The Enterprise Manager Plug-in for Oracle Unified Directory extends Oracle Enterprise Manager Cloud Control 12 c to add support for monitoring Oracle Unified Directory(OUD) instances.
This chapter contains the following sections:
OUD can function in one of the following three modes:
As an LDAP directory server instance, used to contain data
As an LDAP proxy server instance, where the server acts as an interface between the client and the directory server or servers that contain the data
As a replication gateway instance between OUD and Oracle Directory Server Enterprise Edition (ODSEE)
The Enterprise Manager Plug-in for OUD is provided as an archive that includes three target types, one for each OUD installation mode or type. (See "Deploying the Plug-in" for download information.) Install the plug-in that corresponds to the type of OUD instance that you want to monitor.
This 12.1.0.2 version of the Enterprise Manager Plug-in for OUD enables you to monitor the following:
Oracle Unified Directory 11.1.2.2.0 and later for Directory target instances
Oracle Unified Directory 11.1.2.2.0 and later for Proxy target instances
Oracle Unified Directory 11.1.2.2.0 and later for Replication Gateway target instances
Version 11g Release 2 (11.1.2.1.0) of the Enterprise Manager Plug-in for OUD, formerly named the Oracle System Monitoring Plug-in for OUD for Enterprise Manager 11g Grid Control, is available at http://www.oracle.com/technetwork/oem/downloads/unified-directory-514420.html
.
See the Enterprise Manager Plug-In for Oracle Unified Directory Certification Matrix available on My Oracle Support
.
The certification matrix contains information about supported installation types, platforms, operating systems, databases, JDKs, and third-party products.
Install Enterprise Manager Cloud Control 12c (12.1.0.4) or later with the latest bundle patch. Be sure Oracle Management Service and the Oracle Management Agent are installed. It is recommended that the Oracle Management Agent and the OUD instances be installed on the same host.
For detailed information, see the Enterprise Manager Cloud Control 12c Documentation site http://docs.oracle.com/cd/E24628_01/index.htm
.
Make sure that the Oracle Management Agent can communicate with your Oracle Enterprise Manager Server and can upload data. For example, Agent Availability must be UP, Last Load Time should show a recent date/timestamp, and Last Load Time should be Periodically updated. For information about installing and configuring the Oracle Management Agent, see the Oracle® Enterprise Manager Basic Installation Guide.
This section provides the major steps required to deploy the plug-in. For many of the steps, you will be directed to use the instructions already provided in the Oracle Enterprise Manager Cloud Control Administrator's Guide http://docs.oracle.com/cd/E24628_01/doc.121/e24473/toc.htm
.
To deploy the Plug-in for OUD:
Import the plug-in.
See Section 1.2.1, "Importing the Plug-in Archive."
Deploy the plug-in.
See Section 1.2.3, "Deploying the Plug-in.".
Create a target instance of the plug-in on the Oracle Management Agent.
See Section 1.2.4, "Adding Targets To Monitor".
For detailed instructions, see the "Downloading Plug-ins" chapter in the Enterprise Manager Cloud Control Administrators Guide: http://docs.oracle.com/cd/E24628_01/doc.121/e24473/plugin_mngr.htm#CJGBEAHJ
For detailed instructions to upgrade plugin version 12.1.0.1.0 to 12.1.0.2.0, see the sections "Upgrading Plug-Ins Deployed to Oracle Management Service" and "Upgrading Plug-Ins Deployed to Oracle Management Agent" in the Oracle Enterprise Manager Cloud Control Administrator's Guide.
Deploy the plug-in on the Oracle Unified Directory instances to be monitored. For detailed instructions, see "Deploying Plug-ins to Oracle Management Service" in the Enterprise Manager Cloud Control Administrators Guide: http://docs.oracle.com/cd/E24628_01/doc.121/e24473/plugin_mngr.htm#CJGCDHFG
You can now create a target instance.
Create a target instance of the Enterprise Manager Plug-in for OUD on one or more agents. You must create one target instance for each OUD instance.
On the Setup Menu, choose Add Target > Add Targets Manually.
On the Add Target page, choose the Add Targets Declaratively by Specifying Target Monitoring ProPerties option.
Choose the Target Type and the list of agents to which you deployed the plug-in.
Click Add Manually.
