If you go into the Information Center under Programming/APIs/APIs by 
category/Database and File/File Information APIs you should find Retrieve 
Job Record Locks (QDBRJBRL) and Retrieve Record Locks (QDBRRCDL).  These 
two APIs, when used to analyze various steps within your application, 
should give you a good idea of who is holding locks a bit longer than you 
anticipated.

Hope this helps,

Unintended lock retention






Does anybody know of any good tricks for tracking down 
unintended lock retention on files?

We've got an application that keeps locking its own 
external calls out of records, even though we've got 
UNLOCK statements set to execute anytime an UPDATE 
operation fails, and all other attempts to read the file 
are either through logicals that are only open for input, 
or have an "N" option to disable locking.
