Custom report PERFORMANCE_DASHBOARD_MAIN.RDL, load and see the Performance Analysis report:Performance dashboard does not collect or store any information, but instead extracts the current data from within SQL Server.

location on a separate server.replicas can be kept in sync with the source data continuously or at scheduled intervals. One-way synchronization and bidirectional synchronization are possible. Replication can even be used to keep several datasets in sync with each other. at the first level, I'll cover basic replication components and describe how they work together to replicate data and change data. We'll also look at a detailed example of setting up a simple replication scenario. Replication

maximum server memory. If this parameter is not set, BPool only sets about 128 MB for use by other processes and locks all the remaining physical memory on the machine. Then, BPool uses the memory above 3 GB (AWE memory) as the paging files for data and indexing. It splits these areas (above 3 GB) the physical memory page is mapped to the appropriate virtual memory address space, so that the 32-bit pointer can be referenced. ReviewThis part is not tr
