修补 AIX 系统 - 修补程序在哪里？怎样申请？

Question

我不是 AIX 专家..... 我被指派将我的系统打补丁到最新的补丁级别。

首先，我从哪里获得 AIX 5.1 和 5.3 的补丁？

其次，它们一般是如何安装的（即命令和程序）。

谢谢你的帮助。

AIX 中的软件维护对于初学者来说是复杂且陌生的。如今，主要的 AIX OS 更新被称为“维护级别”（ML），对这些代码删除的修订被称为“服务包”（SP）。在开始该过程之前，您需要确定您的系统当前处于哪个级别以及您希望升级到哪个级别。使用“oslevel”命令显示系统的软件级别：

$ oslevel
6.1.3.0

Here, oslevel is run without args and displays the base software level, v6.1 ML 3 in the example

To display the SP level use,

$ oslevel -s
6100-03-02-0939

Here, we are at ML 3, SP 2 of AIX 6.1

NOTE: I would recommend reading the latest version of the Services and Support Best Practices doc before going very far as the info given here barely scratches the surface of the subject.

As stated in a previous answer, SUMA is the way to go for quickly gathering OS updates, particularly when one is unfamiliar with navigating the IBM support site and/or AIX maintenance practices in general. With that said, SUMA offers a slew of options and features that can definitely confuse a newbie so here is a short usage scenario:

1. determine the software level that you wish to apply to your systems.
2. use SUMA to download the packages
3. perform a test install of the packages
4. download any missing dependencies using Fix Central (linked in a previous comment) or SUMA itself (SUMA's fileset search can be hit or miss, however)
5. Rinse and repeat until the test comes out clean, then install for real

Here is a sample SUMA command invocation that would download the updates need to bring a v5.3 system to ML 9:

$ suma -x -a RqType=ML -a RqName=5300-09 -a Action=Download

1. -x: perform the SUMA action now rather than scheduling a job using SUMA's built-in schedule
2. -a RqType=ML: set the Request Type to ML
3. -a RqLevel=5300-09: select ML 09 of the AIX 5.3 release
4. -a Action=Download: set the command action to download. This is the default but it is included here for clarity.

By default, SUMA will download packages to the directory /usr/sys/inst.images/installp/ppc. Unless it is interrupted, SUMA will perform an inutoc command in the download directory so there is no need to do so following its run.

Once the software is downloaded, it can be installed using smitty:

$ smitty update_all

or using the "update_all" command:

$ update_all -d /usr/sys/inst.images/installp/ppc -p

“update_all”命令中的“-p”表示“假装”模式。在假装运行干净后将其移除。

希望这可以帮助您入门，但这些代码片段不能替代浏览 AIX 文档。祝你好运。
