to which exclusive access is available (in other words, when locks are granted). When
an oplock is not available the HP EFS WAN Accelerator does not perform
application-level latency optimizations but still performs Scalable Data Referencing
(SDR) and compression on the data as well as TCP optimizations. If you disable this
feature, the HP EFS WAN Accelerator will still increase WAN performance, but not
as effectively.
Enabling this feature on applications that perform multiple opens on the same file to
complete an operation will result in a performance improvement (for example, CAD
applications):
 Specify a list of extensions you want to optimize using overlapping opens. The
default values are: doc, pdf, ppt, txt, xls.
 Specify a list of extension you do not want to optimize using overlapping opens.
The default values are: ldb, mdb.
NOTE: If a remote user opens a file which is optimized using the overlapping opens feature
and a second user opens the same file they might receive an error if the file fails to go through a
v3.x HP EFS WAN Accelerator or if it does not go through an HP EFS WAN Accelerator (for
example, certain applications that are sent over the LAN). If this occurs, you should disable
overlapping opens for those applications.
The no command options disables CIFs opens.
Syntax [no] protocol cifs oopen {extension [add <ext> | modify <ext> setting <policy> |
delete <ext>] |policy <default policy>}
Parameters
Example
minna (config) # protocol cifs oopen extension modify pdf setting
<policy>
minna (config) #
protocol cifs oopen enable
Description Enable overlapping open.
The no command option disable CIFS opens.
Syntax [no] protocol cifs oopen enable
Parameters None
Example
minna (config) # protocol cifs oopen enable
minna (config) #
extension [add <ext> | modify <ext>
setting <policy> | delete <ext>}
Adds, modifies, or deletes from the overlapping
open special case list files with the specified
extension <ext>. For example, pdf.
policy <default policy> Specifies the default policy for overlapping
opens.
