6 Chapter 1: Executive Summary Business challenge/value Solution overview While many organizations have successfully introduced virtualization as a core technology within their data centers, the benefits have largely been restricted to the IT infrastructure. Business units, application owners, end users, developers, and database administrators (DBAs) have yet to experience the full benefits, including increased agility, mobility, and control. These organizations must also manage a growing and fragmented database infrastructure. In addition to supporting an increased number of production databases, DBAs and development teams must be able to create and copy multiple database environments to meet business needs such as development and testing, reporting, and troubleshooting. Public cloud providers have built technology and business models to meet end-user needs for agility and control. Organizations are now under pressure to meet this challenge within the secure and compliant confines of the data center. As a result, IT departments need to deliver cost-effective alternatives to public clouds that do not compromise enterprise requirements for data protection, disaster recovery, and guaranteed service levels. Traditional on-premises infrastructure gives IT teams more control, but provisioning of database environments can take weeks. Public clouds speed up provisioning, but do not always meet business requirements for data protection, disaster recovery, and service levels. For this Oracle database-as-a-service (DBaaS) solution, Enterprise Hybrid Cloud 4.0 provides on-premises cloud services to meet these business requirements. This Oracle DBaaS solution allows customers to use Enterprise Hybrid Cloud to perform the following tasks: Day 1 Operations: Self-provision Oracle DBaaS on Enterprise Hybrid Cloud as: A single-instance Oracle Database 12c on Oracle Automatic Storage Management (ASM) An Oracle Database 12c with Oracle Real Application Clusters (RAC) and ASM This creates an Oracle 12c Container Database (CDB) with an optional Pluggable Database (PDB) in a single-tenant configuration. Day 2 Operations: Adding disks to Oracle ASM Disk Groups for both single-instance and RAC databases Adding vcpu to a virtual machine Adding memory to a virtual machine Adding or removing Oracle Enterprise Manager Monitoring 6 Enterprise Hybrid Cloud 4.0

7 Chapter 1: Executive Summary Monitoring of the complete Oracle DBaaS solution using Oracle Enterprise Manager Cloud Control 12c (OEM) and VMware vrealize Operations Manager Migrating a PDB between Oracle 12c CDBs Enterprise Hybrid Cloud Enterprise Hybrid Cloud is an enterprise-class, multitenant, multisite, scalable solution enabling IT organizations to deploy an on-premises hybrid cloud that delivers infrastructure as a service (IaaS) to their business quickly. It also provides a framework and foundation for add-on modules such as application services, database as a service (DBaaS), platform as a service (PaaS), and cloud brokering. This solution uses VMware vrealize Automation, and VMware vrealize Orchestrator. It provides configurable workflows to enable the automated deployment and management of Oracle DBaaS. Enterprise Hybrid Cloud is designed to deliver multitenancy and secure separation of resources. Cloud computing requires the ability to isolate resources and deliver secure access. Enterprise Hybrid Cloud is structured so that, if required, each tenant can be: Logically separated using vrealize Automation business groups. In this solution, the Oracle business group is assigned dedicated compute, storage, and network resources for software license compliance. Physically separated in a dedicated Workload Pod. In this solution, Oracle is restricted to dedicated VMware vsphere clusters with High Availability (vsphere HA)/Distributed Resource Scheduler (DRS). The Workload Pod can have its own servers, network, and storage resources, separate from all other tenants. These dedicated, physically separated, clustered Workload Pods are mapped to the compute resource available to the vrealize Automation business group through a VMware vcenter endpoint (either dedicated or shared). This improves service availability, and helps ensure software license compliance by restricting where the virtual machines and software are running or installed. vrealize Orchestrator integrates with vrealize Automation and enables process automation when interfacing with third-party systems. Further, vrealize Orchestrator workflows can be deployed as custom services or actions in vrealize Automation to enable complex Day 1 and Day 2 operations for Oracle DBaaS. Oracle Database Oracle Database 12c delivers industry-leading performance, scalability, security, and reliability on a choice of clustered or single servers running Microsoft Windows, Linux, or UNIX. It introduces a new architecture, Oracle Multitenant, where one or more PDBs are created inside a CDB. The multitenant architecture supports the following configurations: A single-tenant configuration, one PDB plugged into a CDB, is available for no extra cost in all editions. A multitenant option for up to 252 PDBs per CDB is an extra-cost option of Oracle 12c Enterprise Edition. Enterprise Hybrid Cloud 4.0 7

