64-bit Ubuntu installation of Oracle 11G

Brief process of installing Oracle 11G in 64-bit Ubuntu:

1: Set the environment

Sudo apt-get install rpm libaio1 ksh libtool libstdc ++ 5 build-essential

2:Set directory structure and symbolic link

1. Sudo ln-s/usr/bin/awk
2. Sudo ln-s/usr/bin/rpm
3. Sudo ln-s/usr/bin/basename
5. Sudo mkdir/etc/rc. d
6. Sudo ln-s/etc/rc0.d/etc/rc. d/rc0.d
7. ......
8. Sudo ln-s/etc/rc6.d/etc/rc. d/rc6.d
9. It can also be:
10. # For I in 0 1 2 3 4 5 6; do sudo ln-s/etc/rc $ I. d/etc/rc. d/rc $ I. d; done

If you do not connect to the following .. The file cannot be found... Error

1. Sudo ln-s/usr/lib/x86_64-linux-gnu/libc_nonshared.a/usr/lib64/
2. Sudo ln-s/usr/lib/x86_64-linux-gnu/libpthread_nonshared.a/usr/lib64/
3. Sudo ln-s/usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.5/libgcc_s.so/lib64/libgcc_s.so.1
4. Sudo ln-s/usr/lib/x86_64-linux-gnu/libstdc ++. so.6.0.14/lib64/libstdc ++. so.6
5. Sudo ln-s/usr/lib/x86_64-linux-gnu/libstdc ++. so.6.0.14/usr/lib64/libstdc ++. so.6

3: Set System Parameters
Modify /Etc/sysctl. conf

1. Fs. aio-max-nr=1048576
2. Fs. file-max=6815744
3. Kernel. shmall=2097152
4. Kernel. shmmax=536870912
5. Kernel. shmmni=4096
6. Kernel. sem=25032000 100 128
7. Net. ipv4.ip _ local_port_range=900065500
8. Net. core. rmem_default=262144
9. Net. core. rmem_max=4194304
10. Net. core. wmem_default=262144
11. Net. core. wmem_max=1048586

ModifyEtC/security/limits. conf

Modify "/etc/security/limits. conf" and add the following content. "jasmine" is the user name, which can be adjusted according to the actual situation.

1. Jasmine soft nproc2047
2. Jasmine hard nproc16384
3. Jasmine soft nofile1024
4. Jasmine hard nofile65536

Modify"/Etc/pam. d/login", Add the following content:

1. Session required/lib/security/pam_limits.so
2. Session required pam_limits.so

Then run the following command:

Sudo sysctl-p

Next, set the necessary environment variables, modify the ". profile" file in the user directory, and add the following content:

1. Export ORACLE_BASE ="/Home/oracle_11g"
2. Export ORACLE_HOME ="/Home/oracle_11g/server"
3. Export ORACLE_SID ="Orcl"
4. Export ORACLE_OWNER ="Orcl"
5. Export NLS_LANG ="Simplified chinese_china.al32utf8"

Now the system parameters and environment variables are set.

5: Install cd to the decompressed directory of oracle

./RunInstaller-jreloc/usr/lib/jvm/java_1.6.0_openjdk/jre

Jreloc specifies the jre instead of the built-in jdk.

Otherwise, garbled characters will appear.

So far OK.
