Error while testing JCO connections

[Former Member]

Hi,

Can anyone please help me with the following error.I am getting this when I'm testing my JCO connection :

RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=A ASHOST=cgnsap13 SYSNR=01 GWHOST=cgnsap13 GWSERV=sapgw01 PCS=1 LOCATION SAP-Gateway on host cgnsap13 / sapgw01 ERROR max no of cpic clients exceeded (300)

Thanks and regards,

Hi Bharathwaj,

I'm setting the connection timeout parameter as 0 for both my JCO dectinations, and this might be a better way as compared to closing connections.

Dear Lisha,

I am not able to get the relation between timeout and JCo s connections closing.. So would not be in a position to evaluate the same..

It would be nice if you could share with us ,

where we can set the max connections ...?any file...?

thanks and Regards

Hi Bharathwaj,

Please check SAP note 314530.

Also do check the Resource Management section in the link given below :

Hope that helps

Hi,

All the message server settings have already been done correctly.

The applications were running fine.The error i got was because the no. of cpic clients handled by SAP gateway exceeded the limit which was set as 300(default value).

On increasing the no. of connections by setting the gateway parameter gw/max_sys to the required value, the error gets resolved.

Thanks everybody,

Dear Lisha,

300 connections should be sufficient.. There should not be a need to increase it..

Are all the connections closed after usage ?

Hi

Please ensure that you have the msgserver entry in your services file. The problem you are getting is because of the message server. you need to have a entry like

sapms<System ID> tcp/3601

Also go to your SAP logon pad and check for groups. and type the sid in the box along with the appserver and then click on generate list. You should get some logon groups. If not you can be sure that your message server is not configured properly. Talk to your SAP Basis person

I think the problem is not with your JCo connection but with the gateway server.

Hi,

I tried giving a pool size of 100, the max perissible value, still the error persists.

Hi Lisha,

What is the Connection Pool Size for your JCO Connection?

Increase it and try again.
