Introduction
Installation
9iAS infrastructure Installation
Oracle Collaboration Suite Information Storage Installation
Oracle Collaboration Suite Middle-Tier Installation
Summary
Further Reading/Other resources
This is the second half of the brief guide to installing Oracle Collaboration Suite Relase 2 on Linux . Last month's issue looked at the resources required for installing Oracle Collaboration Suite, this month we're going to look at the installation process itself. This guide is not intended to be used instead of Oracle's installation guide but in conjunction with it.
Oracle Collaboration Suite conisists of Oracle 9iAS Infrastructure, Oracle 9i Collaboration Suite Information Storage (an Oracle 9i database) and Oracle 9i Collaboration Suite Middle Tier (the applications, including email, file sharing, ultra search, calendar) each of which has to be installed and configured separately, but this does allow you to install each product on a different server for load balancing, if required.
If you would like more information about Oracle Collaboration Suite, see the resources section which not only has recommendations and reviews of good books for further reading, but also contains links to information on OTN and other useful resources such as sample certification exam questions and certification study material.
For articles on general Oracle performance tuning, Oracle8 New Features and Oracle 9i New Features, etc. just go to: oracle tips and tricks .

The first step is to install the 9iAS infrastructure. This is a relatively straight-forward installation – just remember to make a note of the following information which you will need later on in the installation process:
To start the installation process insert the first disk of the 9iAS software set (and mount if necessary), then “/mount/cdrom/runInstaller”, follow the instructions, inserting the other disks as necessary and keeping record as mentioned above of all the choices made.
Part of the installation process is to install an Oracle database – this is used soley as the repository for Oracle Internet Dirctory (OID) and is not for use as the information store or the repository for the middle tier.
After installation, check the infrastructure is operating correctly by accessing
the following URLs: http://<single-sign-on
host name>:7777/pls/orasso
http://<internet directory host
name>:7777/oiddas
Note the host names must be fully qualified
eg. http://db.smart-soft.co.uk:7777/pls/orasso
rather than http://db:7777/pls/orasso
This is the second phase of the installation process and must be completed successfully before installation of the mid-tier (the applications) begins,but before continuing with the installation of the information store shut down all the infrastructure services and take a backup of everything below $ORACLE_BASE. That way if anything should go wrong in subsequent installatons you can go back to a clean state relatively quickly.
See start_stop_infra.sh for instructions to start and stop the infrastructure layer (ie. 9IAS). Note that OC4J_demos and home are not required and therefore do not need to be started.
The Information Storage component is essentially an Oracle database i.e. (Oracle 9i R2 Enterprise Server Edition) which makes the installation of this component straightforward. Remember to use a different Oracle Home directory from the infrastructure installation (this is important) and to keep a note of the passwords for the sys and system accounts when the database is created. If any of the configuration assistants hang or fail during the installation process then open a new window and run them manually. That way any subsequent configuration assistants will be run automatically. After installation, extra tablespaces can be added for Oracle Files if required.
The database should be registered with the Oracle Internet Directory automatically as part of the installation process but if this fails follow the instructions in the installation guide to register the information store. If the information storage layer is on the same server as one of the other layers it is best to give it its own listener so that the listener can be started and stopped independently of the listeners for the other components.
To start the installation process insert the first disk of the 9i Enterprise Server software set (and mount if necessary), then type /mount/cdrom/runInstaller, follow the instructions, inserting the other disks as necessary and keeping record as mentioned above of all the choices made.
After the installation process has completed, ensure that the database and the listener are running by connecting as sysdba and then seleting the time (or anything else) from dual. If the database is not running, the message “Connected to an idle instance” will be displayed as soon as you connect. In that case start the database by issuing the command startup.
Before continuing with the installation of the middle tier, shut down all the infrastructure services and the information store database and take a backup of everything below $ORACLE_BASE on the infrastucture server(s) and the information store server. That way if anything should go wrong in subsequent installatons you can go back to a clean state relatively quickly and easily.
This is the third and final phase of the installation process and must be started only after the infrastructure and database have been installed successfully. Ensure that the infrastructure layer and the information store are both running before starting the mid-tier installation (see Appendix A for details of starting and stopping the infrastructure layer and Appendix B for starting and stopping the information store). Also ensure that both PATH and LD_LIBRARY_PATH are set as specified in this document and the installation guide and that the kernel parameters have been set. Setting these will ensure that the installation process goes smoothly.
To start the installation process insert the first disk of the 9i Enterprise Server software set (and mount if necessary), then type /mount/cdrom/runInstaller, follow the instructions, inserting the other disks as necessary and keeping a record of the choices made and the passwords etc. This installation also creates a database to act as the repository for middle tier configurations – this database must be seperate from the infrastructure repository and the information storage database. When the installation prompts for a name for the repository, it is the name for the new repository that is required not the name of the existing infrastructure repository.
During installation of Oracle Files, specify the HTTP port to be 7778 Again, if any of the configuration assistants hang or fail during the installation process then open a new window and run them manually, don't kill or exit from the Universal Installer as this will mean that all the remaining configuration assistants will have to be run manually and the commands for running them from the command line are difficult to find.
Before continuing with the configuration of the mid-tier, it is a good idea to take a take a backup of everything below $ORACLE_BASE (after having shut down all the mid-tier and infrastructure services (see Appendix A and B).
After installation follow the instructions in the installation and configuration guide for configuring the unified messaging (email), calendar, files and other components.
LISTENER_ES – the email listener process - has to be started by Root and set to run in the background. If the listener fails to start or errors are displayed when the status of the listener is queried, check that sendmail and the SMTP daemon have been stopped. This is needed because the SMTP daemon listens on port 25 which is the same port that LISTENER_ES wants to use. As it is listening on a privileged port, the listener process has to be started by Root and can't be started using the usual method via LSNRCTL.
When configuring Oracle Files, create a new user to be the Files administrator otherwise if an existing user is specified this causes strange effects for that user. To fix Ultra Search see Note 245919.1 and bug 2972907on Metalink
Each of the components of Oracle Collaboration Suite have to be installed and configured separately thus the configuration of one part can affect the configuration of another. The best way of ensuring a success installation, is preparation - make sure the system requirements are met, that you have all the necessary patches (both for Red Hat and Oracle), decide which tiers are going to be used for which component, and that you have read Oracle's installation guides to get the big picture.
