5. 5.Oem 12c Installation Procedure6. 6.Verification Checks7. 7.Starting and Stopping oem 12c Services

1. Software : The required software for the oem 12c cloud control are :

CentOS 6.5 (x86_64)  Download Oracle Database 12c (x86_64)  Download Enterprise Manager Cloud Control 12c (12.1.0.3) (x86_64) Download

2. OS Installation :We are using CentOS 6.5 for this installation. Please download the latest software and install OS. While installing the OS select the option to install database server, so the most of the required rpms will be installed by default.

3. Database Installation :Please follow my article Database 12c Installation on CentOS 6.5 for database installation. We need to have the database installed for oem 12c installation. It is called oracle management repository. Oracle database 12c is not yet certified with the oem 12c at the time i am writing this article. But i used database 12c as OMR for oem 12c installation.Please complete all the following pre-requisite on OMR[oracle@fsrsrv10 oem12c]$ sqlplus '/as sysdba'SQL*Plus: Release 12.1.0.1.0 Production on Mon Feb 24 03:04:33 2014Copyright (c) 1982, 2013, Oracle.  All rights reserved.

Please review the here to know the exact hardware requirements.

4.b Operating System Requirements :

Ensure that you install Enterprise Manger Cloud Control only on certified operating system as mentioned in the Enterprise Manager Certification Matrix.

4.c Package Requirements: Though we are using CentOS6.5, we will follow Linux 6.x requirement for the installation.For OMS : Platform 64-Bit Packages for 64-Bit Platform

Oracle Linux 6.x(Red Hat 6 Kernel and Unbreakable Enterprise Kernel (UEK))

make-3.81 binutils-2.20.51.0.2-5.11 gcc-4.4.4 libaio-0.3.107 glibc-common-2.12-1 libstdc++-4.4.4 libXtst-1.0.99.2-3.el6.x86_64.rpm sysstat-9.0.4 glibc-devel-2.12-1.7.el6.i686 (This is a 32-bit

package) glibc-devel-2.12-1.7.el6.x86_64 (This is a 64-bit

package) (Applicable only for Oracle Linux 6.2, which

includes RH6.2 and UEK 6.2) glibc-2.12-1.47.0.2

For Agent : 

Platform64-Bit Packages for 64-Bit Platform

Oracle Linux 6.x(Red Hat 6 Kernel and Unbreakable Enterprise Kernel (UEK))

make-3.81 binutils-2.20.51.0.2-5.11 gcc-4.4.4 libaio-0.3.107 glibc-common-2.12-1.7 libstdc++-4.4.4 sysstat-9.0.4

4.d Kernel Parameter RequirementsFor installing an OMS or a Management Agent on Unix operating systems (32-bit or 64-bit), set the kernel.shmmax parameter to a value 1 byte less than 4 GB or 4294967295.

4.e Library Requirements :Install glibc-2.5.12 package

4.f.Operating System Groups and Users Requirements:# /usr/sbin/groupadd oinstall# /usr/sbin/useradd -g oinstall oracle# passwd oracle

4.g Host Name and Static IP Address Requirements :Ensure that you check the network configuration to verify that the host on which you are installing resolves to a unique host name and a static IP address that is visible to other hosts in the network.You must use a static IP address. If you use a dynamic IP address, the installation might fail.Ensure that the host name specified in /etc/hosts file is unique, and that it maps to the correct IP address. Following is the recommended format of the /etc/hosts file:<ip address> <fully_qualified_host_name> <short_host_name>If the DNS server is configured, then it should resolve the host name for the OMS machine correctly. For example, all these command must return the same output:nslookup host1nslookup host1.foo.comnslookup 141.81.5.71

4.h.Temporary Directory Space Requirements :Ensure that you allocate 400 MB of space for a temporary directory where the executables can be copied.

4.i.Central Inventory Requirements :Ensure that you allocate 100 MB of space for the central inventory directory. Also ensure that the central inventory directory is not on a shared file system. If it is already on a shared file system, then switch over to a non-shared file system by following the instructions outlined in My Oracle Support note 1092645.1.To determine whether the Oracle Inventory group exists, enter the following command:     $ more /etc/oraInst.loc     If the oraInst.loc file exists, then the output from this command looks like:     inventory_loc=/u01/app/oracle/oraInventory     inst_group=oinstall

4.j.UMASK Value Requirements:Ensure that you set the default file mode creation mask (umask) to 022 in the shell startup file.

4.k.File Descriptor Requirements :If the current value is less than 4096, then as root user, update the /etc/security/limits.conf file as shown below:         <UID> soft nofile 4096         <UID> hard nofile 4096

4.l.Existing Database Version Requirements :Ensure that the database is patched with all the Patch Set Updates (PSU) or Critical Patch Updates (CPU) released for that release. Also ensure that you apply the patches.The database can also have the Automatic Memory Management (AMM) feature enabled.

4.m.Host File Requirements :

Ensure that the host name specified in the /etc/hosts file is unique, and ensure that it maps to the correct IP address of that host. Otherwise, the installation can fail on the product-specific prerequisite check page.The following is the recommended format of the /etc/hosts file:<ip> <fully_qualified_host_name> <short_host_name>

4.n.Port Requirements :Ensure that the ports you assign (within the given range) to the following components are free and available:

o Admin Server HTTP SSL Port = 7101 - 7200o Enterprise Manager Upload HTTP Port = 4889 - 4898o Enterprise Manager Upload HTTP SSL Port = 1159, 4899 - 4908o Enterprise Manager Central Console HTTP Port = 7788 - 7798o Enterprise Manager Central Console HTTP SSL Port = 7799 - 7809o Oracle Management Agent Port = 3872, 1830 - 1849o Node Manager = 7101 - 7200o Managed Server HTTP Port = 7201 - 7300o Managed Server HTTPS Port = 7301 - 7400
