Corba Interview Question:

Explain the reason to implement a corba application with multi-threading?

Submitted by: Administrator

CORBA server applications may be multi-threaded for serveral reasons.
A particular CORBA object may support an operation whose implementation performs some blocking routine. This may be a disk read or database query. Let us assume that the server application processes all CORBA events within a single main thread. This means that the server will be unable to respond to incoming connection requests or invocation requests while the blocking operation is in progress. Multi-threading can be used to avoid these sorts of situations. The server can be more accessible if multiple threads are allowed to process (an block during) incoming CORBA events.
A single multi-threaded server process supporting many (>25) clients is much more efficient that many (>25) single-threaded server processes each supporting its own client. Running a single application with multiple threads requires less machine resources than running multiple applications. This advantage can be seen even if the operation invocations are of short duration and non-blocking.
