从 DB2 客户机编目 TCP/IP 节点
在已经安装DB2客户端的机器上添加server编目：语法
db2 => catalog tcpip node node_name remote hostname|ip_addressserver service_name|port_number
然后添加上面的database：
CATALOG DATABASE database-name
测试：
--catalog node$ db2 "catalog tcpip node tower06 remote 172.21.21.21 server 50000"--catalog database，后来补充$ db2 catalog db sample at node LOCAL1DB20000IThe CATALOG DATABASE command completed successfully.DB21056WDirectory changes may not be effective until the directory cache is refreshed.
注意使用username：
$ db2 connect to bitest user etl Enter current password for etl: Database Connection Information Database server = DB2/AIX64 8.2.3 SQL authorization ID = ETL----------已经变更 Local database alias = BITEST
其实在服务器端还需要做如下设置：
--检查/etc/services# cat /etc/services |grep -i db2ibm-db2 523/tcp # IBM-DB2ibm-db2 523/udp # IBM-DB2questdb2-lnchr5677/tcp # Quest Central DB2 Launchrquestdb2-lnchr5677/udp # Quest Central DB2 Launchrdb2inst1 50000/tcpdb2c_db2inst2 50001/tcp #DB2 connection service port db2inst3 50003/tcp--检查DB2COMM$ db2set -all DB2PROCESSORS=0,1 DB2COMM=TCPIP,NETBIOS DB2AUTOSTART=YES DB2SYSTEM=localhost.localdomain DB2INSTDEF=db2inst1 DB2ADMINSERVER=db2das1--检查SVCENAME$ db2 get dbm cfg |grep -i svc TCP/IP Service name (SVCENAME) = 50000
这样，客户端才可以连上
