Sets the maximum number of physical processors that can be used (up to the licensed maximum). This option is only useful on multiprocessor systems.

If the -gt value specified lies outside this range, the lower or upper limit is imposed.
With per-seat licensing, the network database server uses all CPUs available on the computer. With CPU-based licensing, the network database server uses only the number of processors you are licensed for. The number of CPUs that the network database server can use may also be restricted by your SAP Sybase IQ edition.
When you specify a value for the -gt option, the database server adjusts its affinity mask (if supported on that hardware platform) to restrict the database server to run on only that number of physical processors. If the database server is licensed for n processors, the server, by default, runs on all logical processors (hyperthreads and cores) of n physical processors. This behavior can be further restricted with the -gtc option.
The -gt option cannot be used with the -gta option.
