Oracle/Sun consultants recommended the following settings in /etc/system on our database servers with 64G of physical memory:

* ZFS tuning
set zfs:zfs_immediate_write_sz=8000
set zfs:metaslab_df_free_pct=4
set zfs:zfs_nocacheflush=1
set zfs:zfs_vdev_max_pending=32
* limit zfs 16G
set zfs:zfs_arc_max=17179869184

I was think about setting this limit (16G) on my M5000.

Describe how to use application with Amanda APPLICATIONS
This section lists the applications included with Amanda. See the individual man pages for instructions on using them. For complete How-To information, consult the Amanda wiki at http://wiki.zmanda.com. o amgtar(8), - use GNU Tar to backup and restore data. o ampgsql(8), - use PostgreSQL's continuous WAL archiving. o amraw(8), - use open and read to read the data. o amsamba(8), - use smbclient to backup and restore data. o amstar(8), - use star to backup and restore data. o amsuntar(8), - use native tar on Solaris to backup and restore data. o amzfs-sendrecv(8), - use zfs to create a snapshot and use 'zfs send' to generate the backup. o amzfs-snapshot(8), - use zfs to create a snapshot and for use with other applications (e.g. amgtar) DEFINING APPLICATIONS
An application is defined in amanda.conf(5) as follows: define application-tool $appconfigname { plugin "$pluginname" property "$PROPERTY_NAME" "$PROPERTY_VALUE" ... } and then referenced in a dumptype as define dumptype $dumptypename { ... program "APPLICATION" application "$appconfigname" } Application properties, like Amanda configuration parameters, are insensitive to case, and - (dash) and _ (underscore) may be used interchangeably.
