---++ Standard topologies overview

This page describes the Alternate SSE Deployment Topologies for versions 3.x and 4.x. Refer to [[StandardTopologiesOverview][Standard deployment topologies overview]] for high-level description of the standard topologies, how they are categorized and their key characteristics. 

These alternative deployment topologies for the Rational solution for systems and software engineering (SSE) are a subset of the standard SSE deployment topologies. For the rest of the standard topologies, see [[RecommendedSSEDeploymentTopologies][Recommended SSE deployment topologies]]. 

---++ (SSE-E3) Enterprise distributed Red Hat Enterprise Linux (RHEL) with DB2 and DOORS/DWA

This enterprise topology uses Linux for the server operating systems. It includes DOORS/DWA as the RM application. The applications are distributed across separate servers and WAS instances. A reverse proxy is used to ensure public URI stability. DB2 is used for the databases and is hosted on a separate server. Finally, licenses are served by a floating license server and Tivoli Directory Server provides the LDAP based user management, for all but DOORS/DWA, which uses Windows Active Directory Server.

<b>Note</b>: There have been incidences of the DWA Interops core dumping when processing an RQM Reconcile operation on Linux.  To avoid this issue the DWA Interops should be run on a Windows server.  This issue is currently under investigation in APAR PI08809 (http://www.ibm.com/support/docview.wss?uid=swg1PI07809)
