Chapter Summary | HP Certified: HP-UX System Administration

You have used HP Software Distributor (SD-UX) in this chapter. You began with learning the structure of HP software packages. Filesets are combination of files. Subproducts are used to logically combine filesets of the same type. Products contain subproducts and filesets . Packages are used to distribute software and can contain full or partial products. The software is stored in software depots. A software depot may be a CD-ROM, a tape, or a directory on a server.

Software is installed with the help of the swinstall command, which can be started in text or graphical interfaces. For listing installed software or the contents of a software depot, you use the swlist command. The swremove command is used for removing software from a software depot or from the system. The swverify command checks the integrity of the installed software. To manage a software depot, you can use the swcopy , swremove , swlist , and swpackage commands. The installed product database (IPD) is used to keep a record of installed or removed software. If new software is installed, it is added to this database. If you remove software using the swremove command, it is removed from the database. To use SD-UX, you need to run the SD-UX daemon named swagentd . This daemon invokes the SD-UX agent, swagent , whenever required. The freedisk command can be used to list and remove any unused software from the system.

Hewlett-Packard releases software updates from time to time. These updates are called patches. Patches are used to add new functionality, remove bugs , or add support for new hardware. The patches can be downloaded from the Hewlett-Packard Web site or the FTP site. Patches are managed in a way similar to general software management.
