---++ Introduction
This article provides the Rational Team Concert 4.0.4 sizing report specifically for z/OS, which is part of findings for [[https://jazz.net/wiki/bin/view/Deployment/RTCSystemZPerformanceTesting][RTC for System z performance testing]]. We are adopting the Rational Team Concert test harness to simulate actual client workload and validate our scalability requirements. Read the [[https://jazz.net/wiki/bin/view/Deployment/RationalTeamConcert404PerformanceReport][Collaborative Lifecycle Management performance report: RTC 4.0.4 release]] first for more information about the Rational Team Concert test harness.

Since version 4.0 was released, we have focused on performance testing using [[https://jazz.net/wiki/bin/view/Deployment/StandardTopologiesOverview][standard topologies]]. For more information related to the system requirements, see [[https://jazz.net/wiki/bin/view/Deployment/CLMSystemRequirements][System Requirements for Collaborative Lifecycle Management]].

---++ Topology
This sizing report is specifically for:

   * Single-Tier Mode: Linux for System z standalone topology, which deploys the application server on Linux for System z and DB2 on Linux for System z

   * Dual-Tier Mode: [[https://jazz.net/wiki/bin/view/Deployment/AlternativeCLMDeploymentTopologies#CLM_E5_Enterprise_zOS_Linux_on_S][standard topology - E5]], which deploys the application server on Linux for System z and DB2 on z/OS

---++ Findings

---+++ Small-scale enterprise deployment 
For this sizing report, a small-scale deployment is a configuration of between 100 and 700 users on either a single-tier or a double-tier setup. For a single-tier setup, the application server and database are running on the same LPAR. For dual-tier setup, the application server and database are running on different LPARs.

   * The following table lists the system configurations we used for a small-scale single-tier setup scenario:

---+++ Large-scale enterprise deployment 
For this sizing report, a large-scale deployment is a configuration of between 700 and 2000 users on either a single-tier or a double-tier setup. For a single-tier setup, the application server and database are running on the same LPAR. For dual-tier setup, the application server and database are running on different LPARs.
