Package Deployment

The Package Deployment wizard walks you through the process of scheduling the installation of new packages or upgrades of existing packages. The PEM server must have internet access to deploy packages.

Please note: the Package Deployment wizard is deprecated, and will not be available in future releases of PEM.

Before invoking the Package Deployment wizard, you must modify the PEM agent configuration file and restart the agent; first on the server, and then on each system where packages will be deployed.

• On Linux, modify the agent.cfg file, setting the allow_package_management property to true. The configuration file is located in: /opt/PEM/agent/etc
• On Windows, use the Registry Editor to modify the registry entry for the agent, setting the value of the AllowPackageManagement property to true. The entry is located in: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\EnterpriseDB\PEM\agent

After modifying the agent configuration properties, you must restart the PEM agent.

• On a Linux host, you can use the service command:

  service pemagent restart

• On a Windows host, use the Services dialog to restart the PEM agent service:

  Postgres Enterprise Manager - pemAgent

After enabling package management and restarting the agents, you should also confirm that agent-level probes are enabled on the host of the PEM server, and on any system on which a package will be deployed. To access the Manage Probes tab, highlight the name of the PEM agent in the PEM client tree control, and select Manage Probes... from the Management menu. The following probes must be enabled:

• the Package Catalog probe on the PEM server host.
• the Installed Packages probe on any system on which you wish to install packages.

Then, to open the Package Deployment wizard, select Package Deployment... from the Management menu. The Package Deployment wizard Welcome... dialog opens.

Click Next to continue.

The deployment mode selection dialog

Use the radio buttons on the Deployment Mode Selection dialog to specify the type of deployment that you are scheduling:

• Select the New Package Installation radio button to schedule the installation of a package that has not been previously installed on the server. This is the default.
• Select the Upgrade Packages radio button to schedule an upgrade of packages that are currently installed on the server.

When you’ve made a selection, click Next to continue.

Installing a New Package

If you select New Package Installation on the Deployment Mode Selection dialog, the Package Deployment wizard opens the Agent/Server Selection dialog, allowing you to specify the agents and servers on which the new applications will be installed.

Specify the target Agents and Servers

Expand the tree control, and check the box next to each server on which you wish to install a new package and click Next.

The New Packages Installation dialog opens.

Select which applications are to be installed

Expand the tree control to review a list of applications that are available for installation. Check the box next to an application name to mark the application for installation. Note that the Package Deployment wizard will automatically check the boxes next to any supporting applications required by the applications you select.

When you’ve selected all of the packages you wish to add, click Next to continue.

Specify installation options

Review the list of packages that will be installed, and (if prompted) provide any options requested. Click Next to continue.

Starting the installer download

Click the Start Download button on the Download Packages dialog to instruct the Package Deployment wizard to download application installers. During the download, you can click the Cancel Download button to abort the batch download. When the download completes, click Next.

The Package Deployment scheduling dialog

Use the options on the scheduling dialog to schedule an installation time for the new packages:

• Set the slider next to Deploy Now to Yes to instruct the respective PEM agents to install the downloaded packages immediately. Please note that if a package requires a server restart, current user sessions may be interrupted.
• Set the slider next to Deploy Now to No and use the Time selector to specify a later date and time that you would like the package installation to begin.

Click Finish to install the downloaded packages or schedule the installation and exit the package deployment wizard.

If you have scheduled an installation for a later date/time, the scheduled task will be displayed on the Scheduled Tasks tab. To open the Scheduled Tasks tab, select Scheduled Tasks... from the Management` menu.

The Scheduled Tasks tab

Reviewing Scheduled Tasks

The Scheduled Tasks tab features a legend, displaying the icons that identify the status of each task. The Manage Tasks table displays a list of tasks that are pending execution or recently completed.

Set Show system tasks? to Yes to display system tasks; if it is set to No, only user-defined tasks are displayed. System tasks are displayed with a grey background, and may not be modified.

Highlight the name of a user-defined task and select the Edit icon to access detailed information about the selected task:

• Use the Steps drop-down to view a list of the steps performed during the selected task.
• The Status field lists the status of the current task.
• The Enabled? switch displays Yes if the task is enabled; No if the task is disabled.
• The Name field displays the name of the task.
• The Agent field displays the name of the agent responsible for executing the task.
• The Last run field displays the date and time of the last execution of the task.
• The Next run field displays the date and time of the next scheduled execution of the task.
• The Created field displays the date and time that the task was defined.

To remove a task, click the Delete icon located to the left of a task’s name. The task will be marked for deletion, and removed when the tab refreshes.

Upgrading an Installed Package

If you select Upgrade Packages on the Deployment Mode Selection dialog, the Package Deployment wizard opens a dialog that allows you to specify which agents and packages will be updated.

Select the packages that will be upgraded

Expand the tree control, and check the box next to package you wish to upgrade. Click Next to continue.

Schedule a time for installation

Use the options on the scheduling dialog to schedule an installation time for the new packages:

• Set the slider next to Deploy Now to Yes to instruct the respective PEM agents to install the downloaded packages immediately. Please note that if a package requires a server restart, current user sessions may be interrupted.
• Set the slider next to Deploy Now to No and use the Time selector to specify a later date and time that you would like the package installation to begin.

Click Finish to install the downloaded packages or schedule the installation and exit the package deployment wizard. If you have scheduled the update for a later date/time, the scheduled task will be included on the Scheduled Tasks dialog (accessed through the Scheduled Tasks... menu selection on the agent’s context menu).
