Database (DBA) Extensions –
In general DBA Extensions are used to take advantage of RDBMS and SQL statements to create Forms, indexes and allocate space to them. Creating DBA extensions is a advance performance tuning mechanism very few of Remedy Admins does, when they run out of all other possible ways to fine tune the system.
DBA extensions are mainly used to manage database space and improve overall system performance.
DBA extensions provide:
> Vast control over location and size allocation for tables and indexes
> Automatically referenced by the AR System during initial table and index creation
> Automatically referenced by the AR System during table rebuild operations
> Allows for Vendor specific customization.
DBA Extensions are implemented using a database configuration file (ardb)
This file is normally located in the following directory:
- Unix – /etc/ardb.conf
- Windows – AR_System_Install\Conf\ardb.cfg
