Service Test failed on OEM12c due to JAVA7 upgrade

 

Recently I faced issue with my Service Tests created for ENOVIA application. Java was upgraded from Java 1.6_24 to Java1.7_79 on our Enovia Servers.

Everytime when I perform verify Service test I get “Remote host closed connection during handshake– https://chapxxx.oii.xxx.com:9010/enovia/emxLogin.jsp” Error message .

Since then all the Service Test for ENOVIA were showing down but on the contrary all other Service tests for other applications are working fine.

Now OEM12c supports only till Java 6 Update 95, and this java upgrade was causing the Service Test to failed at every run. So the only workaround I was thinking was either upgrade my OEM to 13c which support JAVA or if possible lower the version of JAVA on ENOVIA servers.

What I did to resolve this Issue.

Issue:

Service test failed: “Remote host closed connection during handshake– https://chapxxx.oii.xxx.com:9010/enovia/emxLogin.jsp” Error message .

Cause:

Java upgrade from Java 1.6_24 to Java1.7_79

Resolution:

Steps for Implementing TLSv1 with OEM 12.1.0.4 to Fix Poodle Attack (Doc ID 2059368.1)

Steps to be followed:

  1. Applied recommended patches and update java on OMS to jdk 6 update 95.
  2. Update Java on the agent {Beacon Agent} host to jdk 6 update 95.
    1. [NOTE: This step is required only when the agents are monitoring TLSv1 enabled 12.1.3 middleware targets]
    2. Download the Patch 20418674 from Doc ID 1439822.1 All Java SE Downloads on MOS
    3. Follow the instructions as per the example given in Doc ID 1944044.1 EM12c: How to Use / Update JDK 1.6u Version on Agent.
  3. Configure the Agent to switch to TLSv1 as per the following document under the section “Oracle Management Agent”.
    1. Doc ID 1938799.1 CVE-2014-3566 Instructions to Mitigate the SSL v3.0 Vulnerability (aka “Poodle Attack”) in Oracle Enterprise Manager Grid / Cloud Control

Once you have performed all the steps make you your result look like this.

PRVF-0002 : Could not retrieve local nodename

I faced this error recently when I was building up my VM to install and configure OEM12cR5 on it. So before I can start with OEM setup I have to install Oracle Database for OMR. While I was performing Oracle 12c Release 1 database installation on my Virtual Machine on Virtual Box having Oracle Enterprise Linux 6 on it I came across this error.

[oracle@localhost database]$ ./runInstaller

Starting Oracle Universal Installer…

 

Checking Temp space: must be greater than 500 MB.   Actual 45136 MB    Passed

To check if my hostname is setup properly, I thought of looking into my hosts file and there it was.  The problem was that the hostname was missing in the hosts” file:

[oracle@localhost database]$ hostname

localhost.em13c

[oracle@localhost database]$ cat /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

 

Using the editor I put the entry of my hostname in “hosts” file under “/etc/hosts”.  Make sure you have proper permissions while making that change. Login with root user and do the required editing and save the file.

So after making the changed my “hosts” file looked like this.

 

[oracle@localhost database]$ cat /etc/hosts

127.0.0.1   localhost localhost.em13c

::1         localhost localhost.em13c

 

After making this change, I ran the installer again and this time the setup ran successfully without any error messages.

 

Also the other option can be before running the setup you can set the value of Environment Variable “ORACLE_HOSTNAME” to your hostname and then run the setup.

 

[oracle@localhost database]$ ORACLE_HOSTNAME=localhost.em13c

[oracle@localhost database]$ export ORACLE_HOSTNAME

12c Agents compatibility with OMS 13c…

Last time when I performed upgrade from 11g Grid Control to 12c Cloud Control, I had to replace all existing 11g Oracle Agents to Agent 12c. Oracle stated that 11g Oracle Agents are not compatible with OEM 12c, so it left me with no other option than to install Oracle Agent 12c on all monitoring hosts.

Even though multiple Agent installation on different hosts is available in 12c cloud Control but for one time when you have to do install and configure Agent 12c on more than 150 hosts, you really do not want to do that and could there have been shortcut it could have ease your life.

The same question came to my mind again, do I have to replace all my existing 12c Agents if I upgrade to this new release.  The answer is “NO” I do not have to replace my old Oracle Agent 12c.

Thanks to Oracle you do not have to do it but only if you have Oracle Management Agent 12c Release 3 or higher installed on your hosts.

YES, that’s true. Oracle Agent 12c is compatible with new release of Oracle Management Service 13c.

Mentioned below is the Compatibility table across OMS13c and Agent 12c.

Releases Oracle Management Agent 12c Release 3 (12.1.0.3) Oracle Management Agent 12c Release 4 (12.1.0.4) Oracle Management Agent 12c Release 5 (12.1.0.5) Oracle Management Agent 13c
Oracle Management Service 13c Yes Yes Yes Yes

There are some important points which you have to keep in mind before you begin Installing OEM 13c.

