If you are installing PostGreSQL instead of Oracle, skip this section.
OpenACS 5.5.0 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.
Useful links to find help on how to set up Oracle under Linux are:
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:
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.
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 the section called “Defaults”.
In order for OpenACS to work properly you need to set the environment appropriately.

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:$ORACLE_HOME/bin
Log in as oracle and
start X if not already running. Start a new terminal:
[joeuser ~]$ 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"
Some people have had trouble with this step on RedHat 7.3 and 8.0. If so, try the following steps before calling ./runInstaller:
Execute the following command: /usr/i386-glibc21-linux/bin/i386-glibc21-linux-env.sh
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 the section called “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.

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.

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.
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.
RedHat 7.3 and 8.0 users: Before running dbassist, do the following.
Download the glibc
patch from Oracle Technet into /var/tmp.
cd $ORACLE_HOME
tar xzf /var/tmp/glibc2.1.3-stubs.tgz
./setup_stubs
Make sure you are running X. Open up a terminal and
su to oracle and then run the
dbassist program.
[joeuser ~]$ xhost +localhost [joeuser ~]$ su - oracle Password: ********* [oracle ~]$ export DISPLAY=localhost:0.0 [oracle ~]$ dbassist
The "Welcome" screen in the Oracle Database Configuration Agent (ODCA)

The "Select database type" screen in the ODCA
Select "Custom"
Click "Next"
The "Primary Database Type" window in ODCA
Select "Multipurpose"

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
150MB. 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
initSID.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.
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 the section called “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 the section called “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.
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 [root ~]# chown root.root /etc/rc.d/init.d/oracle8i [root ~]# chmod 755 /etc/rc.d/init.d/oracle8i
Test the script by typing the following commands and checking the
output. (Debian Users: as root, do mkdir
/var/lock/subsys first)
[root ~]# /etc/rc.d/init.d/oracle8i stop

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
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

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.
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/initSID.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.
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.
We used the following defaults while installing Oracle.
