Entering a Landscape Handle
Procedure
In the Landscape Handle box (see Figure 17 [page 63]
), type a numeric
value that is a multiple of 4 and is between 4 and 16,376 to serve as a
unique identifier for each SpectroSERVER you are installing. You can also
enter hexadecimal values in the range from 0x100000 to 0xffe00000,
where the lower 20 bits are set to zero.
On Solaris systems, you can convert a decimal value to the proper format
for a SPECTRUM hexadecimal landscape handle by running the following
three commands:
1. bc
2. obase=16
3. <decimal value> * 262144
The bc utility displays a hexadecimal value that you enter in the Landscape
Handle field, prefixed by 0x. For example, a decimal value of 24 multiplied
by 262144 will yield a hexadecimal value of 600000. You would enter
0x600000 in the Landscape Handle field.
If you are migrating or upgrading an existing database, its landscape
handle is listed in this field. However, this field is not editable for
upgrade/migration installations.
WARNING! If your existing landscape handle is not evenly
divisible by 4 and within the range of 4 to 16,376,
you must exit the installation and assign a valid
landscape handle using the SPECTRUM landscape
handle conversion utility (see SpectroSERVER
Landscape Handle Requirements [page 14]).
Unique landscape handles are crucial if you are configuring a distributed
SpectroSERVER environment (see SpectroSERVER Landscape Handle
Requirements [page 14]).
