An Oracle Solaris instance, which is defined as a boot environment in either a global or a non-global zone, is created and configured during an installation. After installing or creating an Oracle Solaris instance, you can unconfigure and reconfigure the instance by using the new sysconfig utility. This tool replaces the sys-unconfig and sysidtool utilities.
The sysconfig configure command produces similar results to the sys-unconfig command that is used in Oracle Solaris 10. For example:
# sysconfig configure -s This program will re-configure your system. Do you want to continue (y/(n))? y
The following example shows how you would unconfigure a previously configured Oracle Solaris instance and leave it in an unconfigured state:
# sysconfig unconfigure -g system
You can also reconfigure an Oracle Solaris instance by specifying an existing configuration XML profile, as shown in this example:
# sysconfig configure -c profile-name.xml
If you do not specify an existing configuration profile prior to an installation, the SCI tool launches during the installation process. The SCI tool enables you to provide specific configuration information for that Oracle Solaris instance. The SCI tool consists of a series of interactive panels that enable you to provide configuration information as part of a text installation. You can also run the tool on an installed Oracle Solaris system to create a new system configuration profile that is based on specifications that you provide.
Start the SCI tool from the command line as follows:
# sysconfig configure
See sysconfig (1M) and Chapter 6, Unconfiguring or Reconfiguring an Oracle Solaris Instance, in Installing Oracle Solaris 11.2 Systems .
