[Koha] FW: Error appearing upon scanning/entering Barcodes - PLEASE HELP!!!

Thu Sep 1 02:08:07 NZST 2011

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
