To support synchronous or synchronous residual time stamp (SRTS) clocking modes, you must specify a primary reference source to synchronize the flow of constant bit rate (CBR) data from its source to its destination. You can specify up to four clock priorities. The highest priority active inte...
the SQLCipher package includes it's own independent tests that exercise and verify the core functionality of the SQLCipher extensions. This test suite is intended to provide an abbreviated verification of SQLCipher's internal logic; it does not perform an exhaustive test of the SQLite database syste...
You can't perform a point-in-time restore on a geo-secondary database. You can do so only on a primary database. TheBackupFrequencyparameter isn't supported for Hyperscale databases. Database restore operations are resource-intensive and might require a service tier of S3 or greater for the...
For example, if an external library with POJOs is being used and it is desired to map those POJOs to the database, there is no easy way of annotating the source code. Another case this applies is if different mapping parameters are needed between different environments. For example, embedded...
Like a View structure, a Commands structure requires a computed body property that uses builder semantics, except with commands instead of views. Step 4 Add a SidebarCommands command to the body. This built-in command set includes the command for toggling the sidebar. To make use of commands ...
For example, with a programmed update rate of 19.8 Hz, rejection notches at 50 and 60 Hz can be achieved simultaneously.Figure 1. AD7719 functional block diagram.The peak-to-peak resolution depends on the programmed gain and the output data rate. The device operates from a single +3-V o...
What drives companies to have a successful data-driven culture? It’s important to understand that it’s not necessarily about the data itself. That’s secondary. The technology itself comes in third. Data-driven decision-making is first and foremost about the organization. ...
What are the core components of a data center? Data center design includesrouters,switches, firewalls,storage systems,servers, and application delivery controllers. Because these components store and manage business-critical data and applications, data center security is critical in data center design. ...
If you perform a primary/secondary switchover on the source database when the data synchronization task is running, the task fails. The data synchronization task fails if the source database contains an empty string of the VARCHAR2 type and the corresponding colu...
