Modifying or creating alias for /irj path

[Former Member]

Our current architecture uses a reverse proxy in order to mask the hostname of the enterprise portal, bi-portal and other systems. The problem we are having is that the enterprise portal and bi-portal use the same paths to it's content which makes it impossible for the proxy to distinguish between the two. For example, the /irj/portalapps/ directory is present on both of them and when a call is made to proxyhostname.com/irj/portalapps, the proxy always redirects to the enterprise portal.

Is it possible to modify the /irj path or create an alias for the /irj path in the Portal? For example, make the BI-portal use /irj-bi or /bi/irj instead.

Hi Christian,

If you are having a seperate Portal for BI, try to have different domain names registered for both the Portals based on the IP in the DNS. By doing this you can call the /portalapps of the required server directly.

If alias is required to be created, then you can create a Application Alias which is an alternative name for a J2EE Web application running on the J2EE Engine in Visual Admin ( In Cluster ->Dispatcher ->services )

Hello Christian,

you could try to remove the irj/portal-alias from the url of the portal.

Perhaps this might help.

Please check the following Wiki-Page for more informations --> Change Portal URL

Another option is to create a new HTTP Alias from scratch.

You can find some more informations in the SAP Library --> HTTP Alias

Thank you for the suggestions! Changing the application URL would probably do the trick but since we might have multiple applications in the future I think the HTTP Alias would be better suited. I believe it is just what we need so I will do some tests with it and see how it works.

Hi -

I am trying to do the exact thing in my environment. Please let me know if it works for you. Thank you.

Hi,

Ok, we have now setup the alias and it is working to some degree.

What we did was that we created an HTTP Alias in Visual Administrator (Server --> Services --> HTTP Provider --> Runtime --> Alias) where the alias was irj-ep and the path was /usr/sap/<SID>/JC22/j2ee/cluster/server0/apps/sap.com/irj/servlet_jsp/irj/root (replacing <SID> with system ID ofc).

When accessing for example http://portalserver/irj-ep/portalapps/com.sap.portal.runtime.logon/js/basic.js we got the same results as when accesing http://portalserver/irj/portalapps/com.sap.portal.runtime.logon/js/basic.js which was positive. However when trying to access http://portalserver/irj-ep/portal we got a 404 Not Found error. The regular URL http://portalserver/irj/portal is working fine.

Any ideas why this could be occuring?

Thanks

Hello Christian,

today I've also tried to create a new HTTP Alias like described in the SAP Library for the Logon Page.

Unfortunately I'm also running into the problem you've already stated.

At the moment I don't have much time to test it any further.

But perhaps the following information are helpful and you get it working:

1. In VisualAdmin please check "Server -> Services -> Web Container -> sap.com/irj -> irj -> Button: View -> Register: Mapping"

2. The file "\usr\sap\<SID>\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\web.xml"

There you can also set up some Mapping configuration for the SAP system.

Perhaps you'll find a solution for the problem.

Hi Norman,

We have experimented some with mappings and tested the following mappings without any luck:

Servlet: prt

URL Pattern: /irj-ep/*

and

Servlet: gateway

URL Pattern: /irj-ep/*

Looking at the web.xml I've noticed that the portal_context_root is set to /irj which could be causing the problem. Still unsure on how to fix it though without modifying the existing one..

Best regards,

Christian

Hi Christian,

Do you get the solution about this problem?
