Corrupt MDriven Server

We have seen cases where the admin db __MDrivenServer/App_data/DatabaseCompact.sdf has been corrupted between deploys and will not evolve correctly.

Because of this scenario, a tool exists to help move the admin_ECO_ORMAPPING from a similar/same versioned DB into the corrupt one.

  1. Download the DB.
  2. Use the tool found here: C:\CapableObjectsWush\source\AppCompleteGeneric\AppCompleteGenericFixCorruptAdminDB\

What the tool does is:

  1. Given two compact DBs, read ECO_ORMAPPING into TextBox
  2. Allow to read ECO_ORMAPPING from TextBox into db2

How to use:

  1. Download DB
  2. Find same version DB
  3. Read ECO_ORMAPPING from correct - possibly manually.
  4. Update if no correct version is found and apply mapping to corrupt DB.
