Write-delete record types

There are four sections in the journal records written for write-delete record types:

v

The FLJB_GENERAL_DATA section,

v

The FLJB_WRITE_DELETE_DATA section, and

v

The two caller data image sections, which consist of:

– FLJB_WDD_BASE_KEY (the length of which is given by

FLJB_WDD_BASE_KEY_LENGTH in FLJB_WRITE_DELETE_DATA)

– FLJB_WDD_PATH_KEY (the length of which is given by

FLJB_WDD_PATH_KEY_LENGTH in FLJB_WRITE_DELETE_DATA).

These sections contain the image of the caller data as the base key, and, if the
data set is a path, the path.

The format of such a record written for write-delete record types is shown in
Figure 81.
