Keeping Processed Data Sets

SSS2RNPR on means that the JES will not return the data set to the application address space again. The application should treat this as a suggestion (not iron clad) to the JES. The data set could be seen again by the application if:

The JES is restarted
The application is restarted
The operator or another application changes some characteristic.
Selection by token is requested.

SSS2RNPT on means that the JES will not return the data set to the application thread again. A thread begins with the first receipt of a token in field SSS2JEST and ends when the thread calls JES with the SSS2CTRL flag set. Other threads will be able to obtain the data set, provided their selection criteria allow it. The application should treat this as a suggestion (not iron clad) to the JES. The data set could be seen again by the thread if:

The JES is restarted
The operator or another application changes some characteristic
Selection by token is requested.

This SSS2RNPT may be useful for applications that need to hold on to a data set or group of data sets until the data is processed by the requester. It allows for building a "pipeline" of work that is directed to the same processing device or user.

Another way to use the function may be in situations where the system needs to present a list of data sets (from the same job) and keep those data sets on SPOOL for later final inspection. An end user might want to browse all data sets from a job, regardless of output characteristic groupings. If only the KEEP disposition is specified, the same data set may eventually be shown to the application again, thus creating a never ending loop.
