Installation

Retain can be downloaded from http://download.gwava.com/download.php?product=Retain&version=versions.

Before you install Retain, there are some other pieces required depending upon the operating system. The reason for this is Retain runs under the Tomcat environment and Tomcat requires Java.

Ignore Retain Minimum Memory Settings

When installing Retain, to ignore the minimum memory settings (less than 12 GB) during the install, add the following switches:

SLES

./RetainInstall.sh -IgnoreMemoryCheck

Windows

in windows you need to start it with the command prompt .\RetainInstall.exe /IgnoreMemoryCheck

This may primarily affect Retain 4.0.1 for a memory check.

Retain Installation on SLES

• Install Apache2.2
• Install your database management system (DBMS - i.e., MySQL, MS SQL, Oracle, etc).

• If using MySQL, Retain will install and configure a "retain" database for you; however, you must first download the MySQL 5.5 server and client RPMs. They must be accessible to the Retain installation program, so it is best if the RPMs are on a drive local to the installer. It is easier if you download the MySQL "bundle" SLES 11 x64. Retain only needs the server and client, but downloading the bundle is for convenience - it prevents you from having to download the server and then download the client separately.
• If using MS SQL or Oracle, you will need to create the "retain" database in advance. See the appendix of the Linux Install Guide for instructions.

Retain Installation on Windows Server

• Install Apache2.2 or IIS
• Download Java from the GWAVA download website and install it.
• Install your database management system (DBMS - i.e., MySQL, MS SQL, Oracle, etc) and configure a "retain" database. See the appendix of the Windows Install Guide for instructions.

Typical Post-Install Oversight - Linux

If you do not go with the default storage paths that Retain defaults to (which is perfectly OK), then you'll need to assign ownership of the directory to "tomcat" after installing Retain but before you access the RetainServer web interface for the first time (to configure your Retain system).

For example, if my Retain storage path were going to be "/data", I would first install Retain so that Tomcat gets installed. Tomcat would have to be installed and registered on the server before you could assign it as a directory owner. To assign "tomcat" as the owner of "/data", I would type this command: chown tomcat:tomcat /data.

If you miss this step, Retain will not be able to write files to your storage directory.
