db2查看修改端口號

db2安裝完成後，tcp/ip連接端口默認爲50000，可通過下面的方法確認：
      
     1、使用命令 db2 get dbm cfg
     找到"SVCENAME" 查找到TCP/IP 服務名
      2、到系統配置文件裏找到service name 對應的 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 服務的端口
      
     4、修改端口號
        直接修改services文件中當前服務名對應的端口號
     如：db2c_DB2 50000/tcp
     然後重啓數據庫即OK  db2stop  db2start
      5、另外附上一個關於linux系統下的查找方法（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 SUSELinux, 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.
