Oracle database users

A Management Server 8.0.0 using an Oracle® database makes use of stored procedures in the Oracle database. Starting with Foglight 5.6.2, the procedures are created automatically during the upgrade process. To allow the upgrade process to create the stored procedures, a DBA user must first assign the CREATE PROCEDURE privilege to the database user used by Foglight.

To assign the CREATE PROCEDURE privilege to the database user:
•
Execute the following command:
GRANT CREATE PROCEDURE TO <foglight>
where <foglight> is the name of the database user used by the Foglight application

If the upgrade process is run without assigning the CREATE PROCEDURE privilege to the Oracle database user, the database upgrade will fail with the following error:

The Oracle database user has not been assigned the CREATE PROCEDURE privilege.

Once the CREATE PROCEDURE privilege is assigned to the database user, the database upgrade process can be run manually by invoking the foglight_db_upgrade script.

Upgrade the Foglight Agent Manager

This section describes the procedure for upgrading the Foglight Agent Manager (FglAM). The latest version of the Agent Manager is 8.0.0.

Remote updates of the Agent Manager are deployed from the Management Server. Local access to Agent Manager clients is typically not required to perform an upgrade.

 
* 
IMPORTANT: You cannot use the Agent Manager installer to upgrade. You must upgrade the Agent Manager through the Foglight Cartridge Inventory dashboard.

Upgrade the Agent Manager

To upgrade the Agent Manager to the latest version:
1
Navigate to Dashboards > Administration > Cartridges > Cartridge Inventory.
2
On the Installed Cartridges tab of the Cartridge Inventory dashboard, click Install Cartridge.
3
In the Install Cartridge dialog box, click Browse to locate the .car file you require to upgrade the Agent Manager.
 
4
Ensure that the Enable on Install box is selected.
 
* 
IMPORTANT: If the Enable on Install box is not selected, you must manually enable many different cartridges that are contained in the upgrade .car file you are deploying.
5
Click Install Cartridge to install the latest version of the Agent Manager upgrade .car file on the Management Server. Do not delete any of the old .car files.
A progress message appears and, after a few moments, the Operation(s) Complete message box appears, indicating success.
6
Click OK to close the message box.
7
On the navigation panel, click Dashboards > Administration > Agents > Agent Managers.
The Agent Managers dashboard lists connected Agent Managers.
8
Select one or more Agent Managers that you want to upgrade. If you are selecting more than one Agent Manager, they must have the same operating system name.
9
Click Upgrade.
The Deploy Agent Package dialog box opens.
10
From the Package list, select the version to which you want to upgrade, and then click Deploy.
It may take some time for the upgrade process to complete. The more Agent Managers you upgrade, the longer it takes. Once the upgrade is complete, the Agent Manager restarts.
After the “Agent deployment was successful.” message and a green checkmark appear in the Deploying Agent Package box (that is, after the Agent Managers have restarted), you must wait a few additional minutes for the version number of the affected Agent Manager to be updated.
11
On the Agent Managers page, click Refresh.
The version number for the Agent Manager you have modified is updated to the new number, for example 8.0.0.

Upgrade concentrators

When the Agent Manager is deployed using concentrators, all of the concentrators need to be upgraded before the downstream clients are upgraded. Otherwise, when a downstream client is restarted, it sends its upstream concentrator messages in an unknown format, making communication between the two impossible.

Consequently, the Upgrade button on the Agent Hosts dashboard is disabled for downstream clients until all of the upstream concentrators have been upgraded to the latest version.

See the Foglight Agent Manager Installation Guide for more information about running Agent Managers as concentrators.
