Always check docs.netapp.com for the latest. Table of Contents Configuring UNIX-specific settings: Creating symbolic links . 1 Creating symbolic links for the Domino plug-in on Linux and Solaris hosts. 1 Creating symbolic links for the Domino plug-in on AIX hosts. 2 Configuring UNIX-specific settings: Creating symbolic links If you are going to install the Snap Creator Agent on a UNIX operating system (AIX, Linux, and Solaris), for the IBM Domino plug-in to work properly, three symbolic links (symlinks) must be created to link to Domino’s shared object files. Installation procedures vary slightly depending on the operating system. Refer to the appropriate procedure for your operating system. Domino does not support the HP-UX operating system. Creating symbolic links for the Domino plug-in on Linux and Solaris hosts You need to perform this procedure if you want to create symbolic links for the Domino plug-in on Linux and Solaris hosts. You should not copy and paste commands directly from this document; errors (such as incorrectly transferred characters caused by line breaks and hard returns) might result. Copy and paste the commands into a text editor, verify the commands, and then enter them in the CLI console. The paths provided in the following steps refer to the 32-bit systems; 64-bit systems must create simlinks to /usr/lib64 instead of /usr/lib. -
DC Console Using DC Console Application Design Software
DC Console Using DC Console Application Design Software DC Console is easy-to-use, application design software developed specifically to work in conjunction with AML’s DC Suite. Create. Distribute. Collect. Every LDX10 handheld computer comes with DC Suite, which includes seven (7) pre-developed applications for common data collection tasks. Now LDX10 users can use DC Console to modify these applications, or create their own from scratch. AML 800.648.4452 Made in USA www.amltd.com Introduction This document briefly covers how to use DC Console and the features and settings. Be sure to read this document in its entirety before attempting to use AML’s DC Console with a DC Suite compatible device. What is the difference between an “App” and a “Suite”? “Apps” are single applications running on the device used to collect and store data. In most cases, multiple apps would be utilized to handle various operations. For example, the ‘Item_Quantity’ app is one of the most widely used apps and the most direct means to take a basic inventory count, it produces a data file showing what items are in stock, the relative quantities, and requires minimal input from the mobile worker(s). Other operations will require additional input, for example, if you also need to know the specific location for each item in inventory, the ‘Item_Lot_Quantity’ app would be a better fit. Apps can be used in a variety of ways and provide the LDX10 the flexibility to handle virtually any data collection operation. “Suite” files are simply collections of individual apps. Suite files allow you to easily manage and edit multiple apps from within a single ‘store-house’ file and provide an effortless means for device deployment. -

The Ifplatform Package
The ifplatform package Original code by Johannes Große Package by Will Robertson http://github.com/wspr/ifplatform v0.4a∗ 2017/10/13 1 Main features and usage This package provides the three following conditionals to test which operating system is being used to run TEX: \ifwindows \iflinux \ifmacosx \ifcygwin If you only wish to detect \ifwindows, then it does not matter how you load this package. Note then that use of (Linux or Mac OS X or Cygwin) can then be detected with \ifwindows\else. If you also wish to determine the difference between which Unix-variant you are using (i.e., also detect \iflinux, \ifmacosx, and \ifcygwin) then shell escape must be enabled. This is achieved by using the -shell-escape command line option when executing LATEX. If shell escape is not enabled, \iflinux, \ifmacosx, and \ifcygwin will all return false. A warning will be printed in the console output to remind you in this case. ∗Thanks to Ken Brown, Joseph Wright, Zebb Prime, and others for testing this package. 1 2 Auxiliary features \ifshellescape is provided as a conditional to test whether shell escape is active or not. (Note: new versions of pdfTEX allow you to query shell escape with \ifnum\pdfshellescape>0 , and the pdftexcmds package provides the wrapper \pdf@shellescape which works with X TE EX, pdfTEX, and LuaTEX.) Also, the \platformname command is defined to expand to a macro that represents the operating system. Default definitions are (respectively): \windowsname ! ‘Windows’ \notwindowsname ! ‘*NIX’ (when shell escape is disabled) \linuxname ! ‘Linux’ \macosxname ! ‘Mac OS X’ \cygwinname ! ‘Cygwin’ \unknownplatform ! whatever is returned by uname E.g., if \ifwindows is true then \platformname expands to \windowsname, which expands to ‘Windows’. -

Getty Scholars' Workspace™ INSTALLATION INSTRUCTIONS
Getty Scholars’ Workspace™ INSTALLATION INSTRUCTIONS This document outlines methods to run the application locally on your personal computer or to do a full installation on a web server. Test Drive with Docker Getty Scholars' Workspace is a multi-tenant web application, so it is intended to be run on a web server. However, if you'd like to run it on your personal computer just to give it a test drive, you can use Docker to create a virtual server environment and run the Workspace locally. Follow the steps below to give it a spin. Scroll further for real deployment instructions. 1. Install Docker on your machine. Follow instructions on the Docker website: https://www.docker.com/ 2. If you are using Docker Machine (Mac or Windows), be sure to start it by using the Docker Quickstart Terminal. Docker is configured to use the default machine with IP 192.168.99.100. 3. At the command line, pull the Getty Scholars' Workspace image. $ docker pull thegetty/scholarsworkspace 4. Run the container. $ docker run -d -p 8080:80 --name=wkspc thegetty/scholarsworkspace supervisord -n 5. Point your browser to `<ip address>:8080/GettyScholarsWorkspace`. Use the IP address noted in Step 2. 6. The Drupal administrator login is `scholar` and the password is `workspace`. Be sure to change these in the Drupal admin interface. 7. To shut it down, stop the container: $ docker stop wkspc Web Server Installation These installation instructions assume you are installing Getty Scholars' Workspace on a server (virtual or physical) with a clean new instance of Ubuntu 14.04 as the operating system. -
