-===== Linux Installation Guide ======
+====== Software Installation: Installation Guides ======
-This guide describes how to install and license the Omnidex software on a Linux operating system.
+[[install:guides:windows|Microsoft Windows]] | **[[install:guides:linux|Linux]]**
+----
-==== Part 1. Create an Omnidex user account ====
+==== Linux Installation Guide ====
-Omnidex should be installed in its own user account on the Linux system.  Typically, Omnidex is installed using a user named "omnidex"; however, this is not required.
+This guide describes how to install and license the Omnidex software on a Linux operating system.  The Omnidex installation performs the following tasks:
-==== Part 2. Downloading the software ====
+  - 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).
-[[install:downloads|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.
+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.
-==== Part 3. Extract the software from the downloaded TAR file ====
+=== Automatic installation ===
-The downloaded software is in TAR format.  While logged on as the Omnidex user, use the tar command to extract the software.
+== 1. Log on as root ==
-  tar -xvf <filename>
+Omnidex should be installed using the 'root' system user.  Alternatively, Omnidex can be installed with the sudo command.
-==== Part 4. Run "odxmake", the Omnidex linkage script ====
+== 2. Make sure that the Omnidex repository is installed on your server ==
-The "odxmake" script is a UNIX Korn Shell script that will build the Omnidex software. It modifies the .profile file to support Omnidex, and creates the executable files from files loaded onto the system when the software was downloaded and extracted.
+The Omnidex repository must be copied to your system.  The following Linux command will copy the Omnidex repository file.
-//Note: Because of variations in the DBMS vendor's installations and location of installed files, the odxmake file may fail during the linkage process. Please contact [[appendix:contactus|Technical Support]] Technical Support to help determine site specific installation issues. //
+For Red Hat or CentOS 6.x versions:
+  # wget http://www.omnidex.com/downloads/omnidex/Linux/el6/omnidex.repo -P /etc/yum.repos.d
-== Step 1 ==
-Installation Omnidex requires three steps:
+For Red Hat or CentOS 5.x versions:
-  - [[install:downloads|Download]] the software from the Downloads tab in this documentation.
+  # wget http://www.omnidex.com/downloads/omnidex/Linux/el5/omnidex.repo -P /etc/yum.repos.d
-  - Extract the software from the downloaded .tar file.
-  - Create the omnidex user account on the computer.
-  - Run "odxmake" to install the software.
-==== Installing Omnidex on a Linux Operating Systems ====
+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 ===
+== 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 ==
+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.
+== 3. Download the software ==
+[[install:downloads:home|Download]] the software from the Downloads tab in this documentation.  Be sure to choose correctly the version of Omnidex that matches your version of Linux.
+Omnidex is available as an RPM file or as a TAR file.  Both installations contain the same Omnidex software.
+== 4. Install the Omnidex RPM file ==
+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.
+<code>
+  # rpm -Uvf omnidex-5.3-07H.el6.linux.x86_64.rpm
+  Preparing packages for installation...
+  omnidex-5.3-07H.el6.linux
+</code>
+=== Prepare Omnidex for use with Java (optional) ===
+To use Omnidex with Java, you must set these environment variables:
+<code>
+  export CLASSPATH="/opt/omnidex/lib/Omnidex.jar:$CLASSPATH"
+  export LD_LIBRARY_PATH="opt/omnidex/lib:$LD_LIBRARY_PATH"
+  export LD_PRELOAD="<see below>"
+</code>
+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. Instructions for setting this variable can be found at the following link:
+https://docs.oracle.com/javase/8/docs/technotes/guides/vm/signal-chaining.html
+=== Install Omnidex to run as a service (optional) ===
+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:
+<code>
+  systemctl start omnidexd         (start omnidex as a service)
+  systemctl stop omnidexd          (stop omnidex as a service)
+  systemctl restart omnidexd       (restart omnidex as a service)
+  systemctl status omnidexd        (check if omnidex is running as a service)
+</code>
+To manage whether the Omnidex service starts every time the system is rebooted, use the following commands:
+<code>
+  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)
+</code>
