Problem:

After installing MFA Server (v3.0), try to access the Web Admin page as described in the MFA Serer Admin Guide 2.2.11 but a blank page is always returned.  No error message.

Resolution:

The following parameters are important to web server functioning.

ADMIN_PORT=1504                --- TcpIp port for Web Server

WEB_ROOT=XDBLHAS.V301RLW.WEBROOT  <===example prefix

WWWS_MAXTASKS=2                --- # of TCBS for Web Server

ISPI_MAXTASKS=2                --- # of TCBS for Web Server ISPI pgms

There should be four data sets from the installation process that have the WEB_ROOT dsn prefix (the following are example data set names):

XDBLHAS.V301RLW.WEBROOT.CLASS      

XDBLHAS.V301RLW.WEBROOT.GIF        

XDBLHAS.V301RLW.WEBROOT.HTML       

XDBLHAS.V301RLW.WEBROOT.PUBLIC.HTML

These data sets contain the static web resources

If the WEB_ROOT parameter contains an invalid prefix, the browser request is received OK by the mainframe web server but it cannot find any data sets containing the web resources (pages, gifs, java classes).  Therefore, you end up with a blank page...DONE at the bottom.  There is no content that can be found by the web server to send back to the browser.  The server simply takes the WEB_ROOT value and appends the appropriate resource type name qualifier and tries to open and read the data set.

The WEB_ROOT name must be correct and the server must have access to those data sets.
