removeHost

public void removeHost(String hostPortPair)
                throws SQLException

Remove the given host (host:port pair) from this Connection Group.

参数:

hostPortPair - The host:port pair to remove.

抛出:

SQLException - if a database access error occurs

public void removeHost(String hostPortPair,
                       boolean removeExisting)
                throws SQLException

Remove the given host (host:port pair) from this Connection Group.

参数:

hostPortPair - The host:port pair to remove.

removeExisting - Whether affects existing load-balanced connections or only new ones.

抛出:

SQLException - if a database access error occurs

removeHost

public void removeHost(String hostPortPair,
                       boolean removeExisting,
                       boolean waitForGracefulFailover)
                throws SQLException

Remove the given host (host:port pair) from this Connection Group and, consequently, from all the load-balanced connections it holds.

参数:

hostPortPair - The host:port pair to remove.

removeExisting - Whether affects existing load-balanced connections or only new ones.

waitForGracefulFailover - If true instructs the load-balanced connections to fail-over the underlying active connection before removing this host, otherwise remove immediately.

抛出:

SQLException - if a database access error occurs

addHost

public void addHost(String hostPortPair)

Add the given host (host:port pair) to this Connection Group.

参数:

hostPortPair - The host:port pair to add.

addHost

public void addHost(String hostPortPair,
                    boolean forExisting)

Add the given host (host:port pair) to this Connection Group and, consequently, to all the load-balanced connections it holds.

参数:

hostPortPair - The host:port pair to add.

forExisting - Whether affects existing load-balanced connections or only new ones.
