We are experiencing some issues with Files being left open […]

My question is can we find which program has left a particular
instance of file open so that we can identify and correct these
issues quickly?


One possibility would be to start journaling the physical files but _do not omit_ the Open\Close (*OPNCLO) entries when Start Journal Physical File (STRJRNPF); i.e. specify *NONE for the Journal Entries To Be Omitted (OMTJRNE). The logged entry will include the program that opened the file.

Another possibility is to collect a trace of a request known to leave the file(s) open when not desired; the trace data logs the open of the file.member [TRCJOB *ON and TRCJOB *OFF, or, IIRC, the STRTRC and ENDTRC combo].

There is also a Database Open-File Exit feature that can track all opens: [Open Database File (QIBM_QDB_OPEN) exit program is called when a when a job is opening a database file.](http://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_71/apis/xopendbf.htm)
