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.

Method Summary

Modifier and Type	Method	Description
String	getColocationStats()	Get processing info for COLOCATION_TAG support.
long	getConnectionRepurposeCount()	Returns the number of connection repurposed in a shared pool for a mutitenant database, where connections can be reused across PDB's by switching their container and PDB service.
long	getFailedAffinityBasedBorrowCount()	Gets the number of borrow requests that returned connections not matching the affinity contexts.
long	getFailedRCLBBasedBorrowCount()	Gets the number of borrow requests that failed to use Runtime Connection Load-Balancing (RCLB) algorithms.
String	getFCFProcessingInfo()	Gets the information of recent Fast Connection Failover (FCF) attempts, in the form of a String.
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 Details

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

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

String getFCFProcessingInfoProcessedOnly()

getConnectionRepurposeCount

long getConnectionRepurposeCount()

Returns the number of connection repurposed in a shared pool for a mutitenant database, where connections can be reused across PDB's by switching their container and PDB service.

Returns:

repurpose count

getColocationStats

String getColocationStats()

Get processing info for COLOCATION_TAG support. This currently contains only information on whether all the non-applicable HA features are disabled.

Returns:

String with processing info for COLOCATION_TAG support.
