2 Prerequisites for Enterprise Deployments 2-1 2 Prerequisites for Enterprise Deployments This chapter describes the prerequisites for the Oracle Identity Management Infrastructure enterprise deployment topologies. This chapter includes the following topics: ■ Section 2.1, Hardware Resource Planning ■ Section 2.2, Network Prerequisites ■ Section 2.3, WebLogic Domain Considerations ■ Section 2.4, Shared Storage and Recommended Directory Structure

2.1 Hardware Resource Planning

The minimum hardware requirements for the Enterprise Deployment on Linux operating systems are listed in Table 2–1 . The memory figures represent the memory required to install and run an Oracle Fusion Middleware server; however, for most production sites, you should configure at least 4 GB of physical memory. For detailed requirements, or for requirements for other platforms, see the Oracle Fusion Middleware Installation Guide for that platform. These are the typical hardware requirements. For each tier, carefully consider the load, throughput, response time and other requirements to plan the actual capacity required. The number of nodes, CPUs, and memory required can vary for each tier Table 2–1 Typical Hardware Requirements Server Processor Disk Memory TMP Directory Swap Database Hosts OIDDBHOSTn, OIDDBHOSTn, OAAMDBHOSTn 4 or more X Pentium 1.5 GHz or greater nXm n=Number of disks, at least 4 striped as one disk. m=Size of the disk minimum of 30 GB 6-16 GB Default Default WEBHOSTn 2 or more X Pentium 1.5 GHz or greater 10 GB 4 GB Default Default IDMHOSTn, OAMHOSTn, OIMHOSTn, OAAMHOSTn 2 or more X Pentium 1.5 GHz or greater 10 GB 6 GB Default Default OIDHOSTn, OVDHOSTn 2 or more X Pentium 1.5 GHz or greater 10 GB 4 GB Default Default 2-2 Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity Management based on the deployment profile.Production requirements may vary depending on applications and the number of users. The Enterprise Deployment configurations described in this guide use two servers for each tier to provide failover capability; however, this does not presume adequate computing resources for any application or user population. If the system workload increases such that performance is degraded, you can add servers to the configuration by repeating the instructions for the second server that is, WEBHOST2, IDMHOST2, OIDHOST2, OVDHOST2, OIDDBHOST2 to install and configure additional servers where needed.
