Interface OracleJDBCConnectionPoolStatistics

All Superinterfaces:

JDBCConnectionPoolStatistics, UniversalConnectionPoolStatistics

public interface OracleJDBCConnectionPoolStatistics
extends JDBCConnectionPoolStatistics

Various runtime statistics for the Universal Connection Pool that are specific to Oracle JDBC resources. This interface provides query-only operations on all available pool statistics.

java.lang.String	getFCFProcessingInfo() Gets the information of recent Fast Connection Failover (FCF) attempts, in the form of a String.
java.lang.String	getFCFProcessingInfoProcessedOnly()
long	getSuccessfulAffinityBasedBorrowCount() Gets the number of borrow requests that succeeded in matching affinity contexts.
long	getSuccessfulRCLBBasedBorrowCount() Gets the number of borrow requests that succeeded in using the Runtime Connection Load-Balancing (RCLB) algorithms.

Method Detail

getSuccessfulAffinityBasedBorrowCount

long getSuccessfulAffinityBasedBorrowCount()

Gets the number of borrow requests that succeeded in matching affinity contexts.

Returns:

The number of borrow requests that succeeded in matching affinity contexts.

getFailedAffinityBasedBorrowCount

long getFailedAffinityBasedBorrowCount()

Gets the number of borrow requests that returned connections not matching the affinity contexts.

Returns:

The number of borrow requests that returned connections not matching the affinity contexts.

getSuccessfulRCLBBasedBorrowCount

long getSuccessfulRCLBBasedBorrowCount()

Gets the number of borrow requests that succeeded in using the Runtime Connection Load-Balancing (RCLB) algorithms.

Returns:

The number of borrow requests that succeeded in using Runtime Connection Load-Balancing (RCLB) algorithms.

getFailedRCLBBasedBorrowCount

long getFailedRCLBBasedBorrowCount()

Gets the number of borrow requests that failed to use Runtime Connection Load-Balancing (RCLB) algorithms.

Returns:

The number of borrow requests that failed to use Runtime Connection Load-Balancing (RCLB) algorithms.

getFCFProcessingInfo

java.lang.String getFCFProcessingInfo()

Gets the information of recent Fast Connection Failover (FCF) attempts, in the form of a String. The information returned is to help diagnosing FCF problems, and includes the outcome of each FCF attempt (successful or failed), the relevant Oracle RAC instances, the number of connections cleaned up, the exception that triggered the FCF attempt failure, and so forth.

Returns:

The information string for recent FCF attempts.

getFCFProcessingInfoProcessedOnly

java.lang.String getFCFProcessingInfoProcessedOnly()
