## Install Oracle 8.1.7

By Vinod Kurup

OpenACS docs are written by the named authors, and may be edited by OpenACS documentation staff.

If you are installing PostGreSQL instead of Oracle, skip this section.

OpenACS 5.6.0 will install with Oracle 9i but has not been extensively tested so may still have bugs or tuning issues. See Andrew Piskorski's Oracle 9i notes for guidance.

This installation guide attempts to present all of the information necessary to complete an OpenACS installation. We try hard to make all of the steps possible in one pass, rather than having a step which amounts to "go away and develop a profound understanding of software X and then come back and, in 99% of all cases, type these two lines." The exception to our rule is Oracle production systems. This page describes a set of steps to get a working Oracle development server, but it is unsuitable for production systems. If you will be using OpenACS on Oracle in a production environment, you will experience many problems unless you develop a basic understanding of Oracle which is outside the scope of this document. T

This document assumes that you'll be installing Oracle on the same box as AOLserver. For more details on a remote Oracle installation, see Daryl Biberdorf's document.

### Acquire Oracle

Production Oracle systems should run on certified platforms. Follow the metalink note 223718.1to find certified platforms. If you don't have metalink access, take a look at the Oracle on Linux FAQ: Which Linux Distributions Are Directly Supported By Oracle?. In summary, free and inexpensive Linux distributions are not certified.

If you don't have an account at OTN get one: you can download the Oracle software from the Oracle Downloads page. It is also get the CDs shipped to you for a nominal fee from the Oracle Store.

Each Oracle release comes with extensive and usually quite well-written documentation. Your first step should be to thoroughly read the release notes for your operating system and your Oracle version. Find the docs here:

- Oracle 8i Release Documentation

- Oracle 9i Release Documentation

- Oracle 10g Release Documentation

It is generally useful to run a particular Oracle version with its latest patchset. At the time of writing these were 8.1.7.4 and 9.2.0.5, both of which are considered to be very stable.

To be able to download a patchset, you need a (to-pay-for) account on Metalink. You may find the appropriate patchset by following Andrew's suggestion.

### Things to Keep in Mind

Oracle is very well-documented software, the online documentation comes with printable PDFs and full-text search. Altogether there is more than 20.000 pages of documentation, so do not expect to understand Oracle within in a few hours. The best starting pointing into Oracle is the Concepts book. Here's the 8i version and the 9.2 version.

To give you an idea of how configurable Oracle is and how much thought you may need to put into buying the proper hardware and creating a sane setup, you should thoroughly read Cary Millsap's Configuring Oracle Server for VLDB and the Optimal Flexible Architecture standard.

Throughout these instructions, we will refer to a number of configurable settings and advise certain defaults. With the exception of passwords, we advise you to follow these defaults unless you know what you are doing. Subsequent documents will expect that you used the defaults, so a change made here will necessitate further changes later. For a guide to the defaults, please see Defaults.

In order for OpenACS to work properly you need to set the environment appropriately.

    export ORACLE_BASE=/ora8/m01/app/oracle
    export ORACLE_HOME=$ORACLE_BASE/product/8.1.7
    export PATH=$PATH:$ORACLE_HOME/bin
    export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
    export ORACLE_SID=ora8
    export ORACLE_TERM=vt100
    export ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data

    umask 022

    open_cursors = 500

    nls_date_format = "YYYY-MM-DD"

For additional resources/documentation, please see this thread and Andrew Piskorski's mini-guide.

### Pre-Installation Tasks

Though Oracle 8.1.7 has an automated installer, we still need to perform several manual, administrative tasks before we can launch it. You must perform all of these steps as the `root` user. We recommend entering the X window system as a normal user and then doing a `su -`. This command gives you full root access.

- Login as a non-root user and start X by typing `startx`

      [joeuser ~]$ startx

- Open a terminal window type and login as root

      [joeuser ~]$ su -
      Password: ***********
      [root ~]#

- Create and setup the `oracle` group and `oracle` account

  We need to create a user `oracle`, which is used to install the product, as well as starting and stopping the database.

      [root ~]# groupadd dba
      [root ~]# groupadd oinstall
      [root ~]# groupadd oracle
      [root ~]# useradd -g dba -G oinstall,oracle -m oracle
      [root ~]# passwd oracle

  You will be prompted for the New Password and Confirmation of that password.

