Class SystemProperties

java.lang.Object

com.gemstone.gemfire.internal.shared.SystemProperties

public final class SystemProperties
extends Object

Set the global system properties. This class is the supported way to change system properties before client (or server) side API is invoked that uses one or more properties defined in the class.

Since:

gfxd 1.1

Field Detail

KEEPALIVE_IDLE

public static final String KEEPALIVE_IDLE

TCP KeepAlive IDLE timeout in seconds for the network server and client sockets. This is the idle time after which a TCP KeepAlive probe is sent over the socket to determine if the other side is alive or not.

Constant Field Values

KEEPALIVE_INTVL

public static final String KEEPALIVE_INTVL

TCP KeepAlive INTERVAL timeout in seconds for the network server and client sockets. This is the time interval between successive TCP KeepAlive probes if there is no response to the previous probe (KEEPALIVE_IDLE) to determine if the other side is alive or not.

Note that this may not be supported by all platforms (e.g. Solaris), in which case this will be ignored and an info-level message logged that the option could not be enabled on the socket.

Constant Field Values

KEEPALIVE_CNT

public static final String KEEPALIVE_CNT

TCP KeepAlive COUNT for the network server and client sockets. This is the number of TCP KeepAlive probes sent before declaring the other side to be dead.

Note that this may not be supported by all platforms (e.g. Solaris), in which case this will be ignored and an info-level message logged that the option could not be enabled on the socket.

Method Detail

isUsingGemFireXDEntryPoint

public static boolean isUsingGemFireXDEntryPoint()

getServerInstance

public static SystemProperties getServerInstance()

Get an instance appropriate for server instances. Usually this will use a different prefix and means of reading file properties than "client" instances.

getClientInstance

public static SystemProperties getClientInstance()

Get an instance appropriate for client instances. Usually this will use a different prefix and means of reading file properties than "server" instances.

NOTE: This will also read server prefixed instances as fallback to handle the case for few common properties (like in ClientSharedUtils) when used in JVMs that are configure to be both client and server.

getGFXDServerCallbacks

public static SystemProperties.Callbacks getGFXDServerCallbacks()

setCallbacks

public void setCallbacks(SystemProperties.Callbacks cb)

getCallbacks

public SystemProperties.Callbacks getCallbacks()

getString

public String getString(String name,
                        String defaultValue)

getInteger

public int getInteger(String name,
                      int defaultValue)

getLong

public long getLong(String name,
                    long defaultValue)

getBoolean

public boolean getBoolean(String name,
                          boolean defaultValue)

getSystemPropertyNamePrefix

public String getSystemPropertyNamePrefix()
