Database Engine fails to install

August 10, 2019, 1:57 pm

I have a full version developer 2017 and version 18 ssms as well as SSDT 15 installed already.  This would be for a side by side (SXS) of SQL 2019 CTP 3.2 running on Win10 (plenty of RAM 24 GIG - dual hex CPU)

 The error above comes along with two others:

1) Unable to open the Server service performance object. The first four bytes (DWORD) of the Data section contains the status code.
2) The Open Procedure for service "WmiApRpl" in DLL "C:\Windows\system32\wbem\wmiaprpl.dll" failed.
3) The Open Procedure for service "Lsa" in DLL "C:\Windows\System32\Secur32.dll" failed.

These occur while installing the SQL Server 2019 CTP 3.2 Database Engine only.   150 Folder installs and repairs - only the engine will not install.

The suggested fix is to uninstall and reinstall - which I have done.

Ten seconds prior (again event log)

I have two systems , one using MS SQL and the other one using mySQL and so am using a linked server with OPENQUERY on MS SQL to connect to mySQL and read data from mySQL Database. The query works 100% on SSMS "SELECT * FROM OPENQUERY(MYSQL,'SELECT * FROM Transaction')" but if I use the same query on SSRS datasets, I am getting the error message below. Any ideas how I can fix this error?

Grant permission using sql procedure

Hi everybody,

I have a SQL database with 2 tables, which are updated every day at 9 am. I created new user, which has access only to those tables. Update process firstly drops, then creates new one. I tried granting permission for user to read these tables. However, after procedure run, user can't see them. How can I dynamicly grant permission or update content of table without dropping it?

Tables have same name as before, but I suppose, that permission is assigned by id.

Regards,

I have a SQL Server job that runs a SSISDB package. The package does some SQL database connection and creates an excelt file as output. Finally it runs a VB 2015 script that opens the created excel file and rcopies sheets from that to another excel file and then a macro is run. The jobs runs fine as a SQL server agent job while I'm still logged onto the server . However when I log out the VB Script task fails with the message ' Script Task Error: Exception has been thrown by the target of an invocation. '.

Hi we run 2017 standard.  What is the minimum permission(s) our dba needs to give me in order to run checkpoint followed by dbcc dropcleanbuffers on a dev server?  I have already read the do's and donts and have actually used dropcleanbuffers in the past at other sites.  I can already read tables etc on most of the db's on the targeted server.

the error I get is

Hi er run 2017 standard.  Our prod tables are replicated to a test environment. I've heard different things about replication including (maybe) the requirement for a primary key.  Are there any gotchas in a replication relationship?  Especially on the source tables in terms of performance issues, constraints etc?  I heard a rumor that deadlocks can occur when sql server replication is happening.

SQL 2016: Syscommittab - Cleanup Single Transaction Results in significant log run up.

May 13, 2019, 9:46 am
$

Good Morning All,

Question: Alternate ways to cleanup syscommittab.

Situation:
An abused Change Tracking implementation established pre version upgrade and patching to (13.0.5233.0) and upon removing high transaction side-table resulted in several billion record delete, single transaction upon sys.syscommittab.

Specifically after discontinuing change tracking on the most egregious offending dataset (tens of millions of transactions daily) we found log runup to the order of a terabyte per billion records in sys.syscommittab.  I believe this is a product glitch in how the table is cleaned up and was looking for suggestions beyond what is outlined in cleaning up the side table (e.g. discontinuing change tracking on the offender essentially drops the side table hence no need to clean it up.  Should not side table are the "sys.change_tracking_ObjectID" tables.).

We were contemplating purging in an organized fashion (not in a single transaction as the system was doing but rather in reasonable chunks) directly the sys.syscommittab table.  Specifically we would target records beyond the retention period.  This is after we have performed side-table cleanup such as outlined in https://blogs.msdn.microsoft.com/sql_server_team/change-tracking-cleanup-part-1/.

To add to my question above, has anyone attempted this and if not any thought on what we might expect would be helpful.

