Oracle DB Query (Number)

The Oracle DB Query (Number) service runs user-specified queries to return specified columns as numeric representations.

SolarWinds MSP recommends that you use a user name with View-Only privileges when configuring the service.

The Library used is the native Oracle library. There is no extra configuration required on the client or server side as long as the listener has been correctly configured.

Helper tool (DatabaseInvoker.exe)

To check the connectivity or query results for the Oracle server from a monitored device, run the DatabaseInvoker.exe located in the Probe or Agent bin folder. For more data, open the outfile.txt (located in the same folder) to find the column name and check values before configuring service details.

Service Status

Service Type


Instances on a Device


Supported Systems/Applications

Oracle DB server 10.2 or higher

Device Class

Server - Generic and Server - Windows

Monitored By

Windows Agent or Windows Probe

Note: If a device has an Agent installed and the service is added, only the Agent performs the monitoring. An Agent can be used to monitor a remote Oracle server if the IP/Hostname is set in the Service Details.

Scan Interval

15 minutes

Connection Timeout Value

Time (in seconds) the Agent or Probe will wait for a connection response from an Oracle server before timing out.

This value is used the in Connection String in place of [CONNECT_TIME_OUT_VALUE].

Query Timeout Value

Time (in seconds) the Agent or Probe will wait for a query response to return from an Oracle server before timing out.

Hostname or IP address

Hostname or IP address of the Oracle listener.

This value is used in the Connection String in place of [HOSTNAME_VALUE].

Instance Port

Port number of the Oracle listener.

This value is used in the Connection String in place of [PORT_VALUE].


SERVICE_NAME set up in listener.ora. Using SID, change the connection string accordingly.

This value is used in the Connection String in place of [SERVICE_NAME_VALUE].

Server Type

Oracle server type, dedicated, shared, etc.

This value is used in the Connection String in place of [SERVER_TYPE_VALUE].

Connection String

Enter the connection string in the Connection String field under Service Details or have the Agent or Probe assemble the connection string by replacing the value provided in the service details. Note: If you enter the complete connection string, the password will appear in plain text and is visible.

The default connection string is set in TNS format. To connect using EZ connection, use the following format:


The Agent or Probe replaces the entities enclosed in brackets in the connection string with the value inputted in Service Details. This enables you to change the connection string as required.

Database Username

Username used to access the instance.

This value is used in the Connection String in place of [USERNAME_VALUE].

Database Password

Password used to access the database.

This value is used in the Connection String in place of [USERNAME_VALUE].

Database Query

SQL query statement submitted to the database. As a best practice, specify the column name in the query and avoid using “*?.

Numeric Column Name

Specify a column name that represent a numeric values. The column name could be the table column name or the name specified as "AS." If the Column Name is incorrect, the service will indicate Failed.

Column 1-5 Name

  • Name of the database values being queried for the value.
  • Values that N-central should look for in the results of the Oracle query.

Note: If there is more than one column and regex the result is AND operation. For example, if users have specified column 1 and regex 1 and column 2 and regex 2, both conditions should return "True"for the service to indicate normal status.

Oracle DB Query (Number)

Transaction time in milliseconds

Time to connect, authenticate, send a query, retrieve results, and disconnect.

Total Number Of Rows returned by The Query

Number of rows returned by a query.

Rows returned by the query that matched all column regular expressions

The number of rows that matched all of the column regular expressions.
