TIBCO WebFOCUS Files Under MVS

In this section:

You will come across a variety of files in WebFOCUS. These files fall into three categories: application files, extract files, and work files. This topic contains information about files and ways to define them in the MVS environment.

Some files are automatically allocated by WebFOCUS, but there are times when you must explicitly define a file and its location to WebFOCUS. You can do this by using the DYNAM and ALLOCATE commands. For details on these commands see the TIBCO WebFOCUS® Reporting Server Administration manual.

Referencing Files Under MVS

Reference:

Reference files by ddnames rather than by their fully qualified data set names. Data set names are arbitrary but must conform to the naming standards of your installation.

Dynamically Defining Files Under MVS

You do not have to explicitly define most of your files. WebFOCUS automatically allocates many application files on an as-needed basis, as long as they follow the data set naming conventions. WebFOCUS allocates five primary cylinders and five secondary cylinders for dynamically allocating files. WebFOCUS dynamically allocates work files, but does not automatically define application files. You need to define these files.

WebFOCUS will allocate some or all of the following output or work files as temporary data sets:

You can explicitly allocate files in the server JCL. For more information about allocating files, see your Reporting Server documentation.

Note: Work files should not be allocated in the server JCL.
