customizing a logon frontend to identify what app server is being used.

robm — Wed, 17 Jun 2015 21:37:57 GMT

was trying to use this link to customize a page

SAS(R) 9.4 Intelligence Platform: Middle-Tier Administration Guide, Second Edition

what i would like to do is use some JSP code to identify what WebAppServer and what MetaDataServer I am using

to this end i modifed the D:\SASHome\SASWebInfrastructurePlatform\9.4\Static\wars\sas.svcs.logon\WEB-INF\view\jsp\default\ui\logon_custom.jsp

hoping that the environment variables might reveal something but after a build of the wip service and a deployment on all 3 nodes I still see nothing on the

logon page . i went in prior to the deployment and enable the customization in SASS Manager , I assume this just flags to include the logon_custom.jsp.

any ideas how I can get this to work I still have a login page with no additional information

<%--

This JSP file is included as part of the logon.jsp if a site

has enabled the custom logon page message policy. The tags

below are provided as a simple convenience for those sites

that want to simply provide an embedded text message. These

tags can be modified or removed if additional customization

is required.

--%>

<p>

java.util.Enumeration e = System.getProperties().propertyNames();

while( e.hasMoreElements() ){

String prop = (String)e.nextElement();

out.print(prop);

out.print(" = ");

out.print( System.getProperty(prop) );

out.print("<br>");

}

</p>

Hi robm,

Found your question interesting.

What is it you are utlimately trying to achieve i.e. why do you need to identify what app server is being used? Are you trying to determine the level of load balancing across 2 or more instances of the same web app server?

Cheers, Simon

to some extent yes that was the goal . In the interrum I ran across ways to embedd JSP and jquery into the logon_custom.jsp and get information and do some cooll coding. Our experiment with a cluster was a utter failure due to a plan file that did mnot work ...we had to pay the SAS consultant more to actually create one again . Anyway at that point we said ^&^% it and went with stand alone servers.

Hi robm,

Sounds like you have come to a conclusion but for future reference there are some built in-tools you can use with SAS 9.4:

SAS Web Administration Console;
Load Balancer interface;

See: SAS 9.4 Intelligence Platform: Middle-Tier Administration Guide, Third Edition

SAS Web Administration Console:　

monitoring information about users who are currently logged on to SAS web applications;
viewing audit reports that show user logon and logoff activity and failed logon attempts
performing server maintenance, as a part of system maintenance
updating the Job Execution Service configuration on page 78
managing notification templates and letterheads
managing authorization, including Web Infrastructure Platform roles and privileges and web-layer permissions
viewing the current configuration for web applications that have been deployed at your site

Load Balancer interface:

sessions are assigned to a given instance of a SAS Web Application Server;
Allows an administrator to drain sessions to prevent new users logging on;

well not to get what metadata server I was using, however

D:\SASConfig\Lev1\Web\WebAppServer\SASServer1_1\sas_webapps\sas.svcs.logon.war\WEB-INF\view\jsp\default\ui

if you have custom logon and custom logout enabled

Application management>SAS Aplication Infrastructure>Properties>Settings

say yes to Display Custome logon message

then in logon_customer.jsp you can write some JSP code to spit out env vars

<%
   java.util.Enumeration e = System.getProperties().propertyNames();
   while( e.hasMoreElements() ){
   	String prop = (String)e.nextElement();
   	out.print(prop);
   	out.print(" = ");
   	out.print( System.getProperty(prop) );
   	out.print("<br>");
   }
%>

you can t include stuff like

<%@ page import="java.util.*" %>

as well you can insert jQUERY to do things like in this case redirect a bad URL someone has cached:

we have users that have links from 9.3ebi on there desktop instead of an error this redirects them to the login page and they can go find their new link
