Deploying an Agent from a Windows 12.1.0.4 OMS fails

I’ve just setup a new Oracle Enterprise Manager Cloud Control 12.1.0.4 on Windows Server 2008 R2 for Customer. It’s a small one system setup, which will be used to monitor a few Oracle Databases on Windows and Linux. After the successful setup I’ve tried to deploy agents from the console, using the AgentPull. I have already performed this several times successfully. But somehow it does not work with 12.1.0.4. It fails while creating the plugin archive…

Creation of the plugin archive “e:/oracle/product/gc_inst/em/EMGC_OMS1/sysman/agentpush//plugins/windows_x64/12.1.0.4.0_PluginsOneoffs_233.zip” failed. Check the log file e:/oracle/product/gc_inst/em/EMGC_OMS1/sysman/agentpush/logs/EMAgentPushLogger.log for more details

Solution

It seems, that 12.1.0.4 on windows does have issues creating the agent image when OMS_HOME is on a different drive than SCRATCHPATH.
In my installation the OMS_HOME is on drive D: whereas SCRATCHPATH is on drive C:. The solution is straight forward. I’ve just have to reconfigure the SCRATCHPATH in ssPaths_msplats.properties.

cd $OMS_HOME\oui\prov\resources\
cp ssPaths_msplats.properties ssPaths_msplats.properties.bck

vi ssPaths_msplats.properties

SCRATCHPATH=C:/tmpada

SCRATCHPATH=D:/tmpada

As soon as this has change you may re-deploy the agent from the console.

Requirements

The requirements are still the same as for 12c release 1 and release 2. The following excerpt has been taken from Oracle® Enterprise Manager Cloud Control Basic Installation Guide.

  • OS requirements: Oracle Linux 6, Oracle Linux 5.x, Red Hat Enterprise Linux 5.x, SUSE Linux Enterprise 10, SUSE Linux Enterprise 11, Asianux Server 3

Howto change SYSMAN password in 12C Cloud Control

I was on leave for the past few weeks. After digging through tons of e-mails I finally found time to look into EM 12 Cloud Control. Unfortunately, I’ve forgotten my SYSMAN password and the EM 12c test installation is no longer running. As you say: “Holidays where one forgets everything, must be good holidays.”

So far so good, but what about my problems. Lets start with EM 12c which is not running. I started the VM from scratch. After login in over ssh I’ve realized that the EM 12c infrastructure is running. To my surprise the installer configured the start / stop script gcstartup in /etc/init.d and the corresponding rc directories. The script exists already since EM 10g but I’ve never used it. Unfortunately nobody created the start / stop script for the database and the listener. As soon as starting them manually I’ve just have to bounce the EM 12c to be up and ready again. It is not enough to just start the database. Restarting or starting the OMS is also necessary due to the fact that the OMS is not started when the database is not available during the startup of EM 12c. Oracle described this in a MOS Note EM Cloud Control 12c OMS not able to start after server reboot [1367876.1]

My second problem is quite a common issue. You’ll find some notes on how to change the SYSMAN password for EM 10/11g, DB Console and new as well for EM 12c. Basically it is done in a similar way as in EM 11g. It is just a little easier because it is not necessary to do the change in two steps. You may use use emctl to change the SYSMAN password for the OMS infrastructure and well the database account. That’s also what you can specify the SYS password when using emctl.

  1. Stop all OMS: emctl stop oms
  2. Change the password: emctl config oms -change_repos_pwd -use_sys_pwd -sys_pwd sys user password -new_pwd new sysman password
  3. Stop the Admin server and restart all OMS: emctl stop oms -all; emctl start oms

An example output: 

emctl config oms -change_repos_pwd -use_sys_pwd -sys_pwd manager -new_pwd tiger

Howto install Oracle Enterprise Manager Cloud Control 12c Release 1

Requirements

First of all lets start with the requirements. Which OS and database is supported for the OMS, Agent and repository database? The documentation is a bit thin on this topic (Oracle® Enterprise Manager Cloud Control Release Notes Prerequisites) and refers to the Metalink Certification Matrix.

Supported OS for the OMS and Agent are currently only the following Linux x86-64:

  • Oracle Linux 5 Update 2+
  • Asianux 3
  • Red Hat Enterprise Linux 5 Update Level 2+
  • SLES 11

Details about the required package is available in the Oracle® Enterprise Manager Cloud Control Basic Installation Guide Package Requirements for Oracle Management Service.

The OMS repository is currently certified with the following database release:

  • Oracle 11.2.0.3.0 (somehow not yet or not anymore in the MOS certification matrix)
  • Oracle 11.2.0.2.0
  • Oracle 11.2.0.1.0
  • Oracle 11.1.0.7.0
  • Oracle 10.2.0.5.0

The Prerequisites of chapter 6 Installing Enterprise Manager System in Oracle® Enterprise Manager Cloud Control Basic Installation Guide lists a few one-off Patch when using a 11.2.0.1.0 database. In general I would any way recommend to use the latest release as well the latest PSU.

The minimal hardware requirements for the OMS is a bit more than earlier releases. The table is just copy from Oracle® Enterprise Manager Cloud Control Basic Installation Guide Meeting Hardware Requirements.

