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 received 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.
