FUP Commands
PARTONLY
purges data in any primary or secondary extents of partitioned files that reside in
fileset-list. If you omit PARTONLY, data is purged from all partitions of
partitioned files—but only if the primary partitions of the files reside in
fileset-list.

PURGEDATA Guidelines


To use PURGEDATA and purge data from a file, you must have write access to
that file or be a super-group user (255, n).

If you try to purge data from an audited file, TMF must be running, and the disk
containing the file must be enabled for TMF.

For a PURGEDATA operation, the FUP process tries to open the specified file with
exclusive access. If the file cannot be opened with exclusive access, the
PURGEDATA command fails; for example, if the file is already open.

The CLEARONPURGE option set with the FUP SECURE command has no effect
on PURGEDATA. After the PURGEDATA command is executed, the data is
physically present on the disk (but inaccessible) until it is overwritten by new data
or deallocated with the DEALLOCATE command.

PURGEDATA cannot purge SQL files that are not SQL object files. Instead, you
must use SQLCI PURGEDATA.

PURGEDATA Example

To logically purge the data from MYFILE in the current default subvolume:
-PURGEDATA MYFILE
