/** | |
* <p> | |
* <b>Purpose</b>: Define interface for sequencing server. | |
* <p> | |
* <b>Description</b>: This interface accessed through | |
* ServerSession.getSequencingServer() method. | |
* Used for creation of ClientSessionSequencing object | |
* and for access to sequencing connection pool. | |
* Note that if session is disconnected ServerSession.getSequencingServer() always returns null. | |
* Setup of SequencingConnectionPool is done only through SequencingControl interface. | |
* Even if getSequencingControl().setShouldUseSeparateConnection(true) is specified, | |
* SequencingConnectionPool is NOT created unless the session has at least one Sequence object | |
* that requires transaction. | |
* <p> | |
* <b>Responsibilities</b>: | |
* <ul> | |
* <li> Connects sequencing on ClientSession with sequencing on ServerSession. | |
* </ul> | |
* @see ClientSessionSequencing | |
