I started exploring knime today. I need to use same database credentials in multiple workflows. I would prefer defining credentials only once and re-using them elsewhere. How to do this?
Workflow variables cannot be used in other workflows. Is there a place for workflow group variables which can be accessed from any workflow?
Good one -- I guess writing them to a table would be an option, or maybe some commercial TeamSapce / Enterprise Server feature I'm unaware of?
Note that v2.9 has added local horsepower in this respect -- see "Enh 4690: Local Workspace supporting data files and meta node templates" in the changelog (http://tech.knime.org/changelog-v290).
Not yet entirely sure how this works, though - I wish I could replicate Rosaria's success story posted here: http://www.dataminingreporting.com/2/post/2014/01/knime-explorer-now-supports-data-as-well.html
EDIT: Navigating to the local folder (easy by right-clicking) and pasting source data there made it work, just dropping them onto the KNIME Explorer didn't in my private Win7-64 / K2.9.1 setup.
