Oracle GLAS data collection using patterns

The ServiceNow Discovery application uses the Oracle GLAS Data Collection pattern extensions to discover Oracle GLAS data. This data includes discovered Oracle Database, Middleware, and Java configuration items.

Oracle GLAS Data Collection patterns are extensions of the following patterns:

• Oracle Database on UNIX and Windows patterns
• Oracle Middleware on Linux for the following patterns:
  • Oracle Tuxedo
  • WebLogic
  • Linux
• Oracle Java on Java installation pattern

The Oracle Database and Middleware patterns execute the pattern extensions, and the data collected is stored in the ServiceNow tables for GLAS data.

For details on how to view and download the collected Oracle GLAS data, see Download Oracle Global License Advisory Services (GLAS) data.

To learn about the supported versions of Oracle, refer to Detailed information on products discovered by ITOM Visibility.

The Data Collection for Oracle Global Licensing and Advisory Services application supports two database data collection methods. The default method, V1, stores data across six CMDB CI tables. V2, available starting with Data Collection for Oracle Global Licensing and Advisory Services version 1.12.0, is an alternative method optimized for large-scale or high-volume Oracle database environments that consolidates data into a single non-CMDB table. For more information about V2, see the "Oracle GLAS Data Collection V2" section.

Prerequisites

• Install the Data Collection for Oracle Global Licensing and Advisory Services store app

  Navigate to System Definition > Plugins and install the Data Collection for Oracle Global Licensing and Advisory Services app.

  • The minimum version for Database collection is 1.4.0
  • The minimum version for Middleware collection is 1.7.1
  • The minimum version for Java collection is 1.8.4 Note: The Data Collection for Oracle Global Licensing and Advisory Services app requires the Discovery (com.snc.discovery) plugin to work correctly.

• Verify the following applications are installed

  • Discovery and Service Mapping Patterns
  • CMDB CI Class Models

• Verify operating system privileges

  Verify that your Windows or UNIX user can write temporary files under /tmp.

  Verify that you can run the following operating system commands:

  • ls
  • cat
  • ps
  • Create operating system credentials

  Verify that you have the following credentials for your operating system, and then create credentials for them on the ServiceNow AI Platform:

  • UNIX credentials using SSH. For more information, see SSH credentials.

  • Windows credentials using PowerShell/WMI. For more information, see Windows credentials.

    Note: PowerShell and WMI credentials are required only for Database collection.

• Verify the following Oracle privileges

  Verify that you have applicative credentials for the Oracle instance (cmdb_ci_db_ora_instance) that have the following privileges:

  • Read permissions on the tnsnames.ora file.
  • Permissions to execute the sqlplus command.
  • (For middleware collection) Sudo permissions to run the following command: sudo su - oracle -c "$ORACLE_INSTANCE/bin/opmnctl status" Verify you have the user name and password for the relevant Oracle Database, with read permissions on the following tables.

• Create applicative credentials for Oracle Instance

  Create applicative credentials on the ServiceNow AI Platform. For more information, see Applicative credentials.

• For UNIX: You can use Oracle Wallet authentication instead of applicative credentials

  For more information, see Enable Oracle Wallet authentication for discovery.

• 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.
  5. 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_pattern.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.

V1 database CI relationships

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 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:

When V2 is enabled, the navigation menu updates automatically, hiding the six V1 database modules and displaying the GLAS V2 - Databases module. To enable V2 data collection, see Enable the Oracle GLAS V2 data collection method.

Tuxedo middleware extension

Tuxedo license configuration and log files collected:

• *_InstallLog.log

Middleware CI relationships

These relationships are created by a containment rule that describes the valid objects that the Linux CIs can contain.

Properties installed with the Middleware data collection application

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

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.

For more information about Agent Client Collector with patterns, see Application patterns for the Agent Client Collector.

For more information about Agent Client Collector with file-based discovery, see Discover java installation data using Agent Client Collector for Visibility Content file-based discovery.
