Typical record sequences

The life cycle of a file in a file system is recorded in the FCL file from creation to deletion. The following is a typical sequence of FCL records written to the log for creating an FCL file:

VX_FCL_CREATE

VX_FCL_FILEOPEN (if tracking file opens is enabled)

VX_FCL_DATA_EXTNDWRITE

VX_FCL_IMODE_CHG

When writing a file, one of the following FCL records is written to the log for every write operation. The record depends on whether the write is past the current end of the file or within the file.

VX_FCL_DATA_EXTNDWRITE

VX_FCL_DATA_OVERWRITE

The following shows a typical sequence of FCL records written to the log, when file "a" is renamed to "b" and both files are in the file system:
VX FCL_UNLINK (for file "b" if it already exists)

VX_FCL_RENAME (for rename from "a" to "b")
