# arc-infoindex-server(8)

ARC Information Index Server

## NAME

arc-infoindex-server - ARC Information Index Server

## DESCRIPTION

The **arc-infoindex-server** accepts registrations about local information systems and other arc-infoindex-servers creating an hierarcical information system for discovering Grid resources

## SYNOPSIS

**arc-infoindex-relay** -c *conffile* -f *fifo*

## OPTIONS

- **-c** conffile

  The configuration file, usually /etc/arc.conf

- **-f** fifo

  The FIFO on which the server will accept queries

## EXTENDED DESCRIPTION

**arc-infoindex-server** accepts registrations with information about local information systems and other arc-infoindex-servers. It also responds to status queries returning the list of registered resources and their registration status (valid, invalid or purged).

Queries are accepted on a FIFO and are normally forwarded from a slapd server through an arc-infoindex-relay process. The first line of a query should contain the name of a FIFO on which the response should be returned. The remaining part of the query should be a Globus MDS query in LDIF format.

To stop arc-infoindex-server write the special query "STOP" to the server FIFO.

## FILES

- **/etc/arc.conf**

  Several resource indices can be kept in the same server. Each of them should have an \[infosys/index\] block in the configuration file. The set of resoures that are allowed to register to each index can be limited using allowreg keys.

  Here is an example configuration:

  ```
  [infosys/index/Sweden]
  allowreg="*.uu.se:2135"
  allowreg="*.lu.se:2135"
  allowreg="*.liu.se:2135"
  allowreg="*.umu.se:2135"
  allowreg="*.chalmers.se:2135"
  allowreg="*.kth.se:2135"
  ```
