15 1 Using This Tutorial This chapter provides information that you need to know before using this tutorial. Intended Uses This tutorial is designed to be used in one of two ways: As a quick overview of the steps needed to configure resources (such as single-instance databases, Oracle Forms Servers, Oracle Reports Servers, and Oracle HTTP Servers) to be highly available using Oracle Fail Safe As a step-by-step introduction to using Oracle Fail Safe Manager If you intend to use the tutorial this way, first ask your cluster administrator for at least five IP addresses that you can use on the cluster for virtual addresses. In addition, it is best to follow the lessons in order. This tutorial provides the basic steps for configuring resources to make them highly available; it does not provide detailed information on the concepts behind high availability. You may find it helpful to refer to the Oracle Fail Safe Concepts and Administration Guide while using this tutorial. Cluster Setup This tutorial is intended to be run on a two-node cluster. Terminology The following terminology is frequently used in this tutorial: Cluster: A group of independent computing systems that operates as a single virtual system. Using This Tutorial 1-1

16 Failover: The process of taking cluster resources offline on one node and bringing them back online on another node. This process can either be planned (upgrades or maintenance) or unplanned (system failure). Group: A logical collection of cluster resources that forms a minimal unit of failover. In a failover situation, the group is moved to a failover node. A group resides on only one cluster node at a time. Resource: A physical or logical component that is available to a computing system. For example, disks, the network IP address, Forms Servers, Reports Servers, and Web servers are resources. Virtual address: A network address at which the resources of a group can be accessed, regardless of the hardware server hosting those resources. Virtual server: A group with one or more virtual addresses. Requirements The following lists specify the requirements for the lessons of the tutorial. See the Oracle Fail Safe Release Notes for a list of supported software releases. Creating a Sample Single-Instance Database A supported release of the Oracle database software is installed. Creating and Adding a Forms Server and an Oracle HTTP Server to a Group Oracle9i Application Server is installed on both cluster nodes.

19 2 Invoking Oracle Fail Safe Manager and Verifying the Cluster This chapter describes the steps necessary to invoke Oracle Fail Safe Manager and to verify the cluster. Invoking Oracle Fail Safe Manager and Verifying the Cluster 2-1

20 Invoking Oracle Fail Safe Manager 2.1 Invoking Oracle Fail Safe Manager To invoke Oracle Fail Safe Manager from the taskbar, click the Start button, select Programs, then the Oracle home into which you installed Oracle Fail Safe Manager, then select Oracle Fail Safe Manager. In this example, the Oracle home is Ofs. 2-2 Oracle Fail Safe Tutorial

21 Populating the Tree View 2.2 Populating the Tree View When you invoke Oracle Fail Safe Manager, the Manager opens and if no clusters have been added to the tree view previously, the Add Cluster to Tree dialog box opens. If this dialog box opens, enter the cluster alias of the cluster you want to manage. If the tree view is already populated, but the cluster you want to manage is not in the tree view, see Section 2.3. Invoking Oracle Fail Safe Manager and Verifying the Cluster 2-3

22 Adding a Cluster to a Populated Tree View 2.3 Adding a Cluster to a Populated Tree View If the tree view already contains a list of clusters, but not the one you want to manage, you can add a cluster to the populated tree view. On the File menu, select Add Cluster to Tree. 2-4 Oracle Fail Safe Tutorial

23 Using the Add Cluster to Tree Dialog Box 2.4 Using the Add Cluster to Tree Dialog Box Enter the alias for the cluster that you want to manage in the Cluster Alias field, then click OK. Invoking Oracle Fail Safe Manager and Verifying the Cluster 2-5

24 Connecting to the Cluster 2.5 Connecting to the Cluster After the tree view is populated with one or more cluster aliases, you must connect to the cluster or clusters before you can manage them with Oracle Fail Safe Manager. In the tree view, select the cluster to which you want Oracle Fail Safe Manager to connect. Then, on the File menu, select Connect to Cluster. Oracle Fail Safe opens the Connect to Cluster dialog box. 2-6 Oracle Fail Safe Tutorial

