4 Intrductin This white paper prvides step-by-step guidelines fr deplying an Exadata DB system n Oracle Clud Infrastructure. This paper utlines sme best practices; it is nt intended t be used as a full reference guide fr implementing Exadata. This dcument assumes that yu have a basic understanding f varius cmpnents f Oracle Clud Infrastructure: Fundamentals f Oracle Clud Infrastructure Oracle Clud Infrastructure Netwrking, specifically virtual clud netwrks (VCNs), subnets, security lists, and rute tables Oracle Clud Infrastructure Identity Access Management (IAM) Overview f Exadata n Oracle Clud Infrastructure An Exadata DB system cnsists f a quarter rack, half rack, r full rack f cmpute ndes and strage servers, tied tgether by a high-speed, lw-latency InfiniBand netwrk and intelligent Exadata sftware. Yu can cnfigure autmatic backups, ptimize fr different wrklads, and scale up the system t meet increased demands. The cmpute ndes are each cnfigured with a virtual machine (VM). Yu have rt privilege fr the cmpute nde VMs, s yu can lad and run additinal sftware n them. Hwever, yu d nt have administrative access t the Exadata infrastructure cmpnents, such as the physical cmpute nde hardware, netwrk switches, pwer distributin units (PDUs), integrated lights-ut management (ILOM) interfaces, r the Exadata Strage Servers, which are all administered by Oracle. Yu have full administrative privileges fr yur databases, and yu can cnnect t yur databases by using Oracle Net Services frm utside Oracle Clud Infrastructure. Yu are respnsible fr database administratin tasks such as creating tablespaces and managing database users. Yu can als custmize the default autmated maintenance setup, including backups, and yu have full cntrl f the recvery prcess in the event f a database failure. Oracle Clud Infrastructure ffers tw versins f Exadata, X6 and X7, and each versin cmes with three shapes. Fr details abut these shapes, see the System Cnfiguratin sectin f the Exadata DB Systems tpic in the Database service dcumentatin. Nte: Actual usable strage fr the DATA disk grup depends n the backup ptin that yu chse when yu launch an Exadata DB system. See the Exadata DB system dcumentatin fr details. 4 DEPLOYING AN EXADATA DB SYSTEM ON ORACLE CLOUD INFRASTRUCTURE

5 Supprted Database Editin and Versins Exadata DB systems require Enterprise Editin - Extreme Perfrmance. This editin prvides all the features f Oracle Database Enterprise Editin, plus all the database enterprise management packs and all the Enterprise Editin ptins, such as Oracle Database In-Memry and Oracle Real Applicatin Clusters (RAC). Fr a list f the supprted sftware releases, see Supprted Database Editin and Versins in the Database service dcumentatin. Access Requirements fr Deplying Exadata T launch Exadata in Oracle Clud Infrastructure, yu must be given the required access via an IAM plicy. The fllwing is a sample IAM plicy that prvides this access t grup DBAdmins at tenancy level. T reduce the scpe f access t just the database systems in a particular cmpartment, specify that cmpartment instead f the tenancy. Allw grup DBAdmins t manage database-family in tenancy Yu will als require the public key that yu plan t use t cnnect t DB system via SSH. Steps t Launch an Exadata DB System n Oracle Clud Infrastructure This sectin prvides the steps t create the required netwrking cmpnents and launch an Exadata DB system in Oracle Clud Infrastructure. References t the Oracle Clud Infrastructure Netwrking and Database services dcumentatin are prvide fr detailed steps. Step 1: Create a VCN 1. Sign in t the Oracle Clud Infrastructure Cnsle. 2. Create a VCN, fllwing the steps in T create a clud netwrk. Fr this example, enter the fllwing values in the Create Virtual Clud Netwrk dialg bx: Fr Name, enter ExaVCN. Select Create Virtual Clud Netwrk Only. 5 DEPLOYING AN EXADATA DB SYSTEM ON ORACLE CLOUD INFRASTRUCTURE

