If you run a preview more than once,

Data Integration

overwrites the JSON file.

By default, files are stored in the following directory:

<Secure Agent installation directory>/apps/Data_Integration_Server/data/cache/pdo_preview

Files are stored in this directory unless the organization administrator changes the $PMCacheDir property for the

Data Integration

Server service on the Secure Agent. For more information about Secure Agent services,

see the Administrator help

.

Data Integration

purges the directory once every 24 hours. During the purge,

Data Integration

deletes files that are more than 24 hours old.
