Install Oracle under Linux, connect local pl/sql to Oracle import table under Linux, and create new user and password

linux Lower installation oracle, Local PL/SQL Connect Linux Under the oracle Import the table and create a new user and password

linux For the first time contact , install oracle And connecting to the import library has encountered a lot of trouble , Next, review the problems encountered and some commands .

1. First installation VMware Create a new virtual machine （ System version ：Centos6.5 X64） , The specific installation process will not be described in detail .

2. After building the virtual machine , Open the terminal .

Get into root jurisdiction ：su （ The password is the password established by installing the virtual machine ）

3. install oracle Dependency package （root）.

yum install compat-libcap1

 yum installcompat-libstdc++-33

  yum install libstdc++-devel

 yum installgcc-c++

  yum install ksh 

yum installlibaio-devel

4. Upgrade system jar package

 yum update

5. install oracle

  establish oracle Users and groups （root）

groupadd oinstall

groupadd dba

useradd -g oinstall -G dba oracle

passwd oracle

Create directory （root）

mkdir -p /oracle/

chown -R oracle:oinstall /oracle/

chmod -R 775 /oracle/

Modify kernel parameters （root）

vim /etc/sysctl.conf

open After this file Press i Edit status Copy the following into it

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 536870912

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

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 = 1048586

Press esc Key to exit Enter to execute ：wq Save and exit to the terminal interface

/sbin/sysctl -p Make parameters effective

Modify user restrictions （root）

vim /etc/security/limits.conf

Similarly, copy the following into it

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft stack 10240

oracle hard stack 10240

Press esc Key to exit Enter to execute ：wq Save and exit to the terminal interface

  Configure environment variables （oracle）

vim .bash_profile

open After this file Press i Edit status Copy the following into it

export ORACLE_BASE=/oracle/12c

export ORACLE_HOME=$ORACLE_BASE/db1

export ORACLE_SID=sgdb SID Is the database instance name The instance name of the database must be consistent with the name of the database ！！！！

export PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin

export EDITOR=/bin/vi

Press esc Key to exit Enter to execute ：wq Save and exit to the terminal interface

Make profile effective

[oracle@ localhost~]$ source .bash_profile

Connect FTP（ Configure the virtual machine network as a bridge ）

decompression ：[[email protected] Downloads]$ unziplinuxamd64_12102_database_1of2.zip After decompression, there is a database To open it Then double click. runlnstaller This file

Start installation oracle 了 The installation process is very simple. The next step is Finally, we need to execute two scripts, which is not written here

Next use linux Command configuration listening start-up oracle

1. obtain oracle Example

oracle Under authority ：echo $ORACLE_SID

To configure monitor

lsnrctl start

Start database

sqlplus / as sysdba

SQL< startup

because It's turned on here To close once shutdown In the after startup

It's over oracle in the future To start from local PL/SQL Connected to

First, configure monitoring locally to monitor linux This one on oracle

open oracle Self contained Net Manager

Configure listener

newly build Service naming

Connect After finishing test land system The password is the password of the virtual machine there system Yes, there is an ordinary administrator by default sys It's super administrator level Don't have different permissions Here we use system Just log in

test OK after Open the client to see if you can log in

Next, the local oracle Import to linux Under the oracle in

cmd Open command

set dbuser= user name

set dbpassword= password

set dbserver=10.1.1.6:1521/ Database instance name （IP It's database ）

set filename=F:\dbback.dmp

utilize exp command

exp user name / password @10.1.1.6:1521/ Instance name file=F:\dbback.dmp enter

export Check after F Discoid dmp Whether the format file exists Then import

You can import through the interface plsql

Can also pass imp command

Empathy imp system/ password @ Database instance name file= The exported file name full=y Import all

Import Log in after success see table Whether the table you imported exists in

Then create your own user name and password , Don't use default system This

First

1. Create a temporary table space This step can be ignored, not necessary

2. Create tablespace

Check the file location before creating

SQL<select name from $datafile;

CREATE TABLESPACE Table space name datafile '/oracle/12c/oradata/database/test.dbf' Here you can customize the file location

3. Create users and passwords

CREATE USER user name IDENTIFIED BY password DEFAULT TABLESPACE Table space name

4. To give permission

grant connect,resource,dba to user name

Then open the PL/SQL Just log in to the user name you just created, and then create a table

Well, that's it .

If you have any questions above, please correct them. Thank you ！
