SQL Server – Get Transaction Log Size and Log Space Used
Use the following T-SQL script to get the transaction log size and log space used of your database.
SELECT DB_NAME(database_id) AS DatabaseName ,
CAST(( total_log_size_in_bytes / 1048576.0 ) AS DECIMAL(10, 1))
AS TotalLogSizeMB ,
CAST(( used_log_space_in_bytes / 1048576.0 ) AS DECIMAL(10, 1))
AS LogSpaceUsedMB ,
CAST(used_log_space_in_percent AS DECIMAL(10, 1)) AS LogSpaceUsedPercent
FROM sys.dm_db_log_space_usage;
SQL Server – Pending Disk IO Count
Below is a script to see the number of pending disk IO. The ideal value is 0. This value indicates the number of pending I/Os that are waiting to be completed. Each scheduler has a list of pending I/Os that are checked to determine whether they have been completed every time there is a context switch. The count is incremented when the request is inserted. This count is decremented when the request is completed.
SELECT SUM(pending_disk_io_count) AS [Number of pending I/Os]
FROM sys.dm_os_schedulers
SQL Server – Check Constraint Status
Below is a script that you can use to check the constraint status of all your tables in the database.

WHEN OBJECTPROPERTY(CONSTID, 'CNSTISDISABLED') = 0 THEN 'ENABLED'
ELSE 'DISABLED'
END) AS STATUS,
OBJECT_NAME(CONSTID) AS CONSTRAINT_NAME,

SQL Server – Capturing Blocking Information (Enhanced SQL Script)
When the database that I’m handling was experiencing excessive blockings, below is the script I use too see what are being blocked and which stored procedure is the blocker. Blocking is when one connection needs access to a piece of data and has to wait for another connection’s lock to clear.
SELECT blocking.session_id AS blocking_session_id, blocked.session_id AS blocked_session_id , waitstats.wait_type AS blocking_resource , waitstats.wait_duration_ms , waitstats.resource_description , DB_NAME(tl.resource_database_id) AS DatabaseName, blocked_cache.text AS blocked_text , blocking_cache.text AS blocking_text FROM sys.dm_exec_connections AS blocking INNER JOIN sys.dm_exec_requests blocked ON blocking.session_id = blocked.blocking_session_id CROSS APPLY sys.dm_exec_sql_text(blocked.sql_handle) blocked_cache CROSS APPLY sys.dm_exec_sql_text(blocking.most_recent_sql_handle) blocking_cache INNER JOIN sys.dm_os_waiting_tasks waitstats ON waitstats.session_id = blocked.session_id INNER JOIN sys.dm_tran_locks tl ON tl.lock_owner_address = waitstats.resource_address WHERE waitstats.wait_duration_ms >= 2000
The above query is okay but we were able to enhanced the script by adding columns to see what objects that are being blocked. Below is the enhanced version of the script.
;WITH T1 AS ( SELECT blocking.session_id AS blocking_session_id , blocked.session_id AS blocked_session_id , waitstats.wait_type AS blocking_resource , waitstats.wait_duration_ms , waitstats.resource_description , DB_NAME(tl.resource_database_id) AS DatabaseName, blocked_cache.text AS blocked_text , blocking_cache.text AS blocking_text FROM sys.dm_exec_connections AS blocking INNER JOIN sys.dm_exec_requests blocked ON blocking.session_id = blocked.blocking_session_id CROSS APPLY sys.dm_exec_sql_text(blocked.sql_handle) blocked_cache CROSS APPLY sys.dm_exec_sql_text(blocking.most_recent_sql_handle) blocking_cache INNER JOIN sys.dm_os_waiting_tasks waitstats ON waitstats.session_id = blocked.session_id INNER JOIN sys.dm_tran_locks tl ON tl.lock_owner_address = waitstats.resource_address WHERE waitstats.wait_duration_ms >= 2000 ), T2A AS ( SELECT blocking_session_id, resource_description, CHARINDEX('hobtid', resource_description) AS StartPos, SUBSTRING(resource_description, CHARINDEX('hobtid', resource_description), LEN(resource_description)) AS StartText FROM T1 ), T2B AS ( SELECT blocking_session_id, resource_description, StartPos, StartText, SUBSTRING(StartText, 0, CHARINDEX(' ', StartText)) AS hotbid_text FROM T2A ), T2C AS ( SELECT blocking_session_id, resource_description, CAST(SUBSTRING(hotbid_text, CHARINDEX('=', hotbid_text)+1, LEN(hotbid_text)) AS BIGINT) AS hobt_id FROM T2B ), T2D AS ( SELECT T2C.blocking_session_id, T2C.resource_description, OBJECT_SCHEMA_NAME(object_id) AS schema_name, object_name(object_id) as object_name, object_id, partition_id, index_id, partition_number, p.hobt_id, rows FROM sys.partitions p INNER JOIN T2C ON p.hobt_id = T2C.hobt_id ) SELECT GETDATE() AS DateTimeCaptured, T1.blocking_session_id, T1.blocked_session_id, T1.blocking_resource, T1.wait_duration_ms, T1.resource_description, T1.DatabaseName, T1.blocking_text, T1.blocked_text, T2D.schema_name + '.' + T2D.object_name AS blocked_object_name, T2D.object_id AS blocked_object_id, T2D.index_id as blocked_index_id, i.name AS blocked_index_name, i.type_desc AS blocked_index_type FROM T1 INNER JOIN T2D ON T1.blocking_session_id = T2D.blocking_session_id AND T1.resource_description = T2D.resource_description INNER JOIN sys.indexes i ON i.object_id = T2D.object_id AND i.index_id = T2D.index_id

