Opening an Encylopedia results in a hang at the Processing phase in Rational System Architect XT

Technote (troubleshooting)


Attempts to open an Encylopedia results in a hang at the Processing phase in IBM Rational Rational System Architect XT (SAXT).


You notice both:

  • SAXT does not advance after you select an Encyclopedia to open. The message "Processing..." displays continuously.

  • In your Web Server log file, for example "C:/inetpub/logs/LogFiles/W3SVC1/u_ex130628.log" the following message is seen:
    POST /saxt/Default.aspx - 80 XXX\Administrator ::1 Mozilla/5.0+(compatible;+MSIE+10.0;+Windows+NT+6.1;+WOW64;+Trident/6.0) 200 0 0 1015

    Note: XXX in the above message is the name of the computer running the web server. Then name will be different for you.
