DNFS_READBUFFERS

Default: 4

Purpose

The DNFS_READBUFFERS parameter lets you control the number of read buffers used by the Direct NFS Client. The Direct NFS Client is an API that can be implemented by file servers to allow improved performance when an Oracle database accesses files on those servers.

Syntax and Description

DNFS_READBUFFERS=n

Using larger values might compensate for inconsistent I/O from the Direct NFS Client file server, but it may result in increased memory usage.

Restrictions

To use this parameter without also specifying the DNFS_ENABLE parameter, the input file must be larger than 1 GB.

Example

The following example specifies 10 read buffers for use by the Direct NFS Client.

DNFS_READBUFFERS=10