- Setup the installation location for Oracle. While Oracle can reside in a variety of places in the file system, OpenACS has adopted `/ora8` as the base directory.

  Note: the Oracle install needs about 1 GB free on `/ora8` to install successfully.

      [root ~]# mkdir /ora8
      root:/ora8# cd /ora8
      root:/ora8# mkdir -p m01 m02 m03/oradata/ora8
      root:/ora8# chown -R oracle.dba /ora8
      root:/ora8# exit

- Set up the `oracle` user's environment

  - Log in as the user `oracle` by typing the following:

        [joeuser ~]$ su - oracle
        Password: ********

  - Use a text editor to edit the `.bash_profile` file in the `oracle` account home directory.

        [oracle ~]$ emacs .bash_profile

    You may get this error trying to start emacs:

        Xlib: connection to ":0.0" refused by server
        Xlib: Client is not authorized to connect to Server
        emacs: Cannot connect to X server :0.
        Check the DISPLAY environment variable or use `-d'.
        Also use the `xhost' program to verify that it is set to permit
        connections from your machine.

    If so, open a new terminal window and do the following:

        [joeuser ~]$ xhost +localhost

    Now, back in the oracle terminal:

        [oracle ~]$ export DISPLAY=localhost:0.0
        [oracle ~]$ emacs .bash_profile

    Try this procedure anytime you get an Xlib connection refused error.

  - Add the following lines (substituting your Oracle version number as needed) to `.bash_profile`:

        export ORACLE_BASE=/ora8/m01/app/oracle
        export ORACLE_HOME=$ORACLE_BASE/product/8.1.7
        export PATH=$PATH:$ORACLE_HOME/bin
        export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
        export ORACLE_SID=ora8
        export ORACLE_TERM=vt100
        export ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data

        umask 022

    Save the file by typing `CTRL-X CTRL-S` and then exit by typing `CTRL-X CTRL-C`. Alternatively, use the menus.

  Make sure that you do not add any lines like the following

      # NLS_LANG=american
      # export NLS_LANG

  These lines will change the Oracle date settings and will break OpenACS since OpenACS depends on the ANSI date format, YYYY-MM-DD dates.

- Log out as oracle

      [oracle ~]$ exit

- Log back in as `oracle` and double check that your environment variables are as intended. The `env` command lists all of the variables that are set in your environment, and `grep` shows you just the lines you want (those with ORA in it).

      [joeuser ~]$ su - oracle
      [oracle ~]$ env | grep ORA

  If it worked, you should see:

      ORACLE_SID=ora8
      ORACLE_BASE=/ora8/m01/app/oracle
      ORACLE_TERM=vt100
      ORACLE_HOME=/ora8/m01/app/oracle/product/8.1.7
      ORA_NLS33=/ora8/m01/app/oracle/product/8.1.7/ocommon/nls/admin/data

  If not, try adding the files to `~/.bashrc` instead of `.bash_profile`. Then logout and log back in again. Also, be certain you are doing `su - oracle` and not just `su oracle`. The `-` means that `.bashrc` and `.bash_profile` will be evaluated.

  Make sure that `/bin`, `/usr/bin`, and `/usr/local/bin` are in your path by typing:

      [oracle ~]$ echo $PATH
      /bin:/usr/bin:/usr/local/bin:/usr/bin/X11:/usr/X11R6/bin:/home/oracle/bin:/ora8/m01/app/oracle/product/8.1.7/bin

  If they are not, then add them to the `.bash_profile` by changing the PATH statement above to `PATH=$PATH:/usr/local/bin:$ORACLE_HOME/bin`

### Installing Oracle 8.1.7 Server

- Log in as `oracle` and start X if not already running. Start a new terminal:

      [joeuser ~]$ xhost +localhost
      [joeuser ~]$ su - oracle
      Password: **********
      [oracle ~]$ export DISPLAY=localhost:0.0

- Find the `runInstaller` script

  - If you are installing Oracle from a CD-ROM, it is located in the `install/linux` path from the cd-rom mount point

        [oracle ~]$ su - root
        [root ~]# mount -t iso9660 /dev/cdrom /mnt/cdrom
        [root ~]# exit
        [oracle ~]$ cd /mnt/cdrom

  - If you are installing from the tarball, the install script is located in the `Oracle8iR2` directory that was created when you expanded the archive.