10 Chapter 2: Solution Architecture Overview This Oracle DBaaS solution provides the following application-specific functions: Automated deployment and management of Oracle Database 12c Single-instance Oracle Database with Oracle ASM Oracle Database with Oracle RAC and ASM Oracle DBaaS Day 2 operations Add new disks to Oracle ASM disk groups (single-instance and RAC) Oracle DBaaS monitoring Oracle Enterprise Manager Database Express 12c Oracle Enterprise Manager Cloud Control 12c vrealize Operations Manager PDB Migration Copy PDB users, objects and code between Oracle CDBs This Oracle DBaaS solution has been built and validated on a number of iterations and configurations of Enterprise Hybrid Cloud. The underlying physical environment is abstracted from the application layer by virtual and software-defined components. The architecture shown in Figure 1 is representative of the architecture and environments where the Oracle DBaaS solution is deployed. It shows the main components in the Automation Pod that are relevant to this solution. Figure 1. Enterprise Hybrid Cloud reference architecture with Oracle Workload Pods 10 Enterprise Hybrid Cloud 4.0

11 Chapter 2: Solution Architecture Figure 1 also shows the Oracle Workload Pod, which is a dedicated VMware ESXi cluster with vsphere HA, and with its own compute, storage, and network resources. This provides improved service availability and restricts where the virtual machines and software are running or installed, which in turn ensures software license compliance. VMware vrealize Orchestrator contains a workflow library and a workflow engine to create and run workflows that automate orchestration processes. You run workflows on the objects of different technologies that vrealize Orchestrator accesses through a series of plug-ins. vrealize Orchestrator also presents an open architecture to allow you to plug in external third-party applications to the orchestration platform. You can access vrealize Orchestrator, the vrealize Orchestrator workflows, and the objects it exposes through the vrealize Orchestrator client interface, or through Web services. This solution leverages these capabilities to provide Oracle DBaaS. Key components The following components of Enterprise Hybrid Cloud are essential in this Oracle DBaaS solution: VMware ESXi and VMware vcenter Server VMware vrealize Suite: VMware vrealize Automation VMware vrealize Operations Manager VMware vrealize Orchestrator For this solution, when used with Oracle Database 12c, these components deliver the following functionality: Provisioning of Oracle DBaaS, RAC or single-instance, using vrealize Orchestrator packages as service blueprints in the vrealize Automation portal Service maintenance/day 2 operations using vrealize Orchestrator packages as service blueprints and resource actions in the vrealize Automation portal Optional monitoring of Oracle DBaaS using OEM Cloud Control 12c Release 2, which can be integrated with VMware vrealize Operations Manager using a third-party plug-in for full stack monitoring Note: For a full overview of components, refer to Enterprise Hybrid Cloud 4:0: Foundation Infrastructure Reference Architecture Guide.

13 Chapter 3: Provisioning Oracle DBaaS Chapter 3 Provisioning Oracle DBaaS This chapter presents the following topics: Overview Preparing the Oracle DBaaS service Deploying Oracle DBaaS Enterprise Hybrid Cloud

14 Chapter 3: Provisioning Oracle DBaaS Overview Enterprise Hybrid Cloud provides a foundation for the successful and consistent deployment of Oracle DBaaS. This chapter describes the high-level process and methodology required to successfully deploy the applications by using vrealize Orchestrator with the vrealize Automation Service Catalog and the Enterprise Hybrid Cloud self-service portal. The Oracle DBaaS solution delivers a fully automated product to install and configure: Single Instance Oracle Database with Oracle ASM Oracle Database with Oracle Real Application Clusters (RAC) and Oracle ASM Preparing the Oracle DBaaS service Before provisioning a VMware virtual machine with an Oracle Database from the vrealize Automation Service Catalog, an Enterprise Hybrid Cloud administrator configures storage policies, default ASM disk sizes, and other configuration settings that are unique to each Enterprise Hybrid Cloud environment. Storage policies Storage policies provide the means for an Enterprise Hybrid Cloud administrator to classify different types of storage based on characteristics such as performance or protection. For example, a Gold storage policy might provide higher performance than a Silver storage policy. Once the storage policies are configured, the end-user can select a particular storage policy when requesting an Oracle service. ASM disk sizing Other system settings A database consists of several ASM disk groups, each with a number of disks of certain size. The solution provides configuration options to allow the Enterprise Hybrid Cloud administrator to control the number and size of these disks, based on the requested database size. The solution provides a number of other configuration options that are used to tie the solution to the current environment. Deploying Oracle DBaaS When the Enterprise Hybrid Cloud administrator has configured the Oracle DBaaS solution, it is ready for end users to deploy the Oracle Database service. Deploying an Oracle database server involves many steps. Performing these steps reliably and repeatedly is a challenge. The process is even more involved if a RAC configuration is required. This solution automates these steps so that users can easily request an Oracle database server either single-instance or RAC with just a few mouse clicks. 14 Enterprise Hybrid Cloud 4.0

