DNFS_BATCH_SIZE

Property	Description
Parameter type	Integer
Default value	4096
Modifiable	No
Range of values	0 - 4096
Basic	No

DNFS_BATCH_SIZE controls the number of asynchronous I/O's that can be queued by an Oracle process when Direct NFS Client is enabled. In environments where the NFS server cannot handle a large number of outstanding asynchronous I/O requests, use this parameter to limit the number of I/O's issued by an Oracle foreground process. The recommended setting for this parameter is to start at 128 and increase or decrease it based on NFS server performance.

Note:

The DNFS_BATCH_SIZE initialization parameter is available starting with Oracle Database 11g Release 2 (11.2.0.4).
