NAME

       arc-infoindex-relay - ARC Information Index Relay Helper

DESCRIPTION

       The  arc-infoindex-relay command is used internally by the ARC Information System to relay
       queries and responses between the slapd server and the arc-infoindex-server

SYNOPSIS

       arc-infoindex-relay server-fifo

ARGUMENTS

       server-fifo
              The FIFO on which the arc-infoindex-server accepts queries

EXTENDED DESCRIPTION

       arc-infoindex-relay acts as a bridge between the slapd server and the arc-infoindex-server
       in the NorduGrid ARC Information system. For each index served by the arc-infoindex-server
       a shell backend database should be configured in the slapd configuration.

       Here is a sample configuration:

       database  shell
       suffix    "Mds-Vo-name=Sweden,o=Grid"
       bind      /usr/sbin/arc-infoindex-relay /var/run/arc/infosys/giis-fifo
       add       /usr/sbin/arc-infoindex-relay /var/run/arc/infosys/giis-fifo
       search    /usr/sbin/arc-infoindex-relay /var/run/arc/infosys/giis-fifo
       access to * by * write

       When a query for the configured database is recieved by the slapd server, the server  will
       call  out  to  the  arc-infoindex-relay.  The  arc-infoindex-relay will then open a unique
       return FIFO for this query and then forward the query and the name of the return  FIFO  to
       the arc-infoindex-server through the configured server FIFO. When the arc-infoindex-server
       has processed the query it will return the result to  the  arc-infoindex-relay  using  the
       return FIFO. The arc-infoindex-relay then closes the return FIFO and forwards the response
       to the slapd server.
