Steps to Reproduce

  1. Export the pxDecisionResults rule.
  2. Import the rule to another system with 2.45 GB file.

Root Cause

The file upload limit for Pega application is 2 GB.


Perform the following local-change:

Install HFix-42160 (ensure that hadoop-commons-2.7.2.jar and hadoop-auth-2.7.2.jar files are loaded to Pega database using the Import wizard). This allows the use of data flow to import from the source as a dataset of File Repository type and destination as pxDecisionResults.

Perform the below steps:
  1. Private checkout pyinternal When rule for Data-Admin-File-Repository class and change it to false.
  2. Create a File Repository which points to the file directory location (either local on the Pega server or the network file location).
  3. Create the source dataset referencing the file repository created in Step 2.
  4. Create a data flow with the source dataset created in Step 3 and destination dataset as pxDecisionResults (class name Data-Decision-Results for all the records).
  5. Create a batch data flow run to run the data flow created in Step 4.
