hi all:

  I understand If your database has virtual log files (VLFs) larger than 4GB then do not use backup compression with TDE for your log backups. 

Here is the situation. I have a  database and they VLF size is over 20G. But active VLF size is around 60MB

Total of VLF count is 244 but inactive VLF is 243. 

questions:

1. Can I use backup compression with TDE for this DB (VLF size over 20G but active VLF size is 60MB? 

2. What is the consequence of using backup compresison with TDE for DB with active VLF size over 4GB? 

thanks

 Hui

Hi Everyone!

I have a PROJECT database

The drive that contains the PROJECT database is deleted from the virtual machine.

So, when i trying delete or detech the PROJECT database on SQL Server Management Studio error: 

The operating system returned error 21(The device is not ready.) to SQL Server during a read at offset 0x00000000836000 in file 'D:\Data\PROJECT.MDF'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online. (.Net SqlClient Data Provider)

Please guide me delete or detech this database on SQL Server Management Studio

Thank!

I am trying to understand the memory management of SQL Server. I have a Windows Server 2019 on virtual environment with 64 GB of RAM. I also have SQL Server 2019 installed with Max Server Memory 59776 MB. By using the following query I found the list of all memory clerks:

SELECT  [type] AS [ClerkType], SUM(pages_kb) / 1024 AS [SizeMb]
FROM sys.dm_os_memory_clerks WITH (NOLOCK)
GROUP BY [type]
ORDER BY SUM(pages_kb) DESC

Total sum of all memory clerks was equal to 23523 MB.

Value for MEMORYCLERK_SQLBUFFERPOOL memory clerk is 18387 MB.

I also checked some performance counters:

Total Server Memory (KB) = 32262 MB.
Database Cache Memory (KB) = 18387 MB.

Please correct me if any of the below statements are wrong,

Max Server Memory for SQL Server 2019 = Buffer Pool Memory + Non-Buffer Pool Memory.

Total Server Memory (KB) - The committed memory from the Buffer Pool.

Data Cache Memory (KB) performance counter is equivalent to MEMORYCLERK_SQLBUFFERPOOL memory clerk and both represents data cache used size.

Above query shows all memory clerks for both Buffer Pool Memory and Non-Buffer Pool Memory.

My question related to this subject:

If Total Server Memeory (KB) is related to Buffer Pool memory, then why its size (32262 MB) is bigger than Total sum memory clerks altogether (23523 MB) which represents both Buffer Poll Memory and Non-Buffer Pool Memory?

EDIT: Result of select * from sys.dm_os_process_memory

physical_memory_in_use_kb = 38065556

large_page_allocations_kb = 333824

locked_page_allocations_kb = 37424380

I have setup linked servers on my SQL Server and choose Oracle as a linked server.

SOMETIMES, When I run the query below under the SA username, I get different result. However when I run under my own username I get correct result. I Can't understand this anomaly. The below query returns only one row. The difference occurs in ORGANIZATION_FULL_NAME column only.

Hi Experts,

Is there a way to assign resources , memory/cpu to individual database so if an instance is assigned 32 gb , out of 10 databases on that instance , assign 4 gb and 1 vcore to one of the databases.

Thanks

Has anyone experienced an error 9019 on SQL Server 2019? This error occurred on the forwarder in a distributed availability group configuration. Nothing was connected or executing anything against this instance, but index maintenance was executing against the primary node of the primary availability group. 

There are no indications that the replication of data got behind and the health of all of the AGs is good. 

I can see that the 9019 error was an issue corrected in SQL2012, but this one seems to be different.

SQL Server 2019 CU3 (15.0.4023.6) Enterprise Edition

Government sites on AWS, because they are more Linux shops than Microsoft shops, block the Log On As A Service.

Are there alternative methods for service accounts where "Log On As A Service" is not a requirement?

Hello,

I'm not sure how to go about planning database growth over a 2 year span.

My sys admin is asking me to for resource needs ( memory, disk , cpu) and I'm not sure how to go about this.

Please advise.

Hello, 

We have MS SQL server 2016 Enterprise (SP2-CU5). After starting the server, the default trace file grows to 20 MB, and then stops with this error in ErrorLog:

Trace ID '1' was stopped because of an error. Cause: 0x80070057(The parameter is incorrect.). Restart the trace after correcting the problem.

Error: 19099, Severity: 16, State: 1.

sys.traces is empty and sp_configure "default trace enabled" config_value and run_value is 1.

Any thoughts how to solve this?

hi we run 2014 std.  we have 2 dbs (staging and warehouse) that are always on the same server and we often reference both in certain procs.  the procs are always on staging.

in order to have multiple environments set up for development purposes,  i'll often combine the tables from each (staging and warehouse) in one local db, call it x.  and simulate real life by not qualifying queries targeted for staging but prefixing queries going to warehouse with x.dbo....

for my testing to be more valid i'd like a way for the x to be "mappable" by a parameter or something as i move thru the dev, qa and prod environments so that the x is "soft replaced" by the word warehouse.

is there a way to do this?

Hi 

Version :2014

We have database and gone in to RESTORING stage,. Our backups are Veam and backup run as  their technology snapshot. what ever the status of the database datafiles MDF,LDF will backup. Backup software not aware status of the DB.  now when I restore the backup files(through Veam backup software), I am unable to open the database even with data lost. Any one can advice how to open the DB.

RESTORE DATABASE database  WITH RECOVERY;

hi ,

table : dispalytable      ( heavy transaction table)

 a  query gave result set .    select top(1) * from dispalytable where id >10

user1  ran that  query 

user2  ran that  query

but i want to restrict the first record not displayed to  second user , the second user2 only can view nxt top first record of the result set.

( no user can view the same result set)

how to accomplish this ?     ROWLOCK ?

An error occurred while processing the log for database 'tempdb'.  If possible, restore from backup. If a backup is not available, it might be necessary to rebuild the log.
During undoing of a logged operation in database 'tempdb', an error occurred at log record ID (239:1702646:104). Typically, the specific failure is logged previously as an error in the Windows Event Log service. Restore the database or file from a backup, or repair the database.

SQL Server must shut down in order to recover a database (database ID 2). The database is either a user database that could not be shut down or a system database. Restart SQL Server. If the database fails to recover after another startup, repair or restore the database.

------

After these messages, i had to start SQL services manually, however the errors continued

Error while allocating extent for a worktable.  Extent (6:16248) in TEMPDB may have been lost.

-------

I ran DBCC CHECKDB(tempdb)  --- no results.....

Checked with storage team for health checks, they say no issue.

However, i see many suspect_pages recorded for this DB and it even got recorded before the server crash too.

then i had to manually delete the tempdb files and restart SQL services. Errors stopped and DB health is OK.

Trying to investigate the root cause, any pointers/advise is really appreciable. Thanks in advance.
