2 Intrductin This white paper describes the architecture and highlights the value prpsitin f Oracle WebLgic Server n Oracle Database Appliance (ODA) virtual envirnment. The Oracle Database Appliance (ODA) is an Oracle engineered system, cnsisting f hardware and sftware, designed t simplify the deplyment, maintenance and supprt f high availability database and middle tier WebLgic slutins. The latest versin f ODA appliance Oracle Database Appliance Manager v2.7 and v2.8 - enables custmers t deply this simplified and affrdable database slutin in either a physical r a virtual envirnment. In the ODA physical envirnment, custmers can cntinue t deply a highly available Oracle Database n the physical hardware. Fr mre infrmatin n this deplyment, please refer t the Oracle Database Appliance White Paper. In the ODA virtual envirnment, custmers can deply Oracle Database, Oracle WebLgic Server and cnslidate their applicatin and database tier within the ODA appliance t further lwer their capital expenditure. This allws custmers t have an entire enterprise applicatin infrastructure deplyed within a single appliance. ODA virtual envirnment als ffers custmers a unique pay-as-yu-grw sftware licensing capability t the prvisined Oracle Database and WebLgic Server within the ODA appliance. This allws custmers t efficiently manage their sftware licensing csts while scaling their database and middle tier t fully utilize the prcessr cres available in the appliance. The primary purpse f this engineered system and the ODA virtualized platfrm is t be: Simple Reliable Affrdable This is an ideal appliance fr custmers wh value simplicity and wh seek t avid the cmplexity, csts, and risks in deplying a highly available database slutin. In additin, with ODA virtualized platfrm, custmers can prvisin a tw, fur r eight nde WebLgic cluster alng with a sftware lad balancer t frnt-end these clusters in an extremely simple fashin withut requiring special skills r HA expertise. 1

3 Simple t Implement, Manage, and Supprt Simple t Implement The hallmark f the Oracle Database Appliance is its simplicity: a single bx, with servers, strage and netwrking all engineered tgether as a cmplete system with n assembly r wiring required. T deply and use the Oracle Database Appliance, simply unpack it, plug in the pwer crd, plug in the netwrk cables, and run the Oracle Appliance Manager installatin t create a clustered, highly available database and WebLgic Server. Simple t Manage and Maintain Maintaining systems and keeping all the assciated sftware elements current with the latest patches is ften ne f the mst time cnsuming and errr-prne tasks administratrs are cnfrnted with. The Oracle Database Appliance and its specially engineered sftware enables ne buttn patching fr all the elements f the sftware stack firmware, perating system, clusterware, strage manager, and database sftware. The appliance simplifies strage management by autmatically detecting perfrmance and availability issues and perfrming crrective actins. Disks can be replaced withut administrative tasks, and shuld a strage device exhibit behavir that indicates it is beginning t fail and is impacting perfrmance, the appliance will ffline the disk and rebuild redundancy. If hardware fails r is abut t fail, the Autmated Service Request capability (phne hme) generates autmatic requisitins fr replacement cmpnents such as disks, pwer supplies, fans etc. When a prblem ccurs, Oracle Database Appliance gathers and packages all the relevant lgs t service the supprt request. Rather than requiring the DBA r System Administratr t manually search fr and cmpile all the lgs and system histry when issuing a Supprt Request, the Oracle Appliance Manager autmatically cllects and then cmpiles the relevant lgs and histry, allwing issues t be prcessed, analyzed and fixed much mre quickly. ODA Virtualized Platfrm Oracle empwers custmers t decide n the Oracle Database Appliance prvisin mdel ODA Physical r ODA Virtualized t best suite their needs. The ODA physical platfrm leverages the ODA Appliance Manager t deply a highly scalable database within the physical hardware in few steps.