On the Add OUD Instance proPerties page, enter the following values:
OUD Credentials
In the Directory Server Username and Password fields, enter a username and password that will be used by the agent to bind to the server instance. Ensure the password is in the appropriate field.
ProPerties
In the Administration Port field, enter the administration port of the target server instance.
In the Directory Server Host field, enter the fully qualified domain name of the target server instance. For replicated servers, you must provide the same host name that was used when replication was configured.
The Trust All field is set to true by default. This implies that all the certificates that are presented by the server (or servers, in the case of replication) will be accepted automatically. Change this setting if you want to specify different behavior.
(Optional) If you have changed the default setting for the Trust All field, enter a path in the Trust Store Path field.
The agent will use the trust store located in this path to validate the certificates of the administration connector that are presented by the server(s). This path must be readable by the agent (and thus located in a file system that is accessible by the agent). The trust store must contain the public keys of the administration connector certificates. It must be in JKS format and must not be password protected.
Click OK.
This section contains the following topics:
Section 1.3.4, "Summary of Directory Server Instance Monitoring Information"
Section 1.3.5, "Summary of Proxy Server Instance Monitoring Information"
Section 1.3.6, "Summary of Replication Gateway Monitoring Information"

Monitoring information is displayed on various pages in the Enterprise Manager Cloud Control console. You can access these pages through the OUD target instance submenu.
Figure 1-1 Comparison of Target Instance Submenus
Table 1-1 compares submenus for an OUD Directory Server instance, OUD Proxy Server instance, and OUD Replication Gateway instance. All submenus include many identical commands including: Home, Monitoring, Control >, Job Activity, Information Publisher Reports, Configuration >, Compliance >, Target Setup >, Target Sitemap, and Target Information. For each target instance, however, the Home page presents different high-level information based on the target instance type.
In Table 1-1, the following differences are highlighted:
For a Directory Server instance, the submenu provides access to the following information: Performance Summary, Resources Usage, and Replication Overview.
For a Proxy Server instance, the submenu provides access to the following information: Performance Summary, Resources Usage, and Remote Servers.
For a Replication Gateway instance, the submenu provides access to the following information: Resources Usage and Replication Overview.
For all target types, the Monitoring > All Metrics command provides access to a complete list of the monitored metrics for the target instance. The information displayed is determined by the Oracle Unified Directory instance type.
Performance information is provided in terms of averages and rates, depending on the information type. Data is represented in both text and graphical form.
Numerical information and comparative data indicates the most recent sampled data. By default, the Oracle Management Agent gathers a new sample of data every five minutes. Line graphs are constructed by point, with each point representing a collected data.
Alerts are generated, based on specific thresholds that you can configure on the Monitoring > Metrics and Collection Settings page.
The Oracle Unified Directory submenu pages display only a subset of the monitored metrics. The Monitoring > All Metrics command provides access to all the monitored metrics for the target instance.
For example, the Performance Summary page of a directory server page provides information on the about the add
, delete
, modify
, modify DN
, search,
and bind
Operations Performed on the server. The All metrics page also provides Operations information for each LDAP connection handlers, which are not included in the Performance Summary page.
To display the All Metrics page:
On the Oracle Enterprise Manager home page, choose Targets.
The Hosts page is displayed.
Click All Targets in the top menu bar.
Choose the target instance name.
The target instance Home page is displayed.
At the bottom of the Home page, under the Related Links menu, click All Metrics.
The All Metrics page is displayed.
Metrics are organized in logical groups. The following figure illustrates the metrics available when the Operations Read Information group is expanded, and Bind Operations Per Second is selected.
To display details of the metric, click on the metric name. In Figure 1-3, to display information about One Level Search Operations Per Second within the last 24 hours, the One Level Search Operations Per Second metric was chosen from the All Metrics page. A new page dedicated to this metric is displayed.
Figure 1-3 lists the following Statistics: Last Known Value: 0.37, Average Value: 0.14, Low Value: 0.06, High Value: 0.43, Warning Threshold: Not Applicable; Critical Threshold: Not Applicable; Occurrences Before Alert: 0, and Corrective Actions: None. A graph is labeled with metric values ranging from 0.00 to 0.50, and hourly intervals spanning 24 hours. The graph data illustrates activity peaks between the hours of 08AM and 08AM the following day.
