|Oracle Solaris Tunable Parameters Reference Manual Oracle Solaris 11 Express 11/10|
This section describes new or changed parameters in the Oracle Solaris 11 Express release.
The ipadm command replaces the ndd command for setting TCP/IP properties. TCP, IP, UDP, and SCTP properties are set as follows:
Display or set an IP property:
# ipadm set-prop -p property-name ipv4 # ipadm set-prop -p property-name ipv6 # ipadm show-prop -p property-name ipv4 # ipadm show-prop -p property-name ipv6
Display or set a TCP property:
# ipadm set-prop -p property-name tcp # ipadm show-prop -p property-name tcp
Display or set a UDP property:
# ipadm set-prop -p property-name udp # ipadm show-prop -p property-name udp
Display or set a SCTP property:
# ipadm set-prop -p property-name sctp # ipadm show-prop -p property-name sctp
For more information, see Overview of Tuning IP Suite Parameters.
This release includes the ngroups_max parameter description. For more information, see ngroups_max.
This release includes the ddi_msix_alloc_limit parameter that can be used to increase the number of MSI-X interrupts that a device instance can allocate. For more information, see ddi_msix_alloc_limit.
A previous version of this manual incorrectly identified the range of the tcp_local_dack_interval parameter as 1 millisecond to 1 minute. The correct range is 10 milliseconds to 1 minute. For more information, see _local_dack_interval.
This release includes the kmem_stackinfo parameter, which can be enabled to monitor kernel thread stack usage. For more information, see kmem_stackinfo.
For information about tuning ZFS file systems, see the following site:
Memory locality group parameters are provided in this release. For more information about these parameters, see Locality Group Parameters.
Parameter information was updated to include sun4v systems. For more information, see the following references:
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.