        [oracle ~]$ cd /where/oracle/Disk1

  Check to make sure the file is there.

      oracle:/where/oracle/Disk1$ ls
      doc  index.htm  install  runInstaller  stage  starterdb

  If you don't see `runInstaller`, you are in the wrong directory.

- Run the installer

      oracle:/where/oracle/Disk1$ ./runInstaller

  A window will open that welcomes you to the 'Oracle Universal Installer' (OUI). Click on "`Next`"

  ### Note

  Some people have had trouble with this step on RedHat 7.3 and 8.0. If so, try the following steps before calling ./runInstaller:

  1. Execute the following command: /usr/i386-glibc21-linux/bin/i386-glibc21-linux-env.sh

  2. Type export LD_ASSUME_KERNEL=2.2.5

- The "File Locations" screen in the OUI:

  - "Source" path should have been prefilled with "(wherever you mounted the CDROM)`/stage/products.jar`"

  - "destination" path says "`/ora8/m01/app/oracle/product/8.1.7`"

    If the destination is not correct it is because your environment variables are not set properly. Make sure you logged on as `oracle` using `su - oracle`. If so, edit the `~/.bash_profile` as you did in Pre-Installation Tasks

  - Click "Next" (a pop up window will display Loading Product information).

- The "Unix Group Name" screen in the OUI:

  - The Unix Group name needs to be set to '`oinstall`' ( we made this Unix group earlier ).

  - Click "Next"

  - A popup window appears instantly, requesting you to run a script as root:

  - - Debian users need to link `/bin/awk` to `/usr/bin/awk` before running the script below

          [joueser ~]$ su -
          [root ~]# ln -s /usr/bin/awk /bin/awk

  - Open a new terminal window, then type:

        [joeuser ~]$ su -
        [root ~]# cd /ora8/m01/app/oracle/product/8.1.7
        [root ~]# ./orainstRoot.sh
        ; You should see:
        Creating Oracle Inventory pointer file (/etc/oraInst.loc)
        Changing groupname of /ora8/m01/app/oracle/oraInventory to oinstall.
        [root ~]# mkdir -p /usr/local/java
        [root ~]# exit
        [joeuser ~]$ exit

  - Click "Next"

- The "Summary" screen in the OUI

  - Check the "Space Requirements" section to verify you have enough disk space for the install.

  - Check that "(144 products)" is in the "New Installations" section title.

  - Click "Install"

  - A progress bar will appear for about 20 - 30 minutes. Now is a good time to take a break.

  - A "Setup Privileges" window will popup towards the end of the installation asking you to run a script as `root`

  - Run the script. Switch to the oracle user first to set the environment appropriately and then do su to get root privileges, while keeping the oracle user's enviroment.

        [joeuser ~]$ su - oracle
        Password: *********
        [oracle ~]$ su

Congratulations, you have just installed Oracle 8.1.7 Server! However, you still need to create a database which can take about an hour of non-interactive time, so don't quit yet.

### Creating the First Database

This step will take you through the steps of creating a customized database. Be warned that this process takes about an hour on a Pentium II with 128 MB of RAM.

### Note

RedHat 7.3 and 8.0 users: Before running dbassist, do the following.

1. Download the glibc patch from Oracle Technet into `/var/tmp`.

2. cd $ORACLE_HOME

3. tar xzf /var/tmp/glibc2.1.3-stubs.tgz

4. ./setup_stubs

- Make sure you are running X. Open up a terminal and `su` to oracle and then run the `dbassist` program.

      [joeuser ~]$ xhost +localhost
      [joeuser ~]$ su - oracle
      Password: *********
      [oracle ~]$ export DISPLAY=localhost:0.0
      [oracle ~]$ dbassist

- The "Welcome" screen in the Oracle Database Configuration Agent (ODCA)

  - Select "Create a database"

  - Click "Next"

- The "Select database type" screen in the ODCA

  - Select "Custom"

  - Click "Next"

- The "Primary Database Type" window in ODCA

  - Select "Multipurpose"

  - Click "Next"

- The "concurrent users" screen of the ODCA

  - Select "60" concurrent users.

