Capability is there. For example:
DSPFD FILE(SYSIBM/SYSDUMMY1)
Allow read operation . . . . . . . . . . . : Yes
Allow write operation . . . . . . . . . . . : No
Allow update operation . . . . . . . . . . : ALWUPD *NO
Allow delete operation . . . . . . . . . . : ALWDLT *NO
Restrict on drop . . . . . . . . . . . . . : No

Some of these are turned on/off by simple operations. An example would be
the history file for temporal tables. When it's 'active' you cannot write
or update it. It does allow deletes so you can purge old records.

With that being said I'm not sure how mortals control this.
An option would be to add a trigger on the file and that trigger would put
a stop to any deletes.

In the S/36 days, I recall that a file could be created so that records
could not be deleted from them. I'm looking for a way to do this using a
PF in DDS, but I'm not seeing it. Is this just not an option in IBM i DB2
for a physical file?
