Saving a large social network takes a long time on SAS® Social Network Analysis Server


On SAS Social Network Analysis Server, you can save a network by clicking the Save button in the social-network diagram of a SAS® Social Network Analysis page. However, the process of saving might be slow.

When this issue occurs, you do not receive any error, warning, or note messages to indicate that a problem occurred.

To resolve the issue, follow these steps:

  1. Open the web.xml file that is located in the SAS-configuration-directory\LevN\Web\WebAppServer\SASServer8_1\sas_webapps\sas.sso.snaserver.war\WEB-INF directory.

  2. Locate this section of code:
    <filter-name>SanitizingRequestFilter</filter-name>
    <filter-class>org.springframework.web.filter
  3. After that section of code, add the following code if it is not already present. If this code is present, then verify (or edit, as necessary) the code so that it looks exactly like the code shown below.
    <init-param> <param-name>allowedPostNames</param-name> <param-value>snaSheet,links,nodes,groups,customMeasures</param-value> </init-param>
  4. Save the file and restart SASServer8.
