Some operating systems, such as Windows, hold two levels of system settings: user settings and local machine settings.
Current user settings are specific to an individual user and are used only when that user is logged on. Local machine settings are global to the machine and are available no matter which user is logged on;. You must have administrator permissions on your machine to make local machine settings.
SAP Sybase IQ permits the use of both current user and local machine settings. For Windows, these settings are held in the HKEY_CURRENT_USER registry and HKEY_LOCAL_MACHINE registry, respectively.
The SAP Sybase IQ installation lets you choose whether the settings it makes are for the current user only or at the local machine level.
If you make settings in both current user and local machine registries, the current user setting takes precedence over the local machine setting.
If you are running a SAP Sybase IQ program as a service on Windows, ensure that the settings are made at the local machine level.
Services can continue to run under a special account when you log off a machine, as long as you do not shut the machine down entirely. Services can be made independent of individual accounts and need access to local machine settings.
In general, use local machine settings.
