I see the same issue here. Batch or interactive.
The SQLRPGLE programs have EXEC SQL CLOSE at the end of the need for the SQL run. I also added EXEC SQL RELEASE ALL

The file stay open until the job ends. For batch jobs, no issue. But for some of the interactives, that's a problem when the user is sitting on the menu with nothing running. They think they are out of the job, but the file is still open.

Right. This is normal behaviour.

I've had to tell myself over and over: 'SQL is not RPG with a funny
accent.' SQL is a different thing altogether. In RPG, when we CLOSE a
file, it is closed. Done. All references gone. In SQL, when we CLOSE
CURSOR, Db2 might keep that cursor around so that the database engine
can reuse it if it's needed soon. This is called pseudo-close, and it's
a pretty handy part of the Db2 performance strategy.

On 7.3, I can't remember having to do anything special to deal with
pseudo-closed files. IBM i seems to do a full close when needed. In the
past, I did have a couple of issues; mainly with SAVOBJ and CPYF *REPLACE.
