skip_alloc is a boolean parameter for the disk resize command. It is supported for devices created on non-NT file systems and on NT raw systems. When skip_alloc is set to be true it allows user to avoid initialization of pages with zeros. The default of skip_alloc is false.
The disk resize syntax is:
disk resize name="device_name"
size=additional_space,
skip_alloc={true|false}
This example does not initialize pages with zeroes for additional space.
disk resize name="dl", size="5G", skip_alloc="true"
With skip_alloc set to true Adaptive Server does not allocate space during disk initialization or extension. Ensure that the allocated space is available for Adaptive Server at the time of allocation.
Use skip_alloc to expedite crash recovery on non-NT file systems and on NT raw systems. Also, using skip_alloc in conjunction with directio creates devices faster and improves durability of updates.
