I am trying to do some configuring on our OpenNMS monitoring software. I've noticed that the Foreign ID's are not updatable from the GUI once the node is created. Is there a way to update these or do I have to completely remove the Node and reinstall them?

I made a project with Spring Batch. However, due to the company's operating policy, foreign keys cannot be set in the meta table.
In this case, is it okay to make a table with only general columns and then insert data directly at the application level?
If there is another solution, please let me know.

How is your company planning to deal with data consistency without foreign keys? Your company's policies should really be reviewed.
The answer to your question is yes. You should be able to use Spring Batch without adding the foreign keys in its meta-data schema, but you obviously risk to have data inconsistencies and some undefined consequences in some cases.
I got a org.postgresql.util.PSQLException: ERROR: duplicate key value violates unique constraint after I quit and start my application via docker compose.
I am using a postgresql database while the business logic is implemented with Spring. For OR-Mapping I use Hibernate and the id is generated via #GeneratedValue(strategy = GenerationType.AUTO) which maps to sequence in postgresql. It seems like the sequence is regenerated after rebooting the application i.e. the SEQUENCE will start from 1 after restart i.e. when you add two entities to the database and restart the app the first two inserts will fail.
Any suggestions? I am stuck
Yesterday, I made some migrations to a website that I had to rollback. Luckily, I had a backup of the database, and was able to restore the lead database to a "good" state using Heroku's pg:backup:restore facility.
The lead database is followed by another database. Does the follower also get "restored" when I restore the lead? Will it contain the same data as the leader?
You can't rollback an existing database. When you use the rollback functionality you're actually forking the targeted database and thereby creating an entirely new database without any followers. If you need to do this operation for your primary database, you'll need to put the application maintenance mode before creating the rollback database, promote it to primary and then recreate the any followers.
after successfully upgrade to dynamics from 2016 8.1 to 9.0.5 on prem,
we encountered a problem with business process flow,
as we know each bpf has its own entity in the DB,
we use an OOB bpf in incident entity that called phonetocaseprocess,
the problem is that i saw after the upgrade that the newly table created for
that bpf - is empty :() , so all the current incidents failed on update because
i get an error that said that : phonetocaseprocess With Id = 196dc1e2-466f-e911-80e6-
00155dc4022d Does Not Exist.
when i create a new incident record it works fine and a record is created in
phonetocaseproccess table.
someone encountered that? or have an idea? thank you
UPDATE
we were able to resolve this by running the script provided in the above forum before the upgrade run, after this the upgrade was successfully completed.
https://community.dynamics.com/crm/f/microsoft-dynamics-crm-forum/232669/business-process-flow-instance-exists-error-after-crm-2016-upgrade/639024
The problem occurred because processes in the source environment did not have a unique name in the database, which resulted in the upgrade not converting the data to the correct table in the DB but to another table in new_bpf_guid format.
hope this will help someone
That's because your existing records are related to the older process and that the process in the newer version has different GUID. See the snapshot below:
To correct this, you have to migrate the process entity data with the existing primary keys in the older version.

You can read here how to use foreign keys in SQLite manager.
In short use line below when you create your table.
