I am planning to do SQL replication through InfoSphere Federation Server and installed the latest version from IBM website, while running the executable iisetup.exe, federation tool create the db2 instances and ask for db2user password and port as well, I have given all the required information and at the end installation and JDBC wrapper was successfully completed. after that I have open the db2 command prompt through administration. I am getting issue in running all the command eg
C:\db2\BIN>db2start
SQL1390C The environment variable DB2INSTANCE is not defined or is invalid.
C:\db2\BIN>db2 GET DATABASE MANAGER CONFIGURATION
DB21018E A system error occurred. The command line processor could not continue processing.
