Installation process
Before installing pay attention, oracle for space systems is required before installation can be viewed at:
First, using the free -m to view the swap space, oracle XE requires swap space at least 1.2G, expanded method on my other blog post has been explained. Portal http://www.linuxidc.com/Linux/2012-08/66973.htm
Use df -h to see the size of tmpfs, oracle XE gives the minimum requirements in the init.ora file, the default is 1G.
Here we want tmpfs expanded to 2G:
1. Modify / etc / fstab file:
Find this line: tmpfs / dev / shm tmpfs defaults 0 0
Review of: tmpfs / dev / shm tmpfs defaults, size = 2048M 0 0
2. Reload tmpfs:
Use the command:
#umount /dev/shm; mount /dev/shm;
Then enter
df -h / dev / shm look at the output:
Filesystem Size Used Avail Use% Mounted on
tmpfs 2.0G 492M 1.6G 25% /dev/shm
Description reload success. [Linux] commune http://www.linuxidc.com
Second, this is done, we need to do some install some dependencies:
yum install libaio*
To install the package libaio
After unpacking the installation package,
unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip
Into the Disk1 folder
After extracting the installation package rpm
rpm -ivh oracle-xe-11.2.0-1.0.x86_64.rpm
Third, modify / etc / profile file, add the following:
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/xe; export ORACLE_HOME
ORACLE_SID=XE; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
TNS_ADMIN=$ORACLE_HOME/network/admin
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
After modification using the command # source / etc / profile to reload the changed file.
Enter echo $ ORACLE_BASE change was successful.
Fourth, modify / etc / hosts file, add the following:
127.0.0.10 hostname (hostname filled in accordance with the actual situation)
Fifth, run the following script with super user identity configuration:
# /etc/init.d/oracle-xe configure
Including http port, and if you run a tomcat on your server and not turn over the port configuration should replace the default port 8080 to avoid conflict.
In addition, the program will ask you to set a password for the default administrator account sys. Will then wait for some time, please be patient.
After installation, the system will automatically create a user called oracle, home dir location / u01 / app / oracle database is installed.
Sixth, the only switch user sqlplus oracle database link
sqlplus /nolog
Enter sqlplus console
SQL> connect as sysdba
Prompted for a user name and password: use sys / password login
Start and mount the database
SQL> startup mount
11g xe version has a built-in set a good database XE, and therefore not allowed to manually create the database, but you need to initialize the database structure
Run the two lines of code:
SQL> @?/rdbms/admin/catalog.sql
SQL> @?/rdbms/admin/catproc.sql
After waiting prompted complete, the next step.
If the database did not open during the operation appears you need to reboot and load the database. [Linux] commune http://www.linuxidc.com
Next, create a user, an initial database already exists in the users table should be, so the data can be directly inserted:
SQL> create user myaccount
2 identified by “mypassword”
3 default tablespace users;
Authorized Users:
SQL> grant dba to myaccount;
After the exit can then log in with the user.
Insert table test:
SQL> create table test_table (txt varchar2(100) not null);
SQL> insert into test_table values('Hello world !');
After successfully inserting data query
SQL> select * from test_table；
If the query is successful, then congratulations, you're done!
some problems:
If there is an error:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Usually because the database does not start, you need to enter the DBA database startup login
Before doing /u01/app/oracle/product/11.2.0/xe/dbs/ make sure the folder exists init <SID> .orc file exists
ORA-00845:MEMORY_TARGET not supported on this system
Please check your file init.orc value memory_target item is less than tmpfs, otherwise tmpfs expand capacity.
ORA-44410:XE edition single instance violation error
XE version can have only one instance, when I installed the program automatically generates the instance called XE and the path has been set up, as to how to add a new instance Supreme indicated.
or
To ensure that your environment variable is not '/' end while TNS_ADMIN variable has been set. As for why such a change .. hope to have an expert can tell me.
ORA-01261:Parameter db_recovery_file_dest destination string connot be translated
ORA-01262:Stat failed on a file destination directory
On this error, relatively silent, in init.orc in, db_recovery_file_dest destination that one of the initial value is "<ORACLE_BASE> / flash_recovery_area"
If you only modify the <ORACLE_BASE> you will get this error because only one file called fast_recovery_area under $ ORACLE_BASE, modify the back of the file name matches, the problem is solved.
