Output Files and Caches

Output Files and Caches

The PowerCenter Integration Service process generates output files when you run workflows and sessions. By default, the PowerCenter Integration Service logs status and error messages to log event files. Log event files are binary files that the Log Manager uses to display log events. During each session, the PowerCenter Integration Service also creates a reject file. Depending on transformation cache settings and target types, the PowerCenter Integration Service may create additional files as well.
The PowerCenter Integration Service stores output files and caches based on the service process variable settings. Generate output files and caches in a specified directory by setting service process variables in the session or workflow properties, PowerCenter Integration Service properties, a parameter file, or an operating system profile.
If you define service process variables in more than one place, the PowerCenter Integration Service reviews the precedence of each setting to determine which service process variable setting to use:
  1. PowerCenter Integration Service process properties. Service process variables set in the PowerCenter Integration Service process properties contain the default setting.
  2. Operating system profile. Service process variables set in an operating system profile override service process variables set in the PowerCenter Integration Service properties. If you use operating system profiles, the PowerCenter Integration Service saves workflow recovery files to the $PMStorageDir configured in the PowerCenter Integration Service process properties. The PowerCenter Integration Service saves session recovery files to the $PMStorageDir configured in the operating system profile.
  3. Parameter file. Service process variables set in parameter files override service process variables set in the PowerCenter Integration Service process properties or an operating system profile.
  4. Session or workflow properties. Service process variables set in the session or workflow properties override service process variables set in the PowerCenter Integration Service properties, a parameter file, or an operating system profile.
For example, if you set the $PMSessionLogFile in the operating system profile and in the session properties, the PowerCenter Integration Service uses the location specified in the session properties.
The PowerCenter Integration Service creates the following output files:
  • Workflow log
  • Session log
  • Session details file
  • Performance details file
  • Reject files
  • Row error logs
  • Recovery tables and files
  • Control file
  • Post-session email
  • Output file
  • Cache files
When the PowerCenter Integration Service process on UNIX creates any file other than a recovery file, it sets the file permissions according to the umask of the shell that starts the PowerCenter Integration Service process. For example, when the umask of the shell that starts the PowerCenter Integration Service process is 022, the PowerCenter 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 PowerCenter Integration Service process and then restart it.
The PowerCenter Integration Service process on UNIX creates recovery files with rw------- permissions.
The PowerCenter Integration Service process on Windows creates files with read and write permissions.
