Managing Shared Memory

Managing shared memory includes the following tasks:

• Changing the size or number of buffers (by changing the size of the logical-log or physical-log buffer, or changing the number of buffers in the shared-memory buffer pool)
• Changing shared-memory parameter values, if necessary
• Changing forced residency (on or off, temporarily or for this session)
• Tuning checkpoint intervals
• Adding segments to the virtual portion of shared memory
