This article will explain in detail the example analysis of graphical-silent installation in Oracle12c. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

1 installation planning

ORACLE is installed on the new disk, and the disk is mounted to U01 D01 and D02 is a symbolic connection, and the actual directory is under U01

Parameter value Oracle base/d01/app/oracleSoftware location/d01/app/oracle/product/12102/dbhome_1DATAFILEDESTINATION/d02/oradataRECOVERYAREADESTINATION/d02/fast_recovery_areaGlobal database namegorcl12cSIDorcl12c

2 Mount the disk

Fdisk-l # View the data disk fdisk-u / dev/vdb # Partition data disk # np1..wfdisk-lu / dev/vdb # View the new partition mkfs.ext4 / dev/vdb1cp / etc/fstab / etc/fstab.bakecho / dev/vdb1 / mnt ext4 defaults 00 > > / etc/fstabcat / etc/fstabmkdir / u01mount / dev/vdb1 / u01df-h

3 Mount SWAP

# ORACLE needs 1swap 4 of memory as swap to confirm the existence of swap. If so, swapoff / swapfileswapon-s # confirm hard disk space df-hal# create swap file 1024 * 16 = 16384 = 16GB (a little more than 16384 when actually created) dd if=/dev/zero of=/swapfile bs=16386 count=1024k# format mkswap / swapfilechmod 0600 / swapfile# activate swapswapon / swapfile# confirm the existence of swapswapon-s

4 system environment configuration

System configuration

# ORACLE needs 1swap 4 of memory as swap to confirm the existence of swap. If so, swapoff / swapfileswapon-s # confirm hard disk space df-hal# create swap file 1024 * 16 = 16384 = 16GB (a little more than 16384 when actually created) dd if=/dev/zero of=/swapfile bs=16386 count=1024k# format mkswap / swapfilechmod 0600 / swapfile# activate swapswapon / swapfile# confirm the existence of swapswapon-s

ORACLE user environment variables

Su-oraclevim ~ / .bash_profileORACLE_BASE=/d01/app/oracleORACLE_HOME=$ORACLE_BASE/product/12102/dbhome_1ORACLE_SID=orcl12cPATH=$PATH:$ORACLE_HOME/binexport ORACLE_BASE ORACLE_HOME ORACLE_SIDPATH ORACLE_SID

5 graphical interface configuration trample

Install graphical dependencies and desktop systems

$yum groupinstall "X Window System" # confirm the gnome name in available. Next, use $yum grouplist# to install gnome$ yum groupinstall "GNOME Desktop" # to enter the graphical interface $startx

Execute xdpyinfo under root to record connection characters

$xdpyinfo | grep namename of display:: 0

Execute under root (important). Default xwindow does not allow other users to connect.

$xhost +

Execute dpyinfo under oracle

$export DISPLAY=:0xdpyinfo...# displays normally.

This step is complete.

5 graphical installation

Database/runInstaller

6 create database graphically

Dbca

7 graphical configuration listener & tns to connect to the database

Refer to this article to configure
