1 Will DatabaseAce harm my data's integrity?
Back to Top DatabaseAce cannot harm your data's referential integrity provided that the database's constraints are represented and configured properly in its model; the DatabaseAce Maker does this automatically.

Referential integrity however is not the same as operational integrity. If the database is being used by an external system, it may be possible to mistakenly alter the data in a way that would confuse the external system.

In situations where this is a potential problem, administrators are encouraged to designate some or all tables as read-only for non-experienced users to prevent inappropriate changes.
2 Can I receive a new license if my server suffers a hardware failure or if I accidently license the wrong computer?
Back to Top Replacement licenses are issued free of charge for customers with current support contracts in place.

One year's support is included free with the initial purchase of DatabaseAce.
3 Can I deploy DatabaseAce using a standard web hosting account?
Back to Top Yes provided that your web host's PHP instance meets the following requirements:

  • PHP 5.1 or later
  • Suhosin Extension installed
  • IonCube Loader Extension installed
  • OpenSSL Extension installed
    		•
    4 Why has DatabaseAce stopped responding correctly after I edited one of its XML files (skin, locale, configuration, etc)?
    Back to Top If a single XML tag is given the same argument more than once, it will prevent the rest of the XML file from being parsed correctly.

    This can result in anything from missing page elements (like login buttons or menus) to a total lack of response (a white screen) depending on where it happens.

    Check the XML file to ensure no tags have received duplicate properties.

    The tag <tag property="value1"> will work but

    <tag property="value1" property="value2"> will not.
    5 After restarting my Windows DatabaseAce server, I either can't log in or, when I do log in, see an error that says 'Access to the table is denied'
    Back to Top From time to time, the database may fail to start automatically after restarting a Windows server. To correct this problem, open the All Programs list from the server's Start menu, then select DatabaseAce DatabaseAce -> Services -> Start Database
    6 I can log in to my Unix-based DatabaseAce instance successfully, but when I subsequently try to click on any link, it kicks me out and I am returned to the login screen
    Back to Top This generally indicates that the web server lacks write permission to DatabaseAce's repository directory. This directory is located in the REIGNN/repository folder (relative to DatabaseAce's installation folder). The system account under which your web server is running must have write access to this directory and all of its child directories in order for sessions to be stored correctly.
    7 The page looks disjointed and lacks fonts and other expected visual details
    Back to Top This may indicate that the web server lacks write permission to the session directory inside the program's web-readable "dock" directory (which is htdocs/databaseace by default). The system account under which your web server is running must have write access to this directory in order for pages to appear correctly.
    8 I am using MySQL to host the DatabaseAce administration database and cannot connect to other databases hosted on the same MySQL server
    Back to Top When using MySQL to host DatabaseAce's backend administration database, it is not currently possible to connect with other databases that are hosted on the same server as the admin database. Recommended workaround is to host DatabaseAce's administration database on a different server.
    9 While using HTTP authentication on my web server, I cannot view charts, use the REIGNN Maker or run tests on external servers.
    Back to Top Certain functions within DatabaseAce require that it post HTTP requests to pages on its own web server. These internal requests are blocked by the use of HTTP authentication. Therefore, to enjoy full use of DatabaseAce's capabilities, it is recommended that it not be run under HTTP authentication. DatabaseAce has its own set of authentication features, making HTTP authentication redundant.
    10 When serving DatabaseAce through IIS, I can reach the login screen but cannot log in.
    Back to Top If the URL you are using to connect with DatabaseAce does not end with 'index.php', add /index.php to the end of the URL and try again.
