Using the DB2 LOAD Utility to Load Bulk Data

Using the DB2 LOAD Utility to Load Bulk Data

You can use the DB2 LOAD utility to efficiently load large amounts of data to DB2 tables that PowerExchange or PowerCenter has read from data sources. PowerExchange includes JCL and control card templates for running the DB2 LOAD utility. PowerCenter uses PowerExchange Client for PowerCenter (PWXPC) connections to communicate with PowerExchange to implement the bulk data movement.
Depending on how you configure PWXPC connection attributes, PowerExchange can perform the following functions for the DB2 LOAD utility:
  • Produce customized JCL and load cards for running the LOAD utility, generate a data file that contains the data to be loaded, and automatically submit the bulk load job to load data to the target.
  • Create only a data file for the DB2 LOAD utility to load. In this case, you must run the DB2 LOAD utility outside of PowerExchange. You can submit the job manually, or use a job scheduler or the PowerExchange DTLREXE utility.
Alternatively, you can use relational connections with the PowerExchange ODBC drivers. However, Informatica recommends that you use PWXPC connections. In general, PWXPC provides additional functionality, reliability, and performance.
Usually, a bulk data load operation runs either as a task in the PowerExchange Listener or as a separate job that the PowerExchange Listener submits. As an alternative, you can run the bulk data load as a netport job. This strategy is useful if you expect PowerExchange to generate very large load data sets for the LOAD utility and you want to store these data sets on tape. You can configure a netport job to wait for tape mounts.
