Distributing Your Data
About Using Multiple Databases
Directory Server stores data in LDBM databases.The LDBM database is a
high-performance disk-based database. Each database consists of a set of large files
that contains all of the data assigned to it.
You can store different portions of your directory tree in different databases. In that
instance, your directory tree appears as follows:
You can also store the data of the three suffixes in three separate databases, as
shown below:
When you divide your directory tree among a number of databases, these
databases can then be distributed across multiple servers. For example, the three
databases you created to contain the three suffixes of your directory tree can be
stored on two servers, as follows:
Server A contains databases one and two, and server B contains database three.
