Manage shared memory
These topics inform you how to perform the following tasks, which concern managing shared memory:
- Setting the shared-memory configuration parameters
- Setting up shared memory
- Turning residency on or off for the resident portion of the database server shared memory
- Adding a segment to the virtual portion of shared memory
- Reserving memory for critical activities
- Maintaining a targeted amount of memory in applications with memory limitations
- Monitoring shared memory
These topics do not cover the DS_TOTAL_MEMORY configuration parameter. This parameter places a ceiling on the allocation of memory for decision-support queries. For information about this parameter, see your IBM® Informix® Performance Guide.