25 Using the Connect to Cluster Dialog Box 2.6 Using the Connect to Cluster Dialog Box Enter a user name and password for a domain account that has Administrator privileges on all nodes of the cluster to which you want to connect. Next, enter the account domain name. Select Save As Local Preferred Credentials if you want Oracle Fail Safe Manager to save the connection information in a file on the local system (the password will be encrypted). If you save local preferred credentials, the next time you open Oracle Fail Safe Manager, you can automatically connect to the cluster by expanding the tree view for that cluster. Invoking Oracle Fail Safe Manager and Verifying the Cluster 2-7

26 Verifying the Cluster 2.7 Verifying the Cluster Before beginning work with Oracle Fail Safe Manager, verify that the cluster hardware and software are correctly configured by using the Verify Cluster command. If this is your first time using Oracle Fail Safe with this cluster, a window asking you to verify the cluster opens immediately after you connect to the cluster. To verify the cluster, click the Verify Cluster button. If this is not your first time using Oracle Fail Safe with this cluster, on the Troubleshooting menu, select Verify Cluster. 2-8 Oracle Fail Safe Tutorial

27 Viewing the Results of the Verify Cluster Operation 2.8 Viewing the Results of the Verify Cluster Operation Oracle Fail Safe displays the progress of the Verify Cluster operation. Invoking Oracle Fail Safe Manager and Verifying the Cluster 2-9

28 Viewing the Results of the Verify Cluster Operation 2-10 Oracle Fail Safe Tutorial

29 3 Creating a Group This chapter describes the steps necessary to create a group with Oracle Fail Safe Manager. Creating a group is the first step in making most resources (such as single-instance databases, Forms Servers, Reports Servers, and Oracle HTTP servers) highly available. Creating a Group 3-1

30 Invoking the Create Group Wizard 3.1 Invoking the Create Group Wizard In the tree view, select the cluster on which you want to create a group. Then, on the Groups menu, select Create to open the Create Group Wizard. 3-2 Oracle Fail Safe Tutorial

31 Naming and Describing the Group 3.2 Naming and Describing the Group The Create Group Wizard steps you through the process of creating a group. Enter FSTutorial as the name of the group, and if you want, enter a description of the group. Creating a Group 3-3

32 Specifying the Failback Policy 3.3 Specifying the Failback Policy The Failback policy determines whether a group that has previously failed over is returned to the node on which you prefer it to run when that node comes back online. Select "Allow failback." Then select "Fail back between" and enter 2 and then 3. This specifies that if a previously unavailable node comes back online, failback will be scheduled to occur between the hours of 2 a.m. and 3 a.m. See the Oracle Fail Safe Concepts and Administration Guide for more information on the various failback policy options. 3-4 Oracle Fail Safe Tutorial

33 Specifying the Preferred Nodes 3.4 Specifying the Preferred Nodes A preferred node is the node on which you want the group to run when all cluster nodes are running. When a previously unavailable node comes back online, the cluster software reads the preferred nodes list to determine if the group should be failed back to a preferred node. The first running node in the preferred nodes list is the one to which the group will fail back. If you do not specify a preferred nodes list, failback is disabled and the group will never fail back. Move one of the nodes in the Available Nodes list to the Preferred Nodes list. Creating a Group 3-5

34 Finishing Creating a Group 3.5 Finishing Creating a Group Before the group is created, you have an opportunity to review the properties you have selected. If the properties are incorrect, click Cancel and then Back to make corrections. If the properties are correct, click OK, and Oracle Fail Safe will create the group. 3-6 Oracle Fail Safe Tutorial

35 Responding to the Virtual Address Question 3.6 Responding to the Virtual Address Question After creating the group, Oracle Fail Safe asks if you want to add a virtual address to the group. When a group contains a virtual address, the group is accessible by clients at the same network address, regardless of which cluster node is hosting the group. If you click Yes, Oracle Fail Safe opens the Add Virtual Address Wizard immediately. Typically, you would click Yes. However, for the purposes of this tutorial, click No. In Chapter 4, the tutorial will show you how to create a virtual address as a separate step. Creating a Group 3-7

36 Responding to the Virtual Address Question 3-8 Oracle Fail Safe Tutorial

37 4 Adding a Virtual Address to a Group This chapter describes the steps necessary to add a virtual address to a group with Oracle Fail Safe Manager. Oracle Fail Safe Manager does not allow you to add any other resources (other than a generic service) to a group until at least one virtual address has been added to the group. Without a virtual address, clients cannot connect to resources that have been added to a group. Adding a Virtual Address to a Group 4-1

