capture SQL job running metrics and store into below physical table (day by day), (this table contains last 60 days data).
Purpose : fetching a job which is taking longtime to run ( by comparing avg running time - like standard deviation ).
below FactLoadCubeProcess sqljob contains 9 steps,
StepDurHHMMSS column value = HH:MM:SS ( 11455 means 1:14:55 )
Need a query to find which SQL job taking long time compare to previous avg time...
Jobname,stepname,date,durationrunning, avgrunning
I am using the SQL Server 2016 - "Always Encrypted" feature locally. Currently I am using Self Signed Certificate and creating the certificate using powershell command.
$cert1 = New-SelfSignedCertificate -Subject "ABC210902" -CertStoreLocation Cert:LocalMachine\My -KeyExportPolicy Exportable -Type DocumentEncryptionCert -KeyUsage DataEncipherment -KeySpec KeyExchange
Now I want to plan for production, and I assume we need get the certificate from a CA authority. Can you please guide me as what type of certificate should we purchase and what additional features the certificate must have to make it a Master Key Certificate?
Not able to generate Self Signed Cert in Windows Server 2012 R2 using Powershell for SQL Always Encrypted. I have SQL Server 2016 installed.
The options for New-SelfSignedCertificate command in Powershell, is very less in Windows Server 2012 R2
We don't get the ---- -KeyExportPolicy Exportable -Type DocumentEncryptionCert -KeyUsage DataEncipherment
I'm trying to create a link server with the new MSOLEDBSQL provider, to make use of the MULTISUBNETFAILOVER options, but all attempts to create one regardless of SQL Version results in "Microsoft Distributed Transaction Coordinator (MS DTC) has stopped this transaction." errors. Are there any fixes for this yet?
One SQL 2016 prod database VM is being used by users for querying data, analytics, reporting, etc. users are in same domain and not using SSL. However, one database in another data center will query regularly one of the database on this first server. In order to use SSL, I can configure self-signed cert to protect communications between db servers in these 2 data centers.
AFAIK, if I force encryption on the instance, just encrypted connections are allowed, which is not what I need. or I need to separate this database into a separate instance just for this. I do not have a spare dev where to test this.
Can I enable SSL encryption that will be used by the remote server only, while regular users will not use SSL on same instance?
Thank you,
What is the best way to import from Oracle DMP into SQL Server 2012?

Dear All,
Whenever I try to send any mail from SQL server via any jobs or maintaience plan, mail is going to queue without sending . Any help regarding this will be highly appreciated. I am using SQL server 2016 Standard Editions with SP2 and CU3 installed .
All,
I'll start with the fact that I am not the "SQL Guy" or a SQL DBA. I'm working on a new client's backups and found that they have a Windows Server 2008 R2 server running SQL Server 2008 R2 Standard that hosts a SharePoint DB. This server stopped backing up a few days ago and it appears the server is out of available overhead for VSS to complete snapshots.
Additionally, the SQL DBs hosted on this server appear to not have been backed up since mid 2015. This is due to the SharePoint DB's LDF being ~214 GB. The MDF itself is only 650MB and it appears their original SQL maintenance plan had not been configured correctly to complete the log truncation.
After discussions with the client, they do not require point in time recovery but do have some concerns with a switch to Simple Recovery. As I'm not versed in SQL, I'm looking for some input. Below is what we're trying to gauge.
1.) How long would SQL take to flip the DB from Full to Simple Recovery Model with such a large LDF? (The client is a 24/7 shop and requires a high level of uptime and strict outage windows).
2.) Once the Full to Simple Recovery operation has been initialized, can it be stopped without any detrimental effects to the production DB? (They pose this question in the event the process time is determined to be excessive) My gut says it would be similar to terminating a CHKDSK operation on a NTFS volume, you never stop it once it's started, unless you want to risk data loss or corruption.
Below are the full specifics for the server and SQL:
===========================
Server: Windows Server 2008 R2
SQL: SQL Server 2008 R2 Standard RTM (10.50.1600.1)
Database: 650MB MDF / 214GB LDF
============================
Any and all help is greatly appreciated and thank you for your time.
I have many SQL Server Agents Jobs. Many were scheduled at the same time. Say 1:00 am. In the schedule lists they are duplicates. I want to delete most of them and just keep one and then I want those Agent jobs to share the schedule if these jobs are going be scheduled at that time.
How can I delete these schedules? Thanks.
May I know what's the limit of the max worker thread ?
suppose have have 8 processors
then I set max worker thread to 32,767
so the max thread should be 576 or 32,767 ??

Hello,
I have a 500M rows table on which I want to create a filtered index containing rows of the last year. Every month I want to recreate the index (with drop_existing = on) dropping one month from it.
I expected this would be very fast, as it only needs to remove rows from the front of an existing index. No sorting and no need to read all the data.
My experiments show however that the clustered index is scanned, all rows are read, and an expensive sort is done.
Even when I create a new filtered index that is more restrictive than the existing, still all rows from the clustered index are read and sorting is done. Why is the existing filtered index not used, even though it contains all the data in the right order?
Curious to hear. Thanks
