Oracle DB Query (REGEX) service
The Oracle DB Query (REGEX) service monitors the results of an SQL query sent to an Oracle database. The data returned by the SQL query is then evaluated against the regular expressions specified in the service.
N-able 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.
To check the connectivity or query results for the Oracle server from a monitored device, run the helper tool,
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.
|Instances on a Device||200|
|Supported Systems/Applications||Oracle DB server 10.2 or higher|
|Device Class||Server - Generic and Server - Windows|
Windows agent or Windows probe
Note: If a device has an agent installed and the service is added, the monitoring is done by the agent only. 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
This value is used in the Connection String in place of [SERVICE_NAME_VALUE].
Oracle server type, dedicated, shared, etc.
This value is used in the Connection String in place of [SERVER_TYPE_VALUE].
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.
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 will replace the entities enclosed in brackets in the connection string with the value inputted in Service Details. This allows 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." This value will be threshold against you can set your threshold accordingly. If the Column Name is incorrect there service show as failed.|
|Column 1-5 Name|
(Optional) Specify the Column that you want to return as string presentation.
Values display in Scan Details and provide additional detail on other table columns. If you specify a column name that doesn’t exist, the service will display as Failed.
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.|
|Numeric Value Returned||Numeric value presentation of the Column name specified in Numeric Column Name (see above).|
|Column 1-5 Value||String representation of Column 1-5 value (see above).|
