The process of inserting data into column-organized tables, or updating previously inserted data, is optimized for large insert transactions. As a result, workloads that are transactional in nature should not use column-organized tables. Traditional row-organized tables with index access are generally better suited for these types of workloads. With column-organized tables, performance is optimal if or more rows are impacted by each insert or update transaction.
Agent stack size configuration parameter. This parameter determines the memory that is allocated by Db2 for each agent thread stack. Application support layer heap size configuration parameter. The application support layer heap represents a communication buffer between the local application and its associated agent. This buffer is allocated as shared memory by each database manager agent that is started. Audit buffer size configuration parameter.
This parameter specifies the size of the buffers used when you audit the Db2instance. First, MDC enables a table to be physically clustered on more than one key, or dimension, simultaneously. As a result query performance is improved where there is a clustering of one or more specified dimensions of a table. Consequently not only will these queries access only those pages having records with the correct dimension values, but these qualifying pages will also be grouped into blocks, or extents.
Second, although a table with a clustering index can become unclustered over time, in most cases an MDC table is able to maintain and guarantee its clustering overall dimensions automatically and continuously. Third, in MDC the clustering indexes are block-based. These indexes are much smaller than regular record-based indexes, hence they take up much less disk space and are faster to scan.
