I am assuming that requestor will be Db2 Client for JDBC and ODBC - and server is Db2 z/OS.
For JDBC try to put in a classpath jar file db2jcc_license_cisuz.jar and try again. This file should be available on m/f from where you have activation package for Db2 LUW or somewhere else :-)
For ODBC - assuming you catalogued remote database - you will need db2consv_ee.lic license file; it should be available on m/f as well ...
