Purpose

This bulletin aims to clarify the architectural changes in Oracle 10g on UNIX to reduce potential conflicts when implementing a client signal handler in code that connects to Oracle via the BEQUEATH adapter. It highlights the options available to facilitate this type of implementation and also identifies the trade-offs that should be considered.

Scope

Developers, Database Administrators, System Architects, planning to implement client code with a client-side signal handler which connects to Oracle via a BEQUEATH connection, particularly where the handler will deal with SIGCLD signals.

It assumes some understanding of UNIX concepts, such as process forking, the system init process and zombie processes. It does not attempt to explain these concepts.

It affects most UNIX platforms.
