Brief introduction
To understand the new multithreaded functionality in DB2 9.5, this article first discusses the DB2 process model. The entire DB2 process model is controlled by the Base System Utilities (bsus). BSU allocates memory for instance and database, intercepts and processes signals, and handles exceptions sent to DB2. Figure 1 shows the old DB2 process model for Linux and UNIX platforms.
