It also happens whenever you switch on your console after not shutting it down properly.

It’s also worth noting that major PS4 updates also require a database rebuild. In our experience, the process takes a few minutes, at most, on a 1 TB PS4 Pro.
Sony warns that rebuilding your database can take a while-or even a few hours, depending on how much new data there is to sift through. After the database is rebuilt, the console notes where the relevant data is on the drive, and then updates its location within the database. Defragmenting moves data around, whereas rebuilding the database only affects the database. This isn’t the same as defragmenting a hard drive-that process would take much longer. This can lead to faster boot times and a more responsive console. Once this process is complete, it’s easier for your console to find the data it needs for a particular game or service. Rebuilding your PS4’s database tells the system where the relevant downloaded data resides on the drive. Much of this data isn’t relevant to the current operation, though. A few big updates and game downloads can cause your console to slow down, as it has to sift through a lot of data.

When your Sony PlayStation 4 downloads data, whether it’s a new game or an update to an existing title, the console must sift through the downloaded data to find what it needs. What Does “Rebuild the PS4 Database” Mean? For details check this post from the SQL Server Blog. Introduced in SQL Server 2014, for operations the ONLINE = ON option now contains a WAIT_AT_LOW_PRIORITY option which permits you to specify how long the rebuild process should wait for the necessary locks. Each stage of an online index build operation generates an event.Įxample: CREATE CLUSTERED INDEX cix_SalesOrderDetail_demo_soid ON (SalesOrderDetailID) Occurs during an online index build process to indicate the progress of the build operation. Introduced in SQL Server 2012, online index operations and, also could be tracked by the extended event progress_report_online_index_operation. Troubleshoot Runaway Queries in SQL 2014 Using sys.dm_exec_query_profilesĪdditional notes for online index operations In fact, you can troubleshoot almost any query with this functionality, see this great post from by Carolina Vargas. Review the details of the sys.dm_exec_query_profiles and look for other interesting columns such as open_time, logical_read_count, write_page_count, first_active_time, last_active_time and more. Keep in mind that the output of the DMV is based on the execution plan generated by SQL Server, consider that the statistics are very important in the estimation of the retrieved records and that the order of the operations are determined by the execution plan too. Then you can view the progress of the CREATE INDEX statement and by doing so you can estimate the completion time under an equal base line of operation. SUM(estimate_row_count) AS estimate_row_count,ĬAST(SUM(row_count)*100 AS float)/SUM(estimate_row_count) as estimate_percent_complete Inserts rows from its input into the clustered indexįor example, the TABLE SCAN operator is being processed in 4 threads the estimated_row_count are the estimated rows to be processed and the row_count is the number of rows that were processed.
Retrieves all rows from the table specified. The result is the way on how the CREATE INDEX is being processed. SELECT session_id, request_id, physical_operator_name, node_id,
Sys.dm_exec_query_profiles will give you statistical information of the progress of every operator in the execution plan and if the plan executes in parallel then it will give you the statistical information by thread. On a different session execute the DMV sys.dm_exec_query_profiles While this session is executing the CREATE INDEX command you can monitor the execution with sys.dm_exec_requests and sys.dm_os_waiting_tasks and the progress with sys.dm_exec_query_profilesģ. Execute the CREATE INDEX command SET STATISTICS PROFILE ONĬREATE CLUSTERED INDEX cix_SalesOrderDetail_demo_soid ON (SalesOrderDetailID) Change the session behavior by enabling SET STATISTICS PROFILE ONĢ.

One of the challenges for DBA's are to work on heavy load and critical systems where maintenance windows are usually very short, recently I was asked for a customer if there was any possibility to track or estimate the progress of a CREATE INDEX statement and my response was sys.dm_exec_query_profiles.
