This chapter describes some of the configuration tasks you must perform before using products like interMedia, Net8, Oracle Enterprise Manager, and Oracle options.Where appropriate, the chapter provides references to other guides for those configuration tasks.
The chapter focuses on the post-installation configuration of a variety of Oracle products.
What Products Must You Configure?
Note: The directory path examples in this chapter follow Optimal Flexible Architecture (OFA) guidelines (for example, ORACLE_BASE\ORACLE_HOME\RDBMS\ADMIN). If you specified non-OFA compliant directories during installation, your directory paths will differ. See "OFA and Multiple Oracle Home Configurations" for more information. |
The configuration tasks that you must perform are determined by the products that you install and the network configuration files that you use.
Some products (such as Oracle Enterprise Manager) must always be manually configured. The configuration requirements for other products (such as Oracle options) are determined by how you install the product and the network configuration files that you use.
Review the following table and the sections/documents referenced to identify the configuration that you must perform after product installation and before using them.
Product | Configuration automatic? | See the following for Instructions... |

Oracle enables file management in a variety of media, from text, to audio, to video. Files in each medium are managed through a specific "option" such as Oracle interMedia. This section describes interMedia configuration and describes each medium management component.
interMedia Audio manages audio data in multiple file formats in an Oracle database.
Types of audio data supported include conversations, songs, and other sounds in popular audio file formats. This makes it possible to integrate audio data with other application-specific object-relational data.
interMedia Video manages video data in multiple video file formats. This makes it possible to integrate video data with other application-specific object-relational data.
interMedia Image provides image storage, retrieval, and format conversion capabilities through an object data type (ODT). It also supports image storage, using Binary Large Objects (BLOBs) and references to image data residing in external files (BFILEs).
The Image component of interMedia also comes with a sample demonstration that shows how an image is extracted from an Oracle database.
interMedia Locator enables Oracle8i to support online internet-based geocoding facilities for locator applications and proximity queries.
Review the following table to determine how to configure interMedia Audio, Video, Image, and Locator.

By installing interMedia Text with an Oracle database server, client tools such as SQL*Plus, Oracle Forms, and Pro*C/C++ are able to retrieve and manipulate text in an Oracle database.
Oracle interMedia Text manages textual data in concert with traditional data types in an Oracle database. When text is inserted, updated, or deleted, interMedia Text automatically manages the change.
If you... | Then... |
---|---|
Installed Oracle interMedia Text from the Oracle8i Enterprise Edition CD-ROM and you do not have a previous release of interMedia Text installed (formerly called ConText) |
See description below this table. |
Migrated your database, you may need to configure Net8 for external procedures. Otherwise Oracle interMedia Text may not work. In any case other than migration, Net8 should be configured correctly by default to work with Oracle interMedia Text. |
See the guides Oracle8i interMedia Text Migration and Oracle8i interMedia Text Reference. |
If you are indexing formatted documents such as Microsoft Word... |
You must set your environment to use the INSO filter before you can index your documentation set. For more information on setting up your environment for INSO filtering, see Appendix-C of the Oracle8i interMedia Text Reference. |
If one of the following is true, the Oracle database is already configured for use with Oracle interMedia Text:
- Install Oracle8i Enterprise Edition with the Custom installation type.
- In the Available Product Components dialog box, select Oracle Server.
- When prompted to run Oracle Database Configuration Assistant, click Yes.
- Select the Typical database creation type.
- Select "Copy existing database files from the CD".
Additional Information: See Chapter 7, "Starter and Custom Databases" for more information about creating a starter database.
If none of these are true, you must configure the Oracle database for use with Oracle interMedia Text by doing one of the following:
You can use Oracle Database Configuration Assistant to configure an Oracle database for use with Oracle interMedia Text either at the time you create the database or later.
To configure... | Do this... |
---|---|
At the time you create the database |
Select interMedia Text in the Database Cartridges and Options page. |
At a later time |
Manually configuring an Oracle database for use with Oracle interMedia Text consists of creating a tablespace for the interMedia Text data dictionary tables and then creating the CTXSYS user name and the interMedia Text data dictionary tables themselves.
To create a tablespace for the interMedia Text data dictionary tables:
To create the CTXSYS user name and the interMedia Text data dictionary tables:
Oracle Spatial makes the storage, retrieval, and manipulation of spatial data easier and more intuitive to users.
One example of spatial data is a road map. A road map is a two-dimensional object that contains points, lines, and polygons representing cities, roads, and political boundaries such as states. A road map represents geographic information. The locations of cities, roads, and political boundaries are projected onto a two-dimensional display or piece of paper, preserving the relative positions and relative distances of the objects.
Review the following table to determine your configuration responsibilities:
Configuring Oracle Spatial:
Oracle Time Series stores and retrieves time-stamped data through object data types (ODTs).
Oracle Time Seriesis a building block for applications, rather than being an end-user application. For example, applications can use this option to process historical data derived from financial market transactions, such as trades of stocks, bonds, and mutual fund shares. From this you can find the opening, closing, low, and high prices for a stock on a specific date; calculate monthly volumes for a stock for a specific year; and derive the 30-day moving average for a stock over a year.
Oracle Time Series also comes as a set of demos that provide a sample demonstration of how the product works.
Review the following table to determine your configuration responsibilities.
If you... | Then... |

