6.6. UNIX & Linux Install
Ensure you have downloaded all of the relevant OpenLink Server Components from the page created by the OpenLink Software Download wizard, this must include the OpenLink Server Components Installation shell script file "install.sh" in addition to the compressed "tar" archives for the OpenLink Request Broker and relevant Database Agent Components.
From the OpenLink email that is delivered at the time of download, save the attached license file to the same location as the install.sh.
Log on to your Database or Application server machine using the userid and password combination that you normally use when connecting to the database in non ODBC/JDBC/UDBC mode.
Determine your operating system group membership by typing in the command:
The "gid" value indicates your current operating system group membership (remember this for use later on during the installation process).
Create an OpenLink installation directory on the server (e.g., /usr/openlink) and transfer to it all the server component files you downloaded (including compressed TAZ archives and the installation shell script "install.sh").
Do not uncompress or unzip the compressed .taz archives after download; the installation script will take care of this for you.
If using FTP, be sure to transfer the compressed .taz archives in BINARY mode, and the installation shell script in TEXT mode.
You set your FTP program in TEXT or ASCII transfer mode by typing the following command at your FTP command prompt:
You set your FTP program in BINARY transfer mode by typing the following command at your FTP command prompt:
The file "install.sh" is an "sh" shell script. It must be executed in the appropriate shell to avoid unexpected behaviour. Run the "install.sh" script on the server by typing the command:
The install script will extract the files from the ".taz" files and then create all of the relevant OpenLink server component sub-directories. The install script will also place the OpenLink server components into their appropriate sub-directories
Once the files have been extracted and placed in the relevant sub-directories, the install script will proceed to install and configure the OpenLink Admin Assistant. This program enables remote configuration for all OpenLink Server Components (Rule Book, Service and Database Agents) from any Web Browser.
The dialogue below illustrates the interactions encountered during the server components installation process, accepting all the script defaults:

Run the OpenLink environment shell script as follows:
Users in tcsh or csh must use the command:
This will set all the required environment variables (e.g., $ODBCINI, $ODBCINSTINI, $PATH) which enable alternate directory executable launching, and proper use of the HTTP-based Admin Assistant.
You may wish to place the startup command in your shell startup script (.profile, .login, .bashrc etc) in order for it to take effect on login.
Start your OpenLink Request Broker in debug mode by executing the OpenLink Request Broker startup command:
Should you receive an "oplrqb: unable to create listener (Address already in use)" error, this most likely indicates that the Broker is already started. It can be shut down by running the command:
oplshut +port <alternate port number>
Where <alternate port number>> is a different port number you specified as the Broker's TCP listen port at install-time. (If you used the default port, then use the former command.)
If you continue to receive the error above, the port (either 5000, or the one you specified as the Listen port) is already occupied by another TCP process. Contact your systems administrator for assistance, or reinstall the OpenLink Request Broker, specifying a different TCP Listen port.
Start your Web Browser and then enter the following URL:
Where host is the network alias or IP address of machine where Server Components are installed. The port is the number you provided when prompted by OpenLink installer.
For example, if your machine has a network alias of "opllinux", and you accept the default port number at installation time, then the required URL would be constructed as follows:
Follow the instructions provided in the "Client Components Installation" section of this guide, in order to verify connectivity to your server using the OpenLink Multi-Tier Data Access Drivers.
If the previous step is successful, shut down the Request Broker using the command:
This will kill off any remaining connections to the database, if they have been established. Next restart in normal mode using the command:
Running your Request Broker in debug mode will log a significant amount of information to the bin/oplrqb.log file, so normal mode is recommended unless you are experiencing problems which you need to report to Technical Support.
For more information about other available options when starting and stopping the Request Broker, see the "Request Broker Startup & Shutdown" topic in the Server Components Administration section of this guide.
