10 The arc-infoindex-relay command is used internally by the ARC Informa‐
11 tion System to relay queries and responses between the slapd server and
12 the arc-infoindex-server

21 The FIFO on which the arc-infoindex-server accepts queries
22
24 arc-infoindex-relay acts as a bridge between the slapd server and the
25 arc-infoindex-server in the NorduGrid ARC Information system. For each
26 index served by the arc-infoindex-server a shell backend database
27 should be configured in the slapd configuration.
28
29 Here is a sample configuration:
30
31 database shell
32 suffix "Mds-Vo-name=Sweden,o=Grid"
33 bind /usr/sbin/arc-infoindex-relay /var/run/arc/infosys/giis-fifo
34 add /usr/sbin/arc-infoindex-relay /var/run/arc/infosys/giis-fifo
35 search /usr/sbin/arc-infoindex-relay /var/run/arc/infosys/giis-fifo
36 access to * by * write
37
38 When a query for the configured database is received by the slapd
39 server, the server will call out to the arc-infoindex-relay. The arc-
40 infoindex-relay will then open a unique return FIFO for this query and
41 then forward the query and the name of the return FIFO to the arc-
42 infoindex-server through the configured server FIFO. When the arc-
43 infoindex-server has processed the query it will return the result to
44 the arc-infoindex-relay using the return FIFO. The arc-infoindex-relay
45 then closes the return FIFO and forwards the response to the slapd
46 server.
