RllRAMAccessManager
public class RllRAMAccessManager extends RAMAccessManager (Code)
Implements the row level locking accessmanager.



Constructor Summary
public  RllRAMAccessManager()
    

Method Summary
protected  voidbootLookupSystemLockLevel(TransactionController tc)
     Query property system to get the System lock level.

This routine will be called during boot after access has booted far enough, to allow access to the property conglomerate.

protected  intgetSystemLockLevel()
     Return the locking level of the system.

This routine controls the lowest level of locking enabled for all locks for all tables accessed through this accessmanager.



Constructor Detail
RllRAMAccessManager
public RllRAMAccessManager()(Code)
Constructors for This class:




Method Detail
bootLookupSystemLockLevel
protected void bootLookupSystemLockLevel(TransactionController tc) throws StandardException(Code)
Query property system to get the System lock level.

This routine will be called during boot after access has booted far enough, to allow access to the property conglomerate. This routine will call the property system and set the value to be returned by getSystemLockLevel().


exception:
  StandardException - Standard exception policy.




getSystemLockLevel
protected int getSystemLockLevel()(Code)
Return the locking level of the system.

This routine controls the lowest level of locking enabled for all locks for all tables accessed through this accessmanager. The concrete implementation may set this value always to table level locking for a client configuration, or it may set it to row level locking for a server configuration.

If TransactionController.MODE_RECORD is returned table may either be locked at table or row locking depending on the type of access expected (ie. level 3 will require table locking for heap scans.) TransactionController.MODE_TABLE if only table locking allowed,else returns TransactionController.MODE_RECORD.
