Key Features (very similar to 13.1.1.1.0):

System Management

Oracle Application Management Pack provides monitoring alerts and notifications for Oracle Application Framework, Concurrent Processing, Forms services, concurrent managers and requests, Oracle Workflow services, Oracle Database, and middle tier/web servers.

Standardize monitoring settings across your Oracle E-Business Suite environments by utilizing templates to initially specify the monitoring settings and apply those to your monitored targets. You can save, edit, and apply these templates across one or more targets. A monitoring template is specified for a particular target type and can only be applied to targets of the same type.

Use the Concurrent Processing dashboard for a complete picture of concurrent processing on your Oracle E-Business Suite system of both current activities as well as usage statistics. Add concurrent programs and managers as user-defined targets and the system will collect metrics on activity and usage for them.

Configuration Management

Oracle Application Management Pack collects and stores the technology configurations of Oracle E-Business Suite to help centralize monitoring and tracking of changes to Oracle E-Business Suite technology stack configurations including host configuration, database configuration, middleware configuration, patches applied, key profile option changes, versions of technology components, and custom object changes.

Compare configurations between two or more Oracle E-Business Suite systems directly or by comparing configuration snapshots taken at different time intervals.

Configuration templates help to standardize the configuration standards across the company and reduce the configuration drift between various Oracle E-Business Suite instances.

Administrators can track changes by setting up notifications when any unauthorized changes occur to technology stack configurations.

Compliance Management

Compliance framework integration allows you to ensure your Oracle E-Business Suite is compliant with your IT audit requirements, as well as industry and regulatory requirements. Compliance Management dashboards show trends and compliance violations. Proactive, real-time compliance monitoring can significantly reduce the operational risk to business.

Change Management

Change Approval Framework

All changes made with Oracle-delivered patches or customizations in Change Management are processed through a change approval mechanism. A multi-level, hierarchical list of approvers can be set up for each Oracle E-Business Suite target. Auditors can review the change requests as welll as the approvals.

Patch Management

Patch recommendations for Oracle E-Business Suite application products and the technology stack components are made for specific Oracle E-Business target instances to help reduce or eliminate the research work by administrators. These patch recommendations help to ensure all Oracle E-Business Suite systems are current with Oracle-recommended patches. You can deploy database and WLS patches by creating Oracle Enterprise Manager patch plans directly from the patch recommendations user interface.

Using the Patch Management dashboard, you can manage all patching activities of your Oracle E-Business Suite instances and view patch worker logs. Patch Manager simplifies the online patching process and reduces human intervention to a great extent, eliminating the need for continuous monitoring of the patching process.

Patch Manager makes it easier for administrators to check for prerequisite patches and to download the patches in offline mode or directly from My Oracle Support.

Customization Management

Create and deploy custom packages across Oracle E-Business Suite instances similar to Oracle-delivered patches. Customization Manager can help ensure all customizations follow Oracle development standards and/or user-defined customization standards specific to your IT organization. Easily integrate Customization Manager with any third-party source code version control software. This feature also supports the creation of National Language Support (NLS) patches.
Customization Manager can discover customizations within your Oracle E-Business Suite systems and provide detailed reports online or in a spreadsheet format. This helps your organization keep track of the inventory of customizations and use the data for further analysis.

Cloning

Automated Cloning allows you to clone your Oracle E-Business Suite applications for testing, training, or development purposes, leveraging the Oracle Enterprise Manager Cloud Control Provisioning Framework. A step-by-step interview guides an administrator through the cloning process and facilitates scheduling of Oracle E-Business Suite instance. Administrators can modify the standard cloning procedure to include pre- or post-custom steps, seamlessly automating their cloning process from beginning to end.

Instance Administration

Administrators can use the Instance Administration user interface when adding and removing (scale in and scale out) application services, application nodes, and managed servers.

