This guide describes how to install and license the Omnidex software on a Linux operating system.
There are two methods of installing Omnidex. Many system administrators like to use the 'yum' facility to automatically install Omnidex. Others will prefer to manually download and install the RPM files. Both approaches are supported.
Omnidex should be installed using the 'root' system user. Alternatively, Omnidex can be installed with the sudo command.
The Omnidex repository needs to be declared on your system. The following Linux commands will install the Omnidex repository file.
For Red Hat or CentOS 6.x versions:
# wget http://www.disc.com/download/omnidex/Linux/6/omnidex.repo -P /etc/yum.repos.d
For Red Hat or CentOS 5.x versions:
# wget http://www.disc.com/download/omnidex/Linux/5/omnidex.repo -P /etc/yum.repos.d
Once the Omnidex repository is installed, Omnidex can be easily installed using the command:
# yum install omnidex
You can update an existing version of Omnidex using the command:
# yum update omnidex
Omnidex should be installed using the 'root' system user. Alternatively, Omnidex can be installed with the sudo command.
If a previous version of Omnidex has been installed without using RPM, please remove this version of the software before proceeding.
Note that if you have installed Omnidex on databases, it is not necessary to remove the Omnidex indexes on those databases before installing a new version of Omnidex. The existing indexes may be able to be reused.
Download the software from the Downloads tab in this documentation. Be sure to choose correctly between the 32-bit and 64-bit versions of the software.
Omnidex is available as an RPM file or as a TAR file. Both installations contain the same Omnidex software.
Omnidex is most easily installed using the RPM format. While logged on as the 'root' user, use the rpm command to install the software. Note that the exact filename will be different for each version of Omnidex.
# rpm -Uvf omnidex-5.3-07H.el6.linux.x86_64.rpm Preparing packages for installation... omnidex-5.3-07H.el6.linux #
The Omnidex installation performs the following tasks:
To use Omnidex with Java, you must set these environment variables:
export LD_LIBRARY_PATH="opt/omnidex/lib:$LD_LIBRARY_PATH" export CLASSPATH="/opt/omnidex/lib/Omnidex.jar:$CLASSPATH"
To use OdxSQL as a Java client for testing purposes, you also must add the directory containing libjvm.so to LD_LIBRARY_PATH.
Omnidex is usually run as a service, though it can be run in a console window as well. The files needed to set up Omnidex as a service are automatically placed in /etc/init.d upon installation.
The following commands are available to manage the Omnidex service:
service omnidexd start (start omnidex as a service) service omnidexd stop (stop omnidex as a service) service omnidexd restart (restart omnidex as a service) service omnidexd status (check if omnidex is running as a service)
To manage whether the Omnidex service starts every time the system is rebooted, use the following commands:
chkconfig --add omnidexd (add omnidex service to startup) chkconfig --del omnidexd (remove omnidex service from startup) chkconfig --list omnidexd (check if omnidex service is in the startup)
If you have any difficulty installing Omnidex on your Linux operating system, please contact Technical Support for assistance.
