Locked Diagrams in SAS Enterprise Miner
*** The following is from SAS
In regards to the locked diagram, the fastest way to delete the lock typically is to log into SAS OnDemand for Academics Control Center. When a diagram is opened for editing, a lock file is put in place to indicate the diagram is being used. Sometimes, the lock file will remain even when the user is finished editing the diagram. As a result, the user will get an error in a pop-up window stating that “this diagram is currently locked”. To correct this problem, you should close the diagram if it is open. Then open SAS Studio from the SAS OnDemand for Academics Control Center. Open the “Server Files and Folders” tab. The lock file will generally be in this path:
/home/(user name)/(project name)/Workspaces/EMWS1 (or similar)/System
****The “.lck” file I deleted was found at the following filepath in your Enterprise Miner project files in SAS Studio: /home/basquinsophonie0/Exam1/Workspaces/EMWS1/System
If your diagram locks up on you again, you can head to that file location and delete the “.lck” file, which should allow you to open the diagram.****
The lock file will have a name like “wsopen.lck”. (The lock file always has the extension “.lck”. )
You can remove this file to enable editing of the diagram.
