NAME

bdii - services

DESCRIPTION

Service: bdii-update

The Berkeley Database Information Index (BDII) consists of two or more standard LDAP databases that are populated by an update process. Port forwarding is used to enable one or more databases to serve data while one database is being refreshed. The databases are refreshed cyclically. Any incoming connection is forwarded to the most recently updated database, while old connections are allowed to linger until it is the turn of their database to be refreshed and restarted. The update process obtains LDIF from either doing an ldapsearch on LDAP URLs or by running a local script (given by a URL with file protocol) that generates LDIF. The LDIF is then inserted into the LDAP database. Options exist to update the list of LDAP URLs from a web page and to use an LDIF file from a web page to modify the data before it is inserted into the database.

Configuration files: bdii-update.conf, bdii.conf

Service: bdii-fwd

The BDII fwd service is a TCP port forwarder that redirects request on the external service port to any of a set of backend ports, always taking the port of the most up-to-date slapd. Old connections are allowed to linger until their slapd is restarted. The bdii-fwd service is only started by the bdii-update service, never directly. The service is stopped by the bdii init script on terminating the bdii service.

Configuration files: bdii-fwd.conf (generated by bdii-update)

Service: bdii-proxy

Script to generate a proxy derived from the host certificate, to be made available to info providers that query secure services. It is called once when the BDII is started and henceforth regularly by a cron job.

Service: bdii

SystemV init script to start/stop the bdii-update service and the bdii-related slapd daemons. It will write the slapd.conf configuration files needed by the bdii slapd instances based on bdii.conf and the schemas file.

Configuration files: bdii.conf, schemas