Oracle Visual Information Retrieval stores, retrieves, and manipulates image data managed by an Oracle database.
This option provides image storage, content-based retrieval, and format conversion capabilities through an object data type. This option is a building block for various imaging applications, rather than being an end-user application. Some common applications for this option consist of digital art galleries and museums, real estate marketing, document imaging, and stock photo collections for fashion designers and architects, for example.
Oracle Visual Information Retrieval also provides a sample demonstration, showing how an image is extracted from an Oracle database.
Review the following table to determine your configuration responsibilities.
Note: When you select installation of Oracle Visual Information Retrieval, Oracle interMedia is installed automatically since Oracle Visual Information Retrieval cannot function properly without it. |

To configure Oracle Visual Information Retrieval:
Ensure that Oracle interMedia is already configured. Oracle interMedia must be configured before Oracle Visual Information Retrieval. See the configuration instructions for Oracle interMedia on for information about running the ordinst.sql and iminst.sql scripts.
To configure the Oracle Visual Information Retrieval demonstration:
Multi-threaded server mode is also called shared server mode.
If your Oracle database is not configured for multi-threaded server mode, then it is configured for dedicated server mode.
The following table describes the differences between dedicated server mode and multi-threaded server mode.
Additional
Information:
See the Oracle Net8 Administrator's Guide for more information about multi-threaded server mode. |
There are two types of multi-threaded server support:
These types are independent of each other. In other words, you can have any of the following combinations:
The current configuration of your Oracle database depends on how the database was installed.
Multi-threaded server support for IIOP clients is automatically enabled when you install Oracle Java option.
Multi-threaded support for two-task Net8 clients must be enabled manually.
To enable multi-threaded server support for two-task Net8 clients:
Multi-threaded support for two-task Net8 clients must be disabled manually.
To disable multi-threaded server support for two-task Net8 clients:
This section describes how to manually configure Advanced Replication in your Oracle database.
Typically, Advanced Replication is automatically configured during installation. The following figure describes the situations under which Advanced Replication is configured or not configured.
If Advanced Replication is automatically configured, do not follow the instructions in this section. Follow the instructions only if you want to add Advanced Replication to an Oracle database that was not previously configured with this feature.
Configuring advanced replication consists of the following steps:
See the Oracle8i Enterprise Edition Installation for Windows NT CD-ROM insert for Advanced Replication installation requirements.
The following are recommended tablespace requirements for Advanced Replication:
Certain initialization parameter values must be set or added to the INIT.ORA file (recommended values are included) if you use Advanced Replication.
Add these initialization parameters to the master site.
Parameter Name | Recommended Value |
---|---|
SHARED_POOL_SIZE |
At least 10 MB; 15 MB if Java was installed, using the Typical installation option, 50 MB if Java was installed, using the Custom installation option.1 |
DISTRIBUTED_LOCK_TIMEOUT |
300 s |
DISTRIBUTED_TRANSACTIONS |
5 |
GLOBAL_NAMES |
TRUE |
OPEN_LINKS |
4 |
PROCESSES |
Add 9 to current value |
JOB_QUEUE_PROCESSES |
2 (depends on number of n-way sites) |
JOB_QUEUE_INTERVAL |
10 s |
1 Java itself requires a POOL_SIZE parameter of 10 MB. |
Add these initialization parameters for snapshot sites.
Parameter Name | Recommended Value |
---|---|
JOB_QUEUE_PROCESSES |
2 |
JOB_QUEUE_INTERVAL | 60 s |
After setting up the INIT.ORA file with the initialization parameters for Advanced Replication, perform the following steps.
To configure Advanced Replication:
Note:Run the following statement on the master site when setting up updatable snapshot sites:
SVRMGR> GRANT EXECUTE ON DBMSOBJGWRAPPER TO PUBLIC;
The practical limit to the number of master sites an environment can have is 36. The processes SNP0 to SNP9 (total of 10) and SNPA to SNPZ (total of 26) each handle one destination master at a time.
If you use Advanced Replication and intend to set up a large number of replicated objects, monitor the following data dictionary tables with the SQL SELECT command:
If necessary, increase the storage parameters to accommodate the storage requirements of large numbers of replicated objects.
If you are upgrading from a previous version of the Oracle database and want to use advanced replication, you must first complete the upgrade. (See Chapter 5, "Installing, Migrating, and Upgrading Databases" in this guide.)
Because advance replication is an advanced feature, see "Oracle8 Replication" for a presentation of its basic concepts before proceeding. For information about available training, contact Oracle Education.
