Managing the Server as a Service
For optimal performance, your system must have sufficient RAM memory for the JVM heap and database cache. For more information on setting the JVM heap and database cache, see Configuring the JVM, Java Options, and Database Cache.
On Solaris systems, the operating system should be configured to have at least twice as much virtual memory as JVM heap. To achieve this, you might need to increase the size of the operating system swap space.
Your system should also have enough disk space to store the generated log files. The server log files can consume up to 1 Gbyte of disk space with default server settings. In replicated environments, the change log database can grow up to 30-40 Gbytes with loads of 1000 mods/sec. For information on setting log file size, see Managing Administration Traffic to the Server in Sun OpenDS Standard Edition 2.2 Administration Guide.
You can configure Sun OpenDS Standard Edition in such a way that it uses substantially less, or more, disk space depending on your application and performance needs. Any setup considerations must determine the amount of memory for the server's database and log files.
As a general guideline, the following hardware is recommended:
