11Adjust the operating system shared memory parameter.

For Adaptive Server to run, the operating system must be configured to allow allocation of a shared memory segment at least as large as the Adaptive Server total logical memory configuration parameter.

The default total logical memory parameter for HP is 32,768 2K pages (64MB) on the 32-bit operating system, and 45,056 2K pages (88MB) on the 64-bit operating system. To adjust the shared memory value of the operating system, use the System Administration Manager (SAM).

After you install Adaptive Server, you can change any configuration parameter, procedure cache, and data cache size. This may require that you increase the value of the configuration parameter max memory.

Depending on the number and types of devices you use for backup (dump) and recovery (load), you may need to adjust the
