ORA-29283: invalid file operation

Steps to Troubleshoot/Solve:

From the error message it is clear that Oracle is unable to write the log file to the corresponding logfile location specified. 

1. Check  the DIRECTORY existence from data dictionary i.e. from dba_directories check whether the directory is physically present in the filesystem. 

2. Check permissions for the user invoking the impdp else grant those permissions

GRANT READ,WRITE on DATA_PUMP_DIR to VIJAY;

3.  Check OS level permissions for DB home owner e.g. oracle  on physical directory. Else use chmod to correct permissions on filesystem.