15 Chapter 3: Provisioning Oracle DBaaS Figure 2 shows an Oracle DBaaS Request Form that has been requested from the service catalog. In this example, the user has requested a 200GB Oracle 12c CDB with PDB, deployed on a two-node Oracle RAC: Figure 2. Oracle DBaaS request form The automated Oracle DBaaS provisioning process includes the following steps, all driven from vrealize Orchestrator: 1. Collect request inputs The service collects inputs from the user that will drive the installation and configuration of the Oracle Database service. Oracle DBaaS deployment inputs include: System or cluster (RAC) name Requested storage space (GB) Passwords for the oracle and grid users Storage policy Number of nodes, if RAC PDB name, if a PDB is requested This user input controls the setup of the Oracle DBaaS service in the subsequent steps. 2. Provision virtual machines A virtual machine is cloned from the blueprint template by requesting the published blueprint from the vrealize Automation Service Catalog. Enterprise Hybrid Cloud

16 Chapter 3: Provisioning Oracle DBaaS If this is an Oracle RAC deployment, the required number of virtual machines is cloned based on the number of requested nodes. 3. Create database storage The chosen storage policy identifies the vcenter datastores designated to hold each ASM disk group. Using this mapping along with the requested storage size, disks are created for each ASM disk group DATA, REDO, and FRA. For a RAC deployment, an additional disk group, CRS, is created. In a RAC deployment, the disks are created on the first node of the cluster as multiwriter and are then shared with the other nodes of the cluster. All disk groups are configured to have one disk controller, except the DATA disk group, which is configured to have two controllers. The DATA disks are balanced over the two disk controllers. For each disk group, the solution calculates the required size and number of disks based on the overall database size. For the DATA disk group, the disks are balanced over the two disk controllers. 4. Install Oracle Grid software Oracle Grid software provides the platform for the single instance restart and the RAC Clustering environment, as well as for ASM. The disks created in the previous step are formatted and labeled for their respective ASM disk group. In a RAC deployment, the disks are scanned on the other nodes so that their ASM instances can see them as well. The grid software is then installed and configured, which includes running post-installation scripts as the root user. 5. Install Oracle Database software The Oracle Database software is installed next and configured to use ASM and the associated ASM disk groups. Post-installation root scripts are also run to complete the configuration. 6. Create database A CDB is created after the database software has been installed. If, in the request, the user chose to create a PDB, then it is created inside the CDB. 7. Enable local monitoring with Oracle 12c EM Express. 16 Enterprise Hybrid Cloud 4.0

17 Chapter 3: Provisioning Oracle DBaaS 8. Notify User When the service is ready for use, the user receives an with the configuration details. For example: System Information: Cluster Name: devcluster DB Size: 200 GB Nr of Nodes: 2 Storage Policy: Silver SCAN Name: devcluster-scan SCAN IP: SCAN IP: Domain Name: company.com Node 1: ora-125 Public IP: Public VIP: Private IP: Node 2: ora-124 Public IP: Public VIP: Private IP: GRID_BASE: /u01/app/grid GRID_HOME: /u01/app/12.1.0/grid ORACLE_BASE: /u01/app/oracle ORACLE_HOME: /u01/app/oracle/product/12.1.0/dbhome_1 CDB Name: devcluster PDB Name: salesdb Enterprise Hybrid Cloud

18 Chapter 4: Oracle DBaaS Day 2 Operations Chapter 4 Oracle DBaaS Day 2 Operations This chapter presents the following topics: Overview Adding disk(s) to Oracle ASM single-instance and RAC Adding/removing Oracle Enterprise Manager monitoring Adding vcpu to a virtual machine Adding memory to a virtual machine Enterprise Hybrid Cloud 4.0

