| # General Installation Considerations This chapter provides general installation considerations and tips. You must think in advance about the use and re-division of the system. Undersized or oversized hardware can cause problems while you work with the LN software. This chapter assumes your machine is sized by Infor and prepared for the LN software installation. For detailed information about the various database installations, refer to the relevant chapters on how to install the database. Also refer to Chapter “RDBMS administration,” of the Administrator’s Guide (U8854 US). Infor supports various relational databases (RDBMS) for which you can authorize the LN user. Note Check the Support Matrix of Infor ERP LN 6.1 in the Technical notes for Porting Set 8.6.This matrix supplies information about the supported versions of the Operating systems and RDBMS's. The Database Adminstrator determines the content, internal structure, access strategy, defines security and integrity, and monitors performance. Single Byte, Multi Byte or Unicode Character Set Before you start the installation you must have decided which Character Set you will be using for LN. Multi Byte and Unicode usage have significant impact on performance and an installation requires double the amount of disk space. Consult the Sizing Guides for the impact on your hardware. Deciding to change from Single Byte to Multi Byte or Unicode after the installation is a very time consuming conversion. MyDay The Infor components that are connected to LN through Infor Open SOA, such as MyDay and the MDMs, use Unicode as character set. Therefore, if you want to integrate LN with MyDay we recommend you have the LN environment Unicode enabled. Database Installation The LN installation requires a functioning installation of a certified database. Perform any post-database installation tasks required before the LN installation, such as tuning. For information on how to perform this installation, refer to the relevant chapters or appendices for each database. Users Create all database users and group names in lowercase, as some databases cannot handle uppercase characters. What if your database exists before the ERP LN installation? The LN installation allows you to create a new database or select an existing database. For best results, allow the LN installation to create the database for you. Check your log files After the installation, the log files for the installation can be located in %TEMP% on the client computer, as in the following example:
    C:\Documents and Settings\<username>\Local Settings\Temp\BaanERP Setup\<envname>
Alternatively, if you started the installation directly from the staging area, the log files are located in the directory logging files. Check these log files. C/S Scenario LN is always implemented in a client/server (C/S) mode. Therefore, the main parts of the LN architecture, including the presentation layer, application layer, and database layer, can run on separate machines. You can configure numerous C/S scenarios. However, most LN scenarios are based on two scenarios of the Gartner Group: Remote presentation scenario (2-Tier). Remote data management (3-Tier). In the 2-Tier scenario, the presentation layer runs on the client machine, usually a PC, and the server part contains the application and database layer. Because two machines are involved, this type of environment is called a 2-Tier environment. In the 3-Tier scenario, the application and the database layer run on separate machines. The display driver is started on a separate machine. For more detailed information, refer to the Sizing Guide. Master Application Server and Application Server Two different set-up types are available: Master Application Server (MAS), Application Server (AS). A Master Application server is a complete LN server that contains the application files and database. Having the database on the MAS is not mandatory. You can install the database on another server. The following LN components will be installed on the MAS: LN runtime data dictionary. Virtual machine. Database Driver. Audit Server. LN print manager. Solution License Manager (SLM). Note Before you install the Application Server, first install the Master Application Server. For specific information about the Application Server, refer to the Installation and Configuration Guide for Application Server (AS) (U8392 US) The following components will be installed on the Application Server: The Virtual machine, also known as the bshell. Installation Wizard The database-specific part of the Installation Wizard requires information about the following topics: Database server location. Database users and group. Database connection. Database configuration parameters. Database device locations and sizes. Database configuration files. For information about the various topics, refer to the online Help. Now continue with the database-specific installation chapter for the database that applies to your configuration. You can disregard the other database installation chapters. |
