System Requirements and Certifications

2-4 Oracle® Fusion Middleware Connectivity and Knowledge Modules Guide for Oracle Data Integrator ■ A specific log file is created by SQLLoader. We recommend looking at this file in case of error. Control Files CTL, Log files LOG, Discard Files DSC and Bad files BAD are placed in the work directory defined in the physical schema of the source files. ■ Using the DIRECT mode requires that Oracle Data integrator Agent run on the target Oracle server machine. The source file must also be on that machine.

2.2.2.2 Using External Tables

This section describes the requirements that must be met before using external tables in Oracle database. ■ The file to be loaded by the External Table command needs to be accessible from the Oracle instance. This file must be located on the file system of the server machine or reachable from a Unique Naming Convention path UNC path or stored locally. ■ For performance reasons, it is recommended to install the Oracle Data Integrator Agent on the target server machine.

2.2.2.3 Using Oracle Streams

This section describes the requirements for using Oracle Streams Journalizing knowledge modules. The following requirements must be met before setting up changed data capture using Oracle Streams: ■ Oracle Streams must be installed on the Oracle Database. ■ The Oracle database must run using a SPFILE only required for AUTO_ CONFIGURATION option. ■ The AQ_TM_PROCESSES option must be either left to the default value, or set to a value different from 0 and 10. ■ The COMPATIBLE option should be set to 10.1 or higher. ■ The database must run in ARCHIVELOG mode. ■ PARALLEL_MAX_SERVERS must be increased in order to take into count the number of Apply and Capture processes. It should be increased at least by 6 for Standalone configuration, 9 for Low-Activity and 21 for High-Activity. ■ UNDO_RETENTION must be set to 3600 at least. ■ STREAMS_POOL_SIZE must be increased by 100MB for Standalone configuration, 236MB for Low-Activity and 548MB for High-Activity. ■ All the columns of the primary key defined in the ODI Model must be part of a SUPPLEMENTAL LOG GROUP. ■ When using the AUTO_CONFIGURATION knowledge module option, all the above requirements are checked and set-up automatically, except some actions that must be set manually. See Using the Streams JKMs for more information. Note: It is recommended to review first the Changed Data Capture chapter in the Oracle Database Data Warehousing Guide, which contains the comprehensive list of requirements for Oracle Streams.
