本文介绍了如何确定DB2数据库的TCP/IP连接端口，默认情况下该端口为50000。通过命令行工具和系统配置文件可以验证实际使用的端口号。文中还提供了在Linux环境下查找DB2监听端口的具体步骤。

db2安装完成后，tcp/ip连接端口默认为50000，可通过下面的方法确认：

1、使用命令 db2 get dbm cfg |find "SVCENAME" 查找到TCP/IP 服务名

2、到系统配置文件里找到service name 对应的 port number
windows：查看 c:\windows\system32\drivers\etc\services

aix：查看 /etc/services

如下：

DB2_DB2              60000/tcp
DB2_DB2_1          60001/tcp
DB2_DB2_2          60002/tcp
DB2_DB2_END      60003/tcp

db2c_DB2 50000/tcp

3、使用 netstat -an 命令查找tcp/ip 服务的端口

4、另外附上一个关于linux系统下的查找方法（摘抄帖子）：

In JDBC configurations for WPA, you have to specify the port that DB2 is listening on. I usually look for /etc/services or try one of 50000/50001 and it usually works. In SUSE Linux, both the solutions did not work and there was another process (Multithreaded routing toolkit aka mrt) was listening on port 50000.

So how do we find out the DB2 port in a reliable way? Read on...
Step 1: Set the DB2 environment.
$ . ~db2inst1/sqllib/db2profile

Step 2: Find the service name for DB2 instance. It basically involves running "db2 get dbm cfg" command and finding a line containing SVCENAME.
$ svc=`db2 get dbm cfg | grep SVCENAME | cut -d= -f2 | awk '{print $1}'`

Step 3: Find the service name that you got from Step 2 in /etc/services or %SYSTEMROOT%\system32\drivers\etc\services. That is the port DB2 is listening on. $ grep $svc /etc/services

Hope you find this useful.
