	<AimSection><Paragraph class="Default">The application administration consists of a number of tasks that the system administrator must perform with care and precision.</Paragraph>
	</AimSection>
	<GeneralSection><SectionTitle>Act as contact person</SectionTitle>
		<Paragraph class="Default">The system administrator is the contact person between a company and ERP LN. The application administrator is responsible to find a solution for the questions and problems brought forward by the ERP LN users. If required, this task will be performed by contacting one of the Global Support Centers.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Have extensive knowledge about the application environment</SectionTitle>
		<Paragraph class="Default">The system administrator must know in which directories the ERP LN application resides. For example, to make a backup or to rebuild tables, the system administrator must know the exact location of the files and programs involved.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Reorganize tables</SectionTitle>
		<Paragraph class="Default">The system administrator must frequently reorganize the database tables because the disk space of deleted records will not immediately be given back to the system. In other words, although many records in a table are deleted, the size of the table itself will not become smaller. Only after the table has been reorganized will the disk space of the deleted records become available on the system. Reorganizing the database tables becomes very important when many records in tables are deleted.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Control disk space</SectionTitle>
		<Paragraph class="Default">The system administrator must regularly check the disk space on the system because a lack of disk space can cause application errors.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Remove temporary files</SectionTitle>
		<Paragraph class="Default"> 
                              ERP LN can create several temporary files that, after use, are no longer useful. To save disk space, the system administrator must remove the temporary files on a regular basis.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Create back-up files</SectionTitle>
		<Paragraph class="Default">To prevent a loss of data, the system administrator must create back-up files on a regular basis. The reason to make back-up files is so if a file is damaged, the original file can be retrieved from the back-up files.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Control user management</SectionTitle>
		<Paragraph class="Default">Before a user can work with ERP LN, the system administrator must first define the user data. To avoid the unauthorized use of programs, user authorizations are defined in roles that can be linked to the individual users.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Install updates</SectionTitle>
		<Paragraph class="Default">If ERP LN sends an update of the ERP LN software, the system administrator must install the update on the system as soon as possible.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Log changes in the system</SectionTitle>
		<Paragraph class="Default">The system administrator must log the changes to the system. An administrator can change many aspects in the system, for example, the printer definition files. The logged information can be useful for problem solving.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Perform all initialization procedures</SectionTitle>
		<List><ListIntro>The system administrator must know all initialization procedures, for example:</ListIntro>
			<ListItem>How to create a new company number</ListItem>
			<ListItem>How to enter data for a new company number</ListItem>
			<ListItem>How to copy an existing company number to a company number For details on this procedure, refer to <Link href="/baanerp/tt/onlinemanual/100140" role="manual">To copy a multicompany structure</Link> in the “Enterprise Server” section in the Infor Web Help.</ListItem>
		</List>
	</GeneralSection>
	<GeneralSection><SectionTitle>Create and customize software</SectionTitle>
		<Paragraph class="Default">To optimize the use of ERP LN, the system administrator can create or customize various software components, for example, menus, forms, and reports.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Perform periodic application runs</SectionTitle>
		<Paragraph class="Default">Some application programs must run on a regular basis. The system administrator is responsible to run these programs, for example, to update statistics and to print and remove stock transactions.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Maintain the system log</SectionTitle>
		<Paragraph class="Default">Data about the system and the application is stored in a system log.</Paragraph>
		<List><ListIntro>The system data includes information about:</ListIntro>
			<ListItem>The application environment</ListItem>
			<ListItem>Any reorganization of tables</ListItem>
			<ListItem>The available free disk space</ListItem>
			<ListItem>The back-up schedule</ListItem>
			<ListItem>The user data reports</ListItem>
			<ListItem>The updates</ListItem>
			<ListItem>Changes in the system</ListItem>
			<ListItem>The error messages and solutions</ListItem>

	<GeneralSection><SectionTitle>Analyze problems</SectionTitle>
		<Paragraph class="Default">The system administrator must analyze any problems that occur during the usage of ERP LN.</Paragraph>
		<Paragraph class="Default">
                              ERP LN offers various logging features that are helpful for problem analysis, such as logging for database locking.</Paragraph>
		<GeneralSection><SectionTitle>Logging for database locking</SectionTitle>
			<Paragraph class="Default">
                                 ERP LN offers a logging mechanism to gather statistics on database locking. You can use the statistics to identify long waiting times, long locks, and retries, which cause performance problems.</Paragraph>
			<ProcedureList><ListIntro>To use this logging mechanism, complete the following steps:</ListIntro>
				<ListItem>To activate the logging, start the <GUIRef href="/baanerp/tt/aad/ttaad4153m000" role="session">Logging Parameters (ttaad4153m000)</GUIRef> session and specify the following information: <List><ListItem>A threshold, in milliseconds, for logging database lock actions.</ListItem>
						<ListItem>A file to store the locking statistics.</ListItem>
						<ListItem>A time frame in which the logging takes place.</ListItem>
					</List> After you specified the logging parameters, you must convert them to runtime.</ListItem>
				<ListItem>To analyze the logging statistics, use the <GUIRef href="/baanerp/tt/stp/ttstplocklog" role="session">Generate lock graph html output (ttstplocklog)</GUIRef> session. The session first generates a snapshot file, based on the locking log file(s). This file contains all, or a subset of, the log records. Then, the session generates an html report that displays the contents of this snapshot file.</ListItem>
			</ProcedureList>
			<Paragraph class="Default">For details, refer to the online help of the sessions mentioned.</Paragraph>
