Hello All Please help me in my below queries
Query#1 ------------ What is the purpose of these tmp-xxxx files and when are these generated? I added and updated the data for about 1 hour but no tmp-xxxx files was generated. The answer below says that "Named uses temporary files to create new versions of files then renames them to replace existing files atomically" It seems that, Named always generate temporary files and uses then for creating new versions of files. [This contradicts my observation above] Query#2 ------------ If the tmp-xxxx files are generated due to some errors (improper shutdown etc.) then does Named uses these tmp-xxxx files to correct its database after restart?

Named uses temporary files to create new versions of files then renames them to replace existing files atomically. This includes zone files, journals and any other file where a partial instance would be problematic. Now if something goes wrong in there generation the error handling is supposed to remove them but there can alway be omissions on error paths. Similarly if you don’t shutdown named cleanly there can be temporary files left around if named was in the process of updating a file. Similarly if named happens to die unexpectedly and it was in the process of writing out a file they will be left behind.
