PWXCATMY Utility for the Catalog of MySQL Source Table Definitions

PWXCATMY Utility for the Catalog of MySQL Source Table Definitions

The new PWXCATMY utility creates, prepares, and manages the catalog tables that PowerExchange requires for MySQL sources. The utility also reports information from the catalog.
The catalog stores source table definitions. When PowerExchange detects DDL changes of CDC interest to registered source tables, PowerExchange updates the source table definitions in the catalog with the changes. This feature helps avoid errors when PowerExchange reads change data from DDL-updated source tables.
The utility runs on supported Linux or Windows systems.
Use the utility to perform the following types of catalog-related operations:
  • Create the catalog tables, PWXCatTables and PWXCatUpdates, in the MySQL source database or in another local or remote MySQL database.
  • Show the DDL statements for creating the catalog tables.
  • Verify that the catalog tables exist and have the correct format.
  • Create a point-in-time snapshot of the MySQL source table definitions and record the snapshot definitions in the catalog. You must take an initial snapshot of all tables from which change data is captured prior to starting change data capture.
  • Remove, or unregister, source table definitions from the catalog.
  • List the source table names for which table definitions exist in the catalog.
  • Dump the source table definitions that are recorded in the catalog.
  • Drop the catalog tables.
The PWXCATMY command syntax and parameters depend on the type of operation you want to perform.
