Understanding how DB2 uses memory can prevent over-allocating memory and help tune memory usage for better performance.This article will teach you the basics of DB2 memory usage, as well as the concept of shared memory and private memory. These contents apply to both 32-bit and 64-bit systems. Although there are some limitations on 64-bit systems, they are unlikely to reach these limits for some time to com
The following articles mainly describe the correct steps for DB2 backup and cross-platform migration. If you are curious about the correct steps for DB2 backup and cross-platform migration, the following articles will unveil its secrets. The following is a detailed description of the article.