  - Click "Next"

- Select "`Dedicated Server Mode`", click "`Next`"

- Accept all of the options, and click `Next` Oracle Visual Information Retrieval may be grayed out. If so, you can ignore it; just make sure that everything else is checked.

- For "Global Database Name", enter "`ora8`"; for "SID", also enter "`ora8`" (it should do this automatically). Click `"Change Character Set` and select `UTF8`. Click "`Next`".

- Accept the defaults for the next screen (control file location). Click "`Next`"

- Go to the "temporary" and "rollback" tabs, and change the Size (upper-right text box) to `150`MB. Click "`Next`"

- Increase the redo log sizes to `10000K` each. Click "`Next`"

- Use the default checkpoint interval & timeout. Click "`Next`"

- Increase "`Processes`" to `100`; "`Block Size`" to `4096` (better for small Linux boxes; use 8192 for a big Solaris machine).

- Accept the defaults for the Trace File Directory. Click "`Next`"

- Finally, select "`Save information to a shell script`" and click "`Finish`" (We're going to examine the contents of this file before creating our database.)

- Click the "`Save`" button. Oracle will automatically save it to the correct directory and with the correct file name. This will likely be `/ora8/m01/app/oracle/product/8.1.7/assistants/dbca/jlib/sqlora8.sh`

- It will alert you that the script has been saved successfully.

- Now we need to customize the database configuration a bit. While still logged on as `oracle`, edit the database initialization script (run when the db loads). The scripts are kept in `$ORACLE_HOME/dbs` and the name of the script is usually `init` SID`.ora` where SID is the SID of your database. Assuming your `$ORACLE_HOME` matches our default of `/ora8/m01/app/oracle/product/8.1.7`, the following will open the file for editing.

      [oracle ~]$ emacs /ora8/m01/app/oracle/product/8.1.7/dbs/initora8.ora

- Add the following line to the end:

      nls_date_format = "YYYY-MM-DD"

- Now find the `open_cursors` line in the file. If you're using `emacs` scroll up to the top of the buffer and do `CTRL-S` and type `open_cursors` to find the line. The default is `100`. Change it to `500`.

      open_cursors = 500

- Save the file. In emacs, do `CTRL-X CTRL-S` to save followed by `CTRL-X CTRL-C` to exit or use the menu.

- At this point, you are ready to initiate database creation. We recommend shutting down X to free up some RAM unless you have 256 MB of RAM or more. You can do this quickly by doing a `CRTL-ALT-BACKSPACE`, but make sure you have saved any files you were editing. You should now be returned to a text shell prompt. If you get sent to a graphical login screen instead, switch to a virtual console by doing `CRTL-ALT-F1`. Then login as `oracle`.

- Change to the directory where the database creation script is and run it:

      [oracle ~]$ cd /ora8/m01/app/oracle/product/8.1.7/assistants/dbca/jlib
      oracle:/ora8/m01/app/oracle/product/8.1.7/assistants/dbca/jlib$ ./sqlora8.sh

  In some instances, Oracle will save the file to `/ora8/m01/app/oracle/product/8.1.7/assistants/dbca` Try running the script there if your first attempt does not succeed.

- Your database will now be built. It will take > 1 hour - no fooling. You will see lots of errors scroll by (like: "ORA-01432: public synonym to be dropped does not exist") Fear not, this is normal.

  Eventually, you'll be returned to your shell prompt. In the meantime, relax, you've earned it.

### Acceptance Test

For this step, open up a terminal and `su` to `oracle` as usual. You should be running X and Netscape (or other web browser) for this phase.

- You need to download the "Oracle Acceptance Test" file. It's available here and at http://philip.greenspun.com/wtr/oracle/acceptance-sql.txt. Save the file to `/var/tmp`

- In the oracle shell, copy the file.

      [oracle ~]$ cp /var/tmp/acceptance-sql.txt /var/tmp/acceptance.sql

- Once you've got the acceptance test file all set, stay in your term and type the following:

      [oracle ~]$ sqlplus system/manager

  SQL*Plus should startup. If you get an `ORA-01034: Oracle not Available` error, it is because your Oracle instance is not running. You can manually start it as the `oracle` user.

