This describes the discovery and monitoring setup for the Oracle database.

Prerequisites

  • Database and port(1521) can be accessed by the gateway.
  • A gateway management profile mapped to a resource.
  • Create credentials with type Database before assigning a template to a resource. The Port, Connection Time-out, and Is Secure values are not used to create credentials.

Database Discovery and Monitoring

The administrator can deploy an agent or gateway to support OracleDB agent-based or agentless monitoring.

Discovery using the gateway

The gateway establishes a connection to the database using the Java Database Connectivity (JDBC) Java API and collects metrics using SQL queries. To monitor an OracleDB, install gateway version 5.0.0 or later.

Use one of the following mechanisms to discover OracleDB servers to add them to your inventory:

  • WMI
  • SSH
  • SNMP

Optionally, add a database server manually to the infrastructure inventory:

  1. Select Infrastructure and click Resources.
  2. Click the Settings icon on the top-right and click Add.
  3. On the Add Device page, enter the Device Type and any other information you want to enter.
  4. Click Save.

Prepare the device to start monitoring

  1. Associate appropriate database credentials to the discovered database.
  2. Assign one or more database-specific global monitors or templates on the device.
    Optionally, create custom metrics or monitors using SQL queries and assign them to the database.

To track monitoring of OracleDB database in your cloud environment, see Monitoring Cloud Database using Gateway.

Create custom metrics

To create a metric using SQL query for OracleDB monitoring, navigate to Monitoring > Metrics > Create Metric. For example, to create a metric to check the DB instance use:

SELECT INSTANCE_NAME, DATABASE_STATUS FROM V$INSTANCE

For more information, see Create a Metric.

Note: When creating a custom metric using SQL query, do not add or append semicolon(; ) at the end of the query.

Assign templates from setup

Assign OracleDB templates to one or more resources for a selected client and change the configuration parameters while assigning templates. For more information, see Assign Templates from Setup.

Assign templates at the device level

Applying Oracle templates at the device level helps assign one or more templates to a specific resource. You can change the configuration parameter default values while assigning the templates. For more information, see Assign Templates at the Device Level.

Template configuration parameters:

Configuration ParameterDescription
Connection Time-outThe maximum time to connect to the database. The driver waits for the specified time before timing out due to connection failure. The default time is 15000 milliseconds(ms).
Service Transport TypeTo configure the database at a secure end-point. The default type is In-secure. The connection is Secure when the data sent between the client and server is encrypted.
Service PortThe port number where the database is running. The connection is made to the specified port if you specify the port and the database name. The default port is 1521.
DB Instance NameThe name of the database to connect to. The default name is root.
  • If you have multiple instances with different ports, use the following syntax:

    Instance1:Port1,Instance2:Port2

    Note: Do not consider the service port configuration value here.

  • If you have a single instance, use the following syntax:

    “Instance1”

    Note: Consider the port from the service port configuration for this case.

  • If you have multiple databases with the same port, use the following syntax:

    “Database1, Database2, Database3”

    Note: Consider the port from the service port configuration for this case.

Application TypeThe application type value to identify the adapter. For example, ORACLE_DB.
Warning: Do not change the default application type value.

Assign Template from Device Management Policies

Device management policies help manage resources. You can assign monitoring templates, knowledge base articles, and custom attributes using device management policies. The device management policy can be applied to one or a set of resources. For more information, see Create Policies.

View Resource Metrics

The gateway monitors the application using the assigned templates and displays the results in graphical format. To view resource metrics, click the database resource name > resource Details > Metrics.

OracleDB

Troubleshooting

If you have OracleDB monitoring issues, verify gateway, telnet, and database connectivity:

ping <IP Address>
telnet <IP Address> <Port>
gcli
db <Database Type> <IP Address> <User Name> <Password> <Port> <Database Name/instanceName> <Connect Timeout> <ReadTimeout> <Secure Flag> <Query>

Beginning with gateway version 5.3.0, use the following format for the laset, including the result-set:

db <Database Type> <IP Address> <User Name> <Password> <Port> <Database Name/instanceName> <Connect Timeout> <Read Timeout> <Secure Flag> <ResultSet?: Yes/No> <Query>

Note: If instance connection type is servicename, then instead of <Database Name/instanceName> mention as <instanceName>:servicename in the above query.