19 Chapter 4: Oracle DBaaS Day 2 Operations Overview After the Oracle Database service has been provisioned, environment and service changes are sometimes required. These activities, which are known as Day 2 operations, include routine maintenance tasks and changes to the virtual infrastructure. These activities can be as simple as restarting the virtual machine, but they might also include changes that can affect the availability or cost of the service, such as adding vcpu, memory, or disks. You can run or schedule all these machine actions from the Items tab in vrealize Automation, assuming that the correct entitlements have been assigned. If an approval policy has been created against a specific action, then that change is not applied until an approver has authorized the change. Using vrealize Automation Advanced Services, you can deploy customized vrealize Orchestrator workflows as resource actions. These resource actions extend the functionality of the standard machine actions to deliver complex automated processes against the deployed virtual machine. This solution uses vrealize Orchestrator workflows, configured as resource actions, to provide the following capabilities: Adding disks to Oracle ASM single-instance and RAC Adding or removing Oracle Enterprise Manager monitoring Hot-adding vcpu to a virtual machine Hot-adding memory to a virtual machine Adding disks to Oracle ASM single-instance and RAC For this solution, the ability to create additional disks and add them to an ASM disk group is provided as a Day 2 action. New disks can be added to a disk group for single-instance databases or for RAC database deployments. Adding disks to an existing ASM disk group involves a number of steps using different tools and commands, as follows: 1. Provision new virtual disks to the virtual machine (the first node in the case of RAC). Log in to vcenter and create virtual disks on the datastore that corresponds to the disk group being modified. Create thick (eager zero) disks and, in the case of RAC, enable them as multi-writer. 2. Format and label the new disks. When the disks have been provisioned, log in to the virtual machine as root, identify the newly added disks, and format and partition them. Then label the disks properly so that they can be discovered as candidate disks by ASM. 3. Scan disks on other RAC nodes. In the case of a RAC deployment, the ASM driver on each node must scan the newly formatted and labeled disks so that they are visible to the ASM instance. 4. Add the new disks to the designated ASM disk group by running a command as the grid user. Enterprise Hybrid Cloud

20 Chapter 4: Oracle DBaaS Day 2 Operations Performing these steps manually involves running many complex commands and can be tedious and error-prone. The Oracle DBaaS Solution automates this process and provides a portal interface that lets you simply request additional storage and leaves the details to underlying workflows. When adding new disks to a disk group of an Oracle deployment, you are prompted for the following information: ASM Disk Group Name Number of additional disks to add For clarity, the entry form shows the current storage size. When you enter the number of additional disks, it shows the additional storage, as shown in Figure 3: Figure 3. Adding new disks to a disk group The new disks are the same size as the existing disks in the disk group. The workflow creates the requested disks and, in the case of a RAC deployment, makes them visible to all the nodes of the cluster. The disks are then formatted, labeled, and added to the disk group. When the disks are added to ASM, data on the disks in the disk group is automatically rebalanced across all the disks. You can use the asmcmd tool to show the composition of ASM disk groups. Figure 4 and Figure 5 show the configuration of the DATA disk group before and after new disks are added to the group. After the initial build of the Oracle server, the composition of the ASM disk groups shows that there are four disks in the DATA disk group. 20 Enterprise Hybrid Cloud 4.0

21 Chapter 4: Oracle DBaaS Day 2 Operations Figure 4. Four disks in the DATA disk group After requesting that two additional disks be added to the DATA disk group, the list of ASM disks reflects the change. Figure 5. Two disks added to the DATA disk group Adding and removing Oracle Enterprise Manager monitoring targets You can add or remove an Oracle Database server from Oracle Enterprise Manager (OEM) through a Day 2 operation, as shown in Figure 6. The solution installs or removes the Oracle Management Agent on the server and it adds or removes appropriate monitoring targets. Information about Oracle Database monitoring is described in Chapter 5. Enterprise Hybrid Cloud

22 Chapter 4: Oracle DBaaS Day 2 Operations Figure 6. Adding or removing OEM 12c Agents This process is fully automated and a password is required to complete the action. Adding vcpu to a virtual machine You can hot-add extra vcpu resources to a virtual machine without restarting the virtual machine. To hot-add vcpu to a virtual machine in vrealize Automation: 1. In the Items tab, select the machine to which you want to add new vcpu. 2. From the Actions menu, select Add vcpu. 3. From the list box, select the new total number of vcpus for the machine, as shown in Figure 7, and then click Submit. Figure 7. Adding vcpu to a machine The preceding steps reconfigure the virtual machine with the new vcpu count, as shown. 22 Enterprise Hybrid Cloud 4.0

