Learn about the issues you may encounter when using Oracle Machine Learning and how to work around them.

• Deletion of Notebooks Loaded in Zeppelin Server
  
• Notebooks Update Slowly in Browser
  
• Notebooks of 1000 MB Size are not Saved
  
• Notebook Stops Responding while Running Paragraphs
  
• Number of Rows in Interpreter Results
  
• Permissions Button in Manage Workspace Should be Disabled for Admin Users
  
• Portability of Interpreter Bindings
  
• Users with Administrator Role Restricted from Creating and Running Notebooks
  

Notebooks that are loaded in the Zeppelin server, cannot be deleted. To delete the notebooks, they must be unloaded.

Notebooks containing a large number of paragraphs, get updated slowly in the browser.

Currently, notebooks that are over 1000 MB (1 GB) in size are not saved or updated in the repository.

If a notebook stops responding while running the paragraphs in it, then request your Oracle Machine Learning administrator to restart the Connection Group.

The number of rows in a notebook, SQL, and script interpreter results can be added from the Connection Groups interface. Although you can add any number of rows in a notebook, but adding too many rows may cause the notebook to fail.

The Permissions button in Manage Workspace should be disabled for the Admin user because the Admin cannot grant permission to any user to his workspace. Currently, the Permissions button is enabled for the Admin user.

Interpreter bindings are not portable across Pluggable Databases (PDBs). If you export and import notebooks within the same PDB, then the interpreter bindings are preserved. But if the notebooks are created in different PDBs, then the interpreter bindings are not preserved after import. You must manually set the interpreter bindings after importing the notebook from a different PDB.

The Oracle Machine Learning administrator is restricted from creating and running notebooks and jobs.
