Installing SQL Workbench/J
Installation is a bit of a pain.
How to install:
- Download the SQL Workbench/J zip and manually extract it to something like
C:\Program Files (x86)\SQLWorkbench-J (no spaces!)
- If it's not installed yet, download and install the Java SE Development Kit (JDK)
- After installation, the JDK should be found in a folder named something like
C:\Program Files\Java\jdk-24\
- (I tried installing the JRE, but that wasn't sufficient for some reason)
- Use these instructions to change the system-wide environment variables.
- Set JAVA_HOME to be the path mentioned above, eg.
C:\Program Files\Java\jdk-24\
- Double-click
SQLWorkbench64.exe to start it.
- You'll probably want to "Pin to Start" on that .exe also.
downloading JDBC drivers
(the official documentation is here)
These should be extracted and placed into the subfolder C:\Program Files (x86)\SQLWorkbench-J\JDBC Drivers\.
- DB2 driver ("db2jcc4.jar")
