DTLUAPPL Utility Overview

DTLUAPPL Utility Overview

Use the DTLUAPPL utility to generate restart tokens for CDC sessions and to add, modify, or print application information in the CDEP file. DTLUAPPL can generate restart tokens for all PowerExchange CDC source types and for CDC sessions that use either ODBC or PowerExchange Client for PowerCenter (PWXPC) connections.
Restart tokens determine the point in the change stream at which CDC sessions begin extracting change data. Restart tokens are composed of a pair of sequence and restart token values. The lengths of the token values depend on the data source type and whether you use ODBC or PWXPC.
If you use ODBC connections to extract change data, PowerExchange maintains application names, registrations associated with each application name, and the restart tokens in the CDEP file. When you use the utility to add or modify applications, the utility updates the CDEP file. If an application name entry does not exist when the initial extraction process runs, PowerExchange creates an application entry in the CDEP file. To generate current restart tokens for the initial extraction process, run the utility immediately after target materialization and before any change data has been captured or applied. After the initial extraction process runs, you can use DTLUAPPL to generate current restart tokens for an application.
If you use PWXPC connections to extract change data, the CDEP file is not used. After you materialize the target tables and before you start the CDC session, run DTLUAPPL to generate restart tokens that identify the starting point for extraction processing. Then update the PWXPC restart token file with these generated restart tokens. If you rematerialize target tables for any reason, you can run the utility again to generate current restart tokens.
The utility generates sequence tokens in the format that is used by ODBC extractions. To use generated sequence tokens for a PWXPC session, use the utility to print the sequence and restart token values for the capture registrations associated with the application name. Then add eight zeroes to the end of the printed sequence values.
Alternatively, you can generate current restart tokens from the PowerExchange Navigator. For more information, see the
PowerExchange Navigator User Guide
