Scheduling Extract rule runs
For more efficient operation, you should schedule run of an Extract rule using a Pega Platform Job Scheduler (for Pega Cloud and on-premises) or from a Windows or UNIX/Linux command-line (for on-premises only). For details, see Using the Job Scheduler rule to extract data with BIX and Running the command-line extract process.
Executing BIX may result in errors or exceptions being reported. These exceptions may relate to syntax errors (in command-line execution), database constraint violations (when exporting to a database), or similar issues. For details, see BIX logging and error handling.
Extract rules can operate on the BLOB column of tables in the PegaRULES database or they
can be used to extract data from tables with no BLOB column. However, when a class table
includes a BLOB (
pzPVStream column), extraction always is performed from
that BLOB value, and not from other database columns. For details, see
If the Extract rule class is a class group, the query on the source database extracts all WorkObject instances of all classes within the class group. If the extract rule class is not a class group, the query on the source database only gets instances of the particular class.
Forward and backward chaining during BIX extract (on-premises applications only)
For on-premises clients, in the prconfig file, a setting governs whether forward and backward chaining are enabled during a BIX extract. You should disable forward and backward chaining for better throughput when running BIX. For details, see Configuring optional prconfig.xml settings.
