493 marc_stream_importer.pl - Import MARC records via bare socket connection.
497 ./marc_stream_importer.pl [common opts ...] [script opts ...] -- [Net::Server opts ...] &
499 This script uses the EG common options from B<Cronscript>. See --help output for those.
501 Run C<perldoc marc_stream_importer.pl> for full documentation.
503 Note the extra C<--> to separate options for the script wrapper from options for the
504 underlying L<Net::Server> options.
506 Note: this script has to be run in the same directory as B<oils_header.pl>.
508 Typical server-style execution will include a trailing C<&> to run in the background.
512 This script is a L<Net::Server::PreFork> instance for shoving records into Evergreen from a remote system.
516 The only required option is --password
518 --password =<eg_password>
519 --user =<eg_username> default: admin
520 --source =<bib_source> default: 1 Integer
521 --merge-profile =<i> default: 0
522 --tempdir =</temp/dir/> default: from L<opensrf.conf> <open-ils.vandelay/app_settings/databases/importer>
523 --source =<i> default: 1
524 --import-by-queue =<i> default: 0
525 --spoolfile =<import_file> default: NONE File to import in --nodaemon mode
526 --nodaemon default: OFF When used with --spoolfile, turns off Net::Server mode and runs this utility in the foreground
529 =head2 Old style: --noqueue and associated options
531 To bypass vandelay queue processing and push directly into the database (as the old style)
533 --noqueue default: OFF
534 --buffsize =<i> default: 4096 Buffer size. Only used by --noqueue
535 --wait =<i> default: 5 Seconds to read socket before processing. Only used by --noqueue
537 =head2 Net::Server Options
539 By default, the script will use the Net::Server configuration file B<marc_stream_importer.conf>. You can
540 override this by passing a filepath with the --conf_file option.
542 Other Net::Server options include: --port=<port> --min_servers=<X> --max_servers=<Y> and --log_file=[path/to/file]
544 See L<Net::Server> for a complete list.
548 =head3 OCLC Connexion
550 To use this script with OCLC Connexion, configure the client as follows:
552 Under Tools -> Options -> Export (tab)
553 Create -> Choose Connection -> OK -> Leave translation at "None"
554 -> Create -> Create -> choose TCP/IP (internet)
555 -> Enter hostname and Port, leave 'Use Telnet Protocol' checked
556 -> Create/OK your way out of the dialogs
557 Record Characteristics (button) -> Choose 'UTF-8 Unicode' for the Character Set
560 OCLC and Connexion are trademark/service marks of OCLC Online Computer Library Center, Inc.
564 WARNING: This script provides no inherent security layer. Any client that has
565 access to the server+port can inject MARC records into the system.
566 Use the available options (like allow/deny) in the Net::Server config file
567 or via the command line to restrict access as necessary.
