进入：db2cmd命令行
//第一步：编目远程节点
//db2 uncatalog node itil
db2 uncatalog node itil
//itil:远程节点名
db2 catalog tcpip node itil remote 192.168.5.73 server 50000 remote_instance db2 system dpsvr
db2 catalog tcpip node tc remote 192.168.0.15 server 50008 remote_instance db2 system dpsvr
//第二步：编目数据库
//db2 uncatalog database dbcrea
//dbcrea:数据库实例名；tcdbcrea:本地数据库实例名(url下的jdbc:db2:inst2tc)
db2 catalog database dbcrea as tcdbcrea at node itil
db2 catalog database tradeCtr as inst2tc at node tc
//测试数据库连接
//db2 connect to tcdbcrea user user_name USING password
db2 connect to inst2tc user tc using business
