When running a SAS^® Stored Process using the SAS Stored Process Web Application on a Bea WebLogic server, slow performance might occur when loading the initial HTML window if the stored process contains a parameter with a large number of option values.

As an example, if a parameter contains 8,000 option values, the HTML window that displays the parameter might load slowly when the stored process is executed.

If you encounter this problem, the performance problem might be related to the XML parser that WebLogic is using when parsing the XML stream that is passed from the SAS^® Metadata Server to the SAS Stored Process Web Application. You can select another, probably faster XML parser to be used for Stored Process Web Application requests by following these steps.

1. Go to this directory:

     ...\Lev1\web\webapps\exploded\SASWebReportStudio.war\WEB-INF\lib\
   

   Copy the following three files:

     xalan.jar
     xercesImpl.jar
     xmlParserAPIs.jar
   

   Copy the above three files to:

   
     ...\Lev1\web\webapps\exploded\SASStoredProcess.war\WEB-INF\lib\
   

2. Modify the following file:

     ...\Lev1\web\webapps\exploded\SASStoredProcess.war\WEB-INF\weblogic.xml
   

   In the weblogic.xml file, modify the <container-descriptor> section to include the following text.

     <container-descriptor>
     <servlet-reload-check-secs>-1</servlet-reload-check-secs>
     <!-- prefer stp delivered xerces xml parser -->
     <prefer-web-inf-classes>true</prefer-web-inf-classes>
     </container-descriptor>
   

3. Using your WebLogic Server Console, redeploy the SASStoredProcess Web Application.

   Select \exploded\SASStoredProcess.war (and not the original "SASStoredProcess.war" file) to include the changes.
