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 HCL Informix® Performance Guide.