6 Fr CIDR Blck, enter /16. Nte: We recmmend using ne f the private IP address ranges specified in RFC 1918 ( /8, /12, and /16). Hwever, yu can use a publicly rutable range. The VCN s CIDR must nt verlap with yur n-premises netwrk r anther VCN yu peer with. Fr details, see Access t Other VCNs: Peering. Select the Use DNS Hstnames in This VCN check bx. Fr DNS Label, enter exavcn. After the VCN is created, it appears in Cnsle. 6 DEPLOYING AN EXADATA DB SYSTEM ON ORACLE CLOUD INFRASTRUCTURE

7 Step 2: Create an Internet Gateway An internet gateway is a virtual ruter that cnnects the edge f the clud netwrk with the internet. Traffic that riginates in yur VCN and is destined fr a public IP address utside the VCN ges thrugh the internet gateway. 1. In the Cnsle, click the name f the VCN that yu created. 2. Create an internet gateway, fllwing the steps in T create an internet gateway. Fr this example, in the Create Internet Gateway dialg bx, enter ExaIG fr the name. Step 3: Create a Service Gateway A service gateway lets resurces in yur VCN access public Oracle Clud Infrastructure services such as Object Strage withut using an internet gateway r NAT. Any traffic frm yur VCN that is destined fr ne f the supprted public services uses the instance's private IP address fr ruting, travels ver the Oracle Clud Infrastructure netwrk fabric, and never traverses the internet. Here yu create a service gateway and then use it in yur backup rute table s that Exadata backup can travel t Object Strage ver the Oracle Clud Infrastructure netwrk fabric. 1. In the Cnsle, click the name f the VCN that yu created. 2. Create a service gateway, fllwing the steps in Task 1: Create the service gateway. Fr this example, enter the fllwing values in the Create Service Gateway dialg bx: Fr Name, enter DemSG. 7 DEPLOYING AN EXADATA DB SYSTEM ON ORACLE CLOUD INFRASTRUCTURE

8 Fr Services, select OCI LHR Object Strage. Step 4: Create Rute Tables Yur clud netwrk uses virtual rute tables t send traffic ut f the VCN (fr example, t the internet r t yur n-premises netwrk). These virtual rute tables have rules that lk and act like traditinal netwrk rute rules that yu might already be familiar with. Each rule specifies a destinatin CIDR blck and the target (the next hp) fr any traffic that matches that CIDR. Fr Exadata, yu create tw rute tables, fr client traffic and backup traffic. 1. In the Cnsle, click the name f the VCN that yu created. 2. Create a rute table fr the client traffic, fllwing the steps in T create a rute table. Fr the client rute table, enter the fllwing values in the Create Rute Table dialg bx: Fr Name, enter Client_RT. In the Rute Rules sectin: Target Type: Internet Gateway Destinatin CIDR Blck: /0 Cmpartment Name: The cmpartment where the internet gateway is lcated. Target Internet Gateway: The internet gateway that yu created in Step 2 (in this example, ExaIG). 8 DEPLOYING AN EXADATA DB SYSTEM ON ORACLE CLOUD INFRASTRUCTURE

9 3. Create a rute table fr the backup traffic, fllwing the steps in T create a rute table. Fr the backup rute table, enter the fllwing values in the Create Rute Table dialg bx: Fr Name, enter Backup_RT. In the Rute Rules sectin: Target Type: Service Gateway Destinatin Service: OCI LHR Object Strage Cmpartment Name: The cmpartment where the service gateway is lcated. Target Service Gateway: The service gateway that yu created in Step 3 (in this example, DemSG). 9 DEPLOYING AN EXADATA DB SYSTEM ON ORACLE CLOUD INFRASTRUCTURE

