Querying Coherence Cache from JRuby

To complete the Coherence/JRuby demos this final demo shows how we can query the cache using filters to show the data we are interested in. From this demo you can see our cache has the oracle data dictionary view ALL_DB_OBJECTS data which was loaded from an 11.2.0.2 RDBMS. The output will make that obvious.

JRuby script is as follows - coh-extend-client-query.rb

require 'java'
require 'C:/jdev/scripting/demos/jruby/extendclient-coherence/extenddemo.jar'
require 'C:/jdev/coherence/36/coherence/lib/coherence.jar'

include_class "pas.au.coherence.extend.server.AllDBObject"
import com.tangosol.net.CacheFactory
import com.tangosol.net.NamedCache
import java.util.Date
import java.lang.System
import java.math.BigDecimal
import java.util.Set

puts "***********************************************"
puts "Coherence 3.6 Extend Client Example from JRUBY"
puts "***********************************************"

print "Started at ", Date.new.toString, "\n"

begin

  # setup required properties to connect to proxy server as extend client
  System.setProperty("tangosol.pof.enabled", "true")
  System.setProperty("tangosol.pof.config", "extend-pof-config.xml")
  System.setProperty("tangosol.coherence.cacheconfig", "client-cache-config.xml")
  System.setProperty("proxy.host", "papicell-au2.au.oracle.com")

  # get named cache alldbobjs
  alldbobjs = CacheFactory.getCache("alldbobjs")

  #retrieve size of cache
  print "\nCache [alldbobjs] size  = " + alldbobjs.size().to_s + "\n\n"
  
  #retrieve all SCOTT schema entries
  filter = com.tangosol.util.filter.EqualsFilter.new("getOwner", "SCOTT")
  scottObjects = alldbobjs.entrySet(filter)
  
  #iterate through SCOTT's objects 
  print "\nTotal of " + scottObjects.size().to_s + " cache entries found \n"

  print "Is scottObjects empty : ", scottObjects.empty?, "\n"
  puts
  
  iterator = scottObjects.iterator()
  while iterator.hasNext()
    entry = iterator.next()
    print "Key : [" + entry.getKey().to_s + "] "
    print "Value : [Owner=" + entry.getValue().getOwner() + 
          ", objectName=" + entry.getValue().getObjectName() +
          ", objectType=" + entry.getValue().getObjectType() + "]"
    puts
  end
  
rescue 
  print "\n** Error occured **\n"
 print "Failed to access Coherence Cluster from proxy server -> \n", $!, "\n\n"
  
end

puts
print "Ended at ", Date.new.toString, "\n"

The output when run shows the SCOTT schema objects being queried from the cache

Access Coherence Cache from JRuby as an Extend client

In my previous example below I wanted to quickly join a coherence cluster from JRuby and basically did it the easiest way possible by simply becoming a member in the cluster.

Access Coherence Cache from JRuby/Jython scripts

In the example below we will we use JRuby as a Coherence*Extend client using POF (Portable Object Format) and we do this for the following reasons.

1. Being a console application we want to connect/disconnect many times a day and even though we are a storage disabled member it results in overhead which an extend client avoids.
2. Being an extend client we are storage disabled by default.
3. Using POF has many advantages ranging from performance benefits to language independence, although in this example we are using it from a Java enabled client.

So our JRuby code is now as follows.

require 'java'
require 'C:/jdev/scripting/demos/jruby/extendclient-coherence/extenddemo.jar'
require 'C:/jdev/coherence/36/coherence/lib/coherence.jar'

include_class "pas.au.coherence.extend.server.AllDBObject"
import com.tangosol.net.CacheFactory
import com.tangosol.net.NamedCache
import java.util.Date
import java.lang.System
import java.math.BigDecimal

puts "***********************************************"
puts "Coherence 3.6 Extend Client Example from JRUBY"
puts "***********************************************"

print "Started at ", Date.new.toString, "\n"

begin

  # setup required properties to connect to proxy server as extend client
  System.setProperty("tangosol.coherence.cacheconfig", "client-cache-config.xml")
  System.setProperty("tangosol.pof.enabled", "true")
  System.setProperty("tangosol.pof.config", "extend-pof-config.xml")
  System.setProperty("proxy.host", "papicell-au2.au.oracle.com")

  # get named cache alldbobjs
  alldbobjs = CacheFactory.getCache("alldbobjs")

  #retrieve size of cache
  print "\nCache [alldbobjs] size  = " + alldbobjs.size().to_s + "\n\n"

  #retrieve one record
  objectid = BigDecimal.new(54)

  objectrecord = AllDBObject.new
  objectrecord = alldbobjs.get(objectid)

  puts "Record 54 = " + objectrecord.to_s
  puts

rescue
  print "\n** Error occured **\n"
        print "Failed to access Coherence Cluster from proxy server ", $!, "\n\n"

end

print "Ended at ", Date.new.toString, "\n"

From the code we have done the following.

