A data source interceptor intercepts dynamic cluster scale up operations to validate that the scaling operation will not overload the database.
During dynamic cluster scale up operations, new dynamic server instances in a dynamic cluster are started. If data sources are targeted to the dynamic cluster, this may result in the creation of additional connections to the databases, which may result in exceeding database capacities. An interceptor intercepts a scaling action. A data source interceptor intercepts a dynamic cluster scale up operation to validate that the scaling operation will not overload the database.

The following table lists all of the data points that you can display in columns on this page.
Name Description Name
The alphanumeric name for this data source interceptor.
The regular expression for the connection URLs
The regex pattern for the connection URLs. The URL pattern may cover multiple databases in case such databases are actually running on the same database machine.
Maximum number of connections allowed for the database matching the URL pattern
The priority of this intercepted method in the interceptor chain. An interceptor with a higher priority will be executed earlier than an interceptor with a lower priority.
Note: 1073741823 is actually Integer.MAX_VALUE / 2 as defined in InterceptorPriorities.
