Configuring the SQL monitor adapter
Adapter type: ro-adapter-sql-monitor_vv.rr.nn
You can define the URL for an SQL query in the following ways:
Define the target, port, subprotocol, database, and any parameter as elements in the configuration, allowing the process to form the URL.
The following figure is an excerpt from the SQL actor adapter configuration that depicts method 1 of defining the URL. You need supporting elements to form the complete configuration.
XML sample of method 1 for defining a URL<host>host1</host>
<port>port1</port>
<subprotocol>oracle:thin</subprotocol>
<database>database1</database>Define the complete URL, including parameters, in a single element in the configuration.
The following figure is an excerpt from the SQL actor adapter configuration that depicts method 2 to define the URL. You need supporting elements to form the complete configuration.
XML sample of method 2 for defining a URL<url>jdbc:oracle:thin:@target1:port1:database1?param1=abc¶m2=xyz</url>
The following table describes the adapter configuration elements for the SQL monitor adapter.
SQL monitor adapter configuration node elements
Element | Description | Required |
<targets>|
Contains the <target> element
|
Yes
<target>|
Contains the SQL server, database, and connection information.
This element has a name attribute that provides a target name. If the target name has a default attribute with the value set to true, the target is a global target, else the target is a local target.
|
No
<url>|
Specifies the complete connection URL for the target database
If you do specify the <url> element, you must specify <host>, <port>, <subprotocol>, and <database> elements as needed so that the process can create the URL.
|
No
<host>|
Specifies the host name or the IP address of the database server
This element is required in the absence of the <url> element.
|
Conditional
<port>|
Specifies the port on which the database server listens
The requirements for the JDBC driver specified in the <driver> element determine whether the <port> element is required. This element is not used if you specify the <url> element.
|
Conditional
<user-name>|
Specifies the user name to be used for database authentication
The database requirements in the user's environment determine whether the <user-name> element is required.
|
Conditional
<password>|
Specifies the password that corresponds to the <user-name>
The database requirements in the user's environment determine whether the <password> element is required.
|
Conditional
<subprotocol>|
Specifies the driver specified subprotocol, used to build the connection URL
The adapter prepends jdbc: to the value provided. This element is required in the absence of the <url> element.
- Format: <database type>:<subprotocol>
- Sample values: sybase:Tds, oracle:thin
|
Conditional
<database>|
Specifies the name of the database to which the adapter connects This element is required in the absence of the <url> element.
|
Conditional
<driver>|
Specifies the fully qualified JDBC driver classname
The sample values are:
- com.sybase.jdbc3.jdbc.SybDriver
- oracle.jdbc.driver.OracleDriver
|
Yes
<character-set>|
Specifies the supporting CharSet
Also called character set, it includes identifiers describing a series of universal characters.
You must specify the <character-set> element only if the target database is MySql.
|

Default value: 120,000 milliseconds (2 minutes)
|
No
<evictor-idle-time-millis>|
Specifies the frequency, in milliseconds, in which a thread used to close idle connections runs

Encrypting an element's contents
You can add the attribute secure="true" to an XML adapter element XML view to ensure that the element's contents is encrypted when displayed.
Enabling custom logging
To enable custom logging for the adapter, you must specify a log file name. You can also provide additional parameters for logging.
- Log File Name: Provide a name for the log file.
This file will be stored in the AO_HOME/tomcat/logs directory. If Log File Max Backup Index value is greater than 0, the log file name is suffixed with the backup index. For example, if the parameter value is a.log, backup log files will have names, such as a.log.1, a.log.2. - Log File Size: Specify a size limit for the log file.
If the value specified for Log File Max Backup Index is greater than 0, when the specified size is reached, the current file is renamed with the suffix .1. Otherwise, the log file will be reset and over-written. The default value is 10MB. The available units are KiloBytes (KB), MegaBytes (MB) or GigaBytes (GB). - Log File Max Backup Index: Enter the maximum number of backup files allowed. The default value is 10.
- Log File Append: Select this option to append new log information to the existing information in the file. If unselected, the file will be overwritten with new log information.
Log Level: Enter the logging level using one of the following choices:
Logging level
Description
DEBUG
The most detailed logging level; logs low-level messages, normal execution, recoverable erroneous conditions, and unrecoverable erroneous conditions
INFO
(default)
Logs normal execution, recoverable erroneous conditions, and unrecoverable erroneous conditions
WARN
Logs recoverable erroneous conditions and unrecoverable erroneous conditions
ERROR
The least detailed logging level; logs only error conditions that are not usually recoverable
