Re: File version limits on NTP log files
The version limit protects you agains too many version of a file. There is no protection against reaching the maximum version. The only thing you can do is delete/rename the file(s), depending on its usage.
Some software will stop working when the maximum version is reached, some will simply not write output if the open fails. Your NTP is in the 2nd group.

Re: File version limits on NTP log files
reading Garry & Wim, at least it is clear that your question is not clear.
Is your trouble: A> with .LOG files versions exceeding 32767, or B> is the problem that you have /VERSION=x, and there are more than x files?
If A>, Wim ' s answer applies, if B> then see Garry.
hth,
Proost.
Have one on me.

Re: File version limits on NTP log files
Its normal. Some people create a file with the highest version number just to prevent creation of log files.
Purely Personal Opinion

Re: File version limits on NTP log files
Owner: [TCPIP$AUX,TCPIP$NTP]
File protection: System:RWED, Owner:RWED, Group:RE, World:
which seems reasonable.
Correct me if I am mistaken but as I read Ianâ s and Wimâ s responses, they took my question as if I had reached the maximum version limit of a VMS file of 32767 which is not what I was meaning.
To restate my question, I have used SET FILE/VERSION_LIMIT=20 on the NTP log file
SYS$SPECIFIC:[TCPIP$NTP]TCPIP$NTP_RUN.LOG;922
after temporally disabling NTP so as to release the file. After restarting NTP, a new log file gets created each day for 20 days (file version limit =20) and thereafter, no more log files are created even though NTP is still running. (In operation, NTP automatically opens a new log file each day to record its status each reporting period.of that 24 hour day)
I have attached a copy of a DIR/DATE output showing the files, versions number and date illustrating my question.
I will not be viewing responses tomorrow as it is Canada Day our national Birthday so any questions will be answered Monday.

Re: File version limits on NTP log files
are you restarting NTP every day? On all of our systems, NTP does NOT create a new logfile every day.
A version limit on a file does NOT prevent the creation of a new version, if reached. Instead the oldest is deleted and a new version created, so that exact N versions are present.

SolutionSince the first file can't be deleted because it's open, this could be preventing the version
limit from working as expected.

Re: File version limits on NTP log files
I tried to simulate the behavior using simple DCL commands: OPEN/APPEND holding the lowest version numbered file open; COPY NL: to create a new version of the file. I'm not happy with what I observed. I attached the output. IMHO this also should be reported to HP.

Re: File version limits on NTP log files
Keith- I think you have answered the problem. I did check and found as you and Gary did that the first version is still open.
Gary, your simulation of the behavior is very interesting. When is "not copied" really copied :-). As stated above, in past I have not felt it worth calling HP but I think the next time I do log a trouble call, I will include this and Gary's example as well
Thanks all
Don

Re: File version limits on NTP log files
Purging reduces number of files, not the version limit.

Re: File version limits on NTP log files
in my experience version limit purges files. In your report log fileshave version from 922 to 941 that's exactly 20 files.
Excecuting SHO DEV /FILE you could see if and what processes keep file opened.

Re: File version limits on NTP log files
As I reported in my response to Keith and Gary yesterday, I to like they had reported, had found a NTP process (TCPIP$NTP_1 to be precise) kept the first log file open as shown by SHO DEV/FILE. As such,Gary's suggestion seems to answer my question.
The question I would have now is why does NTP keep the first log file open. I think this is a question for HP, is it a fault or part of their design?
Thanks
Don