Version: SQL Server 2016 Standard SP2 CU4 (13.0.5233.0)
Logging: Full and Mirrored.

Log runup problem has been mentioned numerous times in this and other forums.  It wasn't until we had a very large log run up event that we started to dig to diagnose the problem.

Compounding Symptoms: Checkpoint blocked by "Task Scheduler" which was actually performing the syscommittab cleanup and "CtCleanupTblMetadata".  The process that drove up a pair of log files to their maximum, approximately 4.1 terabytes, then rolled back.   We couldn't add on additional log files to the database to mitigate the 2TB limit per file due to checkpoint being blocked by the syscommittab process.

Thank you in advance for any assistance.

After we enabled Change Tracking, we keep getting the alert below:

"Change Tracking autocleanup is blocked on side table of "tablename". If the failure persists, check whether the table "tablename is blocked by any process."

So we followed this KB article to set Trace Flag 8293, but still we get the alert (11 within one minute), anything we could be missing?

Performance issues using SQL CLR - High PAGEIOLATCH_SH

Dear community, 

let me describe my problem: 

Query: 

SELECT t.value1, t.value2, x.valueA

from My300GBTable t

CROSS APPLY MyTableValuedFunction(varbinary field from table t) x

Usually, this works fine. But in some cases the plan generation takes >30 minutes. The system is showing 0% CPU, 3mb/s disk read and low memory pressure (~700GB available). IO System is 72 disk array. Disk queue length on logical disk is around 1.

dm_exec_session_wait_stats shows high PAGEIOLATCH_SH for the session. 

Once the plan is ready, queries are running fast.

Any ideas how to troubleshoot that?

non clustered index with pk vs non clustered index without pk

Hi we run 2017 standard. I'm looking at some tables whose non clustered (nc) indexes are definitely being utilized in the execution plan but there is no pk and no clustered index.

Does an nc index perform as well on a table that doesn't have a pk?  Say in comparison with everything being equal except that the second table has a pk that is the clustered index?

looking for a technique to make date range joins perform better

August 13, 2019, 1:22 pm
$

Hi we run 2017 standard.  I've come across this challenge in the past but never solicited help on the matter.

Often, I come across situations where individual records in table A match only a SINGLE record in table B based on
a datetime range in table B that covers a single datetime column from table A.  And indices dont seem capable of making
the match as efficient as other business scenarios where a datetime range isnt involved.

What do i mean? Lets say table A is the incident table (see index also) shown in the code block and it has 30.5 million
records that are newer (start datetime) than 2 years ago.  and about 27 million older than 2 years ago. 

And table B is the job table (see index also, notice no physical pk defined) shown in the code block and it has 3.3 million
records of which about 1.7 million jobs get a match as explained below.  I should mention that presently endtime is null on jobs that arent finished yet.

It would be great if the following query would run much faster than 8-10 minutes.  I suspect if the match criteria
involved only 1 or 2 column equivalents, it would.  But date ranges seem to perform poorly.  I verified that the indexes
shown in the code block are being used in the execution plan.   Now that I look at the NC on the jobs table, I have to admit that I don't know what we were thinking.

select count(*) from
(

SELECT
       inc.pk,
       inc.StartTime,
       inc.EndTime,

Hello Experts,

        We have SQL Server 2012 on Windows server 2012 Failover cluster(VM).  Few days back we have installed Anti virus on Cluster nodes and got the error SQLServerLogMgr::LogWriter: Operating system error 170(The requested resource is in use.) Later we removed antivirus on both nodes. After couple of days again we started getting the same error and sql services are goes to stopped state. And if i perform failover then sql services are starting . Then after couple of hours later again it went to stopped state with the same error. This happened quite frequently in Node2 but on Node 1 it is happening very rarely.  Both nodes has different service packs and Windows CU.

Initially we thought it could be AV and now we completely removed still we are facing the same issue. 

Please help me to solve this nightmare issue.
