com.highqsoft.asamodsping.Ping

public class Ping
extends java.lang.Object

This class can be used to reconnect an ASAM ODS server to the configured database. In some cases it could be that the database server was down since the last ASAM ODS session. May be that there are some maintenance work or hardware problems that stop the database server. This program tries to reconnect

Property Keyword	Datatype	Default	Description
Properties	String	null	A file containing ping properties. Properties that additionally added at command line have higher priority than these from file.
NameServiceName	String	NameService	The name of the requested CORBA Name Service.
NameServicePort	int	900	The port number of the requested CORBA Name Service.
NameServiceHost	String	localhost	The host name of the requested CORBA Name Service.
CORBAProtocol	String	""	The CORBA protocol in the corbaloc (CORBA locator) to find the name service. The default of CORBA is iiop, which is identical with an empty string "". For IIOP over SSL the protocol must be ssliop. This value is an application property.
ServiceName	String	empty	The service to be used.
SessionFactoryOptions	String	none	Implementation dependent options passed to the session factory when the session factory is instantiated. This option could contain something like "DEBUGLEVEL=3".
Username	String	empty	The name of the user used to connect to server.
Password	String	empty	The password of the user used to connect to server.
Waits	int[]	[10, 10, 100, 10000]	An array of integer defining the total number of loops and the sleep time in seconds for reconnection.
StdOut	File	none	The name of a file that tool uses as standard output stream.
StdErr	File	none	The name of a file that tool uses as standard error stream.
NumberParallel	integer	1	The number of parallel access
Duration	integer	0	The duration the parallel access are tested, 0 means only 1 time. The duration is given in minutes.
EncodePassword	boolean	false	In case this property is true the password is encoded.
