C# Класс ACR_DatabaseConnector.DatabaseConnector

This class handles secure database transport connection management. In this implementation, a PLINK.EXE process is created and monitored for the SSH port forward used to access the central MySQL database server.

Метод	Описание
DatabaseConnector ( CLRScriptFramework Script ) : System	Create a new DatabaseConnector object, which manages the secure tunnel to the database. If the tunnel is not enabled, then the object does nothing and returns immediately, otherwise, the tunnel process is started (and monitored and restarted in the event of a connection failure). In this case, the game server has two minutes to successfully connect to the tunnel or else the server process will be exited, because a game server does not function without a database being present during startup. During the wait for the database to come online, the logger queue is periodically written out by this module as the ACR_ServerCommunicator (which normally assumes responsibility for flushing the logger queue to the server log file) has not yet been initialized.

AssignProcessToJobObject ( IntPtr hJob, IntPtr hProcess ) : int
CloseHandle ( IntPtr hObject ) : int
ConfigureJob ( SafeWaitHandle Job ) : void	Configure a job object for use by the database connector. It is set up so that once the last job handle lapses, all of the processes joined to the job are terminated.
CreateJob ( ) : SafeWaitHandle	Create a job object.

DatabaseConnectionMonitorThread ( ) : void	The thread procedure for the thread that monitors the PLINK.EXE instance that provides a secure SSH port forward to the MySQL database. Initially, it creates a PLINK.EXE process, and from that point it ensures that if the PLINK.EXE process closes, that a new process is started to connect out to the database automatically in the event of a temporary connectivity interruption.
ExtractResource ( string FileName, byte ResourceData ) : string	Extract a resource to disk.
