• RainbowInstall

Setting up Eclipse

• Start eclipse in a new workspace
• Check out the following projects from svn://acme.able.cs.cmu.edu/rainbow in framework/trunk
  • core/*
  • deployment/*
  • eclipse/*
  • system/*
  • test/*
• Should compile automatically. Unknown extension point error in org.sa.rainbow.core/plugin.xml can be ignored

Packages

• common: The Interfaces defining the APIs, and some abstract implementations, and utility classes.
• communication: Defines the communication layer between the target system and Rainbow, i.e., essentially the translation layer. Think Gauge and Probe bus APIs + effectors. Queue and RMI are implemented, JMS has some permissions related issues, and so is not really implemented. Queue is used for single machine instantiation, RMI is used for multi-machine.
• core: implementation of Rainbow architecture layer; model manager, evaluator, am, and strategy executor. Also contains target system API to interact with target.
  • src-sim provides simulation environment for target system (so you don't need to run the real znn, for example).
  • stitch defines the library of operators accessible from stitch script. Confounds architecture operator and effector. Any operator or query that gets used by stitch is defined in here.
• lang: Stitch grammar, parser, evaluator code. Uses ANTLR, Stitch[L|P|T] (Lexer, Parser, Tree). Build by ant buildGrammar.xml
• stitch.editor: Eclipse editor for stitch, mostly written by Ali

• translator: Implementation for probes, gauges, effectors. Also, RainbowDelegate, which allows Rainbow to run distributed (each sub-machine has a RainbowDelegate running on it).

• feature: the rainbow feature

• update: The update site. Update site is http://acme.able.cs.cmu.edu/rainbow; on baobab at /home/apache/sites/rainbow. To build update, do the usual stuff in site.xml, and then check it in. IN /home/apache/sites/rainbow/update do

  svn update

  to update the update site.
• translator.contrib: engagement-specific probes, gauges, and effectors (currently for talkshoe and znews)
• config: All example engagements (talkshoe, znn, etc).
• deploy: Has all required jar files for rainbow; eclipse launch configuration files; deploy for preparing deployment packages for various parts of rainbow om multiple machines for engagements.
• test: Unit test files, and a playground
• sdk.template: The set-up for Rainbow SDK, which is a way to package this stuff to give to researchers to use.

Executing znn.com example, Simulation

• config/znews0
• From eclipse, run configuration oracle-znews0. This will terminate at 100s. The default (as defined in rainbow.properties of znews0) is oscillation, which reduces the fidelity, gets good service but under-utilized, then raises fidelity, gets bad service, reduce fidelity, etc.

Executing znn.com example, Single machine

• in deploy, run deploy.xml, refresh and look in build. Copy app.rainbow.master.zip somewhere.
• in cygwin, cd somewhere and unzip app.rainbow...

• Install software needed by Znn.com, following instructions on the Znn.com benchmark site

  • Configuring mysql
    • mysqladmin -u root -p create wiki_wwwp

    • mysql -u root -p wiki_wwwp < wiki_wwwp-dump.sql

    • Give user "wikiuser" access to the database, command and expected output shown below:

      mysql> create user wikiuser@localhost identified by '';
      Query OK, 0 rows affected (0.00 sec)
      mysql> grant select on wiki_wwwp.* to wikiuser@localhost;
      Query OK, 0 rows affected (0.00 sec)