38 Opening the Add Resource to Group Wizard 4.1 Opening the Add Resource to Group Wizard In the tree view, select the group to which you want to add a virtual address. Next, on the Resources menu, select Add to Group to open the Add Resource to Group Wizard. 4-2 Oracle Fail Safe Tutorial

39 Specifying the Resource Type and Group 4.2 Specifying the Resource Type and Group On the first page of the wizard, select the Virtual Address resource type, the FSTutorial group, and then click Next. Adding a Virtual Address to a Group 4-3

40 Describing the Network 4.3 Describing the Network When you add a virtual address to a group, you need to define the network on which the virtual address runs. If you do not know which addresses are available as virtual addresses on your cluster, ask your cluster administrator. Enter the data on the wizard page as follows: 1. In the Network section of the page, select "Show networks accessible by clients," and in the Network box, select Public. 2. In the Virtual Address section of the page, enter the host name for the virtual address that you want to create in the Host Name box (your value will be different than the one shown in the image), and then press the Tab key. When you press the Tab key, Oracle Fail Safe resolves the host name to an IP address. Your values for the virtual address will be different from the ones shown in the image. Also, do not use the cluster alias; in this example, the cluster alias is ntclu Click Finish. 4-4 Oracle Fail Safe Tutorial

41 Finishing Adding the Virtual Address 4.4 Finishing Adding the Virtual Address Oracle Fail Safe asks you to check the properties you have selected for the virtual address. If they are correct, click OK. Otherwise, click Cancel and then Back to change the properties. After you add at least one virtual address to the group, you are ready to add a resource to the group (such as an Oracle single-instance database, Oracle Forms Server, Oracle Reports Server, Web server, or other resource). Adding a Virtual Address to a Group 4-5

42 Viewing the Group Properties 4.5 Viewing the Group Properties Frequently, you will need the virtual address or addresses of a group when you are adding resources to the group. These addresses are displayed in the wizard you use to add a resource to a group. You can also see a list of these addresses in the Virtual Addresses property page. This property page shows the virtual address that you just added to the group. 4-6 Oracle Fail Safe Tutorial

43 5 Creating a Sample Single-Instance Database This lesson shows you how to create a sample single-instance database called SAMPLEDB. The rest of this tutorial assumes you have created this database. Creating a Sample Single-Instance Database 5-1

44 Opening the Create Sample Database Dialog Box 5.1 Opening the Create Sample Database Dialog Box In the tree view, select the cluster (or an object on the cluster) on which you want to create the sample database. Then, on the Resources menu, select Create Sample Database to open the Create Sample Database dialog box. 5-2 Oracle Fail Safe Tutorial

45 Using the Create Sample Database Dialog Box 5.2 Using the Create Sample Database Dialog Box Enter a service name of SAMPLEDB, select a disk and node combination on which to build the sample database, and then select the version of the Oracle database that you want to create and the Oracle home in which to create it. For the disk resource, Oracle Corporation recommends you select a disk other than that which is used for the quorum resource. (To view the disk used for the quorum resource, select the cluster alias in the tree view, then click the Quorum tab.) Click OK. The sample database always uses the SYS account with a password of change_on_ install. Do not use the sample database as a production database. Creating a Sample Single-Instance Database 5-3

46 Starting the Default Oracle Intelligent Agent 5.3 Starting the Default Oracle Intelligent Agent Oracle Fail Safe opens a Creating Sample Database window to display the progress of the operation. This may take a few minutes. During the operation, Oracle Fail Safe opens a Clusterwide Operation Query window to ask if you want to restart the default Oracle Intelligent Agent. Click Yes. 5-4 Oracle Fail Safe Tutorial

47 Viewing the Progress of the Clusterwide Operation 5.4 Viewing the Progress of the Clusterwide Operation When the operation completes, Oracle Fail Safe opens a Clusterwide Operation Status window to let you know whether the operation has completed successfully. Click OK. Creating a Sample Single-Instance Database 5-5

