Determining Output

The first three options in the Span parameter file determine where Span writes its output. There are three types of Span output, and you can specify the same or different locations for each output type, as follows:

  • EXTRACTS—These output files contain the records that Span gathers from the DMSII database during the clone.
  • FIXUPS—These output files contain the records that are recorded in the audit trail during the extraction phase of cloning. Fixup records are any update records that are written to the audit file while cloning takes place. If the database was not updated during the extraction phase, there will be no FIXUPS files.
  • UPDATES—These output files contain the update records that Span retrieved from the audit files since the end of the fixup phase.

To direct the output files to the same location, specify the location for the UPDATES option and leave the other two options (EXTRACTS and FIXUPS) blank. In this case, all output is written to the location specified by UPDATES.

Note, however, that the filename and devicename parts of the EXTRACTS, FIXUPS, and UPDATES options default separately, as in the following examples:

Example 1

In this example, all UPDATES, FIXUPS, and EXTRACTS files are named with the file title nodes/filename and are written to DISK.

EXTRACTS

FIXUPS

UPDATES nodes/filename ON DISK

Example 2

In this example, the UPDATES and FIXUPS files are named with the file title nodes/filename and are written to DISK. The EXTRACTS files are named with the file title nodes/filename but are written to TAPE.

EXTRACTS ON TAPE

FIXUPS

UPDATES nodes/filename ON DISK

Example 3

In this example, the UPDATES files are named with the file title nodes/filename and are written to DISK. The FIXUPS files are named A/B/= and are written to DISK. The EXTRACTS files are named with the file title nodes/filename but are written to TAPE.

EXTRACTS nodes/filename ON TAPE

FIXUPS A/B/=

UPDATES nodes/filename ON DISK

Example 4

In this example, the UPDATES files are named with the files title nodes/filename and are written to DISK. The FIXUPS files are named nodes/filename and are written to PACK. The EXTRACTS files are named with the file title nodes/filename and are written to TAPE.
