The VORTEX_SHM_BASE environment variable sets the base shared memory address for system catalog caching.


A hexadecimal value for the shared memory subsystem address that will be used as the base address for system catalog caching. This value is either 8 or 16 digits and must be in the correct format for the underlying architecture. (For example, on x86 systems, use 00000008 for address 80000000.) If this environment variable is not set (which is the default), the operating system determines this address.


On UNIX systems you may need to set the base address for system catalog caching. See Adjusting the shared memory subsystem settings. Synergy/DE Developer Support may ask you to set this on other operating systems as well.
