Software Management Module |
This document explains the features and services available through the Software Management control module on the Sun
Control Station. This module allows you to:
When you click the Software Management menu item on the left, the sub-menu items appear:
For the Installed Software and Needed Software features, click the arrow beside the name of the managed host to view the list of package files installed on the managed host or needed for that host.
In the user manual, the term package file refers to:
V60x server)
The following paragraphs explain the tasks that you can perform with a package file.
Upload allows you to load a package file to a local repository on the control station, from a location that is accessible from your computer. Once the package file is on the control station, if the package file is in the right format and contains the appropriate list data, it can be published or installed.
You can upload a single package file or you can add list of package files whose information is contained in a text file.
Download allows you to download the package file(s) from a remote repository to the local repository on the control station.
Publish allows you to make a package file available for download to external BlueLinQ-enabled servers. A package file can be published from a remote server or the local repository.
If the package file is located on a remote server and you select it to be published, the package file is first downloaded to the local repository on the control station and then made available.
To view the package files published on a Sun Control Station, configure the BlueLinQ settings on the BlueLinQ-enabled server to
http://<fully_qualified_domain_name_of_SCS>/packages/
Unpublish allows you to make a package file unavailable to a BlueLinQ-enabled server.
In this case, the package file is no longer visible to external BlueLinQ-enabled servers but it is still appears in the Packages table. The package file remains in the local repository on the control station.
Install allows you to install package files on selected managed hosts. You can install package files from either a local or remote repository.
If the package file is located on a remote server and you select it to be installed on a managed server, the package file is first downloaded to the local repository on the control station and then installed on the managed host.
Before installing a package file, the control station performs a dependency check and displays a confirmation screen. For more information, see Dependency Checking.
|
Caution - Uninstalling a package file from a host can adversely affect the functioning of the host. |
Uninstall allows you to uninstall a package file from selected managed hosts, if this feature is available for that package file.
When you uninstall a package file, the control station updates the list of installed package files immediately for those hosts.
Package Info allows you to view detailed information for a package file, such as the vendor, a description of the package file, the size of the package file, whether the package file can be uninstalled once it is installed, whether the host needs to be rebooted after a package file is installed and the prerequisite packages for this package file.
Remove allows you to remove a package file from the list of available package files. If the package file is on a remote BlueLinQ server, the entry for that package file is removed from the list of available package files. If the package file is in the local repository on the control station, the entry for that package file is removed from the list of available package files and the package file is deleted from the repository.
If the package file has been "published" on your control station, the package is no longer available to BlueLinQ-enabled servers once you remove it.
If you use the refresh option, a package file located on a remote BlueLinQ server appears again.
|
Note - You cannot delete a package file from a remote BlueLinQ server with the Remove option. |
The Packages sub-menu item allows the user to manage the package files on the remote and local servers. The selector lists all of the software packages known by the Sun Control Station. The software packages can be located locally on the control station itself, on another control station or on a remote BlueLinQ server.
For an explanation of the tasks available under this menu item, see Tasks available in Software Management.

Through the Settings sub-menu item, you can add, modify or remove a remote software server for the Software Management module. The remote software server can be a BlueLinQ server or a YaST Online Update (YOU) server.
The Sun Control Station accesses the remote software servers and displays the available list of package files for the hosts that it manages.
|
Note - The remote software servers listed under this menu item contain software packages for the hosts managed by the Sun Control Station, and not for the control station itself. |
Your Sun Control Station can act as a BlueLinQ server. All BlueLinQ-enabled servers, including other Sun Control Stations, can see package files published on your control station. This allows the control stations to share and distribute the package files more efficiently, and to take full advantage of the "Publish" feature in the Software Management module.
The Sun BlueLinQ server updates.cobalt.com/packages/ provides a list of package files available for your Sun Cobalt server appliances.
To add this server to the list of remote software servers, see Adding a remote software server.
The YaST Online Updater (YOU) feature is the update and patching mechanism that is bundled in the Sun JDS software. The Sun Control Station can act as a mirror of a remote YOU server.
The Remote Software Servers table displays the remote software server(s) that you have configured in the Software Management module. The Software Management module displays all package files available from these servers.
|
Note - The host name of the remote software server(s) that you enter must be resolvable by a Domain Name System (DNS) server that your Sun Control Station accesses. |
The table has three columns; FIGURE 8 shows a sample of this table.
You can sort the list of remote software servers according to the name of the server or the URL address, in ascending or descending order.
Ascending order means from lowest value to the highest value (a-z or 1-9). Descending order means from highest value to the lowest value (z-a or 9-1). By default, the Remote Software Servers table is sorted by server name in ascending order.
In the heading of the column which has been sorted, a triangle icon points down (ascending order) or up (descending order).
Once a remote software server has been added, you can perform various operations on that server. These operations are found in the Actions column of the Remote Software Servers table and are explained further on.

When you launch an Install A Package File task, the Sun Control Station first performs dependency checks on the host you selected to ensure that the selected package file(s) can be installed. This operation verifies three things:
If yes, and if these required package files are available to the control station, they are installed in the correct order; the selected package file is installed afterward.
The control station displays a confirmation screen for you to confirm or cancel the install task.
The install task is an all-or-nothing operation, meaning that all package files are installed on the appropriate host(s) in one operation. If there are any package-file dependencies that cannot be resolved by the Sun Control Station (a red status), the entire install task cannot proceed.
On the confirmation screen, the Patch Install Status table appears at the top.
This table displays the overall status of the install task as a colored circle and icon. If any component in the install task has yellow status, the overall status of the install task is displayed as yellow; if any component has red status, the overall status is red.
Green with checkmark: There are no dependency issues and you can install the package file(s) on the host(s).
Yellow with exclamation mark: There is at least one dependency issue that can be resolved for the package file(s) that you want to install on the host(s). You can proceed with the install task. The control station will first install the necessary package file(s) to resolve the dependency issue(s) on the host(s), and then install the selected package files.
Red with X: There is at least one dependency issue for the selected package file(s) that cannot be resolved by the control station. You cannot proceed with the install task if the status is red.
For a yellow or red status, always view the details in the Install Information by Appliance or Install Information by Patch table that appears below the Patch Install Status table.
FIGURE 12, FIGURE 13, FIGURE 14 and FIGURE 15 show different samples of the dependency-check results on the confirmation screen.
The Install Information by Host table appears by default; FIGURE 12 shows a sample table. The table has the following five columns:
When you view the package files to be installed, a second table of information appears. In this table, you can click on another icon to view all of the information about a package file.
If one of the managed hosts shows a red status, meaning it has dependency issues that the control station cannot resolve, you can remove the host so that the rest of the install task can proceed.
To view the Install Information by Patch table, use the pull-down menu at the top to select View by Patches. FIGURE 13 shows a sample table. The table has the following five columns:
If you notice that all of the selected host(s) display a red status, this table can help identify whether it is a single package file that is causing dependency problems on all of the hosts.
If you can proceed with the install task, you can choose to install the package file(s) immediately or to schedule the installation for a later time.
