Common pre-installation tasks

The term common is used in this chapter to indicate a task required for all LN installations, regardless of the database package is being used. For detailed information, this document refers you to chapters in this document, or other documents. This chapter provides a short overview of the process you must follow to start the Staging Wizard.

Hardware and software requirements

Representing standard values in this document is difficult. Numerous hardware and software combinations are possible with the LN software. Multiple criteria determine the size of your hardware and the way the software is applied to achieve the best performance. Consider a sizing by Infor. Incorrect values can negatively impact performance.

In addition to the assumption that your machine is sized by Infor and completely prepared for the LN software installation, you must also meet the following requirements:

One of the certified databases, Oracle, MySQL, Informix or DB2, must be installed and running.
FTP and Rexec daemon must be up and running on the Unix Server (destination server). In case of changes restart the initd.
Client computer with Microsoft Windows with TCP/IP and FTP software must be installed and running to create a connection to the UNIX server. To find out which windows versions are supported please refer to the technical notes.

Note

Modify the firewall in such a way that ftp and rexec connection can take place. Otherwise, the firewall will prevent the port access for the ftp transfer.

Common Unix tasks

Before you can install LN on UNIX, you must perform several common tasks, as described in the following sections.

Korn Shell (ksh)

Activate the korn schell to avoid installation problems.

Tune the kernel

The kernel of the UNIX machine must be tuned to accommodate the projected number of ERP LN users and database. For more specific information about the kernel for LN, refer to the Enterprise Server Technical Manual (U8172 US).

To allocate disk space

To allocate disk space, consider your disk usage. Estimate the future disk space to avoid future performance problems. The process to change the allocations after you allocate disk space is usually very time-consuming. To properly allocate the available disk space, consider a number of factors, such as:

disk capacity.
number of concurrent users.
number of companies.
future disk space needs.

The following table provides an example of how you can allocate disk space to set up your machine:

**Disk space allocation**
File system	Disk space	Description
/usr1	1 GB	Database binaries
/usr2	2 GB	LN binaries
/usr3	1 GB	Database files
/usr4	4 GB	Data files for LN
/usr5	Database dependant	Database log files

To create the UNIX group bsp

Before you can install LN, you must have the UNIX group account bsp. To add this group, you can use a standard system administration utility.

The bsp group includes those users who are given system administration privileges for the LN tables. The group bsp must be given the UNIX group ID 125.

To create UNIX users

The following users are created in the users session of LN:

**UNIX users and groups**
Logon ID	Primary group
bsp	bsp
demo	bsp
applic	bsp

To create these users on Unix, use a standard system administration tool. The users demo and applic are optional. However, the user bsp is mandatory. Set the bsp group as primary group. You can change this setting later if the users must access the LN database with another group name.

Note

In some cases additional user accounts are needed for certain RDBMS’s in combination with ERP LN 6.1.

For example with IBM Informix Dynamic Server an additional user is required. This user is called database group user and owns the database. It is common to use a name like infordb.

Also DB2 is one of the databases that need extra accounts.