48 Viewing the Progress of the Clusterwide Operation 5-6 Oracle Fail Safe Tutorial

49 6 Verifying a Standalone Single-Instance Database If you add a standalone database (that you did not create using Create Sample Database) to a group, you should verify the database before adding it to a group. When you verify a standalone database, Oracle Fail Safe uses data that you supply to attempt to fix any problems it finds clusterwide. Because Oracle Fail Safe created it, you do not need to verify the database that you created in Chapter 5. However, for the purpose of demonstration, you will do so in this lesson. Verifying a Standalone Single-Instance Database 6-1

50 Using the Verify Standalone Database Command 6.1 Using the Verify Standalone Database Command In the tree view, select the SAMPLEDB.us.oracle.com database. Then, in the Troubleshooting menu, select Verify Standalone Database. 6-2 Oracle Fail Safe Tutorial

51 Using the Verify Standalone Database Dialog Box 6.2 Using the Verify Standalone Database Dialog Box The contents of the database information fields are retrieved automatically. If a value is too long for a field, you may not see the entire value. In the Account box, select the "Use operating system authentication" option. (If a window opens with a question similar to the following, click Yes: "To use operating system authentication, the user, domain\administrator must be added to the dba group ORA_OFS1_DBA. Should Oracle Fail Safe add this user for you?") Verifying a Standalone Single-Instance Database 6-3

52 Viewing the Progress of the Clusterwide Operation 6.3 Viewing the Progress of the Clusterwide Operation Oracle Fail Safe displays the results of the Verify Standalone Database operation. (During the operation, a message window may ask if you want to start the SAMPLEDB instance. If this message is displayed, click Yes.) 6-4 Oracle Fail Safe Tutorial

53 7 Adding a Single-Instance Database to a Group This lesson shows how to add a single-instance database to a group. When you add a single-instance database to a group, you make that database highly available. If the node on which the database is currently running is taken offline or fails, the database is restarted on a surviving cluster node. In this lesson, you will add the sample database that you created in Chapter 5 to the FSTutorial group that you created in Chapter 3. Adding a Single-Instance Database to a Group 7-1

54 Invoking the Add Resource to Group Wizard 7.1 Invoking the Add Resource to Group Wizard In the tree view, select the SAMPLEDB.us.oracle.com database, then on the Resources menu, select Add to Group. 7-2 Oracle Fail Safe Tutorial

55 Using the Add Resource to Group Wizard 7.2 Using the Add Resource to Group Wizard The Add Resource to Group Wizard steps you through the process of adding the database to the group. On this page, select Oracle Database (if it is not already selected) and then select the FSTutorial group from the Group Name pull-down menu. Click Next. Adding a Single-Instance Database to a Group 7-3

56 Specifying the Database Identity 7.3 Specifying the Database Identity Typically, the Service Name, Instance Name, Database Name, and Parameter File fields are retrieved automatically. However, if the parameter file disk is not on the same node as the database instance, then the database name will not be prefilled. If this is the case, enter the database name in the Database Name field. Click Next. 7-4 Oracle Fail Safe Tutorial

57 Selecting a Database Authentication Method 7.4 Selecting a Database Authentication Method Oracle Services for MSCS must have access to the database. Oracle Services for MSCS accesses the database from two accounts, the account running the Oracle Services for MSCS service and the account running the Cluster Server service. The account running the Oracle Services for MSCS service accesses the database during configuration and verification operations; the account running the Cluster Server service accesses the database when monitoring database status and when placing the database online or taking it offline. You can choose for the services to access the database using the account or accounts under which they are running (which is called operating system authentication) or to access the database using the SYS account. Note: This page will not be presented if the account (or accounts) under which the services are running is already a member of either the ORA_DBA or ORA_<SID>_DBA Windows operating system group. Select the "Use operating system authentication" option. Adding a Single-Instance Database to a Group 7-5

58 Adding the Account to the Windows ORA_<SID>_DBA Group 7.5 Adding the Account to the Windows ORA_<SID>_DBA Group When you select the "Use operating system authentication" option, Oracle Fail Safe opens a window to confirm that you want to add the account or accounts under which the Oracle Server for MSCS and Cluster Server services are running to the ORA_<SID>_DBA group. Click Yes. Then click Next in the Database Authentication Wizard page. In this example, Oracle Services for MSCS and MSCS are both running under the nedcdomain\cluadmin account and OFS1 is the SID of the SAMPLEDB database. If they were running under different accounts, both would be added to the ORA_ OFS1_DBA group. (The values presented to you when you follow this tutorial may be different.) 7-6 Oracle Fail Safe Tutorial

