1. Right click My Computer on ur desktop -> Propertie -> advanced -> Environment Variable

2. U should change the maximum number of connections in JCO destinations

Check SAP Note 314530 with content

<i>Symptom

The external RFC/CPIC server cannot open any additioanl connections.The following error message is displayed :

LOCATION CPIC (TCP/IP) on local host

ERROR max no of 100 conversations exceeded

Other terms

RFCLIB CPIC CPIC_MAX_CONV

Reason and Prerequisites

The number of parallel connections that can be held in the library is set to 100.

Solution

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 )

iSeries : ADDENVVAR ENVVAR(CPIC_MAX_CONV) VALUE(500) (for 500 connection .)

Special feature of the CPIC/RFC server program:

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. The value of the environment variable should be adjusted correspondingly.

hi,

Check ur Envirnment Varaibles, there u will find CPIC_MAX_CONV variable.

By default its value is set as 100. Increase it to 200.

In case this variable is not existing. Just create a new variable and assign it value 200.

Afterwords restart ur system.

Hi,

Check note # 821026:

...

The default amount of possible external JCO clients is 100. If the dev_jrfc.trc file in the server directory shows the error "ERROR max no of 100 conversations exceeded" the environment variable CPIC_MAX_CONV must be increased. Also refer to note 314530.

....

Kind regards,

Koen
