What would happen when a linked application to a shared memory terminates
abnormally while it is in the middle of memory allocation or any other
structural changes? I guess it could corrupt the whole shared memory and also
stability of the other linked applications.
Some shared-memory based databases like TimesTen have a mechanism called
MicroLogging to protect integrity of the shared memory.
Here is a quote from Oracle TimesTen:
"Oracle TimesTen protects its shared libraries against application process
failures by means of its patented “MicroLogging†algorithm. Consequently, the
abnormal termination of a linked application will not affect Oracle TimesTen
IMDB's and even other related applications."
