Database server configuration during installation

You can choose to create and configure a database server during installation. The database server is configured by the choices that you make in the installation application. After installation is complete, disk space for the database server is initialized and the database server is started.

All mandatory configuration parameters and environment variables are set and default connectivity information is configured. The database server is also configured to require minimal administration. The database server is configured to automatically tune resources for performance, which include expanding the buffer pool, the logical logs, and the physical log, and increasing virtual processors. You can further customize the database server by setting other configuration parameters and environment variables.

Important: If you plan to use a locale or language other than the default (US English), set the appropriate global language support (GLS) environment variables before you create a database. For example, to prevent server and collation problems, it is crucial to set the GL_USEGLU environment variable correctly. The same Unicode collation must be used for the database and the client application environment.

The following storage spaces are created for an installation of the database server:

  • A root dbspace to contain control and tracking information
  • An extendable plogspace for the physical log
  • A dbspace for the logical logs
  • A temporary dbspace
  • An sbspace
  • A temporary sbspace
  • Dbspaces for data:
    • Typical installation: Three extendable dbspaces with the default page size, and three extendable dbspaces with an 8 KB page size
    • Custom installation: One dbspace with the default page size

The sizes of the spaces are based on the number of expected users that you specify during the installation. The spaces are not encrypted. You can encrypt the storage spaces that are created during installation by enabling storage space encryption, running a backup, and then running a restore that encrypts the spaces.

If you run a typical installation, the server is configured with a JSON wire listener for connections to MongoDB applications. The JSON wire listener is started, and connected to the database server through the ifxjson user.

Windows: A program group for the database server is created from which you can open a command prompt for the server, start the Server Instance Manager, uninstall the database server, or view documentation.
