OEM Cloud Control 13c Installation Step by Step
Oracle Enterprise Manager
Cloud Control 13c Release 3 (13.3.0.0) Installation on Red Hat Enterprise Linux
Server release 7.5
PURPOSE: All documents are provided on this Blog just for educational purposes only. Please make sure that you run it in your test environment before to move on to production environment.
Those are basic steps for the OS level. You may need or not. It depends on your environment.
You do not
need to setup environment for Oracle_home and ASM and OEM. When the
Installation completed then you can set it up.
If you see yum issue, then you can try to fix issue as follow:
#
subscription-manager refresh
# yum
repolist all
# yum
update -y
Following packages are necessary for the cloud
control and Oracle Installation.
yum install -y bc binutils compat-libcap1
compat-libstdc++-33 compat-libstdc++-33.i686 elfutils-libelf.i686
elfutils-libelf elfutils-libelf-devel.i686 elfutils-libelf-devel

Database Installation (Software-Only)
I am going
to use 18c Software, but the Installation will work as well as on 12c.
Allocating
200 GB Raw device for ASM
You can
check via fdisk -l
....
....
Disk
/dev/sdc: 214.7 GB, 214748364800 bytes, 419430400 sectors
....
....
Create a rules file for asm and save it.
vi
/etc/udev/rules.d/99-oracle-asmdevices.rules
KERNEL=="sdc",OWNER:="oracle",GROUP:="dba",MODE:="660"
Execute the
following command, which will reload the rule.
udevadm control --reload-rules &&
udevadm trigger
Now the device is owned by oracle:dba
# ll
/dev/sdc

Stop the Firewall and disable
systemctl stop firewalld.service
systemctl disable firewalld.service
iptables -L
Download Oracle Database 18c Grid
Infrastructure (18.3) for Linux x86-64 and ASM
LINUX.X64_180000_grid_home.zip
Copy the above file in the grid home and unzip
the file:
cd /apps/oracle/app/home/product/18.0.0/grid_18
$ unzip
LINUX.X64_180000_grid_home.zip
Patching existing software with patch 28096386 (18.3) which will perform patching prior actual installation
DISPLAY=xxx.xx.xx.xx:0.0;
export DISPLAY
This
command will also install grid + patch.
$ ./gridSetup.sh -applyRU
/download/28096386
Do not forget to install cvuqdisk-1.0.10-1.rpm
As root:
cd /apps/oracle/app/home/product/18.0.0/grid/cv/rpm
rpm -Uvh cvuqdisk-1.0.10-1.rpm
ps -fu
oracle
Now you can install just Oracle 18c software.
Oracle 18c software.
cd
$ORACLE_HOME
unzip
LINUX.X64_180000_db_home.zip
I am using MobaXterm for xterminal.
DISPLAY=xxx.xx.xxx.xxx:0.0;
export DISPLAY
./runInstaller
NOTE: The steps are straightforward. I am not going to add the screenshot.
As root user execute the script.
# /apps/oracle/app/oraInventory/orainstRoot.sh

Changing group name of /apps/oracle/app/oraInventory
to dba.
The
execution of the script is complete.
# /apps/oracle/app/home/product/18.0.0/dbhome_18/root.sh
Performing
root user operation.
The
following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /apps/oracle/app/home/product/18.0.0/dbhome_18
Enter the
