I have just installed cnews on my system (NCR Tower 32/650, SYSVR2) and I have a question. It seems that the unbatching of articles is taking forever! There are currently 75 newsbatches left to run, some have been in the queue for 18 hours! The unbatching has been running for 17 of those 18 hours, but it sure doesn't seem to be making any progress! Does anyone out there have any suggestions? The news filesystem was remade less than 2 weeks ago to increase the # of inodes, it is now about 60% full. I don't believe that this is the problem. Where can I look? Thanks. Bob -- =========================================================== Name: Bob Earl Phone: (202) 872-6018 (wk) UUCP: ...!uunet!wash08!rae98 BITNET: rae98@CAS

Are you using the original fake dbm library, or dbz? If the former, switch to the latter. The old fake is much more of a performance disaster than we first thought, whereas dbz performs very well. (You can find dbz in the contrib directory. Note that you will need to rebuild your history file.) As soon as I can find some time to work on it -- Geoff and I do get paid to work on other things than C News! -- the old fake will vanish completely and dbz will become the definitive dbm replacement. -- "Where is D.D.

Many thanks to the numerous thoughtful souls who recommended using the dbz routines. News unbatching now proceed at the rate of 2-5 articles per second as opposed to 1-2 per minute.

You might want to find out if you are getting a batched feed or each article individually fed to rnews. Unless I've drasticly misunderstood Henry Spencer the latter should have "dreadful" performance. Hope that this helps. Share and Enjoy! Brian (haug@Columbia.NCR.COM)

I took the lazy way out and switched to dbz and have been getting 1-2 articles/sec without problems. (Down from 4-6/min, Thanks Henry and Geoff!)

Bob, I had a similar problem with the installation and it seemed to be caused by lines in some news articles being longer than 256 characters. I wrote a filter to cut such lines in two (or more) and have had no further problems. Hope it works for you. Barry Mahoney.
