of the RFC server program. This means that, under full load, a maximum of 200 entries are possible.

I have not sure idea about "Maximum Connections" properties for SAPFactory in Connect Service

can any one tell me how to find CPIC_MAX_CONV value in ITS admin. please tell me the path where I can find this value.

Re: URGENT : "max no of 100 conversations exceeded".

Former Member — Tue, 14 Aug 2007 13:53:09 GMT

We did change ( rather added ) this CPIC_MAX_CONV to 200 for ITS ( 100 is default as per the note) and it is done in the Environment variables in windows.

Thanks
