    Create applicative credentials on the ServiceNow AI Platform. For more information, see [Applicative credentials](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-security/applicative-creds.md).

-   **Use Oracle Wallet authentication instead of applicative credentials**

    For more information, see [Oracle Wallet authentication for database discovery](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-operations-management/discovery-and-service-mapping-patterns/oracle-wallet-authentication.md).

-   **For virtual machines: Verify virtual machine credentials**

    For virtual machines, verify you have the relevant credentials to collect hardware data for machines hosted on the following virtual providers:

    -   VMware
    -   Nutanix
    -   IBM
    -   Hyper-V
-   **For virtual machines: Collect hardware data**

    To populate the CPUQ folder in your GLAS report download, run the Oracle-provided hardware script on each target virtual machine. The following table lists the required script and credentials for each operating system.

    |Operating system|Script|Required credentials|
    |----------------|------|--------------------|
    |Windows|cpuq.cmd|Username and password|
    |Linux or UNIX|cpuq.sh|Root username and password|

    Access to the operating system command line is required. Use **Command Prompt** on Windows systems and a UNIX Shell on Linux or UNIX systems.

    1.  Log in to the target virtual machine using the required credentials.
    2.  Open the command-line interface for the operating system.
    3.  Run the hardware script for the operating system.
    4.  Repeat for each target virtual machine.
-   **For large-scale or high-volume environments: You can enable Oracle GLAS V2 data collection**

    To use V2 database data collection instead of the default V1 method, set the **sn\_itom\_oracleglas.enable\_large\_env\_glas\_data\_collection** system property to **true**. For more information about V2, see the "Oracle GLAS Data Collection V2" section. For instructions, see [Enable the Oracle GLAS V2 data collection method](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-operations-management/discovery-and-service-mapping-patterns/enable-oracle-glas-v2-method.md).

## Oracle GLAS Data Collection V2

Oracle GLAS Data Collection V2 is an alternative database data collection method that uses the **Oracle GLAS Data Collection V2** pattern extension. V2 optimizes database data collection for large-scale or high-volume Oracle database environments. The V2 method applies to database data collection only; middleware and Java data collection aren't affected.

In V2, the MID Server collects data from the Oracle GLAS scripts and uses the GlideRecord API to populate the Oracle GLAS Database Audit Data \[sn\_itom\_oracleglas\_glas\_data\_for\_database\] table directly. As a result, GLAS data appears in the Content field and not in the discovery payload. To verify data population, navigate to the Oracle GLAS Database Audit Data table and review the **Content** field. If data is missing or incomplete, see [MID Server ECC Queue](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/servicenow-platform/ecc-queue-mid-server.md) for information about accessing MID Server logs.

V2 stores all database GLAS data in the Oracle GLAS Database Audit Data table. Each record directly references the Oracle Instance \[cmdb\_ci\_db\_ora\_instance\] table; in V1, this association is established through a CI relationship \(see the "V1 database CI relationships" section\).

The Oracle GLAS Data Collection V2 pattern extension populates the following fields in the Oracle GLAS Database Audit Data table:

<table id="table_glas_v2_fields"><thead><tr><th>

Field

</th><th>

Description

</th></tr></thead><tbody><tr><td>

Host Name \[hostname\]

</td><td>

Host name of the server running the Oracle instance.

</td></tr><tr><td>

DB Name \[dbname\]

</td><td>

Name of the Oracle database.

</td></tr><tr><td>

Type \[type\]

</td><td>

Identifies the type of GLAS data stored in the record. Possible values:-   ORCL\_OVERVIEW
-   ORCL\_DETAILS
-   ORCL\_LICENSE
-   ORCL\_SESSION
-   ORCL\_OPTIONS
-   ORCL\_DBA\_USERS

</td></tr><tr><td>

Order \[order\]

</td><td>

Sequential order of the record. If the content for a type exceeds 10 megabytes \(MB\), it is stored in multiple records ordered sequentially starting from 0.

</td></tr><tr><td>

Content \[content\]

</td><td>

Collected GLAS data for the record type. Maximum size is 10 MB per record.

</td></tr><tr><td>

Oracle Instance \[oracle\_instance\]

</td><td>

References the Oracle Instance \[cmdb\_ci\_db\_ora\_instance\] table.

</td></tr></tbody>
</table>When V2 is enabled, the navigation menu updates automatically, hiding the six V1 database modules and displaying the **GLAS V2 - Databases** module.

## Properties installed with the Middleware data collection application

To access the installed application properties, navigate to **All** &gt; **System Properties** &gt; **All Properties**. You must have the admin role to modify these properties.

|System property|Default value|Description|
|---------------|-------------|-----------|
|**sn\_itom\_oracleglas.isMaskingIp**|true|Determines whether to mask the IP Address in Oracle middleware tracked files by replacing the value with "text\_removed."|
|**sn\_itom\_oracleglas.isMaskingUserName**|true|Determines whether to mask the user name in Oracle middleware tracked files by replacing the value with "text\_removed."|
|**sn\_itom\_oracleglas.isMaskingPort**|true|Determines whether to mask the port in Oracle middleware tracked files by replacing the value with "text\_removed."|

## Control GLAS data collection

The following MID Server property controls the GLAS data collection: **sn\_itom\_oracleglas.disable\_glas\_data\_collection**

The property is set to **False** by default.

**Note:** In Data Collection for Oracle Global Licensing and Advisory Services versions earlier than 1.10.2, the property name is **sn\_itom\_pattern.disable\_glas\_data\_collection**.

## Oracle Java process discovery

ITOM Visibility can discover Java-running processes in your infrastructure, allowing you to comply with Oracle licensing agreements and prepare for GLAS Audits. You can perform the discovery using the Java Installation pattern \(IP-based\), Agent Client Collector with application patterns, or Agent Client Collector with file-based discovery.

In the pattern flow, the Java processes are discovered by Application Dependency Mapping \(ADM\). When the processes are discovered, the Java Installation pattern triggers and collects the data.

For information about privileged user access, see [KB1705845](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1705845).

For more information about Agent Client Collector with patterns, see [Application patterns for the Agent Client Collector](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-operations-management/agent-client-collector/application-patterns-acc.md).