Small Medium Large
1 OMS, < =1000 targets, <100 agents 2 OMSes for < =10,000 targets and <1000 agents >2 OMSes, >=10,000 targets, >=1000 agents
CPU Cores/Host 2 4 8
RAM 4 GB 6 DB 8 GB
RAM with ADP, JVMD 6 GB 10 DB 14 GB
Oracle WebLogic Server JVM Heap Size 512 MB 1 DB 2 GB
Hard Disk Space 7 GB 7 DB 7 GB
Hard Disk Space with ADP, JVMD 10 GB 12 DB 14 GB

Test Environment

To test Enterprise Manager Cloud Control I decide to use as usual a VM on my notebook. This means that the repository DB, OMS and Agent to run in a single VM. Based on the requirements above I end up with the following setup.

Hardware/VM Configuration:

  • VMWare Fusion 4.0.2
  • 2 Core’s
  • 4 GB Ram
  • 4 VM Disk not pre-allocated (20GB root, 4GB swap, 2*20GB data and software
  • 1 Network Interface

OS Configuration:

  • Oracle Enterprise Linux x86-64bit 5 update 6
  • OS has been setup through kickstart with these additional packages. Full KS file is attached to the blog post
  • oracle-validated, kernel-headers, sysstat, setarch, rng-utils
  • Kernel parameter should be set by oracle-validated

Repository Database:

  • Oracle Enterprise Edition 11.2.0.3.0
  • Database Components JVM, XDB, Multimedia (could probably be stripped down)
  • Init.ora parameter dedicated to EM12C:
    • SGA_TARGET=2G
    • SHARED_POOL_SIZE=600M
    • PGA_AGGREGATE_TARGET=1G
    • PROCESSES=300
    • JOB_QUEUE_PROCESSES=20
    • SESSION_CACHED_CURSORS=300
    • MEMORY_TARGET => should not be used

Software

next to the operating system and database software you need only the two zip files (em12_linux64_disk1of2.zip, em12_linux64_disk2of2.zip) from OTN to install EM12C. It is no longer necessary to search for Patch’s, WLS or JDK’s and download them. The software package for EM12C include everything you need to install the OMS and Agents.

Installation

Now that the test environment and repository database is ready lets start the installation. According to the presentation Oracle Enterprise Manager 12.1 – Cloud Control Upgrade it should be much easier. However the setup will start as usual with the RunInstaller.

./runInstaller

The installer starts as usual with the welcome screen and the optional question of the an e-Mail account to get informed about updates and security issues. The color layout of the dialog boxes has changed slightly. Otherwise, business as usual
EM12c Dialog 1

On the second screen you may specify your MOS credentials to instantly download the latest updates. Just hope that there are not yet any 😉
EM12c Dialog 2

In the third step the installer check’s the system prerequisites. Failed step’s can be fixed and be retested or just ignored. Because I’ve installed the RPM oracle_validated all dependent packages are installed some kernel parameters are adjusted.
EM12c Dialog 3

On the third step you have to specify the installation type and location of the middleware. For my test case I just select simple installation and /u00/app/oracle/product/middleware as the middlware home
EM12c Dialog 4

The WLS Administrator credentials and the repository connection details have to be specified on the fifth screen.
EM12c Dialog 5

Just right after you press next the installer connect’s to the repository database and check’s if the database can be used as EM repository. First it checks if there is a default CBO stats gathering job. You may let the installer fix this by pressing yes.
EM12c Dialog 5a

Second it checks the database configuration parameter and space setting. The information provided here do not have to be fixed immediately. The adjustments can be done after the installation of EM. In my first installation I’ve had a few failing prerequisites more. Since I set the init.ora parameter according the section above only three are left. I’ll fix all three of them after the installation. OK, redo size of 300M on my test VM I will just ignore.
EM12c Dialog 5b

Screen six sum up all information provide so fare before the installation starts.
EM12c Dialog 7

The installation it self is presented in a nice new way. For each installation step there is a direct link to its log file.
EM12c Dialog 7a

If something fail, you can immediately verify the issue by clicking the link to the log. As soon you fixed the issue, you can rerun the failed step. In my case the VM run out of memory (Physical and Swap) and the OMS could not be started.
EM12c Dialog 7b

I’ve extend the swap space up to 4G and restarted the step.
EM12c Dialog 7c

Done…. The last screen of the installation display the link information for the EM Cloud Control Console and the Administration URL. All information is also available in the file setupinfo.txt.
EM12c Dialog 8

First impression

Connecting the first time with EM console allows you to select you preferred EM Home page based on you role. E.g there is one for EM Administrators which looks quite similar to the old home page. Other home pages a displaying immediately information important to a Database Administration, WLS Administrator, Support personnel or other.

As a first step I’ve added a DB Target to get more information displayed in my EM. I’ve just run a bit out of time, thats why I haven’t yet more screen shots to display. I’ll provide a few more later.

Round up

All together the installation of EM Cloud Control 12c is much easier than installing one of the earlier releases. Oracle finally packed all together in one software package and one installer. I do not have to care anymore about the right JDK or WLS version. They are just installed. The side effect on this is that also on the OS everything is installed on the same place. Where at 10g and 11g separate directories has been used for OMS and agent, they are now below the middleware directory. Which is not really an issue, you only need to adjust any scripts and environment variables.

Apart from the simple installation procedure, I also like the small improvements while checking the prerequisites. Things which have to be fixed can be fixed immediately. Others, which are required to run the OMS, but not to finish the installation, can be fixed afterwards.

The only drawback I see after my first short tests are the quite high CPU and memory needs. For a regular system, this is not really a problem. But for a road warrior where all testing is done on a notebook, a VM with a 4-6GB is quite an issue.
