Class ReloadCommand

java.lang.Object

com.aspc.commander.Command

com.aspc.commander.sql.SQLCommand

com.aspc.commander.sql.ReloadCommand

All Implemented Interfaces:

CommandBuildResultsPlugin

public class ReloadCommand
extends SQLCommand

RELOAD will scan the transaction header for the records changed in that
period and make sure that the records are the latest version in memory.
ie. exactly as if it had received the messages for it.

That way if we have another JMS outage we can tell the server to RELOAD
'1 hour' and all the messages for the last hour would be replaied.
Syntax

  RELOAD [TRANSACTIONS period]|[CLASS class_name [WHERE clause]]
  

Usage

  RELOAD TRANSACTIONS '1 hour' -- Reload all record that were changed in the last hour
  

THREAD MODE: SINGLE THREADED command
