Copyright © 2009, Oracle. All rights reserved Scenario Requiring Multiple Configurations Problem: How do I configure and transition among development, QA, and production environments? Development Physical implementation QA Physical implementation Production Physical implementation - No logging - Nonparallel - Tablespace: dev_data - Table EMP Location: loc1 - No logging - Parallel - Tablespace: prod_data - Table EMP Location: loc2 Required development settings Required production settings

Copyright © 2009, Oracle. All rights reserved Loose Coupling of Metadata with Physical Implementations OWB supports one logical model and multiple physical run times: Configuration 1: Its control center points to the Development run-time location. Configuration 2: Its control center points to the QA run-time location. Configuration 3: Its control center points to the Production run-time location. Development Physical implementation QA Physical implementation Production Physical implementation

Copyright © 2009, Oracle. All rights reserved Each Configuration Records the Physical Settings of Its Target Environment Named configurations for multiple deployments No need to write scripts to change logging, tablespace names, and so on Physical configuration: Development - No logging - Nonparallel - Tablespace: dev_data - Table EMP Location: loc1 - No logging - Parallel - Tablespace: prod_data - Table EMP Location: loc2 Physical configuration: Production Single logical design

Copyright © 2009, Oracle. All rights reserved Multiple Named Configurations: Why and How Why should I use multiple named configurations? –To maintain a single design for objects –To change the generated code per target database –To deploy, without hard-coding and writing scripts, to different repositories in a controlled way How do I use multiple named configurations? –Separate logical from physical with a loose coupling of logical design and physical implementation. — Define named configurations (holding physical information for objects) for each of your run times. — Active configuration substitutes physical properties into generated code. –Deploy code into its targeted database.

Copyright © 2009, Oracle. All rights reserved Deploying a Selected Configuration A single logical design can be deployed to different repositories by applying different configurations.

Copyright © 2009, Oracle. All rights reserved Setting the Active Configuration Only one configuration can be active at a time. There are two ways to set the active configuration. To quickly check which configuration is active, examine the Design Center status bar. 1 2

Copyright © 2009, Oracle. All rights reserved Cloning a Database to Create Identical Dev-QA-Prod Systems In contrast to deploying different versions, if you want to rapidly roll out a set of identical systems, you should consider cloning the database. The process of cloning typically changes host names and service names. The host names and service names are stored in the control center repository in each target repository schema. You need to change their persisted values after cloning. Clone and then change host and service names. Design repository Host name: A svce. Name: A schema: A Development Host name: X svce. Name: X schema: A Production Host name: Z svce. Name: Z schema: A QA Host name: Y svce. Name: Y schema: A

Copyright © 2009, Oracle. All rights reserved Creating a New Configuration Template Configuration template has a column called “Seeded Default” that contains the default repository values. The column to the right of the defaults contains the property values for a different configuration template.

Copyright © 2009, Oracle. All rights reserved Associating a Configuration Template with a Configuration Create Configuration Wizard lets you select a different configuration template if you want to override the system’s default configuration values. The Configurations drop-down list is now on the toolbar, and is therefore easily visible and accessible. Select Create New Configuration to create a new configuration.

Copyright © 2009, Oracle. All rights reserved Overriding Default Configuration Settings If DEFAULT_CONFIGURATION is active, note that the CHANNELS table configuration shows default settings. When PRD_CONFIG is active, the settings you applied for the PARALLEL property of the Tables object type is effective. So the CHANNELS table uses the new configuration settings.

Copyright © 2009, Oracle. All rights reserved Practice 1-2 Overview: Using Configuration Templates In the hands-on practice, you will perform the following: Create a new configuration template Associate the new template with a new configuration

Copyright © 2009, Oracle. All rights reserved Steps for Setting Up OWB in a RAC Environment Install OWB. Configure database and OWB. Monitor nodes. Troubleshoot. 1. Decide whether to use OWB with shared storage or with nonshared local disks on each RAC node. Same path for each OWB install. 2. Choose Cluster or Local Installation; run root.sh on each node. 4. Use Runtime Assistant on other nodes to register the repository. 3. Install OWB repository only once, to one node. If using a shared disk, install repository there. 6. Replicate RTREPOS.PROPERTIES and TNSNAMES.ORA on each node. 7. Define OWB locations with TNS names, not host:port:service. 8. Use OWB Browser to monitor, enable, or disable Control Center Service on a node. 9. Search logs on nodes, run helpful utilities, avoid common mistakes. 5. On the database, set MAX_COMMIT_PROPAGATION_DELAY to 0.
