Error running DB2MOVE command
In order to get the DB2 command window (DB2 CLP) in Windows, you can either Windows key + R and type db2cmd or Start > All Programs > IBM DB2 DB2COPY1 > DB2 Command Line Processor and then you can execute different db2 commands, like.

db2ilist    --> List instances
db2level    --> DB2 Version
db2licm -A  --> DB2 License

etc.
