Symptoms
All concurrent requests that run REPORTS are printing the following warning in the request log.
REP-0004: Warning: Unable to open user preference file.
Cause
This message occurs when the concurrent process attempts to open the Oracle Reports executable and your local preference file cannot be found or opened. This is just a warning, so the request will continue to run even if this occurs.
Solution
To resolve the warning, copy the prefs.ora file from your Reports Builder $ORACLE_HOME/tools/admin/ directory into the Applications $HOME directory.
Example:
Copy of the file prefs.ora in the directory /sharp01/prod/apps/tech_st/10.1.2/tools/admin to the directory /home/appprod/.
NOTE:
For a report developed by xml publisher getting the same error, create /HDDATA/xml_tmp directory (environment dependent) on the system server after checking Administration from XML Publisher Administrator responsibility -> Configuration -> General -> Temporary directory column is /HDDATA/xml_tmp.
