Partitioning the Database

The search server allows you to put the physical files that make up each search database on multiple disks, file systems, directories, or partitions. By spreading databases across different physical or logical devices, you can create a larger database than would fit on a single device.

By default, the search server sets up the database to use only one directory. The command-line interface allows you to perform two kinds of manipulations on the database partitions:

• Adding New Partitions

• Moving Partitions

The search server does not perform any checking to ensure that individual partitions have space remaining. It is your responsibility to maintain adequate free space for the database.

You can add new database partitions up to a maximum of 15 total partitions.

Once you increase the number of partitions, you must delete the entire database if you want to reduce the number later.

However, partitions are not recommended as long as you have enough disk space.

To change the physical location of any database partition, specify the name of the new location. Similarly, you can rename an existing partition. Use the rdmgr command to manipulate the partitions. See the Sun Java System Portal Server 7.1 Command Line Reference for information on the psadmin command.
