Transation Isolation Levels

Discussing with a colegue about defining transactions in our application we finished by talking about transaction isolation levels and finally I got into problems explaining the problems faced in concurrent transactions (I wasn’t able to tell the difference between non-repeatable and phantom reads [sigh/]).

Becoming an Architect

Becoming an Architect
Luke Hohmann: Most people think of architecture as technical, and the architect as a technical person. And absolutely, the architect must be technical.

Tomcat – JRockit

Found this on this weblog: Random thoughts:

Manageability quoting Rod Johnson

Manageability – Rod Johnson on J2EE Without EJB:
An interesting listing of EJB offerings and their utility:

Declarative Transactions: Good but not always appropiate.
Remoting: Best choice today for remoting.
Clustering:Entity and SFSB have weak implementations.SLSB clustering isn’t rocket science. Clustering more important on the web and database tier.
Thread Management:Locking entire bean instances is naive. Multi-threaded services without read/write [...]
