Clearing a user's BLOB settings cache

Overview

Clearing the BLOB settings cache forces Impact CAD to delete the locally cached user settings for a specific database connection and reload them from the copies stored as BLOBs in the Impact database.

This is typically used as a troubleshooting step when support suspects the workstation’s cached settings for a connection may be corrupted, or after a setting has been fixed in the database and you want to ensure the workstation reloads a clean copy.

Prerequisites

• You must be able to open the Connect dialog in Impact CAD.
• You must know which Database: connection you are connecting to.

Steps

1. In Impact CAD, open the Connect dialog.
2. In the Database: list, select the database connection you want to connect to.
3. Hold down Ctrl + Shift on your keyboard.
4. While still holding Ctrl + Shift, click Connect.
5. When prompted “Are you sure you want to clear the BLOB settings cache?”, click:
   • Yes to clear the cache and continue connecting, or
   • No to connect without clearing the cache.

Result

• If you clicked Yes, Impact CAD clears (deletes) the local BLOB settings cache for the selected Database connection only on this workstation.
• Impact CAD then streams the settings again from the database and continues the connection.
• No backup is required as part of this step.