59 Specifying a Password File 7.6 Specifying a Password File On this page, you can choose whether or not Oracle Services for MSCS will create a password file for the database on each cluster node. If you choose not to have Oracle Services for MSCS create a password file on each cluster node, then database administrators who want to access the database must be members of the ORA_DBA or ORA_<SID>_DBA Windows operating system group and will only be able to perform database administration tasks from the node on which the database resides; applications such as Recovery Manager will not be able to access the database from a noncluster node. This lesson specifies that Oracle Services for MSCS will create a password file. Select the "Yes, create the password file" option, and enter and confirm the password for the SYS account. The default password for the SYS account is change_on_install. Adding a Single-Instance Database to a Group 7-7

60 Finishing Adding the Database 7.7 Finishing Adding the Database Oracle Fail Safe asks you to check the properties you have selected for the database. If they are correct, click OK. Otherwise, click Cancel and then click Back to change the properties. 7-8 Oracle Fail Safe Tutorial

61 Shutting Down the Database 7.8 Shutting Down the Database If the database is running, Oracle Fail Safe displays a window to warn you that it must shut down the database. Click Yes to shut down the database and continue the process. Adding a Single-Instance Database to a Group 7-9

62 Viewing the Progress of the Clusterwide Operation 7.9 Viewing the Progress of the Clusterwide Operation Oracle Fail Safe displays the progress of the Add Database to Group operation Oracle Fail Safe Tutorial

63 8 Verifying a Group A group verification checks that the selected group is configured correctly. Over time, as your system becomes more complex and hardware and software configurations change, you may find that resource dependencies have changed. The Verify Group command makes it easy to restore the configuration to working order. When you use a Verify Group command, Oracle Fail Safe attempts to correct any configuration problems it finds. It is not necessary to verify a group immediately after you create it, but it is done in this lesson to demonstrate the operation. Verifying a Group 8-1

64 Using the Verify Group Command 8.1 Using the Verify Group Command In the tree view, right-click the FsTutorial group name, then select Verify Group. 8-2 Oracle Fail Safe Tutorial

65 Viewing Progress 8.2 Viewing Progress Because the Verify group operation is applied clusterwide and involves numerous steps, it can take a few minutes to complete. Oracle Fail Safe Manager displays the progress of the operation to you. When the operation is complete, click OK in the Cluster Operation Status window and Close in the Verifying Group FsTutorial window. Verifying a Group 8-3

66 Viewing Progress 8-4 Oracle Fail Safe Tutorial

67 9 Balancing the Workload Oracle Fail Safe Manager makes it easy to balance the workload across the nodes in the cluster using a process called planned failover. You can use planned failover to adjust the initial setup of the cluster, or to adjust the setup if the cluster environment changes. Balancing the Workload 9-1

68 Initial Set Up for Performing a Planned Failover 9.1 Initial Set Up for Performing a Planned Failover Create three groups: Sales, Marketing, and Customers. Create Sales and Marketing on one node (NTCLU-151 is used in this example); create Customers on the other node (NTCLU-152 is used in this example). Enable failback for each group, and set the current node of each group at the top of the Preferred Owner Nodes list. See Chapter 3 for instructions on creating a group. For the purposes of this example, you do not need to add virtual addresses to the new groups. The following figure shows the initial configuration of the cluster: Suppose that you have recently added more CPUs to NTCLU-152. Node NTCLU-152 can better handle the load of the Sales and Marketing groups, and NTCLU-151 would now be a better place for the Customers group. You can move the groups to the new, more capable system with minimal interruption in service to your users. 9-2 Oracle Fail Safe Tutorial

69 Moving the Sales Group 9.2 Moving the Sales Group Because NTCLU-152 is the more robust system, the first step is to move Sales and Marketing groups to NTCLU-152. To move the Sales group from NTCLU-151 to NTCLU-152, right-click on the Sales group and select Move to a Different Node. (Your node names will be different.) Balancing the Workload 9-3
