During a new install of DX NetOps Spectrum, the landscape handle selection screen has been changed to allow the selection of the Legacy Landscape Handle or a Huge Landscape Handle:
Previous Spectrum deployments only allowed for a limited amount of models to be created on each SpectroSERVER. The CA Spectrum 10.2 code has been enhanced to allow for more models per SpectroSERVER, which will help to reduce the total number of SpectroSERVERs needed.
Release: All Supported Releases
Component: SPCINS - Install/Upgrade
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:
The Huge Landscape Handle needs to be selected when the following are true:
When merging databases in 10.2, you may opt to take your MLS SSdb from the pre 10.2 environment and use that as your 10.2 MLS SSdb so that you keep all models and SS configurations. If you do this, you must choose the legacy landscape handle on ALL SS installs. If you do not utilize any of your SSdb, and instead will use modeling gateway to export the modeling info from all SS and import it to 10.2, then select the huge landscape handle during install.
