Error starting sa2001
Possible causes
The impersonation account could not start the service
1 Browse to the installation folder of System Architect XT:
C:\Program Files\UNICOM Systems\System Architect Suite\System Architect
2 Manually start the sa2001.exe file.
The impersonation account does not have the correct permissions for the SA2001.Lexus file
1 Start Administrative Tools > Component Services > Computers > My Computer > DCOM Config.
2 Right-click SA2001.Lexus, click Properties, and then click the Security tab.
3 Under Launch and Activation Permissions, click Customize, and then click Edit.
4 Add the impersonation account and give it full control. In this example, the account is named DOMAIN\saxtuser, but the account varies by site.
For license issues, look at the log from the license server
It can contain something such as:
Invalid license key (inconsistent authentication code) 17:33:24 (ibmratl) ==?FEATURE SA-XT-Read-Write
This occurs when users try to modify the license.dat file, which cannot be done. Feature information such as expiration date and number of users for that feature is encrypted, and attempting to change them results in the error. To resolve this issue, generate and use a new license.
Microsoft IIS configuration issues
Fix Microsoft IIS configuration issues as follows:
1 Remove the virtual SAXT folder from Microsoft IIS.
2 Stop Microsoft IIS.
3 Create the virtual SAXT folder again, pointing to the same SAXT installation folder, and the same SAXTApplicationPool for the Application Pool property.
4 Select SAXT in Microsoft IIS.
5 Go to Authentication and perform these actions:
Enable Windows Authentication.
Enable ASP.NET Impersonation.
Disable Anonymous Authentication.
Disable Basic Authentication.
6 Restart Microsoft IIS and restart the server machine.
If there is a timeout error, do this:
7 Add the following items in the web.config file:
<sessionStatemode="InProc"stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1; Trusted_Connection=yes" cookieless="false" timeout="20"/>
and
<httpRuntime executionTimeout="3600"/>
8 Check for permissions.
9 Login in Updater mode.
Other cause
Browse to the System Architect installation folder:
C:\Program Files\UNICOM Systems\System Architect Suite\System Architect
Open the SA2001.log file in a text editor such as Notepad. This should contain an entry with an error message that was received from the application. If there is nothing there, check for errors in the system’s Event Viewer, normally accessible from Control Panel > Administrative Tools.
