Patching Installed Software

This chapter discusses how to patch the software you have installed.

Some time after you install the ChorusOS 4.0 product, you may choose to patch the installation at some point with Solaris patches provided by Sun. Patches are managed using the patchadd(1M) and patchrm(1M) utilities. See the on-line manual pages for details on how to use the utilities.

Tip -

We recommend that you apply at least the following patches on your host workstation running the Solaris operating environment before applying patches to the ChorusOS 4.0 product:

Solaris 2.6

Apply patch 106125-08.

Solaris 7

Apply patch 107171-04.

In order to download the patch or patches you need for the host workstation, visit http://sunsolve.Sun.COM.

One of the advantages of using the standard Solaris tools to manage installations and patches is that the utilities prevent you from applying patches in the wrong order. One of the constraints of using the standard tools is that the utilities prevent you from applying patches to installations that you have modified "by hand", that is, without using the tools.

Resist the urge to "fix" an installation of the product "by hand".

The ChorusOS configure(1CC) utility detects inconsistently patched installations and refuses to let you build a ChorusOS system image until patch levels for all components involved are equivalent.

When you receive a patch, follow the instructions in the README file provided with the patch. Remember that it is important to apply patches in the correct order.