Getting Started with OEM 13cR2 (13.2.2.0.0) Enterprise Manager

OEM13c Release 2 Enterprise Manager Summary Page

Relatively easy installation, a new learning curve to master for post-installation maintenance and patching.
The principal changes in Release 2 of 13c are the segregation of the Cloud Management Services plugins (and related functionality) to specific licensable plugin components – namely:

• Cloud Services Management – used for provisioning, allocation, and administration (think “infrastructure”) of Oracle Public Cloud-based resources (databases, development tools, middleware, etc.)
• Oracle Cloud Application – a portal punch-out to access Oracle Cloud-based applications such as hosted e-Business Suite, Cloud Content Management, Cloud SOA Suite, Cloud Identity Management, etc. (think “apps”.)
• Cloud Framework – a repackaging of the EM OMS framework components, and the only portion of the “cloud” components included in the base OEM licensing.
  Installation guide: http://www.oracle.com/technetwork/oem/grid-control/documentation/oem-091904.html

Cloud Management related plugins for OEM13cR2

This proof-of-concept testbed system was based upon the latest available installer set – Oracle Enterprise Manager Cloud Control 13c Release 2 Plug-in Update 1 (13.2.0.0) – we happen to be testing backwards-compatibility with some 10g databases before committing to the upgrade.  Direct (out-of-place) upgrades are supported for version of EM 12.1.0.4 and newer.

http://www.oracle.com/technetwork/oem/enterprise-manager/downloads

Fusion Middleware in this release is Weblogic 12.1.3
The host system is built upon Windows Server 2012 R2, single-tier, 16GB RAM, 2 cores, also hosting the OMS repository database in a 12.2.0.1.0 EE installation.  Since the DB Templates provided seemed to be specific for a 12.1.x database (and errors out in certain steps during the build), I simply created a generic database from the standard template with the pre-requisite parameter settings (e.g. _allow_insert_with_update_check=TRUE; sessions > 300; shared_pool_size (10% of SGA); etc.) , and pre-created the required tablespaces:

MGMT_AD4J_TS
MGMT_ECM_DEPOT_TS
MGMT_TABLESPACE

  During the installation, the (Oracle Universal Installer) OUI will create the following new users assigned to these tablespaces:

Open:
SYSMAN
SYSMAN_TYPES
SYSMAN_BIPLATFORM
SYSMAN_STB
SYSMAN_OPSS
SYSMAN_MDS
MGMT_VIEW

Expired & Locked:
CLOUD_ENGINE_USER
CLOUD_SWLIB_USER
EUS_ENGINE_USER
SYSMAN_RO

The standard download set includes a single executable file (.exe or .bin) and several additional ZIP archives.  These are to be staged in a single directory, and the ZIP files do NOT need to be pre-extracted.

Overall, the installation was straight-forward and as-documented (despite this being a Windows installation – which usually has its own quirks.) The portion that I feel has the steepest learning curve is post-installation maintenance, and particularly patching. The new tool in 13c, the OMSpatcher (Patchset 19999993 – think of it as a Java wrapper for opatch) was really designed for use specficially in a cloud-based environment and hasn’t been completely polished for use on-premise in smaller installations.

For example, it is designed to rely upon an active Weblogic AdminServer to instantiate it’s requests for inventory versioning information and component availability for patching. But if any of those components are actually in-use by the AdminServer itself, it will tend to fail to apply, and instead provide a lengthy step-by-step instruction set of how to accomplish all of the steps manually. Depending on the complexity of your OEM setup (e.g. the number of registered plugins and target types) this could take over an hour to get the patching utility to fail and then provide the manual steps.

The OEM-specific version of OPatch (Patchset 6880880) is quite different than its predecessors.  While the OMSPatcher uses the prior “unzip into the existing Oracle Home” installation technique, the OPatch utility itself now is a Java installer that relies on the OUI to allow updating of component versioning and inventory adjustments. Most importantly, you will need to “install” the new version of OPatch before being allowed to continue with your planned patching:

$JAVA_PATH\java -jar $PATCH_STAGE\6880880\opatch_generic.jar -silent oracle_home=$ORACLE_HOME (being updated for OPatch)

This OPatch update needs to be applied (before patching) to every Oracle Home using 13c technology (the OMS home, the Agent Home, other FMW homes at version 12.1.3 or newer, etc.)

