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.)
getSystemLockLevel in class RAMAccessManagerprotected void bootLookupSystemLockLevel(TransactionController tc) throws StandardException
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().
