Container Manager GUI

Standard command-line commands in Solaris software resource management are not supported by the Container Manager software. You should manage the containers from the Container Manager graphical user interface (GUI). The GUI is started from the Java Web Console by using a browser. The following browsers are supported:

• Netscape Navigator^TM 4.7x, 6.2x, and 7.x on Solaris releases 8 and 9

• Netscape Navigator 4.7x, 6.2x, and 7.x on Microsoft Windows (98/2000/XP)

• Mozilla^TM 1.4 and higher

• Internet Explorer 5.0 and higher (including 6.x) on Microsoft Windows (98/2000/XP)

To Start the Container Manager GUI

Steps

1. If your UNIX user ID is not present in the /var/opt/SUNWsymon/cfg/esusers file, create this entry.

   You must also be assigned to either esadm or esdomadm group.

   For instructions about creating an entry and assigning to a group, see Setting Up Users in Sun Management Center 3.6 Installation and Configuration Guide.

2. Start a browser.

   For a list of supported browsers, see Container Manager GUI.

3. To reach the Container Manager GUI, type:

   https://sunmc-server_machine_name:6789/containers

   The Java Web Console login page appears.

   Figure 3–3 Java Web Console Login Page

   
   

   If the login page does not appear, you might need to restart Java Web Console. For instructions, see To Restart Java Web Console.

   ---

   Tip –

   If you reach the Console page, click the Solaris Container Manager 3.6.1 link beneath the Systems section to access the GUI.

   ---

4. Log in to the Java Web Console by using your UNIX user ID and password.

   The Container Manager GUI appears. The screen has three tabs: Hosts, Containers, and Open Alarms.

To Restart Java Web Console

If you are unable to access the Java Web Console, use this command to restart it.

Step

As superuser (su -), restart the Java Web Console by typing:

# /usr/sbin/smcwebserver restart

Hosts View

The Hosts view organizes information from the host perspective. All agent machines that you are managing appear in the navigation window. The resource pools that are available for each host are shown when you click the expansion triangle beside the host name. You can also manage the containers that are associated with the host from this view.

All agent hosts that have the software installed are automatically discovered and added to the Hosts view. This view is accessed from the left tab in the navigation window. All agent hosts that are discovered are initially placed under a default group titled Hosts. You can further organize this view by creating new groups and moving the hosts to relevant groups.

---

Note –

Only those agent machines that are part of the Sun Management Center server context and that have Solaris Container Manager 3.6 installed are loaded into the Hosts view. For more information about server context, see Sun Management Center Architecture in Sun Management Center 3.6.1 User’s Guide.

---

The tabs and information that are available in the Hosts view are listed in Table 3–1.

Information about every project instance that is associated with a host is listed in the Project table.

The following figure shows the Hosts view with the project table that is associated with the default pool.

Figure 3–5 Sample: Hosts View Showing the Project Table

The Project table provides information about each project, detailing one project per row. The Project table provides the following data:

Project Name

Name of the project

Container Name

Name of the container

Status

Containers View

The Containers view organizes information from the container perspective. All containers and projects appear in the navigation window. Because containers can be used repeatedly to make new projects, you can readily access the containers from this view, as well as perform other management tasks.

After installation and setup are complete, the Containers view automatically adds the Containers group as a default. Containers are managed from the Containers view.

The following figure shows the Containers view.

Figure 3–6 Sample: Containers View Showing the Hosts Associated With the Default Container

The information that is available in the Containers view is listed in Table 3–1.

Organizing Hosts and Containers With Groups

The Hosts view contains the default group Hosts. All hosts that are discovered after installation of the software are placed in this group. Likewise, the Containers view has a default group named Default in which all the default containers of a host are placed. You can create additional groups in each view for organizing the hosts and containers.

You might use groups to organize the ten or hundreds of systems you have in a data center. For example, you might put hosts located together in a group. You might put containers owned by the same customer (internal or external) or department in a group. Likewise, you might put containers with a similar application in a group.

To Create a Container Group or Host Group

Steps

1. If the Container Manager GUI is not already open, access it as described in To Start the Container Manager GUI.

2. Select the appropriate view from the navigation window.

   • For a new container group, select the Containers view. The Container table is displayed in the right pane.

   • For a new host group, select the Hosts view. The Hosts and Groups table is displayed in the right pane.

3. Click the New Group button.

   A dialog box appears.

4. Provide a name for the group, and click OK.

   The name cannot exceed 32 characters.

   The new group appears in the selected view.

To Move a Container or Host to a Different Group

Steps

1. If the Container Manager GUI is not already open, access it as described in To Start the Container Manager GUI.

2. Select the appropriate view from the navigation window.

   • To move a container to a different group, select the Containers view. The Containers table is displayed in the right pane.

   • To move a host to a different group, select the Hosts view. The Hosts and Groups table is displayed in the right pane.

3. To enable the Move button in the table, select the check box for the container or host that is to be moved.

4. In the right pane, click the Move button.

   A dialog box lists the available groups.

5. Select the group to which the container or host is to be moved.

6. Click OK.

   The container or host is moved to the selected group.
