gLite 3.2

gLite BDII_top


The Berkeley Database Information Index (BDII) consists of two or more standard LDAP databases that are populated by an update process. Port forwarding is used to enable one database to serve data while the other is refreshing. The update process obtains LDIF from either doing an ldapsearch on LDAP URLs or by running a local script that generates LDIF. The LDIF is then inserted into the LDAP database. Options exist to update the the list of LDAP URLs from a web page and to use an LDIF file from a web page to modify the data before inserting it into the database.

For a quick overview on the Information System, please check the Information System Overview.

For further details on the BDII, please check the Berkeley Database Information Index twiki page.

Supported platform
The gLite 3.2 software stack is supported on Scientific Linux 5 (SL5).

The gLite BDII is available in RPM format. The recommended installation is via the gLite YUM repository. You can find the installation instructions here.

Due to the critical nature of the information system with respect to the operation of the grid, the BDII should be installed as a stand-alone service to ensure that problems with other services do not affect the BDII. In no circumstances should the BDII be co-hosted with a service which has the potential to generate a high load. To achieve the desired scalability, multiple BDII  instances should be deployed behind a round-robin DNS alias in order to provide a load balanced BDII service.

RPM Installation via YUM
The yum-module name is glite-BDII_top.
