How does RC/Extract for Db2 connect to Db2?

RC/Extract uses standard Db2 access methods. It connects to Db2 subsystems using the standard Db2 call attach facility (CAF).

What is the syntax for the EXTRACT command?

The primary command is EXTRACT. It takes parameters for TABLE, WHERE, OUTFILE, and other options to control the extraction process. For example: EXTRACT TABLE(schema.table) WHERE(column > 100) OUTFILE(‘USER.EXTRACT.DATA’)

How does RC/Extract for Db2 use image copies?

RC/Extract can use Fast Unload to directly read image copies, avoiding the need to access the Db2 tables directly. This improves performance and reduces the impact on Db2.

What types of datasets does RC/Extract for Db2 use?

RC/Extract uses standard z/OS datasets for input and output. It supports sequential datasets and VSAM datasets.

What are the business benefits of using RC/Extract for Db2?

RC/Extract can be used to create data subsets for testing or development, reducing the size of test databases and improving performance. It can also be used to archive historical data.

How does RC/Extract for Db2 reduce costs?

By extracting only the necessary data, RC/Extract reduces the storage requirements for test and development environments. It also reduces the time required for data refreshes.

How does RC/Extract for Db2 improve reporting?

RC/Extract allows users to create smaller, more manageable datasets for analysis and reporting. This improves the performance of reporting tools and reduces the time required to generate reports.

How does RC/Extract for Db2 handle security?

RC/Extract relies on Db2 security for data access. Users must have the necessary Db2 privileges to access the tables and views being extracted.

Does RC/Extract for Db2 encrypt data?

RC/Extract does not encrypt data during extraction. Encryption should be implemented at the dataset level using z/OS dataset encryption features.

What auditing and logging capabilities exist?

RC/Extract logs all extraction activity to the z/OS system log. This includes the user ID, the tables extracted, and the WHERE clause used.

How is RC/Extract for Db2 operated?

RC/Extract is typically run as a batch job using JCL. The JCL must include the necessary DD statements for the input and output datasets.

How are errors handled?

RC/Extract uses standard z/OS system messages for error reporting. These messages are written to the job log.

How is RC/Extract for Db2 monitored?

Monitoring is typically done by reviewing the job logs for errors and performance statistics. There is no dedicated monitoring interface.

Product Overview

The architecture of RC/Extract for Db2 centers around its ability to efficiently extract data from Db2 databases on z/OS. The main system components include: the Extraction Engine, the Db2 Interface, and the Dataset Manager. The Extraction Engine parses the `EXTRACT` command and coordinates the data extraction process.

The Db2 Interface uses the Db2 call attach facility (CAF) to connect to Db2 subsystems and execute SQL queries. The Dataset Manager handles the creation and management of output datasets. Communication between these components is primarily through internal program calls and data structures.

DATA')`. RC/Extract uses standard z/OS datasets (sequential and VSAM) for input and output. It integrates with Fast Unload to directly read image copies.

Security relies on Db2's native security mechanisms. Competing products include IBM Data Extract and BMC Extract. RC/Extract distinguishes itself by its streamlined architecture optimized for z/OS environments.

Frequently Asked Questions

What types of data extraction does RC/Extract for Db2 support?

RC/Extract for Db2 extracts data based on SQL WHERE clause criteria. It can extract data from tables and views, and can follow referential constraints to extract related data across multiple tables. It supports various output formats, including sequential files and VSAM datasets.

What are the basic commands and syntax for data extraction?

The EXTRACT command is the primary command. Options include specifying the Db2 subsystem, tables to extract from, WHERE clause for filtering, and output dataset characteristics. For example: EXTRACT TABLE(table_name) WHERE(column_name = 'value') OUTFILE(dataset_name).

How does RC/Extract for Db2 integrate with other tools?

RC/Extract can integrate with Fast Unload for high-speed image copy access. It can also be integrated into batch jobs using JCL and REXX scripts. APIs are not directly exposed.

How is RC/Extract for Db2 configured?

Configuration is primarily done through JCL parameters and control cards. There is no GUI. Parameters control dataset naming, buffer sizes, and other runtime options.