1. Used a client cache config file to connect as an extend client, basically connect to an extend proxy which is a cluster member.

2. We provide a client JAR file which contains our domain objects and config files that being extenddemo.jar

3. The client cache config is defined as follows.

<!DOCTYPE cache-config SYSTEM "cache-config.dtd">

<cache-config>
  <caching-scheme-mapping>
    <cache-mapping>
      <cache-name>alldbobjs</cache-name>
      <scheme-name>remote</scheme-name>
    </cache-mapping>
  </caching-scheme-mapping>
  <caching-schemes>
    <remote-cache-scheme>
      <scheme-name>remote</scheme-name>
      <initiator-config>
        <tcp-initiator>
          <remote-addresses>
            <socket-address>
              <address system-property="proxy.host">
  papicell-au2.au.oracle.com
       </address>
              <port system-property="proxy.port">
                9099
              </port>
              <reusable>true</reusable>
            </socket-address>
          </remote-addresses>
        </tcp-initiator>
      </initiator-config>
    </remote-cache-scheme>
  </caching-schemes>
</cache-config>

So when we run this we get output as follows.

Access Coherence Cache from JRuby/Jython scripts

The following example show how to use JRuby or Jython to access Coherence caches. Although this is basic and simply using the cache config file out of coherence.jar it gives you enough to see how simple it is to join the cluster as member and access coherence.jar from these 2 scripting languages.

I could of easily used groovy here as well but decided to stick with jruby and jython for now. Also the script members that join the cluster are storage disabled meaning that they must connect to node which is storage enabled to add data to the cache.

For this demo I have the following installed.

• Coherence 3.6
• JDK 1.6
• JRuby 1.5.6
• Jython 2.5.1

PRE STEPS

1. Start a cache server as follows. We do this to ensure we have a storage enabled node. The cache config file being used is the one inside coherence.jar. 

C:\jdev\coherence\36\coherence\bin>cache-server.cmd

In the example below jy = jython and jrb = jruby executables.

JRUBY

1. Create a ruby script as follows.

require 'java'
require 'C:/jdev/coherence/36/coherence/lib/coherence.jar'

import com.tangosol.net.CacheFactory
import com.tangosol.net.NamedCache
import java.util.Date
import java.lang.System

puts "*********************************"
puts "Coherence 3.6 Example from JRUBY"
puts "*********************************"

print "Started at ", Date.new.toString, "\n"

begin

  # ensure we are storage disabled
  System.setProperty("tangosol.coherence.distributed.localstorage", "false")
  
  CacheFactory.ensureCluster

  # get named cache
  testcache = CacheFactory.getCache("Test")

  # add data to cache
  testcache.put("1", "pas apicella")

  # retrive data from cache
  puts "Cache entry 1 = " + testcache.get("1")
  
rescue 
 print "Failed to access Coherence Cluster ", $!, "\n"
 
ensure 
  CacheFactory.shutdown
  
end

print "Ended at ", Date.new.toString, "\n"

2. Run it as follows ensuring your reference coherence.jar correctly

> jrb coherence.rb

Output as follows

1. Create a jython script as follows

from com.tangosol.net import CacheFactory, NamedCache
from java.util import Date
from java.lang import System as javasystem

print "*********************************"
print "Coherence 3.6 Example from JYTHON"
print "*********************************"

print "Started at " + Date().toString()

try:

 javasystem.setProperty("tangosol.coherence.distributed.localstorage", "false")
  
 CacheFactory.ensureCluster()
 
 # get named cache
 testcache = CacheFactory.getCache("Test")
 
 # add data to cache
 testcache.put("1", "pas apicella")

 # retrive data from cache
 print "Cache entry 1 = " + testcache.get("1")

except:
    print "Unexpected error:", sys.exc_info()[0]
    raise
    
finally:
    CacheFactory.shutdown()
    
print "Ended at " + Date().toString()
    
    

2. Add coherence.jar to the classpath as shown below.

> set CLASSPATH=C:\jdev\coherence\36\coherence\lib\coherence.jar

3. Run it as follows ensuring your reference coherence.jar correctly

> jy coherence.py

Output as follows
