Oracle Intelligent Storage Protocol
Oracle Intelligent Storage Protocol
Oracle Intelligent Storage Protocol (OISP) enables the Oracle direct NFS (dNFS) client to
encode and pass attributes assoicated with I/O requests to the Oracle ZFS Storage Appliance.
These attributes contain such information as the type of database file that the I/O request is
targeting, the record size of the file, and the identity of the database issuing the I/O request.
The Oracle ZFS Storage Appliance decodes these attributes, using them to simplify database
configuration, increase database performance, and provide observability into the source of I/O
workloads being generated by database clients.
Database Record Size
The Oracle dNFS client can pass the optimal record size based on the type of file for each I/O
request. If a record size is passed, it overrides the "Database record size" property setting on the
share or project. The record size can only be set for newly created files. If a file already exists,
the record size is not changed.
Synchronous Write Bias Hint
The Oracle dNFS client can pass a write bias "hint" associated with write I/O requests that
prompts the Oracle ZFS Storage Appliance to treat I/O requests as either latency sensitive or
throughput oriented. If the hint is passed, it overrides the "Synchronous write bias" property
setting on the share or project.
Analytics Breakdown by Database Name
The Oracle 12c dNFS client can pass the identification of the database (SID) or container
database and pluggable database (SID:SID) responsible for issuing I/O requests. Oracle ZFS
Storage Appliance analytics can display I/O statistics broken down by the SID name(s) of the
database by selecting breakdown or drill by "Application ID."
