Subject Internal Statements in Derby
Date Thu, 15 Feb 2007 09:02:02 GMT

As a part of my Master Thesis at NTNU, Trondheim I am trying to  
implement a Hot-Standby scheme between two Derby databases located on  
different hosts. So far the primary derby database creates logical  
log records and ships these to the Hot-Standby database. However, I  
am having some trouble making the Hot-Standby derby to redo the  
statements when they are committed on the primary node.

Is there a way to run internal sql statements from within a Derby  
database with no active connections? I have tried to use the  
prepareInternalStamement(sql) from the  
GenericLanguageConnectionContext, but it needs an active connection,  
which Hot-Standby databases do not have by definition.

It is important to do the operation at a high enough abstraction so  
that the operation is logged with the physical logger as well.
