 ==== Linux Installation Guide ====
-This guide describes how to install and license the Omnidex software on a Linux operating system.
+This guide describes how to install and license the Omnidex software on a Linux operating system.  The Omnidex installation performs the following tasks:
+  - Copy the Omnidex files into /opt/omnidex directory.
+  - Create symbolic links in /usr/bin for odxsql, odxnet, omnidex, and odxversions.
+  - Create omnidex.conf file in /etc/ld.so.conf.d directory.  The file omnidex.conf contains the path to the Omnidex libraries (/opt/omnidex/lib).
 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.
-=== Installing Omnidex automatically using YUM ===
+=== Automatic installation ===
-== 1. Make sure that the Omnidex repository is declared on your server ==
+== 1. Log on as root ==
-== 2. Install Omnidex ==
+Omnidex should be installed using the 'root' system user.  Alternatively, Omnidex can be installed with the sudo command.
-=== Installing Omnidex manually using YUM ===
+== 2. Make sure that the Omnidex repository is installed on your server ==
-== 1. Remove any previous non-RPM installations of Omnidex ==
+The Omnidex repository must be copied to your system.  The following Linux command will copy the Omnidex repository file.
-If a previous version of Omnidex has been installed without using RPM, please remove this version of the software before proceeding.
+For Red Hat or CentOS 6.x versions:
-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.
+  # wget http://www.omnidex.com/downloads/omnidex/Linux/el6/omnidex.repo -P /etc/yum.repos.d
-== 2. Downloading the software ==
-[[install:downloads:home|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.
+For Red Hat or CentOS 5.x versions:
-Omnidex is available as an RPM file or as a TAR file.  Both installations contain the same Omnidex software.
+  # wget http://www.omnidex.com/downloads/omnidex/Linux/el5/omnidex.repo -P /etc/yum.repos.d
+For SuSE versions:
+  # wget http://www.omnidex.com/downloads/omnidex/Linux/el6/omnidex.repo -P /etc/zypp/repos.d
+== 3. Choose whether to use the latest stable version or the current development version ==
+By default, yum will install the latest stable version of Omnidex, suitable for production applications.  If you would like to access the most recent development version or a previous version of Omnidex, you must edit the Omnidex repository.
+The repository contains three sections:
+  * [omnidex] - The most recent stable version of Omnidex, suitable for production applications.
+  * [omnidex-devel] - The most recent development version of Omnidex containing the latest features and bug fixes.
+  * [omnidex-arch] - An archive of previous versions of Omnidex.
+Choose which section you want to activate by setting "enabled = 1" for that section and "enabled = 0" for all other sections.
+== 3. Install Omnidex ==
+For Red Hat or CentOS versions:
+Once the Omnidex repository is copied, Omnidex can be automatically installed using the command:
+  # yum install omnidex
+You can update an existing version of Omnidex using the command:
+  # yum update omnidex
+You can remove an existing version of Omnidex using the command:
+  # yum remove omnidex
+If your repository is set to [omnidex-arch] as described above, you can view all available versions and install a particular version using the commands:
+  # yum list --showduplicates omnidex
+  # yum install omnidex-<version>  (eg. yum install omnidex-5.3-08D.el6.linux)
+Note: To install an earlier version of Omnidex than the version currently installed, first remove Omnidex and then clear the yum cache.
+  # yum remove omnidex
+  # yum clean metadata
+For SuSE versions:
+Once the Omnidex repository is copied, Omnidex can be automatically installed using the command:
+  # zypper install omnidex
+You can update an existing version of Omnidex using the command:
+  # zypper update omnidex
+You can remove an existing version of Omnidex using the command:
+  # zypper remove omnidex
+If your repository is set to [omnidex-arch] as described above, you can view all available versions and install a particular version using the commands:
+  # zypper packages omnidex
+  # zypper install omnidex-<version>  (eg. zypper install omnidex-5.3-08D.el6.linux)
+Note: To install an earlier version of Omnidex than the version currently installed, first remove Omnidex and then clear the yum cache.
+  # zypper  remove omnidex
+  # zypper  clean
+=== Manual installation ===
-== 3. Log on as root ==
+== 1. Log on as root ==
 Omnidex should be installed using the 'root' system user.  Alternatively, Omnidex can be installed with the sudo command.
+== 2. Remove any previous non-RPM installations of Omnidex ==

 To use OdxSQL as a Java client for testing purposes, you also must add the directory containing libjvm.so to LD_LIBRARY_PATH.
+Additionally, it is recommended to set LD_PRELOAD to Java's libjsig.so library due to known compatibility issues with Java's signal handling with other applications, including Omnidex. This is necessary to avoid unexplained aborts of the JVM when connecting to Omnidex processes, such as when setting up application pooling using DBCP.