See MOS EM 13c: How to Apply a Patch to the Enterprise Manager 13c Cloud Control OMS Oracle Home (Doc ID 2091619.1) for details about making an OMSPatcher property file, and why you want to create one.

Final steps executed:
Build general purpose 12.2.0.1.0 database with new tablespaces.
Install Oracle Enterprise Manager Cloud Control 13c Release 2 Plug-in Update 1 (13.2.0.0)
Patch 19999993: EM OMSPatcher latest version 13.8.0.0.2 (unzip to ORACLE_HOME)
Patch 6880880: EM OPatch latest version 13.9.0.0.0 (both OMS and Agent)

cd $PATCH_STAGE\<patch#>
$FMW_HOME\OMSPatcher\omspatcher apply -analyze -property_file 
$FMW_HOME\OMSPatcher\omspatcher apply -property_file  [OMS_DISABLE_HOST_CHECK=true  -- a useful option added to deal with virtual host names]

DataGuard and OEM 12c OMS DB Failover Configuration

# When Oracle DataGuard high-availability for the OMS database is configured using the OEM DataGuard Administration Wizard, and fast-start failover is configured, fail-overs automatically rename the standby as primary, and vice-versa and establish the change-over in roles.  While this accomplishes the database staying online and available on the secondary host (or all other databases in the DG group), the Enterprise Manager OMS must be told how to connect to it – preferably transparently.

# DataGuard OMS Registration

Investigating an OEM 12c E-Business Suite Alert (AMS 12.1.0.x)

OEM 12 Home Page

The Applications Management Suite plug-in for Oracle Enterprise Manager simplifies discovery of the myriad of subtargets that make up an Oracle E-Business Suite instance.  Correspondingly, the number of alerts sent out can rise dramatically because of the inter-relationships between the components.

For example, the outage of a single Apache process triggers all of the following associated targets also to flag as a service Down status:

INSTANCE-Oracle E-Business Suite
INSTANCE-Infrastructure INSTANCE_host-APPL_TOP Context
HTTP_Server

The number of downed targets increases if a subcomponent of a primary component (such as a single JVM thread under the OACore process) experiences an outage.

This is a simple walk-through of navigating one of the e-mail alerts to start figuring out what happened.

The e-mail alert looks like this:

From: OEM12 Burbank
Sent: Monday, December 07, 2015 8:30 AM
To: DBAs
Subject: EM Event: Fatal:INSTANCE-Oracle E-Business Suite – Target is down; 1 member is down: INSTANCE_EBS Availability System

Host=hostname
Target type=Oracle E-Business Suite
Target name=INSTANCE-Oracle E-Business Suite
Categories=Availability
Message=Target is down; 1 member is down: INSTANCE_EBS Availability System
Severity=Fatal
Event reported time=Dec 7, 2015 8:29:14 AM PST
Target Lifecycle Status=Production
Operating System=Linux
Platform=x86_64
Associated Incident Id=390885
Associated Incident Status=New
Associated Incident Owner=
Associated Incident Acknowledged By Owner=No
Associated Incident Priority=None
Associated Incident Escalation Level=0
Event Type=Target Availability
Event name=Status
Availability status=Down
Root Cause Analysis Status=Symptom
Rule Name=EBS Notifications,Rule_EBS_Notifications
(to get notified, you set up Rule Sets that tell OEM when and what to notify you about)
Rule Owner=DBA
Update Details:
Target is down; 1 member is down: INSTANCE_EBS Availability System
Incident created by rule (Name = Incident management rule set for all targets, Incident creation rule for a Target Down availability status [System generated rule]).

---

To investigate an event alert, click on the Associated Incident ID (e.g. the 390885 which on your system will be a URL taking you into OEM) which will take you to the associated Incident Summary page.

