Hi ,
Oracle database system uses very complicated lock/unlock design for readlock,writelock and row/recordlock etc..... Does anyone know lock/unlock is implemented both client like sqlplus and server side or just on server side or just client side. For instance, one user using sqlplus access database to update one record of table XX. So should be sqlplus's responsibility to lock this record based on row level of XX table? or server is also involved in? Thanks.
