When a Data Integration Service process generates output or log files, it sets file permissions based on the operating system.
When a Data Integration Service process on UNIX generates an output or log file, it sets the file permissions according to the umask of the shell that starts the Data Integration Service process. For example, when the umask of the shell that starts the Data Integration Service process is 022, the Data Integration Service process creates files with rw-r--r-- permissions. To change the file permissions, you must change the umask of the shell that starts the Data Integration Service process and then restart it.
A Data Integration Service process on Windows generates output and log files with read and write permissions.