Figure 1-3 One Level Search Operations Per Second page
The All Metrics page enables you to specify how you want to view a particular metric. The All Metrics page also provides the ability to compare the metrics against to target instances. Use the View Data field to select a specific time Period for which to display the monitored data. Time Periods for seven days or more also display the minimum, maximum and average values of a metric during that Period.
Metric thresholds enable you to specify when alerts should be generated for a specific monitored metric. For example, if you want to receive an alert when the number of read operations per second exceeds a certain maximum, you can configure a threshold for this metric.
To configure a metric threshold:
From the Home page of the Target Instance menu, go to Monitoring > Metric and Collection Settings.
By default, the list of metrics for which thresholds have been defined is displayed. See Figure 1-4.
From the View list, select All metrics.
Scroll down to locate the metric for which you want to set a threshold.
Enter a value in the Warning Threshold column to specify the point at which you should receive a warning alert.
Enter a value in the Critical Threshold column to specify the point at which you should receive a critical alert.
To change the collection schedule for that metric:
Click the existing value in the Collection Schedule column.
Edit the collection settings, as required.
To specify any corrective behavior that should be taken if the metric reaches the warning threshold or critical threshold:
Click the Edit icon.
On the Monitored Objects pane, click Edit.
On the Corrective Actions pane, click Add next to the threshold for which you want to specify the corrective action.
Follow the steps in the Add Corrective Action wizard.
On the Metrics and Collection Settings page, click OK to save your changes.
Figure 1-4 shows the All Metrics view for a directory server target instance. The view contains two tabs: Metrics and Other Collected Items. The Metrics tab contains a table which lists metrics collected for this directory server instance. For each metric, the following values may be reported: Comparison Operator, Warning Threshold, Critical Threshold, Corrective Actions, and Collections Schedule.
To reconfigure the settings for a metric, click the Edit icon the end of its row.

To uninstall the Enterprise Manager Plug-in for OUD, complete the following tasks:
Remove all target instances of the plug-in.
See Section 1.4.1, "To Remove Target Instances of the Plug-in."
Undeploy the plug-in.
See Section 1.4.2, "Undeploying the Plug-in."
You must remove all target instances of the plug-in before you can undeploy the plug-in. For example, if you have three OUD instances with two instances deployed to one agent and the third instance deployed to a second agent, you must Perform the following tasks:
Remove instance 1 (the target instance) on agent 1.
Remove instance 2 (the second target instance) on agent 1.
Remove instance 3 (the third target instance) on agent 2.
You can then undeploy the plug-in from the Oracle Enterprise Manager Cloud Control.
You can remove a target instance by following this procedure. Note that when you remove a target instance, all corresponding data (monitoring data that has already been collected) is deleted.
For each target instance of the plug-in that you want to remove, complete the following steps:
Select Targets on the navigation bar from the Oracle Enterprise Manager home page.
The Hosts page is displayed.
Select All Targets on the Hosts page.
The All Targets page displays the list of all targets in the Oracle Enterprise Manager Cloud Control including hosts, agents, databases, directory servers and others.
The target instance name is displayed in the Name column.
Click Target Setup > Remove Target to select the target instance name.
Click Remove.
The following message is displayed: "You have chosen to remove target_instance_name (OUD Directory Server, OUD Proxy Server or OUD Replication Gateway). Do you wish to proceed?"
Click Yes. A confirmation message is displayed.
The target instance has now been removed. Repeat these steps to remove any additional target instances of the Enterprise Manager Plug-in for OUD.
When all target instances of the plug-in have been removed, you can undeploy and then delete the Plug-in from the Oracle Enterprise Manager Cloud Control, as described in the following sections.
Follow the detailed instructions in the following sections of the Oracle Enterprise Manager Cloud Control Administrator's Guide:
"Undeploying the Plug-in from Oracle Management Service"
http://docs.oracle.com/cd/E24628_01/doc.121/e24473/plugin_mngr.htm#CJGEIECI

http://docs.oracle.com/cd/E24628_01/doc.121/e24473/plugin_mngr.htm#CJGEFADI
The following limitations Pertain to the JVM Resources Report that is generated for each of the three server types.
The CPU Usage graph is available only if:
The target instance is running on the same host as the Management Agent in which the instance is registered
The target instance and the Management Agent are running with the same access rights
The Non-Heap Usage graph is not accurate (the reported metric is incorrect).
If Oracle Management Agent is running on an HP-UX system, then OUD instances should be installed on a path which is limited to 70 characters.