10 Step 5: Create Security Lists A security list prvides a virtual firewall fr an instance, with ingress and egress rules that specify the types f traffic allwed in and ut. Each security list is enfrced at the instance level. Hwever, yu cnfigure yur security lists at the subnet level, which means that all instances in a given subnet are subject t the same set f rules. Each subnet can have a maximum f five security lists attached t it. After a subnet is created, security lists can t be added r deleted. Hwever, yu can always add mre ingress and egress rules t a security list. Exadata n Oracle Clud Infrastructure requires tw separate VCN subnets: a client subnet fr user data and a backup subnet fr backup traffic (instructins fr creating these subnets are in Step 7). In this step, yu create the fllwing nine security lists t be used with the subnets. Althugh yu dn t need all nine security lists right away, we recmmend attaching the maximum number f allwed security lists t a subnet because lists can t be added t a subnet afterwards. NdeTraffic: Fr cmmunicatin between Exadata ndes, and TCP and ICMP traffic acrss the client and backup subnets. This security list is shared with bth the client and backup subnet. 10 DEPLOYING AN EXADATA DB SYSTEM ON ORACLE CLOUD INFRASTRUCTURE

11 SSH_Traffic: Fr SSH traffic. SQLNet: Fr SQL Net traffic. Client1: Fr client traffic. Client2: Fr client traffic. DB_Backup1: Backup traffic t Object Strage. DB_Backup2: Backup traffic t Object Strage. Flex1: Flex security list fr future use. Flex2: Flex security list fr future use. Nte: We d nt recmmend using the default security list that is created when yu create the VCN. If yu add rules t the default security list t pen SQLNet traffic, these rules will be applied t every subnet t which the default security list is attached. Create nine empty security lists, using the preceding names fr the lists. In a later sectin, yu will add the ingress and egress rules t the security lists. 1. In the Cnsle, click the name f the VCN that yu created. 2. Create nine security lists, fllwing the steps in T create a new security list. Fr this example, enter the fllwing values in the Create Security List dialg bx: Enter a name fr the security list. See the preceding list fr the names t use. Delete the default entries fr the ingress and egress rules. The fllwing figure shws an example f the values t enter fr the NdeTraffic security list. 11 DEPLOYING AN EXADATA DB SYSTEM ON ORACLE CLOUD INFRASTRUCTURE

12 Step 6: Create DHCP Optins Yur VCN uses DHCP ptins t autmatically prvide cnfiguratin infrmatin t the instances when they bt up. Each VCN cmes with a default set f DHCP ptins with initial values that yu can change. In this step, yu create a separate DHCP ptin fr Exadata. 1. In the Cnsle, click the name f the VCN that yu created. 2. Create a new set f DHCP ptins, fllwing the steps in T create a new set f DHCP ptins. Fr this example, enter the fllwing values in the Create DHCP Optins dialg bx: Fr Name, enter ExaDHCP. Fr DNS Type, select Internet and VCN Reslver. Yu can leave the Search Dmain bx blank r prvide a value (fr example, raclevcn.cm). 12 DEPLOYING AN EXADATA DB SYSTEM ON ORACLE CLOUD INFRASTRUCTURE

13 Step 7: Create Subnets A subnet is a subdivisin f a VCN. Each subnet in a VCN exists in a single availability dmain and cnsists f a cntiguus range f IP addresses that d nt verlap with ther subnets in the clud netwrk. Fr mre infrmatin abut VCN and subnets, see Wrking with VCNs and Subnets. Fllw these steps t create the client and backup subnet. 1. In the Cnsle, click the name f the VCN that yu created. 2. In the Resurces sectin, click Subnets. 3. Click Create Subnet. 4. In the Create Subnet dialg bx, enter the fllwing values t create the client subnet: Enter a name fr the subnet (in this example, Client_Subnet_AD1). Chse the availability dmain where yu plan t launch the Exadata DB system. Enter the CIDR blck fr the subnet (in this example, /24). Chse the rute table that yu created fr the client traffic (in this example, Client_RT). 13 DEPLOYING AN EXADATA DB SYSTEM ON ORACLE CLOUD INFRASTRUCTURE
