1.增加编目节点https://www.cndba.cn/hbhe0316/article/4769https://www.cndba.cn/hbhe0316/article/4769

[db2inst1@db01 ~]$ db2 catalog tcpip node node2 remote 192.168.2.123 server 50000
DB20000I  The CATALOG TCPIP NODE command completed successfully.
DB21056W  Directory changes may not be effective until the directory cache is
refreshed.

2.查看节点编目https://www.cndba.cn/hbhe0316/article/4769https://www.cndba.cn/hbhe0316/article/4769

[db2inst1@db01 ~]$ db2 list node directory
Node Directory
Number of entries in the directory = 1
Node 1 entry:
Node name                      = NODE2
Comment                        =
Directory entry type           = LOCAL
Protocol                       = TCPIP
Hostname                       = 192.168.2.123
Service name                   = 50000

3.数据库编目，as后面的别名不超过8个字符https://www.cndba.cn/hbhe0316/article/4769

[db2inst1@db01 ~]$ db2 catalog db testdb as testdb12 at node node2
DB20000I  The CATALOG DATABASE command completed successfully.
DB21056W  Directory changes may not be effective until the directory cache is
refreshed.

4.查看数据库

[db2inst1@db01 ~]$ db2 list db directory
System Database Directory
Number of entries in the directory = 3
Database 1 entry:
