getConnectionLeakProfileCount

int getConnectionLeakProfileCount()

Deprecated. 

Connection leak is a situation when connection from the pool was not closed explicitly by calling close() and was garbage collected.

This method should be used first before requesting connection leak profiles from the profile storage.

Returns:

Number of the connection leak profiles in profile storage.

getConnectionLeakProfiles

JDBCConnectionLeakProfile[] getConnectionLeakProfiles(int index,
                                                      int count)

Deprecated. 

Connection leak profiling stores stack trace at the time when connection was created in case of connection leak. This enables you to identify where the leak occurred.

Connection leak is a situation when connection from the pool was not closed explicitly by calling close() and was garbage collected.

Returns:

Connection leak profiles starting from this index. Number of returned profiles depends on factual number of profiles in the profile storage.

JDBCConnectionLeakProfile

getStatementProfileCount

int getStatementProfileCount()

Deprecated. 

SQL roundtrip profiling stores SQL statement text, execution time and other metrics.

This method should be used first before requesting SQL statement profiles from the profile storage.

Returns:

Number of the SQL statement profiles in profile storage.

getStatementProfiles

JDBCStatementProfile[] getStatementProfiles(int index,
                                            int count)

Deprecated. 

SQL roundtrip profiling stores SQL statement text, execution time and other metrics.

Returns:

Statement profiles starting from this index. Number of returned profiles depends on factual number of profiles in the profile storage.

JDBCStatementProfile

testPool

String testPool()

Deprecated. 

Test the pool by reserving and releasing a connection from it. If the pool configuration attribute TestConnectionsOnReserve or TestConnectionsOnRelease is enabled, the acquired connection is also tested as part of the reserve and release operation.

Returns:

returns null upon success, else returns stacktrace

getLeakedConnectionCount

int getLeakedConnectionCount()

Deprecated. 

Returns:

Number of leaked connections. Leaked connection is a connection that was checked out from the connection pool but was not returned to the pool by calling close ().

getPoolState

boolean getPoolState()

Deprecated. 

Returns:

Current state of the connection pool. true if the pool enabled. false if the pool disabled

isEnabled

boolean isEnabled()

Deprecated. 

Returns:

Boolean indicating pool is enabled or disabled. true if the pool is enabled. false if the pool is disabled.

getState

String getState()

Deprecated. 

The current state of the connection pool.

Possible values are:

• Running

  if the pool is enabled (deployed and not Suspended). This is the normal state of the connection pool.

• Suspended

  if the pool disabled.

• Shutdown

  if the pool is shutdown and all database connections have been closed.

• Unknown

  if the pool state is unknown.

• Unhealthy

  if all connections are unavailable (not because they are in use). This state occurs if the database server is unavailable when the connection pool is created (creation retry must be enabled) or if all connections have failed connection tests (on creation, on reserve, on release, or periodic testing).

Returns:

Current state of the connection pool.
