I have a problem with my Firebird database. The primary key of one of the tables is referenced by another table that was actually dropped earlier. So this reference from a non-existent table was causing errors when I try to make any changes in the table data.
So I did a backup and restore and the bad reference was gone but now when I try to connect to my database more than once at the same time I get the following error:
database [file path] shutdown
How can I solve this?
