A. Tunable Parameters Change History
This section describes new or changed parameters in the Oracle Solaris 10 release.
Oracle Solaris 10 1/13: Oracle Solaris ZFS tunable information is provided in Chapter 3, Oracle Solaris ZFS Tunable Parameters.
Oracle Solaris 10 8/11: The rstchown parameter that was previously set in the /etc/system file is obsolete. If you set this parameter in the /etc/system file, the following error message is displayed:
sorry, variable 'rstchown' is not defined in the 'kernel'
This parameter has been replaced by the ZFS rstchown file system property and a general file system mount option. For more information, see Oracle Solaris ZFS Administration Guide and mount(1M).
Oracle Solaris 10 8/11: This release includes the ngroups_max parameter description. For more information, see ngroups_max.
Solaris 10 10/09: This release includes the zfs_arc_min and zfs_arc_max parameter descriptions. For more information, see zfs_arc_min and zfs_arc_max.
Solaris 10 10/09: Memory locality group parameters are provided in this release. For more information about these parameters, see Locality Group Parameters.
Solaris 10 5/08: The translation storage buffers parameters in the SPARC System Specific Parameters section have been revised to provide better information. In this release, the following parameters have changed:
Solaris 10 8/07: Parameter information was updated to include sun4v systems. For more information, see the following references:
Solaris 10 8/07: The IP instances project enables you to configure a zone as an exclusive-IP zone and assign exclusive access of some LANs or VLANs to that zone.
The previous behavior of shared-IP zones remains the default behavior. The exclusive-IP zone means that all aspects of the TCP/IP state and policy are per exclusive-IP zone, including TCP/IP tunable parameters.
The introduction of the IP instances feature means that the following TCP parameters can only be set in the global zone because they require the PRIV_SYS_NET_CONFIG privilege:
The other TCP, IP, and SCTP parameters and route metrics only require the PRIV_SYS_IP_CONFIG privilege. Each exclusive-IP zone controls its own set of these parameters. For shared-IP zones, TCP, IP, SCTP, and route parameters are controlled by the global zone since the settings of these parameters are shared between the global zone and all shared IP zones.
For more information about using IP instances in Solaris zones, see System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones.
