Sortheap and sheapthres sortheap are a database configuration parameter that defines the maximum number of private memory pages used by private or shared sorting. Each sorting has an independent sorting heap, which is allocated by the database manager as needed. Generally, we can understand that when the memory size required for a sorting task exceeds sortheap, the sorting overflow occurs, if the statistical information is out of date, or the data is biased, and published statistics are not coll

discussed different connection methods available in DB2. As we know, some methods seem to be a better choice than other methods. For example, compared with nested loop connections of tables scanned in each row of the External table, the combined connections have the advantage of only scanning the table once. Therefore, merging connections seems to be a better choice. However, if an index exists, nested loops will be a better choice. Similarly, the ha

This time, our DB2 is deployed on Windows. Windows has a client that is called a graphical interface. But it does not seem to work well, we have some problems, let's solve it. First, add a database instance: Instances of DB2 are independent of each other, and instances can be considered as containers for databases. When the default DB2 is installed, it builds an
