Vimal, In customizing your framework, you would have encountered the list of MARC fields. (by clicking on 'Marc Structure' against your framework) One of the columns in this table (between 'repeatable' and 'auth value') states whether the particular field is "Mandatory" or not. For e.g., 000 Leader is almost always mandatory Unfortunately, this table cannot be 'sorted' by its columns, so there is no alternative but to run through several screens to find out which of the 900+ fields are currently mandatory.. You can then edit the sub-fields and un-check that 'mandatory' option. Perhaps there's a simple database query that will give you the answer, but i don't have access to a database right now to send you one. i have very little cataloging experience, but i would caution you against arbitrary decisions on toggling a mandatory tag to make it optional. Generally, for example, with the leader tag itself, Koha itself will generate a value for the tag while cataloging, if you click within the box or on the ellipsis next to one. But, clearly, this is just a set of defaults that does not necessarily make sense, so you may end up with a tag that has very little relevant information in it. As a non-librarian that encountered cataloging when using Koha, i was mightily irritated to come up short against mandatory tags that i could not make sense of. regards, krishnan ________________________________ From: vimal laxman <vimallaxman@gmail.com> To: Joe Atzberger <ohiocore@gmail.com> Cc: koha@lists.katipo.co.nz Sent: Monday, 29 December, 2008 12:09:27 PM Subject: Re: [Koha] installation help for KOHA 3.0 Thanks Joe, I made it at last.The problem was that the zebra daemon was not running.i folowe option 2 for running the zebra process as daemon.then i tried option 1 as indicted in the Installation document and the search engine worked. and about the barcode stuff i did the same way as you told me to .it had some problems initially like the items location was not defined and item type was not getting saved properly.after a few strugle i was able to Check out the book sucessfully. Now that i have to add some of the books manually because they are not available online.indoing that i have customized my framework to just a few key fields.but when i entered them manually and tried to save them the application gives an error saying "cannot be saved with Tag =''".it says i have left some of the subfilds empty but i made sure that i have entered the data for all the fields and subfields. could sny one suggest me a way to enter this manually. regards, vimal On Tue, Dec 23, 2008 at 12:06 PM, Joe Atzberger <ohiocore@gmail.com> wrote: Vimal -- On Tue, Dec 23, 2008 at 5:02 AM, vimal laxman <vimallaxman@gmail.com> wrote: 1.when i search for books through OPAC it says 'no results found' in catalogue(i have a few books which i imported using Z39.50 search)and error log says" biblio erro 109'.I know this is a basic issue but still i could not find out a right solution.i followed all the instructions that were give in the INSTALL.debian file.devolopers in the community say it is a databse related issue.if so can you let me know how to check whether my database is set to right encoding for Koha 3.0 to read. When you run rebuild_zebra you have to remember to set and export KOHA_CONF and PERL5LIB, but it sounds like you have done this. Then, check your zebra logs for additional information about the errno 109. 2.I dont have a barcode reader with me here.i wish to do the 'Check IN' and 'Check OUT' manually.one person suggested me that i map the barcode field in Administration->Koha to MARC Mapping->items->Barcode to a field of our choice .so i mapped it to ISBN.and i tried to Check Out a particular Patron by manually entering the ISBN number of a particular book that is available in the database.It says 'Barcode not foud'.is it possible for us to do it manually through keyboard withour using barcode reader ?. I have already responded in this thread why it would be a bad idea to try to use ISBN. Even if you don't have a barcode scanner, it will still be more reliable and easier for you to use a self-generated barcode manually than to use the ISBN. Even if you don't have a printer and you just use a typewriter or a pencil, it will be easier than trying to use the ISBN. If you use incremental barcodes, then instead of having to key in at least 10 digits, it would be as small a number of keystrokes as possible. Unlimited freedom, unlimited storage.
