FW: Error appearing upon scanning/entering Barcodes - PLEASE HELP!!!
From: joel.harbottle@hotmail.com.au To: cnighswonger@foundations.edu Subject: RE: [Koha] Error appearing upon scanning/entering Barcodes - PLEASE HELP!!! Date: Wed, 31 Aug 2011 23:57:08 +1000 Hi All, Before upgrading from Koha 2.2.9 on Windows Server 2003 to Koha 3, I set up a virtual test server of Koha 3 on my Mac with this test install using Zebra. With Zebra enabled in my test environment, I found that when I added items to the Bibliographic database, I had to wait a good ten minutes for Zebra to reindex before that Bibliographic Record/Item Record would appear in the OPAC, whereas with 'NoZebra' the Bibliographic Record/Item Record appears immediately in the OPAC once you click 'add' in the Staff Client. I like to know I have the functionality of when I add in an item to the system, that it will instantly appear in the OPAC, and not have to wait ten minutes for Zebra to reindex every time a record is added to the database. My test environment was on a Intel Core 2 Duo machine with 4GB RAM. I hope that sheds some further light on my choice of 'NoZebra'. I'm hoping there is someone out there in the Koha Community whom is able to help me past this problem I'm having.

To: Joel.Harbottle@hotmail.com.au CC: koha@lists.katipo.co.nz It should probably be pointed out that No Zebra code will probably be removed at some point in the future. So along with the fact that it is deprecated and unsupported, it is really a dead end road as well. Kind Regards, Chris 2011/8/30 Liz Rea <lrea@nekls.org> I should add that collections over 10k, we usually really recommend using Zebra for indexing. As a data point for you, I have run a functioning library with 8k or so records with zebra on a P4 with 1G of RAM. So, zebra isn't *that* big of a hog. You could do it on very modest hardware.

Joel, Sorry to hear you're having trouble. I have a few questions, if you don't mind. What operating system are you running Koha on? Which minor release of 3.4 (the last digit is important)? Is this a new install or an upgraded install? If it is an upgraded install, was the previous install running with the zebra indexer or with the nozebra preference set? If it's Zebra, have you done a full reindex? (/home/koha/kohaclone/misc/migration-tools/rebuild_zebra.pl -b -v) Do you get results when you search? Are you using a translation? Have you changed or edited your bibliographic frameworks? The answers to these questions will help us figure out where to begin suggesting fixes for you. Thanks!

Joel, The reindex lag is less than optimal, true, but it can be adjusted to less than 10 minutes by changing your crontab entry for rebuild_zebra.pl. */10 * * * * $KOHA_PATH/misc/migration_tools/rebuild_zebra.pl -x -b -z to * * * * * $KOHA_PATH/misc/migration_tools/rebuild_zebra.pl -x -b -z which will run every minute. It's not currently possible to run faster than that, just given the nature of cron. This is an area of active interest, and hopefully a working zebraqueue_daemon can be recreated to do indexing in realtime, but until then, this is what can be done. I don't think that the lag is enough to warrant ditching Zebra completely, but of course it's not my system :) Cheers, -Ian 2011/8/31 Joel Harbottle <joel.harbottle@hotmail.com.au>
