Опис

Параметри:

-b

— index bibliographic records

-a

— index authority records

-daemon

— Run in daemon mode. The program will loop checking

for entries on the zebraqueue table, processing

them incrementally if present, and then sleep

for a few seconds before repeating the process

Checking the zebraqueue table is done with a cheap

SQL query. This allows for near realtime update of

the zebra search index with low system overhead.

Use -sleep to control the checking interval.

Daemon mode implies -z, -a, -b. The program will

refuse to start if options are present that do not

make sense while running as an incremental update

daemon (e.g. -r or -offset).

-sleep 10

— Seconds to sleep between checks of the zebraqueue

table in daemon mode. The default is 5 seconds.

-z

— select only updated and deleted

records marked in the zebraqueue

table. Cannot be used with -r

or -s.

--skip-deletes

— only select record updates, not record

deletions, to avoid potential excessive

I/O when zebraidx processes deletions.

If this option is used for normal indexing,

a cronjob should be set up to run

rebuild_zebra.pl -z without --skip-deletes

during off hours.

Only effective with -z.

-r

— clear Zebra index before

adding records to index. Implies -w.

-d

— Temporary directory for indexing.

If not specified, one is automatically

created. The export directory

is automatically deleted unless

you supply the -k switch.

-k

— Do not delete export directory.

-s

— Skip export. Used if you have

already exported the records

in a previous run.

-nosanitize

— export biblio/authority records directly from DB marcxml

field without sanitizing records. It speed up

dump process but could fail if DB contains badly

encoded records. Works only with -x,

-w

— skip shadow indexing for this batch

-y

— do NOT clear zebraqueue after indexing; normally,

after doing batch indexing, zebraqueue should be

marked done for the affected record type(s) so that

a running zebraqueue_daemon doesn't try to reindex

the same records - specify -y to override this.

Cannot be used with -z.

-v

— increase the amount of logging. Normally only

warnings and errors from the indexing are shown.

Use log level 2 (-v -v) to include all Zebra logs.

--length 1234

— how many biblio you want to export

--offset 1243

— offset you want to start to

example: --offset 500 --length=500 will result in a LIMIT 500,1000 (exporting 1000 records, starting by the 500th one

)

note that the numbers are NOT related to biblionumber, that's the intended behaviour.

--where

— let you specify a WHERE query, like itemtype='BOOK'

                           or something like that

--run-as-root

— explicitily allow script to run as 'root' user

--wait-for-lock

— when not running in daemon mode, the default

behavior is to abort a rebuild if the rebuild

lock is busy. This option will cause the program

to wait for the lock to free and then continue

processing the rebuild request,

--table

— specify a table (can be items, biblioitems, biblio, biblio_metadata) to retrieve biblionumber to index.

biblioitems is the default value.

--help or -h

— show this message.