23 Chapter 4: Oracle DBaaS Day 2 Operations The Oracle Database instance recognizes the change and reflects the new value of the initialization parameter CPU_COUNT. Adding memory to a virtual machine You can hot-add extra memory to a virtual machine without restarting the virtual machine. To hot-add memory to a virtual machine in vrealize Automation: 1. On the Items tab, select the machine to which you want to add memory. 2. From the Actions menu, select Add Memory. 3. Select the new vmemory total value, as shown in Figure 8, and click Submit. Figure 8. Adding memory to a machine The preceding steps reconfigure the virtual machine with the new memory. Enterprise Hybrid Cloud

29 Chapter 6: PDB Migration Chapter 6 PDB Migration This chapter presents the following topics: Overview PDB migration example Enterprise Hybrid Cloud

30 Chapter 6: PDB Migration Overview After a database server is created in Enterprise Hybrid Cloud, there are many ongoing maintenance tasks to perform and operational requirements to fulfill. PDB copy options and choice This chapter shows how a vrealize Orchestrator workflow can be used to migrate an Oracle 12c PDB from any source to an Oracle 12c CDB running in Enterprise Hybrid Cloud. The chapter outlines several ways to do this, including the option selected for this solution and why it was chosen. The options available to a DBA for copying a PDB are: Copy PDB over DB Link, no data (metadata only : users, schema and code) Copy PDB over DB Link, including data Use a Transportable Tablespace Clone a PDB from an RMAN CDB backup set Duplicate using RMAN on an active CDB Unplug PDB from source and plug-in PDB to destination using manifest file (XML) In deciding which method to use, there are several factors to consider, such as: Is all or part of the source database available during the process? How accessible is the data on the source (read-only or read-write) during the process? Are other tools needed (datapump, RMAN, SQL*Plus, SSH)? What is the impact on performance? What is the complexity? Do data governance, privacy, protection and ownership allow copying this data? In most business environments, different teams or projects have a copy of a data set for example for development, testing, QA, and so on. However, to comply with governance, privacy, and protection rules, this data usually needs to be restricted (subsetted) and masked. Organizations have their own tools and procedures for these tasks, which are outside the scope of this document. The database metadata does need to be copied. This can be supported by the Enterprise Hybrid Cloud environment and made available to the end user through the VRealize Automation service catalog. The option that is the most efficient, the least complex, has the least impact, and is the fastest for copying the PDB metadata only is the Copy PDB over DB Link, metadata only option. It creates a database link to the source database, and copies the PDB metadata over the link. It can be implemented in Oracle 12c, by using only SQL. 30 Enterprise Hybrid Cloud 4.0

33 Chapter 7: Conclusion Chapter 7 Conclusion This chapter presents the following topics: Summary Findings Enterprise Hybrid Cloud

34 Chapter 7: Conclusion Summary Enterprise Hybrid Cloud enables customers to build an enterprise-class, multitenant, scalable platform for complete infrastructure service lifecycle management. This solution incorporates the following concepts: Self-service and automation Multi-tenancy and secure separation Workload-optimized storage Security and compliance Monitoring and service assurance The integration of Oracle DBaaS into Enterprise Hybrid Cloud fully supports Oracle users with a self-service environment. For IT, this results in an automated, repeatable process that reduces errors and improves time-to-value. For the end-user to be able to request a multi-node clustered database on-demand, using the self-service portal is highly beneficial. It reduces significant time and effort otherwise required to deploy a cluster manually. The user simply makes the request and then receives an automated with deployment details when the request is complete. Findings This solution enables the deployment of Oracle DBaaS on Enterprise Hybrid Cloud. The key findings of this solution are as follows: The Workload Pod for Oracle DBaaS improves management of Oracle licensing compliance. Application developers and service users can self-provision Oracle DBaaS on Enterprise Hybrid Cloud as: A single-instance Oracle Database with Oracle Automatic Storage Management (ASM) An Oracle Database with Oracle Real Application Clusters (RAC) and ASM This creates an Oracle 12c Container Database (CDB) with an optional Pluggable Database (PDB) in a single-tenant configuration. The solution allows users to perform Oracle DBaaS Day 2 Operations: Add disks to Oracle ASM Disk Groups single-instance and RAC Migrate a PDB to an Oracle 12c CDB deployed on Enterprise Hybrid Cloud Add and remove Oracle DBaaS monitoring Enable monitoring of the complete Oracle DBaaS solution by using Oracle Enterprise Manager Cloud Control 12c (OEM) and VMware vrealize Operations Manager. 34 Enterprise Hybrid Cloud 4.0
