Just an update to all ... two batch runs (shell script) using 'mget' were able to succesfully transfer a few dozen files before stalling out on the same file each time. After killing the ftp, the file in question is in the target directory, and at first glance looks good .. it's file size is comparable to all of the others - in the 3.5 to 4.5 GB range. But comparison to the file on the source server shows the transferred file is still a few GB short of complete. Most of these files transfer in about 5 minutes.

Today I tried to pull it manually. Started ftp at a command line and did a simple 'get' on the one file. After 20 minutes I killed it. I also did a simple get on another file from the same set and it completed in about 4 minutes, exactly as expected. So it would appear that there is something about the individual file, but I don't know what it would be. It is part of an Oracle database backupset - created by oracle's rman utility. I ran an rman 'verify' against it and it came up clean from that standpoint.

So, I can conclude ..
  1. since it always hits on that one file and only that one file, I can eliminate transient network issues.
  2. since it occurs on that file whether as part of a batch transfer or just the single file, I can eliminate any 'ftp flooding' that I've seen reference to here and there.

At this point I'm just going to let the normal weekend process run again on schedule, but if anyone has any good theories that fit all of the observations so far, I'd be willing to entertain them. If not, I'll have to figure the problem has been found to be off-topic for this forum.

bbretest-net.sh

BBRETEST-NET.SH(1)					      General Commands Manual						BBRETEST-NET.SH(1)

NAME

       bbretest-net.sh - Xymon network re-test tool

SYNOPSIS

       bbretest-net.sh

DESCRIPTION

       bbretest-net.sh	is  an extension script for Xymon that runs on the network test server.  It picks up the failing network tests executed by
       the bbtest-net(1) program, and repeats these tests with a faster test cycle than the normal bbtest-net schedule. This means that  when  the
       server recovers and the network service becomes available again, this is detected quicker resulting in less reported downtime.

       Only  tests  whose first failure occurred within 30 minutes are included in the tests that are run by bbretest-net.sh.  The 30 minute limit
       is there to avoid hosts that are down for longer periods of time to bog down bbretest-net.sh.  You can change this limit with  the  "--fre-
       quenttestlimit=SECONDS" when you run bbtest-net.

INSTALLATION

       This script runs by default from your hobbitlaunch.cfg(5) file.

FILES

       $BBTMP/TESTNAME.LOCATION.status
	      Temporary status file managed by bbtest-net with status of tests that have currently failed.

       $BBTMP/frequenttests.LOCATION
	      Temporary file managed by bbtest-net with the hostnames that bbretest-net.sh should test.

SEE ALSO

       bbtest-net(1), xymon(7), hobbitlaunch.cfg(5)
