<p class="Paragraph">Use this dialog to create a new <help:link Id="66189" xmlns:help="http://openoffice.org/2000/help">Adabas database</help:link>.<a name="ende"/></p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">This is where you enter the name of the database in Adabas.</help:help-text> Following confirmation of the dialog this name is transferred to the<span class="T1">Data source URL</span> field.</p>
<p class="Head2">User settings</p>
<p class="Paragraph">Enter the user settings here. <help:productname xmlns:help="http://openoffice.org/2000/help">%PRODUCTNAME</help:productname> has already filled in the fields with the default settings.</p>
<p class="Paragraph"><help:help-text value="hide" xmlns:help="http://openoffice.org/2000/help">Enter the name of the database Administrator in this field.</help:help-text> When an Adabas database is being created for the first time, you must enter at least one Administrator name and a password. The Administrator is also the first user. The Adabas version supplied with <help:productname xmlns:help="http://openoffice.org/2000/help">%PRODUCTNAME</help:productname> allows three users simultaneously. You will only see this field if you have called the dialog via <span class="T1">New Data Source</span>.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">The control user has the right to modify some parameters of the database. Normally, the default settings for name and password of the control user remain unchanged.</help:help-text> The control user exists regardless of the 3-user limitation.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">The user Domain is internally used by Adabas. Normally, the default settings for the name and password remain unchanged.</help:help-text> The Domain user exists regardless of the 3-user limit. You can only see this field, if you've called the dialog via the <span class="T1">New Data Source...</span> button.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Do not forget to enter a password for the administrator. This password will also be used for the Control user and Domain user.</help:help-text> These passwords can also differ from one another.</p>
<p class="Head2">Database settings</p>
<p class="Paragraph">Enter the database settings here. <help:productname xmlns:help="http://openoffice.org/2000/help">%PRODUCTNAME</help:productname> has already filled in most fields with the appropriate default settings.</p>
<p class="Paragraph">DEVSPACEs are drives containing parts of the Serverdb. Adabas recommends to store each of the DEVSPACEs on another disk to improve performance.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Enter the destination of the Devspace system.</help:help-text> Among other things, the configuration data will be managed in this Devspace. The size of the Devspace system depends on the size of the database.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Enter the location of the transaction log file.</help:help-text> All modifications made to the data base will be recorded in Log and overwritten when the transaction is over. The Log transaction is used for the transaction's rollback and will be cyclically written. Its size should be enough for including all modifications of all open transactions.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Enter the location of the Data Devspace here.</help:help-text> The user data (tables, indexes) and the SQL catalog (Schema info) will be stored in the Data Devspaces. The data contained in one table will be evenly distributed on all Data Devspaces. The disk space defined by all Data Devspaces shows the size of the database.</p>
<p class="Paragraph">The Data Devspace is limited to 100MB depending on the database in the <help:productname xmlns:help="http://openoffice.org/2000/help">%PRODUCTNAME</help:productname> Adabas version. If you need a higher capacity, please refer to the Adabas producer (Software AG, www.adabas.com).</p>
<p class="Paragraph">If Data Devspaces is used in its full capacity the database operation will be terminated and Adabas executes an emergency shutdown. The database will be then automatically increased (up to 100 MB) and restarted again. All saved data will not be lost.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">This is where you open a dialog for saving the Adabas system file for the current database. Select a directory and enter the name.</help:help-text></p>

<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Select the size of the database in megabytes here.</help:help-text> The size is limited to 100 MB in the <help:productname xmlns:help="http://openoffice.org/2000/help">%PRODUCTNAME</help:productname> Adabas version.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Select the data buffer size (data cache) in megabytes here. </help:help-text> This cache keeps the Pages of the Data Devspaces, which were last accessed either in reading or writing. The Data Cache will be simultaneously used by all active users. The hit rate or in other words, the relation between the successful and unsuccessful accesses to the Data Cache is of decisive importance for the performance. A successful access means that the needed data was already present in the Data Cache.</p>
