OEMM Export of Large Database Models as CSV File Using Rest API Fails With FileNotFoundException (Doc ID 2855982.1)

Last updated on MARCH 15, 2022

Applies to:

Oracle Enterprise Metadata Management - Version 12.2.1.4 and later
Information in this document applies to any platform.

Symptoms


When the Export CSV Rest API is invoked to export a large model, it starts to stream the data to a temporary csv located under <$OMM_Home>/data/files/mm/sessions//database_documentation_export-xxxxx.csv.
Checking the file size, it grows then the file no longer exists. In the logs, OEMM continues with streaming the data to the non-existent temp csv file and once complete then throws a java.io.FileNotFoundException: <$OMM_Home>/data/files/mm/sessions//database_documentation_export-xxxxx.csv.
