安装了informix服务器，
在服务端连接正常。
在另外的装了客户端的机器上却连接不上？
PB连接时报错信息：
SQL error -931 : Cannot locate svc_pfbank service/tcp service in /etc/services,ISAM error 11004:Unknown error message 11004
有高手知道是怎回事？？
------解决方案--------------------------------------------------------
Cannot locate servicename service/tcp service in /etc/services.
The service servicename is not listed in the network configuration file /etc/services (UNIX) or (DOS). Check the $INFORMIXDIR/etc/sqlhosts file, and check that the service name for the desired server is correct. If so, contact your network administrator to find out why the service is not known. If you are using IBM Informix OnLine for NetWare, check the file on the client for the required entries.