      [oracle ~]$ svrmgrl
      SVRMGR> connect internal
      SVRMGR> startup

- Now that you're into SQL*Plus, change the default passwords for system, sys, and ctxsys to "alexisahunk" (or to something you'll remember):

      SQL> alter user system identified by alexisahunk;
      SQL> alter user sys identified by alexisahunk;
      SQL> alter user ctxsys identified by alexisahunk;

- Verify that your date settings are correct.

      SQL> select sysdate from dual;

  If you don't see a date that fits the format `YYYY-MM-DD`, please read Troubleshooting Oracle Dates.

- At this point we are going to hammer your database with an intense acceptance test. This usually takes around 30 minutes.

      SQL> @ /var/tmp/acceptance.sql

      ; A bunch of lines will scroll by.  You'll know if the test worked if
      ; you see this at the end:

      SYSDATE
      ----------
      2000-06-10

      SQL>

  Many people encounter an error regarding `maximum key length`:

      ERROR at line 1:
      ORA-01450: maximum key length (758) exceeded

  This error occurs if your database block size is wrong and is usually suffered by people trying to load OpenACS into a pre-existing database. Unfortunately, the only solution is to create a new database with a block size of at least `4096`. For instructions on how to do this, see Creating the First Database above. You can set the parameter using the `dbassist` program or by setting the `DB_BLOCK_SIZE` parameter in your database's creation script.

  If there were no errors, then consider yourself fortunate. Your Oracle installation is working.

### Automating Startup & Shutdown

You will want to automate the database startup and shutdown process. It's probably best to have Oracle spring to life when you boot up your machine.

- Oracle includes a script called `dbstart` that can be used to automatically start the database. Unfortunately, the script shipped in the Linux distribution does not work out of the box. The fix is simple. Follow these directions to apply it. First, save dbstart to `/var/tmp`. Then, as `oracle`, do the following:

      [oracle ~]$ cp /var/tmp/dbstart.txt /ora8/m01/app/oracle/product/8.1.7/bin/dbstart
      [oracle ~]$ chmod 755 /ora8/m01/app/oracle/product/8.1.7/bin/dbstart

- While you're logged in as `oracle`, you should configure the `oratab` file to load your database at start. Edit the file `/etc/oratab`:

  - You will see this line.

        ora8:/ora8/m01/app/oracle/product/8.1.7:N

    By the way, if you changed the service name or have multiple databases, the format of this file is:

    `service_name:$ORACLE_HOME:Y || N (for autoload)`

  - Change the last letter from "N" to "Y". This tells Oracle that you want the database to start when the machine boots. It should look like this.

        ora8:/ora8/m01/app/oracle/product/8.1.7:Y

  - Save the file & quit the terminal.

- You need a script to automate startup and shutdown. Save oracle8i.txt in `/var/tmp`. Then login as `root` and install the script. (Debian users: substitute `/etc/init.d` for `/etc/rc.d/init.d` throughout this section)

      [oracle ~]$ su -
      [root ~]# cp /var/tmp/oracle8i.txt /etc/rc.d/init.d/oracle8i

- You also need some scripts to automate startup and shutdown of the Oracle8i listener. The listener is a name server that allows your Oracle programs to talk to local and remote databases using a standard naming convention. It is required for Intermedia Text and full site search.

  Download these three scripts into `/var/tmp`

  - startlsnr.txt

  - stoplsnr.txt

  - listener8i.txt

  Now issue the following commands (still as `root`).

      [root ~]# su - oracle
      [oracle ~]$ cp /var/tmp/startlsnr.txt /ora8/m01/app/oracle/product/8.1.7/bin/startlsnr
      [oracle ~]$ cp /var/tmp/stoplsnr.txt /ora8/m01/app/oracle/product/8.1.7/bin/stoplsnr
      [oracle ~]$ chmod 755 /ora8/m01/app/oracle/product/8.1.7/bin/startlsnr
      [oracle ~]$ chmod 755 /ora8/m01/app/oracle/product/8.1.7/bin/stoplsnr
      [oracle ~]$ exit
      [root ~]# cp /var/tmp/listener8i.txt /etc/rc.d/init.d/listener8i
      [root ~]# cd /etc/rc.d/init.d
      root:/etc/rc.d/init.d# chmod 755 listener8i

  Test the listener automation by running the following commands and checking the output.

      root:/etc/rc.d/init.d# ./listener8i stop
      Oracle 8i listener start/stop

  This test will verify that the listener is operating normally. Login into the database using the listener naming convention.

