（1）查询数据库管理器配置参数，查找到端口名
[test88:dsadm:/gpfsetl/etldata/lch] db2 get dbm cfg|grep SVCENAME
TCP/IP Service name (SVCENAME) = DB2_dsadm
SSL service name (SSL_SVCENAME) =端口名为DB2_dsadm
（2）去/etc/services配置文件中查找端口名对应的端口
[test88:dsadm:/gpfsetl/etldata/lch] cat /etc/services | grep DB2_dsadm
DB2_dsadm 60004/tcp
DB2_dsadm_1 60005/tcp
DB2_dsadm_2 60006/tcp
DB2_dsadm_END 60007/tcp60004就是数据库对应的端口
