For this release, this section includes the following topics:
Deploying Oracle Data Integrator
Review information in this section, which describes considerations for configuring Oracle Data Integrator repository connections to Oracle Real Application Clusters:
Oracle RAC Retry Connectivity for Source and Target Connections
When you configure Oracle Data Integrator (ODI) Oracle Real Application Clusters (RAC) connections, Oracle RAC retry is supported for the ODI master or ODI work repository.
ODI uses transactional connections to source and target connections while running ODI scenarios. For these source and target connections, ODI doesn't support RAC retry connectivity. You can't migrate these transactions to another node in Oracle RAC.
Configuring ODI Repository Connections to Oracle RAC
When you create an ODI repository using Repository Creation Utility (RCU), you specify the work repository connection JDBC URL. RCU stores the URL in the master repository contents. If a work repository JDBC URL is a single node URL, Oracle recommends that you modify the URL to include the Oracle Real Application Clusters (Oracle RAC) failover address.
If Oracle RAC is not configured with Single Client Access Name (SCAN), you can provide details of the Oracle RAC instances. In the work repository JDBC URL field, enter the Oracle RAC connectivity address in the format host:port. See the following example.
If Oracle RAC is configured with SCAN, provide Oracle RAC instance details with the SCAN address.
The following example shows the JDBC URL format to connect to an Oracle RAC with two hosts when it doesn't use SCAN:
jdbc:oracle:thin:(DESCRIPTION =(LOAD_BALANCE=ON) (ADDRESS =(PROTOCOL =tcp) (HOST =host1)(PORT =port1)) (ADDRESS =(PROTOCOL =tcp)(HOST =host2) (PORT =port2)) (CONNECT_DATA =(SERVER=dedicated) (SERVICE_NAME=service_name)))

About Oracle Data Integrator Scheduler Node Failure
If a WebLogic Server failover occurs, the other WebLogic Server instance becomes the scheduler. A Coherence cache handles the scheduler lifecycle. Locking guarantees the scheduler uniqueness, and event notification provides scheduler migration.
When an agent restarts and computes its schedule, it takes into account schedules in progress, which automatically continue their execution cycle beyond the server startup time. New sessions trigger as if the scheduler never stopped. Stale sessions move to an error state and remain in that state when they restart.
In an Oracle Data Integrator Agent cluster, if the Agent node that is the scheduler node fails, another node in the cluster takes over as the scheduler node. The new scheduler node reinitializes and runs all schedules from that point forward.
If a scheduled scenario with a repeatable execution cycle is running when the node crashes, the scenario doesn't continue its iterations on the new scheduler node from the point at which the scheduler node failed. For example, if a scheduled scenario is configured to repeat the execution 10 times after an interval of two minutes and the scheduler node fails during the third execution, the new scheduler node doesn't continue running the scenario for the next eight executions.
Deploying Oracle Application Development Framework
Review this section for special considerations to deploy Oracle Application Development Framework (ADF).

Oracle JRF Asynchronous Web Services (Pinned Service Behavior)
When you use Oracle JRF Asynchronous Web Services, the asynchronous web service is pinned to a service and doesn't fail over. When you use a reliability protocol such as WS-RM, the higher-level protocol reconnects to a new server after a failure.
For more on Oracle JRF Asynchronous Web Services, see Oracle JRF and ADF TemplatesOracle JRF Template in Domain Template Reference.
Keep the following in mind as you deploy Oracle Business Intelligence (BI).
About BI Session Failover
If a BI Managed Server and/or host crashes, a user may need to log in again. This depends on which application they are using at the time of the crash and whether or not SSO is in use.
About BI Essbase
Essbase doesn't support a high availability configuration. If a server fails, there is no loss of state; you can recover from a failure by redploying Essbase Cube.
About BI Studio
Studio doesn't support a high availability configuration. Oracle recommends performing xml import/export on a regular basis. This is the best practice for Studio recovery from a catalog failure.
About Specifying Ports for Multiple Node Managers
If you have more than one node manager per machine, verify that you specify your ports.
See About Node Manager Configuration in a Typical Enterprise Deployment in Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Business Intelligence.
About RAC Database Post Installation Configuration
Oracle BI requires additional configuration steps for whole server migration after installation.
See Using Whole Server Migration and Service Migration in an Enterprise Deployment in Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Business Intelligence for these steps.
About Scaling Out BI Publisher
Completing BI scale out requires tasks in addition to typical scale out steps.
Oracle BI requires additional steps after you follow scale out steps in Scaling Out a Topology (Machine Scale Out). Oracle BI requires you to change
setDomainEnv.sh to the updated singleton-data-directory setting (SDD).
To complete Oracle BI scale out:
- Move the SDD from local to shared storage so that all hosts can access it using the same path. For example, move it to:
- Open DOMAIN_HOME/config/fmwconfig/bienv/core/bi-environment.xml (element bi:singleton-data-directory).
- Change the
xdo.server.config.dirpath to refer to the new SDD path you just created.
- Restart the server.
Keep the following in mind as you deploy Forms.
Reports has the certain considerations you need to know about for a high availability set up.
About Scaling Up in Reports
If you scale up Reports components, Oracle recommends that you bring down all nodes and then restart them when configuration is complete.
See Starting and Stopping Oracle Reports Server in Oracle Fusion Middleware Publishing Reports to the Web with Oracle Reports Services.
About Reports Multicast Communication
Reports cluster members or individual clients use multicast to discover other nodes. There is no workaround to using multicast.
About Reports Shared-File Based Cache
Reports has shared file based cache as a singleton. If the cache fails, high availability also fails.
There is no workaround. If shared-file based cache fails, you must restart Reports servers.
About Reports Database Service Failure
Reports components can tolerate database failure. Reports retries the database connection three times. After the database is up, you must run Reports again.
Deploying Oracle Business Process Management
Keep the following in mind when you deploy Oracle Business Process Management in a high availability environment.
