Abstract

Described is a method which provides a means of selectively suppressing the writing of objects which follow PC naming conventions to a storage device. The objects are still written to their intermediate staging area, but are suppressed from being written to their final destination. The user defines one or more PC name suffixes which are always write-suppressed. At file open time, this list is checked by the I/O manager and an indicator is set if the file or member should be suppressed. At file close time, if the indicator is on, the object is NOT archived to permanent storage.

Selectable Write Suppression Technique

      Described is a method which provides a means of selectively
suppressing the writing of objects which follow PC naming conventions
to a storage device.  The objects are still written to their
intermediate staging area, but are suppressed from being written to
their final destination. The user defines one or more PC name
suffixes which are always write-suppressed.  At file open time, this
list is checked by the I/O manager and an indicator is set if the
file or member should be suppressed.  At file close time, if the
indicator is on, the object is NOT archived to permanent storage.

      Following provides a detailed description:
1.  A list of PC suffixes, which should cause suppression, is defined
by the user (see the figure).  A suffix can be defined as a fixed
value, a range, or some wildcard expres    sion.  An operator may be
associated with each suffix. ;2.  The list is checked by the I/O
manager at file open time to determine whether or not the file or
member should be sup    pressed. If the file or member matches any of
the criteria in the list, the file is marked for suppression. ;3.  At
file close time, if the file is marked for suppression, it is NOT
archived to permanent storage.
