Hi all,

just a easy question:
What could the reason be that my OSP publish failed, because of an ALTER TABLE.

I'm just inserting a new column into a existing table. Yes it's a key to another table, but not mandatory.

Beste Regards,


Ideally it should not an issue of adding a new column.For better understanding, pls share your oml or attach the exact error screenshot.

Hello Jeroen,

Did you change any data type of a field?

Please see this documentation link that can help you understand why you got that error:





We found the problem.

In the generated sql scripts to update the database Outsystems Runtime did insert a row in a table.
After that the table kept locked and another ALTER TABLE statement got a time-out.
We restarted the Outsystems Runtime Service and the problem was solved.
