/* -------------- CUSTOM LOGIC ----------------------*/

Customizing existing rules

The advantage of providing a rules based allocation fitting process is that you can customize the

existing rules to change the business logic by modifying the CUSTOM LOGIC portion of the code.

You can modify or delete existing rules, or add new custom rules. Rules are written in Java and

the Drools syntax.

Available hooks for customizing:

• SubnetPolicyCheck.applyFitting

• AttributeBasedSubnetPolicyCheck.applyFitting

• SpecifiedSubnetPolicyCheck.applyFitting

• AutomaticIpAddressPolicyCheck.applyFitting

• StaticIpAddressPolicyCheck.applyFitting

• DhcpIpAddressPolicyCheck.applyFitting

• PhysicalServerPolicyCheck.applyFitting

• PhysicalBootDiskPolicyCheck.applyFitting

• NPIVDataDiskPolicyCheck.applyFitting

• VirtualServerPolicyCheck.applyFitting

• EsxDiskPolicyCheck.applyFitting

• HypervDiskPolicyCheck.applyFitting

• DasDiskPolicyCheck.applyFitting

• SoftwarePolicyCheck.applyFitting

Writing a new rule file

Open a new drl file in a text editor, add the different sections of a rule file (as shown in “Rule

file”), and add the new rule logic.

• Package—The name of the package and is always com.hp.hpio.controller.policy.

• Import—Declares the use of any other Java classes required to write the rule business logic.

• Rules:

— You can define multiple rules in a single rule (.drl) file.

— Each rule contains the business logic that you would like to execute in your rule.

— The INIT rule is a sample structure that you can duplicate and use as a starting point

to define your own rule.

You can also use tools such as Eclipse (http://downloads.jboss.com/drools/updatesite3.3/) to

write rule files by including the Drools Eclipse plug-in to the create rule project and including

the required Insight Orchestration libraries to the project. Using Eclipse helps with syntax

highlighting and auto code completion.

For more information, see the following documentation:

• JBoss Rules User Guide at http://downloads.jboss.com/drools/docs/4.0.7.19894.GA/

html_single/index.html

• JBoss Rules at http://downloads.jboss.com/drools/docs/4.0.7.19894.GA/apidocs/index.html

Example: Custom rule

rule "CustomRule1"

when

$pVO : PolicyExecutionVO( );

$resLst : List();

/* --------------- CUSTOM LOGIC ------------------ */

// Get service entity and resource objects.

$logicalSubnet : LogicalSubnet();
