The Oracle 11g database provides a Linux x86 version, but the supported Linux versions are only red Hat,novell and Solaris, Debian and Ubuntu are not supported, so installing under Ubuntu is relatively cumbersome, Please follow the method step-by-step installation, do not be impatient, every step must be taken seriously (I began to pretend to be a little anxious, with their own method to simplify a few steps, the results ....) Installation failed-_-b). My system: Ubuntu 8.04 Desktop (32-bit) Memory: 896M (originally 1G, divided 128M to video card) This article is "Installing Oracle 11g on Ubuntu 8.04 LTS (Hardy Heron)" article translation and Annotation, is written by a foreign ox, the original: Http:// If you do not want to read the E-text can see my translation: Black text is the original translation, the red Word is my annotation, blue for the terminal input and output (reprinted annotated Source:) A total of 9 steps: Step 1 Download and install the Ubuntu 8.04 Hardy Heron (x86-32 bit) version. Slightly. Step 2 Downloads Oracle 11g:download Oracle 11g for Linux (x86, 32-bit). Now do not rush to extract, a while I will tell you where the decompression. Step 3 modifies the default settings for x server, the system-> Administration-> Login window for the Point menu, the Security tab, and cancel the Deny TCP connections to the Xserver (Deny TCP connection to x server), reboot Xserver (or reboot the system). Then on the terminal input: user@hardy:~$ xhost + being added to access control List Step 4 opens the terminal and converts it to Superuser: (Note that this is in sudo su-and It's not sudo-s for a reason: sudo su-converts a user to Superuser and a new session (an empty session) instead of the current session as Sudo-sDeliver a new superuser, reducing the potential impact and harm of environment variables. user@hardy:~$ sudo su-[sudo] password for user:root@hardy:~# apt-get update ... root@hardy:~# apt-get ... root@hardy:~# Reboot Step 5 installs some of the necessary tools with apt: user@hardy:~$ sudo su-[sudo] password for user:root@hardy:~# apt-get Build-essential libaio1 gawk ksh libmotif3 alien Libtool ... lsb-rpm step 6 after loading those tools, all we need to do is modify some of the Ubuntu/b In/sh default connection, do not skip this step, otherwise there will be many errors installed. root@hardy:~# cd/bin root@hardy:/bin# ls-l/bin/sh lrwxrwxrwx 1 root root 4 2008-04-28 19:59/bin/sh-> Dash Root@har dy:/bin# ln-sf bash/bin/sh root@hardy:/bin# ls-l/bin/sh lrwxrwxrwx 1 root root 4 2008-05-01 22:51/bin/sh-> bash as Do you want to know why Ubuntu uses the dash as the default shell, and look at this: a detailed explanation of the why dash is the defaults system shell. Step 7 adds users and groups, and modifies some configurations. This step is very important. If you are not very sure, do not change casually.

Note that the Oracle user's home directory is not the same as oracle_home. lines 19-23: Create a connection to some of the tools required by the Oracle installer. Because the Oracle installer is red HAt the ready, so some of the tools are not the same location as Ubuntu. Finally, on lines 24-25, creates the Oracle_base directory. Step 8 modifies some system default values. These modifications will increase the number of system file descriptors, increase the shared memory size, and modify some network subsystem parameters. Whether these changes will affect your system is unknown to me.

Point (Next) next. Modify specify operating System group name: "DBA" and then click "Next". Follow the diagram above to set the next point. Select "Enterprise Edition" and then next. Antu settings, next. Continue to the next step. Wait for the system to check, and don't worry about errors and warnings. Tick all non-"succeeded" that are checked to the next step. Select "Install Software only", and so on after loading and then through the DBCA to install the database, next. You can also choose Create a database in this step to install the databases. Set all groups to: DBA, next. Now you can point to "Install": The process will wait a long time, and the system slows down, so you'd better take a book and have a cup of coffee. Sometimes the system will become very slow, like to crash, this do not tube, and so he slowly installed. In this step do not remember to point "OK", need to do the following: (another terminal, with sudo su-switch to superuser) root@hardy:~#/u01/app/orainventory/ changing Permissions Of/u01/app/orainventory to 770. changing groupname of/u01/app/orainventory to DBA.
