Now THIS is interesting:
I just went into one of our demonstration files using Squirrel SQL. I
then did a WRKOBJLCK on the file, from a terminal session, and found no
locks whatsoever on the file or the member, even though Squirrel was
displaying the entire file.
Then I right-clicked on the file in Squirrel, and selected "Make Editable."
At that point, a SHRRD lock appeared on the file. And when I made a data
change, another SHRRD lock appeared, with a third SHRRD lock appearing
when I changed something else.
At no time, though, did I see any record locks.
This is getting interesting: just how do record locks work in SQL?
