Process handlers prevent the creation of duplicate CIs by filtering out parameters
known to have inconsistent values before process classification occurs. You can create new
classifiers or edit existing ones.

## Before you begin

Role required: none

## Procedure

1. Navigate to AllDiscovery DefinitionCI ClassificationProcess Handlers.
2. Click New.
3. Complete the fields on the Process Handler form.  
   {#t_CreateAProcessHandler__table_egg_1wv_1q__entry__2}{#t_CreateAProcessHandler__ph_entry-name}{#t_CreateAProcessHandler__ph_entry-active}{#t_CreateAProcessHandler__ph_entry-condition}{#t_CreateAProcessHandler__ph_Script1}

   | Field | Description |
   |-|-|
   | Name | Enter a unique name for the process handler record. |
   | Active | Select the check box to run the process handler. |
   | Classify | * Select the check box to enable classification of any Running Process \[cmdb_running_process\] record that matches this Process Handler's conditions. * Clear the checkbox to disable classification of any Running Process \[cmdb_running_process\] record that matches this Process Handler's conditions. {#t_CreateAProcessHandler__ul_wc1_fwv_1q} |
   | Condition | Select the conditions that trigger the process handler to run the script. In most cases, this condition contains either specific executable names or the presence of certain parameters. |
   | Script | Enter the JavaScript you want to run on the current record in the Running Process \[cmdb_running_process\] table when the Condition is met. The `current` variable is a reference to a Running Process GlideRecord. The script should examine `current.parameters` for certain values, perform string replacement to manipulate these values, and save the result to `current.key_parameters`. ServiceNow uses the key_parameters field, together with the process name, to determine whether the process is unique on a specific machine.{#t_CreateAProcessHandler__p_Script2} See [On classification script objects for Discovery](https://servicenow-prod.fluidtopics.net/IKmMX1oJVjWuzD0~ta_9aQ "Use an On classification script in a process classifier to customize an application record.") for additional options. |
   [Table 1. Process Handler form]

4. Click Submit.

## What to do next

Run a discovery through the [Discovery
Schedule](https://servicenow-prod.fluidtopics.net/CIQEq9XeYjrEAd3sKWHEVg "A discovery schedule determines what horizontal discovery searches for, when it runs, and which MID Servers are used. Create a discovery schedule for your local environment or a schedule for discovering the resources in your cloud service account.") to search for applications and then [verify the results in the CMDB](https://servicenow-prod.fluidtopics.net/qeyh~9Q9YnmG7Rb~kqs44g "Discovery identifies several types of software.") for the applications that are found.
