BE Cache Usage Overview

Created on: Jul 14, 2008 1:30 PM

Created by: puneet arora

BE 2.x and 3.x are fully integrated with Coherence Cache as the Object Management Layer. What does this mean?

BE in contrast to orchestration engines is a stateful engine. The state is defined as the collection of instances of concepts, scorecards and events at any point in time. These instances are maintained within BE untill they are explicitly retracted using deleteInstance or consumeEvent in case of an event. The other mechanism for removing events from the state are using Time To Live (TTL). The events are automatically retracted from the state once the Time To Live expires. Given that, there are multiple considerations while designing a model to take advantage of the state management.

State Capsules

---------------------

1. RETE Working Memory

Once an object is asserted to BE using assertEvent() or createInstance(), the RETE network remembers the past matches. For example, if there's a rule of the form . The RETE network internally maintains join tables that in this case would store all asserted orders in this join table (Note that the objects are not stored within the engine but a virtual object reference is maintained in the RETE network). There is one setting that influences this behavior:

In the Object Management tab in the deployment, there are various settings for each concept/ scorecard/ event type:

1. CACHE+WM

2. CACHE ONLY

3. Memory Only

The CACHE+WM is the default option and in this case, BE does maintain the RETE network for the instances. There are various deployment strategies where this option may not work due to JVM heap size constraints coupled with GC times. In these cases, the fast responsiveness of the RETE network is offset by high memory usage thus resulting in poor performance. In those cases, it is recommended to use CACHE ONLY for the instances that change often and the system is required to hold large amount of state. In CACHE ONLY, the system does not store pre-matched join tables for the rules. The logic changes as follows:

1. On an Event X, use C_Load... calls to load the instances that might be affected by this event.

2. Distributed Cache

The Partitioned/ Distributed Cache is the only logical topological choice as the backing map for all instances. It is recommended that the BE engines are run with localstorage off and the data is solely stored in cache server nodes. Each cache server node should ideally be not sized more than 1 GB. I'll post a separate thread on multi data center topology.

3. Oracle Backing Store

This layer is optional and is used to replicate all instances to an Oracle store. The oracle schemas take advantage of Oracle Object Types thus bypassing the costs of an Object Relational Mapping tools such as Hibernate. A separate thread on this as well.

More to follow.....

Re: BE Cache Usage Overview

Hi Puneet

I would like to understand better the join table usage.

In an configuration based on separate engines which engine is maintaining it ?

What about the references to the objets maintained by the RETE network ? Is their number proportional to the rules and conditions refencing them ?

Re: BE Cache Usage Overview

Great question !!! There is no logical way to distribute a RETE network in an efficient manner. Thus in BE 3.x, the concepts are shared and thus available for inferencing and load in all the engines. The events are localized to one engine. This creates a framework where the rules have to be carefully designed to self-regulate their firing: For instance, if you have a rule

Scope: Order O

Condition: O.amt > 3000.00

Action: Do something

This rule will fire in all the agents| engines. In order to take advantage of the heterogenous nature of the network, the design of the rulebases should be built as

a) Option A: Scope : Order O

Event E

O.amt > 3000.00

Action: Do Something

b) Option B: Scope

Order O

Condition: O.amt > 3000.000;

O.s=false;

Action: O.s=true;

Do Something..

Internally, all object creations and modifications along with the bitmap (changed properties) are distributed to all the agents in a cluster. These notifications will result in rule firings not dissimilar to new events arriving into the system. If you follow these guidelines, you can create a highly scalable and distributed RETE network. Also, remember the Option B can be achieved by using state models since internally the state variable prevents the rule to fire in multiple engines.

Re: BE Cache Usage Overview

HI Punit,

can u provide me the configuration i need to do for backing-store implementaion.

I went thru the pdfs, but i was getting some error.

i have attched the error stack for reference.

Re: BE Cache Usage Overview

Fred, I see a NoClassDeffound error in the log. Make sure that the ojdbc14.jar that has the oracle drivers for DB connectivity are in your Classpath.

thanks

Re: BE Cache Usage Overview

Look on your machine for ojdbc14.jar. Its usually in your Oracle install lib folder. Mine is located at C:\oracle\ora92\jdbc\lib

Add that path to the TRA classpath. You could append it to tibco.env.STD_EXT_CP or CUSTOM_EXT_PREPEND_CP in all TRA's (cache servers and inference engines)

thanks

For your JDBC shared resource, Change your driver type to oracle:thin instead of the Tibco oracle driver.

Hi Robin,

Now i am successfully able to run the engine in cache -server mode with backing store.

But when i am trying to run another instance with infrence mode: its showing me the following error.

Make sure, that the engine and cache server tra's have the exact same cluster properties.

If you get any more errors, you might be better off posting a new conversation with an appropriate subject.

Hi Robin,

in fact i did that, but i didn't get reply.

Thats why i thought i 'ld get reply in this manner.

Anyway, i checked the cluster properties of both the TRAs.

Its infact same and still i am getting the following error.
