1. Which Solaris tools allow a system administrator to remotely manage Solaris 10 OS updates for a
number of remote systems from a centralized server location? (Choose two)
A. /usr/sbin/smpatch
B. /usr/bin/updatemanager
C. /usr/sbin/patchadd
D. /usr/sbin/patchmgr
Answer: AB

 

 

1、 /usr/sbin/smpatch analyze     分析并获得一个需要安装的补丁列表
2、 /usr/sbin/smpatch download 下载分析过的补丁列表到本地主机（如果你想重用这些补丁的话）
3、/usr/sbin/smpatch update       安装这些下载好的补丁

更详细的描述请参考 smpatch的手册页

analyze
         Analyzes a system to generate a list of the  appropriate
         updates.

download
         Downloads updates from the Sun update server to  a  sys-
         tem.  You  can optionally specify which updates to down-
         load. You can also specify the  name  of  a  system  and
         download the appropriate updates to that system.


update
         Updates a single local  or  remote  system  by  applying
         appropriate  updates.  This subcommand analyzes the sys-
         tem, then downloads the appropriate updates from the Sun
         update  server to your system. After the availability of
         the updates has been confirmed, the updates are  applied
         based on the update policy.

升级 in Linux and Solaris has different meaning.

In Solaris, 升级 normally means "big change", such as upgrade Solaris 9 to Solaris 10, or Solaris 10 U1 to Solaris update U4 etc.  升级 are normally done through re-install or Solaris live update.

In you are making "small changes" such as individual package changes or kernel improvements, it is called patching. Patching can be done by patchadd or smpatch commands.

Solaris pkginfo, pkgadd, pkfrm and pkgchk commands are similar to Linux rpm command. For example, if you want to find the apache package version, you can do:
pkginfo |grep -i apache
pkginfo -l SUNWapchr

 

-----------------------

一般日常性的更新操作（其实主要就是补丁），可以用斑竹补充的那些命令，或者/usr/bin/updatemanager.

对于升级，看文档的时候知道这样一个命令luupgrade，可以参考。除此之外，我就只知道从光盘启动，选择安装方式为 upgrade。

Maintenance Commands                                luupgrade(1M)

NAME
     luupgrade - installs, upgrades, and performs other functions
     on software on a boot environment

SYNOPSIS
     /usr/sbin/luupgrade [-iIufpPtTcC] [options]

DESCRIPTION
     The luupgrade command is part of a suite  of  commands  that
     make  up  the  Live Upgrade feature of the Solaris operating
     environment. See live_upgrade(5) for a  description  of  the
     Live Upgrade feature.

     The luupgrade command enables you to install software  on  a
     specified  boot  environment  (BE).  Specifically, luupgrade
     performs the following functions:

       o  Upgrades an operating system image on a BE (-u option).
          The  source for the image can be any valid Solaris ins-
          tallation medium, including a Solaris Flash archive.

       o  Extract a Solaris Flash archive onto a BE (-f  option).
          (See flar(1M).)

       o  Add a package to (-p) or remove a package from  (-P)  a
          BE.

       o  Add a patch to (-t) or remove a patch from (-T) a BE.

       o  Check (-C) or obtain information about (-I) packages.

       o  Check an operating system installation medium (-c).

     Before using luupgrade, you must have created  a  BE,  using
     either  the  lucreate(1M)  command or lu(1M), the FMLI-based
     user interface. You can upgrade  only  BEs  other  than  the
     current BE.

     The functions described in the preceding list each  has  its
     own  set of options, which are described separately for each
     function.

     Note that, for successful completion of an luupgrade  opera-
     tion,  the  status  of a BE must be complete, as reported by
     lustatus(1M). Also, the BE must not have  any  mounted  disk
     slices, mounted either with lumount(1M) or mount(1M).

     luupgrade allows you to install an  operating  system  image
     from  a different marketing release of the Solaris operating
     system from the release running on the  machine  from  which
     you   invoke  luupgrade.
