The Legacy Landscape handle allowed for a total model count of 1,048,576 models per SpectroSERVER (SS). The bit mode mask has been changed, and with CA Spectrum 10.2 the "Huge Landscape Handle" option drastically increases that model count to approximately 16,000,000. While you can technically create that many models on one SS, CA will support 2,000,000 models per SS with CA Spectrum 10.2. If you create more than 2,000,000 models and experience performance problems, CA reserves the right to request you utilize another SpectroSERVER to move models.
If you are upgrading a previously saved SpectroSERVER database (SSdb), you will not have the option to choose. The install will automatically default to the Legacy Landscape Handle.
If you migrate a previously saved SSdb (using the <SPECROOT>/SS/dbsavefile.SSdb method), you MUST choose the Legacy Landscape Handle.
The Legacy Landscape Handle needs to be selected when the following are true:
You need to upgrade or migrate a SpectroSERVER database from before 10.2 on any SS in a DSS.
They are in multiples of 4. For example:
4 - 0x100000
8 - 0x200000
12 - 0x300000
16 - 0x400000
20 - 0x500000
The Huge Landscape Handle needs to be selected when the following are true:
You are installing fresh and you are not upgrading or migrating a previously saved SpectroSERVER database file.
If you are installing fresh and using modeling gateway on all SS in 10.2, then select this option.
All SpectroSERVERs in your distributed SpectroSERVER environment will utilize the Huge Landscape Handle.
They are in multiples of 64. For example:
64 - 0x1000000
128 - 0x2000000
192 - 0x3000000
256 - 0x4000000
320 - 0x5000000
