Vincent -- Yes is it possible to switch between zebra and "nozebra" index modes. In Koha, these are controlled by a value in the systempreferences table: SELECT * FROM systempreferences WHERE variable="NoZebra" Of course you could not search successfully after switching NoZebra OFF if zebra itself is not installed, or if the zebrasrv process is not started. The main difficulty in switching would be dealing with the regularly scheduled rebuilding of the index, since the job scheduled in crontab is one of these two: - misc/migration_tools/rebuild_zebra.pl - misc/migration_tools/rebuild_nozebra.pl You would not want to run the wrong one from crontab after you have switched. And you would have to run the correct one immediately after switching. Perhaps we should encapsulate the two scripts behind a common "rebuild_index" script. We may want to consider deprecating nozebra altogether (and I would support this), which would also solve this problem. The people who have problems installing and configuring zebra are the same people who would benefit here by nozebra deprecation. Previously the argument for nozebra was simplicity or potential platform-incompatibility, but for a linux package they can apt-get reliably, there is no advantage to nozebra. Thanks for your work on this. --Joe Atzberger, LibLime On Wed, Oct 29, 2008 at 6:07 PM, Vincent Danjean <vdanjean.ml@free.fr>wrote:

Hi,

As I've a few free time, I'm trying to complete a first version of Debian Koha packaging. I've a few questions for koha/zebra/.. guru that I separate in 3 mails.

Here is the second mail.

I would like koha users to be able to do 'dpkg-reconfigure koha' to modify most of the config. However, I've some question about the switches.

I know how to configure apache, so I have no question about koha-httpd.conf.

If we want to switch from a koha with zebra to a koha without zebra: - is it possible? - what must be done? (in addition to change config files)

If we want to switch from a koha without zebra to a koha with zebra: - is it possible? - what must be done? (in addition to change config files)

If we want to enable the SRU server on a koha with zebra: - is it possible? - what must be done? (in addition to change config files) (only restart zebrasrv?)

If we want to disable the SRU server on a koha with zebra: - is it possible? - what must be done? (in addition to change config files) (only restart zebrasrv?)

If we want to enable the PAZPAR2 server on a koha with zebra: - is it possible? - what must be done? (in addition to change config files) (only restart zebrasrv and start pazpar2?)

If we want to disable the PAZPAR2 server on a koha with zebra: - is it possible? - what must be done? (in addition to change config files) (only restart zebrasrv and stop pazpar2?)

If we want to switch the authorities indexing mode (dom <-> grs1) on a koha with zebra: - is it possible? - what must be done? (in addition to change config files) (only restart zebrasrv?)

If we want to switch the primary language for Zebra indexing (en <-> fr) on a koha with zebra: - is it possible? - what must be done? (in addition to change config files) (only restart zebrasrv?)

If we want to switch the MARC format for Zebra indexing (MARC 21 <-> UNIMARC) on a koha with zebra: - is it possible? - what must be done? (in addition to change config files) (only restart zebrasrv?)

So, if any guru can confirm/answer to my guesses, it would be easier for me to manage the configuration files without messing up all things and allowing a flexible koha reconfiguration on Debian.

Best regards, Vincent
