Page 2Copyright © 2007 The Apache Software Foundation. All rights reserved.1 OverviewThis document covers the basics of running Solr using an example schema, and some sampledata.2 RequirementsTo follow along with this tutorial, you will need...1.Java 1.5 or greater. Some places you can get it are from Oracle, Open JDK, IBM, orRunning java -version at the command line should indicate a version numberstarting with 1.5. Gnu's GCJ is not supported and does not work with Solr.2.A Solr release.3 Getting StartedPlease run the browser showing this tutorial and the Solr server on the same machineso tutorial links will correctly point to your Solr server.Begin by unziping the Solr release and changing your working directory to be the"example" directory. (Note that the base directory name may vary with the version of Solrdownloaded.) For example, with a shell in UNIX, Cygwin, or MacOS:user:~solr$ lssolr-nightly.zipuser:~solr$ unzip -q solr-nightly.zipuser:~solr$ cd solr-nightly/example/Solr can run in any Java Servlet Container of your choice, but to simplify this tutorial, theexample index includes a small installation of Jetty.To launch Jetty with the Solr WAR, and the example configs, just run the start.jar ...user:~/solr/example$ java -jar start.jar2009-10-23 16:42:53.816::INFO: Logging to STDERR via org.mortbay.log.StdErrLog2009-10-23 16:42:53.907::INFO: jetty-6.1.26...Oct 23, 2009 4:41:56 PM org.apache.solr.core.SolrCore registerSearcherINFO: [] Registered new searcher Searcher@7c3885 mainThis will start up the Jetty application server on port 8983, and use your terminal to displaythe logging information from Solr.Solr tutorial

Page 3Copyright © 2007 The Apache Software Foundation. All rights reserved.You can see that the Solr is running by loading http://localhost:8983/solr/admin/ in your webbrowser. This is the main starting point for Administering Solr.4 Indexing DataYour Solr server is up and running, but it doesn't contain any data. You can modify a Solrindex by POSTing XML Documents containing instructions to add (or update) documents,delete documents, commit pending adds and deletes, and optimize your index.The exampledocs directory contains samples of the types of instructions Solr expects, aswell as a java utility for posting them from the command line (a post.sh shell script is alsoavailable, but for this tutorial we'll use the cross-platform Java client).To try this, open a new terminal window, enter the exampledocs directory, and run "java-jar post.jar" on some of the XML files in that directory, indicating the URL of theSolr server:user:~/solr/example/exampledocs$ java -jar post.jar solr.xml monitor.xmlSimplePostTool: version 1.2SimplePostTool: WARNING: Make sure your XML documents are encoded in UTF-8, other encodings are not currently supportedSimplePostTool: POSTing files to http://localhost:8983/solr/update..SimplePostTool: POSTing file solr.xmlSimplePostTool: POSTing file monitor.xmlSimplePostTool: COMMITting Solr index changes..You have now indexed two documents in Solr, and committed these changes. You can nowsearch for "solr" using the "Make a Query" interface on the Admin screen, and you shouldget one result. Clicking the "Search" button should take you to the following URL...http://localhost:8983/solr/select/?q=solr&start=0&rows=10&indent=onYou can index all of the sample data, using the following command (assuming yourcommand line shell supports the *.xml notation): user:~/solr/example/exampledocs$ java -jar post.jar *.xmlSimplePostTool: version 1.2SimplePostTool: WARNING: Make sure your XML documents are encoded in UTF-8, other encodings are not currently supportedSimplePostTool: POSTing files to http://localhost:8983/solr/update..SimplePostTool: POSTing file hd.xmlSimplePostTool: POSTing file ipod_other.xmlSimplePostTool: POSTing file ipod_video.xmlSimplePostTool: POSTing file mem.xmlSimplePostTool: POSTing file monitor.xmlSimplePostTool: POSTing file monitor2.xmlSimplePostTool: POSTing file mp500.xmlSimplePostTool: POSTing file sd500.xmlSimplePostTool: POSTing file solr.xmlSimplePostTool: POSTing file spellchecker.xml

Tutorial_4_solutions

1. For each of the following pairs of goods, which good would you expect to have more elastic

demand and why?

a. required textbooks or mystery novels

b. Beethoven recordings or classical music recordings in general

c. subway rides during the next 6 months or subway rides during the next 5 years

d. root beer or water

2. Suppose that business travellers and vacationers have the following demand for airline

tickets from New York to Boston:

Price Demand (business travellers) Demand (vacationers)

150 2,100 1,000

200 2,000 800

250 1,900 600

300 1,800 400

a. As the price of tickets rises from $200 to $250, what is the price elasticity of demand for (i)

business travellers and (ii) vacationers? (Use the midpoint method in your calculations.)

b. Why might vacationers have a different elasticity from business travellers?

Multi-Stage Rapid Drawdown 17-1

Slide v.6.0 Tutorial Manual

Multi-Stage Rapid Drawdown

When the water level at a dam drops, the stabilizing force due to the

weight of the water is removed. If the dam material has a low

permeability and the water level drops quickly, then excess pore

pressures will be slow to dissipate. This causes reduced stability in the

slope. This tutorial describes how to use Slide to model rapid drawdown

and examine the effect on dam stability and factor of safety.

The finished product of this tutorial can be found in the Tutorial 17

Rapid Drawdown.slim data file. All tutorial files installed with Slide

6.0 can be accessed by selecting File > Recent Folders > Tutorials Folder

from the Slide main menu. Topics Covered

• Rapid Drawdown: Duncan, Wright and Wong

• Rapid Drawdown: Lowe and Karafiath