1) Asked the customer to stop the SQL Server Service. 2) Had the customer rename the actual files on disk with a "_old" suffix so that the sql server would not find them and have the db come up suspect. 3) Asked the customer to start the SQL Server Service. Once the server came back up we were able to delete the database. 4) Had the customer create a new database with the same name and location as the original database. Used the output from sysaltfiles to verify this. 5) Had the customer stop the SQL Server Service. 6) Had the customer rename these new database files by appending a "_new" on the end of the file. 7) Had the customer take the old database files with the "_old" suffix and changed them back to the original name. 8) Had the customer start the SQL Server Service. |

SQL Server AlwaysOn (patching/updates in SQL 2012)
AG on Standalone Instance
Patching steps:
Patch the secondary replica (B)
Bring the secondary replica online (will be new version)
Log the original synchronization configurations for each replica. Change the secondary replica and primary replica to “Synchronous Commit” mode, waiting for the secondary replica (B) to be “synchronized.”
This will ensure there is no data loss during failover.
You can check dashboard or dmv: dm_hadr_database_replica_states for the status
Issue a failover through SSMS or T-SQL to failover the AG to the secondary replica. So now the new primary is B, the new secondary is A
Patch the original primary replica (A)
Bring the original primary replica (A) online (will be new version )
Wait for A to become “Synchronized”
Failover the AG back to A
Change each replica’s synchronization mode to the original configurations you logged in step3.
Caveat list:
Before you patch, you can still keep automatic/manual failover setting no change. Just a reminder: if during patching time, primary is down, automatic failover may fail if the secondary hasn’t completed the patching.
If primary and secondary replicas are in multisubnet, your client may experience a little bit longer time of disconnection or timeout during failover.
Please do remember to switch back to your original synchronization mode.
AG on FCIs (Failover Cluster Instances)
FCI on AG deployment Example
Primary replica(A): FCI1
Node1 – active
Node2 - passive
Secondary Replica(B): FCI2
Node3 – active
Node4 - passive
Choose between one of the following two options:
Longer downtime, less steps
(FCI rolling patching).
Patching steps (basic):
Patch Node4
Move FCI2 from Node3 to Node4
Patch Node3
Move FCI2 from Node4 to Node3
Patch Node2
Move FCI1 from Node1 to Node2
Patch Node1
Move FCI1 from Node2 to Node1
Optimized downtime, more steps
(Leverage AG failover patching).
Patching steps (optimized):
Patch Node4
Move FCI2 from Node3 to Node4
Patch Node3
Move FCI2 from Node4 to Node3
Log the original synchronization configurations for each replica. Change the secondary replica and primary replica to “Synchronous Commit” mode, waiting for the secondary replica (B) to be “synchronized”.
Manually failover AG from FCI1 to FCI2 (now the new primary is on FCI2, the new secondary is on FCI1)
Patch Node2
Move FCI1 from Node1 to Node2
Patch Node1
Move FCI1 from Node2 to Node1
Manually failover AG from FCI2 back to FCI1
Change each replica’s synchronization mode to the original configurations you logged in step #5.
Caveat list:
** Please use basic patching steps if primary and secondary are on different data centers/subnets **
FCI rolling patch guarantees zero data lost
Use synchronous commit secondary on a high latency network would impact OLTP performance
AG failover cross subnets might cause up to 20 seconds delay on client first connections.
SQL Server – AlwaysON Availability Group Replica is Not Synchronizing (Error: 976, Severity: 14, State: 1.)
You can lose communication between the primary and secondary replicas for some reason.
There is a policy on SQL Server to check the data synchronization state of the database replica. The policy is in an unhealthy state when the data synchronization state is NOT SYNCHRONIZING or the state is not SYNCHRONIZED for the synchronous-commit database replica.
Based on SQL Server logs, I observed the following messages:
The target database, ‘YourDatabase’, is participating in an availability group and is currently not accessible for queries. Either data movement is suspended or the availability replica is not enabled for read access. To allow read-only access to this and other databases in the availability group, enable read access to one or more secondary availability replicas in the group. For more information, see the ALTER AVAILABILITY GROUP statement in SQL Server Books Online. (Microsoft SQL Server, Error: 976)
According to Technet, this issue can be caused by the following:
The availability replica might be disconnected.
The data movement might be suspended.
The database might not be accessible.
There might be a temporary delay issue due to network latency or the load on the primary or secondary replica.
Further information: https://technet.microsoft.com/en-us/library/hh245199.aspx
Resolution:
You can fix it, using the following T-SQL command to force the resume synchronization:
ALTER DATABASE YourDatabase SET HADR RESUME;
Or
Using SQL Server Management Studio
In Object Explorer, connect to the server instance that hosts the availability replica on which you want to resume a database, and expand the server tree.
Expand the AlwaysOn High Availability node and the Availability Groups node.
Expand the availability group.
Expand the Availability Databases node, right-click the database, and click Resume Data Movement.
In the Resume Data Movement dialog box, click OK.
