安装DB2（V9.1）
To work around this issue, follow these steps:
Run the following DB2
command from the DB2 command prompt window:
db2 get dbm cfg
You will
see the following output:
TCP/IP Service name (SVCENAME) =
db2c_DB2
Change the port number. Run the following DB2 commands from the DB2
command prompt window:
db2 update dbm cfg using SVCENAME 50000
db2stop
db2start
Run the following DB2 command again to verify that
the service port is correct:
db2 get dbm cfg
This command should
return the following output:
TCP/IP Service name (SVCENAME) =
50000
Run the IBM? Tivoli? Storage Productivity Center installation program
again.
只要显示为 TCP/IP Service name (SVCENAME) = 50000就可以