  `sqlplus` `username/password/@SID`

      [root ~]# su - oracle

  - RedHat users:

    Now run `chkconfig` on the `listener8i` script.

        [root ~]# cd /etc/rc.d/init.d/
        root:/etc/rc.d/init.d# chkconfig --add listener8i

    Now run `update-rc.d` on the `listener8i` script.

        [root ~]# update-rc.d listener8i defaults 21 19
         Adding system startup for /etc/init.d/listener8i ...

           /etc/rc5.d/S21listener8i -> ../init.d/listener8i

- Test the automation

  As a final test, reboot your computer and make sure Oracle comes up. You can do this by typing

      [root ~]# /sbin/shutdown -r -t 0 now

  Log back in and ensure that Oracle started automatically.

      [joeuser ~]$ su - oracle
      [oracle ~]$ sqlplus system/alexisahunk@ora8

      SQL> exit

Congratulations, your installation of Oracle 8.1.7 is complete.

### Troubleshooting Oracle Dates

Oracle has an internal representation for storing the data based on the number of seconds elapsed since some date. However, for the purposes of inputing dates into Oracle and getting them back out, Oracle needs to be told to use a specific date format. By default, it uses an Oracle-specific format which isn't copacetic. You want Oracle to use the ANSI-compliant date format which is of form `'YYYY-MM-DD'`.

To fix this, you should include the following line in `$ORACLE_HOME/dbs/init` SID`.ora` or for the default case, `$ORACLE_HOME/dbs/initora8.ora`

    nls_date_format = "YYYY-MM-DD"

You test whether this solved the problem by firing up `sqlplus` and typing:

    SQL> select sysdate from dual;

You should see back a date like `2000-06-02`. If some of the date is chopped off, i.e. like `2000-06-0`, everything is still fine. The problem here is that `sqlplus` is simply truncating the output. You can fix this by typing:

    SQL> column sysdate format a15
    SQL> select sysdate from dual;

If the date does not conform to this format, double-check that you included the necessary line in the init scripts. If it still isn't working, make sure that you have restarted the database since adding the line:

    [joeuser ~]$ svrmgrl
    SVRMGR> connect internal
    Connected.
    SVRMGR> shutdown
    Database closed.
    Database dismounted.
    ORACLE instance shut down.
    SVRMGR> startup
    ORACLE instance started.

If you're sure that you have restarted the database since adding the line, check your initialization scripts. Make sure that the following line is not included:

    export nls_lang = american

Setting this environment variable will override the date setting. Either delete this line and login again or add the following entry to your login scripts after the `nls_lang` line:

    export nls_date_format = 'YYYY-MM-DD'

Log back in again. If adding the `nls_date_format` line doesn't help, you can ask for advice in our OpenACS forums.

### Useful Procedures

- Dropping a tablespace

  - Run sqlplus as the dba:

        [oracle ~]$ sqlplus system/changeme

  - To drop a user and all of the tables and data owned by that user:

        SQL> drop user oracle_user_name cascade;

  - To drop the tablespace: This will delete everything in the tablespace overriding any referential integrity constraints. Run this command only if you want to clean out your database entirely.

        SQL> drop tablespace table_space_name including contents cascade constraints;

For more information on Oracle, please consult the documentation.

### Oracle Next Steps

Creating an appropriate tuning and monitoring environment

### Defaults

We used the following defaults while installing Oracle.

Variable | Value | Reason
--- | --- | ---
ORACLE_HOME | /ora8/m01/app/oracle/product/8.1.7 | This is the default Oracle installation directory.
ORACLE_SERVICE | ora8 | The service name is a domain-qualified identifier for your Oracle server.
ORACLE_SID | ora8 | This is an identifier for your Oracle server.
ORACLE_OWNER | oracle | The user who owns all of the oracle files.
ORACLE_GROUP | dba | The special oracle group. Users in the dba group are authorized to do a `connect internal` within `svrmgrl` to gain full system access to the Oracle system.