Click on Related Events to investigate what raised the event alert (there may be more than one cause):

OEM 12c AMS 12.1.0.4 – Incident Details

From the screen, it shows the red mark on PRODARMK-Infrastructure PRODARMK_ascopofinm01-APPL_TOP Context (Oracle E-Business Suite Node).

Click on that link in the list of Targets.

Navigate to Monitoring -> Status History:

OEM 12c AMS 12.1.0.4 – Navigation Target: Monitoring -> Status History

Change the Availability History view to All History (the related underlying event caused is displayed.)

OEM 12c AMS 12.1.0.4 – Target: Status History Details

If you click on the related Message (e.g. Target is down; 1 member is down: INSTANCE_hostname.auca.corp_oacore_JVM_…); you will then be shown the related Event page for that target:

OEM 12c AMS 12.1.0.4 – Target: Event Details

Click on the Related Events tab for this target, to confirm the service alert recorded:

OEM 12c AMS 12.1.0.4 – Target: Event Details -> Related Events Timeline

If this is a recurring issue, by sliding the timeline back and forth (and adjusting the period view to a larger sample) you can see if there are any associated time-related occurrences that can be used to identify root cause.

For the specific issue, login to the associated host, and view the output and error logs for the process itself to determine what triggered the alert (in this case, the JVM automatically restarted the OACore process that had run out of memory.)

R12 e-Business Suite and OEM Monitoring – Oracle Spins Freezes

Every so often, system load on an e-Business Suite instance ramps up and response time to users starts climbing, often resulting in user observed errors such as:

• FRM-92100 Your connect to the server has been interrupted
• FRM-92102 A network error has occurred

  

  That dreaded FRM-91201 / FRM-91200 error causing you to restart your session.

Or sometimes, the screen just freezes (aka spins, stops, is broken, stuck, motionless, looks like a screen saver,can’t do anything, won’t work, froze-up, etc.) and the person has to close their browser, or even shut-down their workstation and restart.

It’s simply not doing anything – Nothing to see here, just move your cursor around. And wait… and wait.

Old technology often barks with unrelated error messages to the actual cause.  If there’s a lot going on with concurrent requests, or interfaces, or analytic extracts running, the front-end response-time slows down, sometimes sufficiently to trigger these kinds of Form errors, even though technically there was no interruption to the network connectivity, either between the hosts, nor the workstation and the middle-tier application server.

However, on the database, the user-experience can be seen, although not necessarily in the place you might expect.  OEM  had introduced it’s Adaptive Metric Thresholds technology back in OEM 11g (in a slightly different place than in 12c (in Oracle Management Server/OMS 12.1.0.4.0).  In OEM 11g, they were a link under the AWR Baseline Reports page.

See the Baseline Metric Thresholds link at the bottom.

In OEM 12c, you’ll find them under

Targets -> Database -> Peformance -> Adaptive Thresholds -> Baseline Metric Thresholds -> Edit Thresholds:

Where those adaptive metric thresholds moved in 12c.

 

 

On this page and in the list of Baseline Metrics, when you click into them, you can access the trending statistics being gathered for each metric.  Many times this will provide direct insight into what a user experiences as the “the system is frozen” translates into “the back-end database response time is incredibly bad.”

See the spikes around 7AM and 11:30AM? Those are being associated with “System Froze” reports.

 

In the example here, the database experienced a dramatic slow-down in response almost 5 to 10 times slower than usual, which only lasted a few seconds. But that can be enough to show up in many users’ sessions who might have just kicked off a query, or were trying to save something.  Based upon the information gathered, we set the Warning and Critical thresholds to 1500ms and 2000ms respectively to start sending e-mail alert notifications upon breach of the levels. If the settings are left at “None”, no incident would be raised, and thus, no notification would be sent.

If you’re experiencing odd transient outages or sluggish behavior that defies the normal AWR and ADDM snapshot analysis, go take a look at what OEM has been gathering in the background over time and see if the statistics correlate to any of your issues.  There’s value in that data. Just mine it.

