UPSTREAM/USS Components

UPSTREAM/USS Daemon

The Daemon is the FDR/UPSTREAM Unix Systems Services process. It is a long running process that sits and waits for requests and then processes them. It is suggested that this process be initiated via either an MVS BATCH JOB/Started Task or via the Unix Systems Services system INITTAB.

Daemon Configuration File

The UPSTREAM/USS configuration file contains the product specific definitions required for the USS Daemon. These configuration parameters control the processing of the Daemon from when it is started till it ends. These parameters are discussed in depth in the “USS Process Configuration Parameter Reference”.

Daemon Logging File

The UPSTREAM/USS logging file contains all the messages that have been issued by the UPSTREAM/USS components while it has been operating. This file is named “upstream.log” and is located by default in the directory from which the UPSTREAM/USS daemon is started.

Daemon Message File

This file contains all the FDR/UPSTREAM system messages that it can issue. The messages have a specified format and can be modified, if so desired, by the customer to include additional information. This information will then be displayed when the system message is issued and logged to the logging file.

Daemon Report File

This file contains all of the reporting output based upon the selection criteria specified for the reporting options for a particular UPSTREAM/USS function request. The default file name is “us.rpt”. The file is also located by default in the directory from which the UPSTREAM/USS daemon is started.
