      <Paragraph>The term <Emphasis>common</Emphasis> 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.</Paragraph>

      <SectionTitle>Hardware and software requirements</SectionTitle>
      <Paragraph>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.</Paragraph>
      <Paragraph>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:</Paragraph>
      <List>
         <ListItem>One of the certified databases, Oracle, MySQL, Informix or
		  DB2, must be installed and running.</ListItem>
         <ListItem>FTP and Rexec daemon must be up and running on the Unix Server
		  (destination server). In case of changes restart the initd.</ListItem>
         <ListItem>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.</ListItem>
      </List>
      <Note>
         <SectionTitle>Note</SectionTitle>
         <Paragraph>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.</Paragraph>

      <SectionTitle>Common Unix tasks</SectionTitle>
      <Paragraph>Before you can install LN on UNIX, you must perform several common tasks,
		as described in the following sections.</Paragraph>
      <GeneralSection>
         <SectionTitle>Korn Shell (ksh)</SectionTitle>
         <Paragraph>Activate the korn schell to avoid installation
		  problems.</Paragraph>

      <GeneralSection>
         <SectionTitle>Tune the kernel</SectionTitle>
         <Paragraph>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).</Paragraph>

         <SectionTitle>To allocate disk space</SectionTitle>
         <Paragraph>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:</Paragraph>
         <List>
            <ListItem>disk capacity.</ListItem>
            <ListItem>number of concurrent users.</ListItem>
            <ListItem>number of companies.</ListItem>
            <ListItem>future disk space needs.</ListItem>
         </List>
         <Paragraph>The following table provides an example of how you can
		  allocate disk space to set up your machine:</Paragraph>

		  mandatory. Set the bsp group as primary group. You can change this setting

            <Paragraph>In some cases additional user accounts are needed for

            <Paragraph>For example with IBM Informix Dynamic Server an additional
			 user is required. This user is called <GUIRef href="" role="manual">database group user</GUIRef> and
			 owns the database. It is common to use a name like <GUIRef href="" role="manual">infordb</GUIRef>.</Paragraph>
            <Paragraph>Also DB2 is one of the databases that need extra
			 accounts.</Paragraph>
