Method Detail

getConnection

Connection getConnection()

Returns java.sql.Connection

Returns:

connection as java.sql.Connection

setDriverName

void setDriverName(String driverName)

Returns:

connection URL

setUserName

void setUserName(String userName)

Sets database user

Parameters:

userName - database user

getUserName

String getUserName()

Returns database user name

Returns:

current database user name

setPassword

void setPassword(String password)

Sets database user password

Parameters:

password - database user password

setMinPool

void setMinPool(int minPool)

Sets minimum number of connections in the connection pool

Parameters:

minPool - minimum number of connections

getMinPool

int getMinPool()

Returns minimum number of connections in the connection pool

Returns:

connection minPool

setMaxPool

void setMaxPool(int maxPool)

Sets maximum number of connections in the connection pool

Parameters:

maxPool - maximum number of connections

getMaxPool

int getMaxPool()

Returns maximum number of connections in the connection pool

Returns:

connection maxPool

setMsInterval

void setMsInterval(int msInterval)

Sets the amount of time, in milliseconds, between the connection manager's attempts to get a pooled connection.

Parameters:

msInterval - the interval between attempts to get a database connection, in milliseconds.

getMsInterval

int getMsInterval()

Returns the amount of time, in milliseconds, between the connection manager's attempts to get a pooled connection.

Returns:

the length of the interval between tries in milliseconds

setMsWait

void setMsWait(int msWait)

Sets the number of milliseconds to wait for an available connection from the connection pool before throwing an exception

Parameters:

msWait - number in milliseconds

getMsWait

int getMsWait()

Returns the number of milliseconds to wait for an available connection from the connection pool before throwing an exception

number in milliseconds

setLogWriter

void setLogWriter(PrintWriter logWriter)

Sets the LogWriter to which messages should be sent

Parameters:

logWriter -

getLogWriter

PrintWriter getLogWriter()

Returns the LogWriter to which messages should be sent

Returns:

logWriter

setLoginTimeout

void setLoginTimeout(int loginTimeout)

Sets the number of seconds to wait for a new connection to be established to the data source

Parameters:

loginTimeout - wait time in seconds

getLoginTimeout

int getLoginTimeout()

Returns the number of seconds to wait for a new connection to be established to the data source

Returns:

wait time in seconds

setTransactionIsolation

void setTransactionIsolation(int level)

Sets transaction isolation level for all connections of this ConnectionFactory. All validation is done by java.sql.Connection itself, so e.g. while Oracle will not allow to set solation level to TRANSACTION_REPEATABLE_READ, this method does not have any explicit restrictions

Parameters:

level - - one of the java.sql.Connection.TRANSACTION_* isolation values

getTransactionIsolation

int getTransactionIsolation()

Returns current transaction isolation level for connections of this ConnectionFactory.

Returns:

the current transaction isolation mode value as java.sql.Connection.TRANSACTION_*
