CAST-CED - Setting the maximum number of cached JDBC connections

To avoid a situation where the CAST Engineering Dashboard will display a blank page on login due to cached connections to the CAST Dashboard Service remaining open indefinitely, a parameter exists in the web.xml file that limits these cached JDBC connections. This parameter is set to 50 cached JDBC connections by default:

<context-param>
	<param-name>jdbc.connections.maximum</param-name>
	<param-value>50</param-value>
	<description>maximum number of cached jdbc connections</description>
</context-param>

• If the parameter is not present in the web.xml file, only 50 connections will be cached by the CAST Engineering Dashboard.
• This parameter may be set to 0, but this will result in each user action opening a new connection, which may reduce dashboard performance.
• It is recommended not to set it to a number below the number of concurrent users.
