However, if the trail is a large operation or a large amount of work is performed at the same time, a large Trace Buffer may be required. On most platforms, tracking can be enabled and work at any time as described above. Note: In a multi-database partition system, you must track the running of each physical

Before we discuss the specifics of this solution in terms of unified access, distribution, and heterogeneity, we need to turn our attention to the communications infrastructure itself. DB2 Connect provides this communication infrastructure in the form of a communication