Run #em12c on #db12c? – Discussion from Oracle Open World (MOS Note: 1920632.1)

We also discussed this during the EM4APPS SIG Meeting
https://jhlui1.wordpress.com/2014/08/26/oow14-oracle-enterprise-management-for-applications-sig-mtg-928-mw3003-330p-415p/

Ok Folks, I’ve been here are Oracle Open World for a few days now.  In that time, I’ve had numerous conversations about running Oracle Enterprise Manager 12c on Oracle Database 12c.  I will be honest and say that I’ve enjoyed these conversations; however, after about the fourth time I decided I need to write a quick post on the explanation discussed in these conversations.  

Early this year (August) I wrote a post about the what came out of the OEM CAB in May 2014 and how to get OEM 12c to work on DB12c.  The concept of running OEM 12c on DB12c, pluggable or not, have many people excited and looking forward to configuring OEM to do that very configuration.  Heck, I’ve even installed it for a few customers in that configuration (non-PDB).  So I’m a bit sad in having to say this:  ORACLE DATABASE 12c SUPPORT FOR…

Enterprise Manager 12.1.0.4.0 – Post Upgrade Tasks

Must keep up with OEM 12c Grid Control updates…

Maaz Anjum's Blog

With the new release of Enterprise Manager, I upgraded my 12.1.0.3.0 installation successfully using the superb documentation here. It is however, important to note that the post-steps are also important. For example, upgrading (at the very least) the Management Agent on the OMS host, and de-installation of the old-OMS home. Gokhan Atil wrote a good post on the actual upgrade process which is available on his blog.

Management Agent Upgrade on the OMS Host:

The upgrade process for agents has not changed since EM’s previous 12c releases.

1. Navigate to the “Upgrade Agents” link under the Setup -> Manage Cloud Control menu.

2. Select the agent(s) for the OMS Hosts and click “OK”.

3. With the Agents selected, click on “Submit”. You have the option to override the “Privileged Credentials” to run the root.sh script.

4. The submitted job takes a few minutes before it completes (hopefully successfully!).

How to migrate EM12c R3 OMS and repository to a new host

Very useful, even if you’re moving parts of OEM 12c from one host to another, or modifying the filesystem mounts.

Pardy DBA

(EDIT 20130917: If you simply need to change the IP address of your OEM server, please review MOS note 1562029.1.  The procedure in that note may allow you to change your OEM server’s IP address without following the lengthy process I describe below.)

In order to save power in our data center, I need to migrate my EM12c R3 environment from the host where it currently runs to a new host.  I have a simple configuration, with a single OMS, no load balancer, and the repository database runs on the same host as EM12c R3 itself.  I also have BI Publisher installed and integrated with EM12c, and a few third party plugins as I’ve detailed elsewhere on this blog.  If you use an OS other than Linux x86-64 I suggest you research thoroughly as this procedure may or may not apply to your environment.  Further, if you have a multi-OMS…

Upgrade Oracle Enterprise Manager 12c (12.1.0.2) to 12.1.0.3

And we’re still awaiting 12c Database certification for the Repository.

In order to upgrade our OEM environment from 12.1.0.2 to 12.1.0.3 we need to download the latest version of OEM from either http://otn.oracle.com or from http://edelivery.oracle.com. Once we have the files needed to upgrade, we need to stage them in a location that is central.

Note: Most downloads on Linux will be placed in the /home/oracle/Downloads directory.

Once we are in the directory where the downloaded files are, we need to unzip these files.

#> unzip em12103_linux64_disk1.zip –d ./12.1.0.3

The zip command needs to be repeated for all of the files downloaded.

Next, we need to move into the directory where we unzipped everything and run the runInstaller.

#> cd ./12.1.0.3

#> ./runInstaller &

When the installer starts, we will be greeted with our standard Oracle Installation Wizard. To upgrade the OEM to 12.1.0.3, consists of nine steps. We will review these nine steps throughout this posting.

Step…
