rhel7.2 Installing Oracle 12C

os:rhel7.2

ORACLE 12C

Step1: Installing the required RPM packages

Yum install binutils libX11 compat-libcap1 libxau compat-libstdc++-33 libaio gcc libaio-devel gcc-c++ libdmx glibc-devel g libc ksh make LIBGCC sysstat libstdc++ xorg-x11-utils libstdc++-devel xorg-x11-xauth libxext libxv libxtst libXi libxcb li BXt libxmu libxxf86misc libxxf86dga libxxf86vm nfs-utils smartmontools

Step2: Modifying kernel parameters

Vim/etc/sysctl.d/98-oracle-kernel.conf

vm.swappiness = 1

Vm.dirty_background_ratio = 3

Vm.dirty_ratio = 80

Vm.dirty_expire_centisecs = 500

Vm.dirty_writeback_centisecs = 100

Kernel.sem = 250 32000 100 128

FS.AIO-MAX-NR = 1048576

Net.ipv4.ip_local_port_range = 9000 65500

Net.core.rmem_default = 262144

Net.core.rmem_max = 4194304

Net.core.wmem_default = 262144

Net.core.wmem_max = 1048576

KERNEL.MSGMNB = 65536

Kernel.msgmax = 65536

Kernel.shmmax = 8589934590 ==8g, larger than SGA

Kernel.shmall = 2147483648 ==8g

Kernel.shmmni = 4096

Sysctl-p/etc/sysctl.d/98-oracle-kernel.conf

Step3: Set User Limits

Vim/etc/security/limits.d/99-grid-oracle-limits.conf

Oracle Soft Nproc 2047

Oracle Hard Nproc 16384

Oracle Soft Nofile 1024

Oracle Hard Nofile 65536

Oracle Soft Stack 10240

Oracle Hard Stack 32768

STEP4: Adding users

Groupadd--gid 54321 Oinstall

Groupadd--gid 54322 dba

Groupadd--gid 54326 Oper

Groupadd--gid 54327 BACKUPDBA

Groupadd--gid 54328 DGDBA

Groupadd--gid 54329 KMDBA

Useradd--uid 54321--gid oinstall--groups dba,oper,backupdba,dgdba,kmdba Oracle

echo "Oracle" |PASSWD--stdin Oracle

STEP5: Setting up a directory

Mkdir-p/u01/app/12.2.0/grid

Chown-r oracle.oinstall/u01

Chmod-r 755/u01

STEP6: Setting Environment variables

Su-oracle

Vim. Bash_profile

Export Oracle_base=/u01/app/oracle

Export Oracle_home= $ORACLE _base/product/12.1.0/db_1

Export ORACLE_SID=ORCL

Export path= $ORACLE _home/bin: $PATH;

STEP7: Start Installation

Su-root

Xhost +

DISPLAY not set. Please set the DISPLAY and try again.

Depending on the Unix Shell, you can use one of the following commands as examples to set the DISPLAY environment variable :

-For CSH:% setenv DISPLAY 192.168.1.128:0.0

-For SH, ksh and bash: $ display=192.168.1.128:0.0; Export DISPLAY

Use the following command to see what Shell is being used:

Echo $SHELL

Use the following command to view the current DISPLAY environment variable setting:

Echo $DISPLAY

-Make sure. Client users is authorized to connect to the X Server.

To enable clients users to access the X Server, open a xterm, dtterm or XConsole as the user that started the session and Type the following command:

% xhost +

To test the DISPLAY environment variable are set correctly, run a X11 based program that comes with the native Operati ng system such as ' xclock ':

% <full path to xclock. See below>

If you is not a able to run Xclock successfully, please refer to your pc-x Server or OS vendor for further assistance.

Typical path for xclock:/usr/x11r6/bin/xclock

After trying to set up a number of $display, not all, as follows

Display=192.168.107.155:0.0;export $DISPLAY

Display=192.168.107.155:1.0;export $DISPLAY

Display=192.168.107.155:0.1export $DISPLAY

Display=:0;export $DISPLAY

Display=:1;export $DISPLAY

Then I executed xclock in a window of root, found no clock, and then installed Xorg-x11-apps (yum install Xorg-x11-apps), using root xclock to see the clock.

After that, Su-oracle still can't see the clock.

After the echo to the root window $DISPLAY found to be: 0, so I also set in the Oracle window

Display=:0;export $DISPLAY

After that, the normal graphical installation is possible.

Installation process:

Fix it here.

Ignoring the swap alarm, I'm only splitting the swap by 1G.

STEP8:DBCA Building Library

Here you can choose a typical configuration, or you can choose a custom configuration, I chose the custom (Advanced configuration)

Create Listner, called Listner1

To the SGA Sub 6G,PGA 500M, this is the test library, I alone with
