SCALABLE ENTERPRISEConfiguring the hardware and softwareTo test migration from Sun to Dell, the Dell team installed and configureda Sun Fire V440 server and a Dell PowerEdge 6650 server. Asshown in Figure 1, both servers were configured with four processorsand 16 GB of RAM as well as with several internal drives andon-board network interface cards (NICs).A Dell/EMC CX600 storage array provided the storage for thedatabase and was connected to both Sun and Dell servers via astorage area network (SAN). Each server was assigned three 10-diskRAID-10 logical storage units (LUNs) to be used for data and two2-disk RAID-1 LUNs to be used for logs. An additional 5-disk RAID-5LUN was also assigned to each server for data staging during migrationand initial database creation.Both servers were configured with current operating systems andOracle Database 10g. Oracle’s Universal Installer tool can be used onboth Sun and Dell servers to install Oracle Database 10g, g enablingadministrators to select the same options during installation on differentplatforms.Sun Fire V440 Dell PowerEdge 6650Operating system Solaris 9 12/03 Microsoft Windows Server 2003,Enterprise Edition, or Red HatEnterprise Linux AS 3CPUFour UltraSPARC IIIi processors Four Intel Xeon processors MPat 1.28 GHz and with 1 MB at 3.0 GHz and with 4 MBof L2 cacheof L3 cacheMemory 16 GB 16 GB (16 × 1 GB dual in-linememory modules, or DIMMs)Internal disks** Four 73 GB 10,000 rpm Four 73 GB 10,000 rpmUltra320 SCSIUltra320 SCSINICs Two 10/100/1000 Mbps Two 10/100/1000* Mbps(internal)(internal)Disk controller On-board SCSI PowerEdge Expandable RAIDController 3, Dual Channel(PERC 3/DC)Fibre Channel hostbus adapterTwo QLogic QLA2340 Two QLogic QLA2340Fibre Channel 34 GB to 73 GB 10,000 rpm 34 GB to 73 GB 10,000 rpmstorage disks on Dell/EMC CX600 disks on Dell/EMC CX600*This term does not connote an actual operating speed of 1 Gbps.

Sun Fire V440 and Dell PowerEdge 6650 server configurationsSolaris 9 12/03 was installed on the Sun Fire V440 server usingSun Factory JumpStart. Two installations were performed on thesame PowerEdge 6650 server to test two operating systems: Red HatEnterprise Linux AS 3 and Microsoft Windows Server 2003, EnterpriseEdition. Both were installed using Dell OpenManage Server Assistantsoftware. Oracle Database 10gg installation guides and release notes forthe respective platforms were then used to verify that the correct softwarelevels were used and that the necessary settings were changed.The new Automatic Storage Manager (ASM) feature of OracleDatabase 10ggwas used during the creation of the initial databaseon both Sun and Dell servers to improve the performance andmanagement of the data files. The three large RAID-10 LUNs wereassigned in ASM to be part of a single file group for the data files,while each of the RAID-1 LUNs was assigned to a separate ASMfile group for logs. An initial database instance was created on eachof the servers using the OracleDatabase Creation Assistant.ASM was used for the storageon both instances.The 100 GB DVD store (DS)database schema was loadedonto the Sun system. It comprisedfour main tables and oneother table (see Figure 2).The Customers table wasprepopulated with 200 millioncustomers. The Orders table was prepopulated with 10 million ordersper month for nine months, the Orderlines table was prepopulatedwith an average of five items per order, and the Products tablecontained 1 million DVD titles. In addition, the Categories tablelisted 16 DVD categories.Using Data Pump to prepare the migrationData Pump export and Data Pump import are additional utilitiesin Oracle Database 10g, g but have a similar look-and-feel to theoriginal export and import utilities. Data Pump export is a utilityfor unloading data and metadata from the database into a set ofoperating system files called dump file sets. A dump file set canbe moved to another system and loaded by the Data Pump importutility. Data Pump import is used to load the metadata and datastored in an export dump file set into the database on the targetsystem.
