History Files Store Folder
Specify the folder that keeps the temporary file which is created when the request for writing to
the remote disk in the “Asynchronous” mode cannot be recorded in the application queue. When
the communication band runs short, data is recorded up to the limit of the disk space if the limit
of the history file size is not specified. Thus, specifying a folder on the system disk runs out of
the empty space and the system behavior may become unstable. Therefore, if you want to
suspend mirroring when recording data is exceeded a certain size, create a dedicated partition or
specify the limit of the history file size. Do not specify any folder on the cluster partition and data
partition to the history files store folder.
Thread Timeout
This is the time that time-out is occurred when data cannot be transferred to the application queue
from the kernel queue in the mode of “Asynchronous.” When it is timed out, a mirror connect is
cut.
Timeout may occur, if the data transfer to the application queue is delayed due to high load. In
this case, increase the timeout value.
