OEM13c Installation

This is article demonstrates the Installation of OEM 13c on OEL 7.2
--NOTE:  The installer requires about 10 GB of hard disk space in the temporary directory
Surmise:
Oracle database 12.1.0.2 must be Installed and configured before proceeding with the Installation
OEM13c repository  is only supported on 12.1.0.2 Database
 1.Create user and group
# groupadd omsdb  
# groupadd omsoper
# groupadd omsdba
# useradd -g omsdb -G omsdba,omsoper oem13c  
$ passwd oem13c

2.Create Directories and change permissions
# mkdir -p /u01/app/oem13c/product/12.1.0/db_1
# mkdir -p /u01/app/oem13c
# chown oem13c:omsdb -R /u01
# chmod 775 /u01/app/oem13c
 --OMS Home location
# mkdir -p /u01/app/oem13c/Middleware13c
# chmod -R 775 /u01/app/oem13c/Middleware13c/
# chown -R oem13c:omsdb /u01/app/oem13c/Middleware13c/

--AGENT dirctory location
# mkdir -p /u01/app/oem13c/Agent13c
# chmod -R 775 /u01/app/oem13c/Agent13c/
# chown oem13c:omsdb /u01/app/oem13c/Agent13c/

--OMS software library
# mkdir -p /u01/app/oem13c/oms_sw
# chmod -R 775 /u01/app/oem13c/oms_sw  
# chown -R oem13c:omsdb /u01/app/oem13c/oms_sw

 3.Verify the RPM packages
The following list of packages must be Installed on Linux-7 64-bit
yum install -y glibc-common glibc-devel glibc-profile glibc-headers  glibc-utils glibc
yum install -y make-3.82-21*
yum install -y binutils-2.23*
yum install -y gcc-4.8.2-16*
yum install -y libaio-0.3.109-12*
yum install -y glibc-common-2.17-55*
yum install -y libstdc++-4.8.2-16*
yum install -y sysstat-10.1.5-4*
yum install -y glibc-devel 2.17-55* (i686) (This is a 32-bit package)
yum install -y glibc-devel 2.17-55*(x86_64) (This is a 64-bit package)
yum install -y libXtst-1.2.2-2* (x86_64)

Check the “glibc” rpms:
# rpm -qa | grep glibc
# rpm -qa | grep glibc-common
# rpm -qa | grep glibc-devel
# rpm -qa | grep glibc-profile
# rpm -qa | grep glibc-headers
# rpm -qa | grep glibc-utils
# rpm -qa | grep glibc
  Or use this to do the above;
rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n' binutils \
gcc \
gcc-c++ \
glibc \
glibc-common \
glibc-devel \
glibc-headers \
ksh \
libaio \
libaio-devel \
libgcc \
libstdc++ \
libstdc++-devel \
libXext \
libXtst \
libX11 \
libXau \
libXi \
make \
sysstat \
unixODBC \
unixODBC-devel \
zlib-devel

4.Configure kernel parameters:
 Add the following entry  to file
# echo 11000 65500 > /proc/sys/net/ipv4/ip_local_port_range
# more /proc/sys/net/ipv4/ip_local_port_range
# vim /etc/sysctl.conf
net.ipv4.ip_local_port_range = 11000 65000
Make the changes permement by running the below
# sysctl -p
# /sbin/sysctl -a


 Add the HOSTNAME to /etc/hosts file

vi /etc/hosts
<IP-address>  <fully-qualified-machine-name>  <machine-name>
192.168.183.000  example.oem13c.com   example
 Validate the installer group
# more /etc/oraInst.loc

5. Download the software
Download all listed files from the url:
http://www.oracle.com/technetwork/oem/grid-control/downloads/oem-linux64-2823270.html

NOTE: DO NOT unzip the zipped files. Installer will unzip it as required

6.Database configuration BEFORE Installation
 1. show parameter optimizer     -- if  TRUE, set to FALSE
         alter system set optimizer_adaptive_features=false scope=both;
2. show parameter session_cached  --set to 350
         alter system set session_cached_cursors=350 scope=spfile;
3. show parameter shared_pool_size  --set to 1G
         alter system set shared_pool_size=1G scope=both;
4.select inst_id,name,open_mode,restricted from gv$pdbs;
--if MOUNTED THEN,
         alter pluggable database dlc13c open instances=all;
  7.Bounce the database to impact the changes on the system parameter values
shut immediate;
startup

8.Install the DB12c Repository

/runInstaller
9.START Installation of OEM 13c
Execute the binary file

 # chmod +x em13100_linux64.bin
