MDriven Server problem with evolve

Revision as of 08:44, 7 February 2023

NEW: From 2022-10-28, we now look for App_Data\MissingOrMapping.xml. If ORMapping is missing in the startup of the app and the file is found, we inject the file. The included file is version 13500 of the script. You can change it if needed.

Here is a short video discussing this: https://youtu.be/vwF1rjXjCak

Versions up till 2019-03-25 had issues with admin database evolve.

This gave the effect that upon evolving the admin database of MDrivenServer ( this happens when MDrivenServer has an updated internal model), the changescript needed for doing further evolves would get ERASED.

If this happens, the MDrivenServer will not be able to evolve to newer versions.

To restore this missing script, follow the instructions below:

Download this XML File:Evolve.xml and open it in a text editor, NOT a browser - you need to preserve the encoding of < and >.
1. Version 2022-05-13 onwards: File:OR-mapping_version_20220513.xml
2. Version 13500 (2021-10-12 - 2022-05-12) : File:OR-mapping_version_13500.xml
3. Version 10923 (2019-04-03 - 2021-10-12) forward: File:OR-mapping 10923 13499.xml
Go to your MDrivenServer-settings-admin
Check if you have the script already (Read the current Evolve script). If not, paste the correct script based on the version + then "Write Current Evolve Script" + Ensure you SUCCESSFULLY LOADED THE SCRIPT by ensuring that Read CURRENT EVOLVE SCRIPT RETURNS IT.
Try to make admin evolve once more.

Admin DB Issues Described

When admin DB refuses to work, it may be due to one of these issues:

Eco_Ormapping is empty AND the DB schema is old
Eco_Ormapping has the newest versions - but the DB schema is old
DB schema is new but Eco_OrMapping is empty

If issue 1: Evolve cannot run - and Repair only takes us to issue 2

If issue 2: Evolve does not discover the need to update db_schema and the admin will not start due to the old schema

If issue 3: No error is seen until a future evolve when you end up at issue 1

The correct state is: 4. Eco_Ormapping Describes the current Schema

To solve issues 1 & 2: Grab the correct script from those available above - write it with "Write current evolve script" followed by "Evolve admin DB"

To solve issue 3: do "Repair admin evolve script"
