Thank you very much for your response. But how oracle design let server to handle locks. There are lots of overheads because lots of clients can access server at a same time. If client handles individually, They will release lots of overburden for server. And server just make sure that only owner of lock can unlock CS. Anywhere we can find those information.

Thanks.

Hi,

All locking is handled by the server, not client

Please respond

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 serve! ! ! r is also involved in? Thanks.
