For reason to change server IP address,

EP: 192.168.2.21 to 192.168.2.41

BW:192.168.2.22 to 192.168.2.42

and fix system by steps:

1,logon bw system,using tcode sm59 to modify tcp/ip connection.

2,logon ep system using visual administrator,and modified jco parameters.

3,logon ep system using ie,and modified sld,datasupplier.

4,restart bw and ep system.

after changed,the BEx Web did not work,

enter Maintain Jco destination

select jco destination: mete_data

click test

raise the error:

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=B MSHOST=bw GROUP=public R3NAME=BW1 MSSERV=sapmsBW1 PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR partner '192.168.2.22:sapgw00' not reached TIME Tue Dec 18 15:39:34 2007 RELEASE 700 COMPONENT NI (network interface) VERSION 38 RC -10 MODULE nibuf.cpp LINE 4601 DETAIL NiBufIConnect: connection pending after 60000ms SYSTEM CALL connect ERRNO 55 ERRNO TEXT A connect operation on a socket is not complete.

Hi,

It seems that the SAP gateway host is deactivated or the TCP/IP port 33xx (where xx corresponds to the system number) is not open.

First try pinging <IP address>. If there is no reply, then Boot SAP Gateway host required.

Check whether the TCP/IP port 33xx is open (where xx corresponds to the system number) and start the SAP gateway

The TCP/IP port is also partially defined in the services file as an sapgw<SID> or sapgwxx entry (where xx corresponds to the system number). The services file is in the Windows directory or in WinNT/System32/drivers/etc.

Hope this helps.

Regards
