"connectivity libraries needed are not found" error in IBM Data Studio
You may need to point IBM Data Studio to the database drivers. They are usually installed with DB2 under /myDB2_InstallationDirectory/SQLLIB/java.

The drivers themselves tend to be


db2jcc.jar
db2jcc_license_cu.jar


There are other drivers in that folder as well, but these two tend to be the main ones for Java (which IBM Data Studio is based on).
