4 Upgrading Scaled-Out Systems
This chapter contains the procedure to upgrade a multi-node, scaled-out deployment to the latest release of Oracle Analytics Server.
- About the Multi-Node Upgrade Process
- About the SSL Enabled and Scaled-Out System Upgrade Process
Review the flowchart and roadmap for an overview to upgrade from a multi-node, SSL enabled and scaled-out 12.2.1.4.0 Oracle Business Intelligence or a previous Oracle Analytics Server release deployment. - Checking the Status of the Servers in the Oracle Analytics Server Instance
The following servers must be in the running state on both the nodes: Servers hosting Oracle Analytics Server instance (bi_server), OBIPS, OBIJH, OBICCS, OBICH, and OBIS. - Installing the Product Distributions on Node1 and Node2
Before beginning your upgrade, download Oracle Fusion Middleware Infrastructure 12.2.1.4.0 andOracle Analytics Server distributions on the target system and install them on both the nodes using Oracle Universal Installer. - Running a Pre-Upgrade Readiness Check
To identify potential issues with the upgrade, Oracle recommends that you run a readiness check before you start the upgrade process. Be aware that the readiness check may not be able to discover all potential issues with your upgrade. An upgrade may still fail, even if the readiness check reports success. - Stopping Servers and Processes
Stop the Oracle Analytics server instance and the system components on Node1. - Upgrading Product Schemas
After stopping servers and processes, use the Upgrade Assistant to upgrade supported product schemas to the current release of Oracle Fusion Middleware. - Backing Up the mapViewerConfig.xml File
The mapViewerConfig.xml file is overwritten by the reconfiguration templates when you run the Reconfiguration Wizard. Therefore, you must back up the mapViewerConfig.xml file before reconfiguring your existing domain. - About Reconfiguring the Domain
Run the Reconfiguration Wizard to reconfigure your domain component configurations to Oracle Analytics Server. - Restoring the mapViewerConfig.xml File
ThemapViewerConfig.xmlfile is overwritten when you run the Reconfiguration Wizard on your domain. You can confirm that themapViewerConfig.xmlfile is overwritten by checking its file size. You must restore the original file that you backed up before upgrading your domain with the Upgrade Assistant. - Upgrading Domain Component Configurations
Use the Upgrade Assistant to upgrade the domain component configurations inside the domain to match the updated domain configuration. - Verifying the Domain-Specific-Component Configurations Upgrade
To verify that the domain-specific-component configurations upgrade was successful, sign in to the Administration console and the Oracle Enterprise Manager Fusion Middleware Control and verify that the version numbers for each component is the latest. - Packing the Upgraded Domain on Node1
After upgrading the existing domain to Oracle Analytics Server, pack the upgraded domain on Node1. - Unpacking the Upgraded Domain on Node2
You must unpack the domain that you packed on Node1 to Node2, which is the remote node. - Synchronizing Connection Details to the Mid-Tier Database
Synchronizing connection details to the mid-tier database ensures that the Oracle Analytics Server components can access the mid-tier database when connection details, including credentials, are changed. - Starting the Node Manager on Node2
After you have upgraded the Oracle BI domain on Node1, start the Node Manager on Node2. - Starting Servers and Processes
Start the Oracle Analytics Server instance and the system components on Node1. - Checking the Status of the Servers in the Oracle Analytics Server Instance
The following servers must be in the running state on both the nodes: Servers hosting Oracle Analytics Server instance (bi_server), OBIPS, OBIJH, OBICCS, OBICH, and OBIS.