  • Ensure that you have the latest Enterprise Manager Cloud Control software. {13c}
    • You can refer to the Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide.” for more information.
  • Oracle Management Service 13c can communicate only with the above listed versions of Management Agents.
  • Another important point to remember is while you download and run the OEM 13c software making sure there are no white spaces in the name of the directory.
    • Example: do not download and run the software from a directory titled “EM Software” because there is a white space between the two words of the directory name.
  • Through installation wizard, installation of OEM 13c Cloud Control can be done only on a single host, that is, locally on the server from where the wizard is invoked. Installation cannot be done on multiple or remote hosts.
  • Do not set the ORACLE_HOME and ORACLE_SID environment variables, also you must ensure that the Oracle directories do NOT appear in the PATH.
  • OEM13c onwards preinstalled JDK or Oracle WebLogic Server is no more supported.
  • Java Development Kit (JDK) 1.7.0_80 and Oracle WebLogic Server 12c Release 1 (12.1.3.0) are installed as the part of EM13c Cloud Control.
  • Dedicated Weblogic Server 12c.
    • You must ensure that the Oracle WebLogic Server 12c Release 1 (12.1.3.0) installed by the Enterprise Manager Cloud Control Installation Wizard is dedicated for Enterprise Manager Cloud Control.
    • You must not have any other Oracle Fusion Middleware product installed in that Middleware home.
  • OEM 13c Cloud Control cannot coexist with any Oracle Fusion Middleware product in the same Middleware home because the ORACLE_COMMON property is used by both the products.
  • As a prerequisite, you must have an existing Oracle Database {can also have the Automatic Memory Management (AMM) feature enabled} to configure the Management Repository.
  • Manual Startup required for OMS and OMA.
    • If you install the OMS and the Oracle Database, which houses the Management Repository, on the same host, then when you reboot the host, the OMS and the Management Agent installed with it will not automatically start up. You will have to manually start them.

I have listed few of the important ones, you can find detailed information in Oracle Documentation.

Hope this will help you setting up your new environment.

You can reach out to me on my personal email id: sharma.deepak345@gmail.com

I hope this will help you do design your server before you install Oracle Enterprise Manager 13c on that. Make sure you do meet minimum requirements as listed above in the three table, failing in same will result in Poor Performance and if unlucky your system might also get crash. It happened with me very first time. 😉

Play Safe…

OEM 13c Step by Step Installation on Windows

In this blog I have explained the step by step installation of Oracle Enterprise Manager 13c on Windows server.

 

Make sure you have sufficient resources on your laptop or server since OEM13c is really very heavy and might slow down performance of your machine if it does not get sufficient food {resources }.

Since I have done installation on my personal laptop so I have mentioned the resource requirement accordingly. So make sure your machine has below listed resources available.

 Minimum CPU, RAM, Heap Size, and Hard Disk Space Requirements Per OMS for Simple Installation

   Simple Installation
Deployment Size Evaluation or Simple
Configuration 1 OMS, <100 Targets, <10 Agents, <3 Concurrent User Sessions
CPU Cores/Host

(Can be shared with other processes)

2
RAM11The physical memory mentioned here includes .5 GB of RAM required for Oracle BI Publisher. At the time of installation, if you choose not to configure Oracle BI Publisher, then the actual physical memory required can be .5 GB less than what is mentioned here.

(With Oracle BI Publisher and JVMD Engine)

10 GB
Hard Disk Space

(With Oracle Software Library, Oracle BI Publisher, and JVMD Engine)

24 GB
Temporary Directory Hard Disk Space 10 GB
Oracle WebLogic Server JVM Heap Size 1 GB

I am assuming you already have a database created for your OEM. In my environment I have 12C database created.

Step 1: Download the software. {there are 5 files}

http://www.oracle.com/technetwork/oem/grid-control/downloads/oem-windows-2823282.html

Step 2: Run the installer

image1

It will run for sometime and you can monitor the progress.

image2

Once the Installer is finished, it run the prerequisite system compatibility test to start the setup.

image3

Step 3: Enter your MOS account details (optional), if you want to receive security updates from Oracle.

image4

Just a warning will be displayed if you skip your “Support Details” part, you have to confirm that you do not wish to receive updates.

image5

Step 4: Software update search. It is recommended to run this step to ensure your environment is ready for this installation.

image6

If your machine is having all the updated required softwares it will prompt “No updates found”

image7

Step 5: Prerequisite Check. It will run a check to ensure you have sufficient resources available.

{Like in my case I got warning for in-sufficient RAM minimum required was 10 Gb and I had 8Gb of RAM, still I decided to continue with Installation. I was crazy to test this new release and lazy enough to increase my machine’s RAM to 10Gb.}

image8

Click NEXT to continue with Installation.

image9

Step 6: Installation Type. {Simple or Advanced}

If you are already familiar with previous releases and are EM DBA you can go for “Advanced” option.

image10

Step 7: Setting up Installation directories. Here you have configure you Middleware Home, Agent Base Directory and Hostname.

image11

Step 8: Set Administrator Password and put your database connection details.

[Informational message will pop-up with recommendation to setup AL32UTF8 character set for EM Repository database.]

image12

Click OK, it will execute some prerequisite checks.

image13

In next few steps you will be prompted for mismatch of you database settings if they already do not match with the recommended setting for OEM13c installation.

Prompted to check “optimizer_adaptive_features” parameter

image14

Prompted to check “parallel max and min servers” parameter

image15

Prompted to check “shared_pool_size” & “session_cached_cursors” parameter

image16

Step 9 :  Configure Software Library  and Enable BI Publisher.

OEM13c gives you option to configure and enable “BI Publisher” during Installation itself.

image17

Step 10: Review all details entered in all previous steps.

image18
