Unable to connect to JDBC data source Issue When trying to test load 20 records from the data source, the error below is seen- MID Server reported error: java.sql.SQLException: com.ibm.db2.jcc.am.SqlSyntaxErrorException: [jcc][t4][10509][13454][4.21.29] Connection to the data server failed. The IBM Data Server for JDBC and SQLJ license was invalid or was not activated for the DB2 for z/OS subsystem. If you are connecting directly to the data server and using DB2 Connect Unlimited Edition for System z, perform the activation step by running the activation program in the license activation kit. If you are using any other edition of DB2 Connect, obtain the license file, db2jcc_license_cisuz.jar, from the license activation kit, and follow the installation directions to include the license file in the class path.
