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