Runnable Master Awaiting Command
Nov 1, 2006
Hi,
Database Server running slow. I used SP_WHO2 ACTIVE and the result
has many of
XXXX SA RUNNABLE MASTER AWAITING
COMMAND..........
(XXXX is spid)
and they stay for couples seconds.
Last week , the server was running fine and during weekend ,none
of errors record in Windows
event log or SQL Server log.
Server is Windows 2003 server with 4 CPUs of xeon , 4 GB of memory
and
MSSQL SERVER 200 SP4.
I found out that every runnable master db tasks has shared lock on
key of
'master.dbo.sysxlogins.sysxlogins' object
Is this the problem of slow running database server?
Please advice.

I am using SQL Server 2000. In Enterprise Mgr, under Management/CurrentActivity, I see a list SPIDs.I have a multi-tiered .NET web app that uses ADO.NET to connect to thedatabase. Each time a Stored Proc is called, a new connection is opened, thedata retreieved, and the connection closed and set to Nothing (in VB.NET).Yet, I see several (15 or so) SPIDs for the user ID that the web app uses toconnect to the database.The database is local and private, so I know all connections are from me.What does Status=SLEEPING Command=Waiting Command mean?What will happen when we get 1000's users on the web app?Is SQL doing some kind of connection pooling?

I am debugging an app which blocks many processes in a SQL7 server DB.The app log writes every transaction "open" and "close".The weird thing is : when the app logfile says the transaction isdropped (object closed) the db keeps showing the process "running", ina sleeping mode, with open_tran in 2 or even 3 and in an awaitingcommand status.We are working on NT4.0, SP6a (all fixes up to date, MDAC 2.7SP1) onIIS side, an equal box for MTS (same patches and updates) and a SQLServer 7 (on NT4, same fixes ans SPs) database on another box.Is this normal? Those sleeping processes are blocking other apps andeverything gets slow and messy....the only solution is to kill thoseblocking processes.Thanks!

During our DR drill we found that the same code which used to run perfectly fine on our Primary Data Centre is running very slow on Disaster Recovery DB Server and there are Lot's of open transaction with sleeping status and waittype as 'AWAITING COMMAND'.CPU, Memory and disk utilization are good. The ping reply between the app server and the DB server is well within the limit's even blocking is not their, also nothing is reported in the error logs. We are using SQL server 2014 STD 64 BIT on Windows Server 2012.

In a development database, a developer was running 11 simultaneous jobs (in
PB) doing inserts into 11 tables. Ten completed and he wanted to know which
one was still active. We suspected it was on the largest table with the
most inserts was the one still active.
We're running on MSSQL 6.5, sp4.
We looked at current activity -user activity and saw that there were two
active users. Myself and someone else but not the developer. Although one
hint was a small blue line in the icon of a red page surrounded by a red
circle and a red line going through it, I guess that was the indication of
which table.
When we logged onto ISQLW and ran sp_who on are separate machines as sa, we
saw different statuses on the same process.
I saw the process 31 as sleeping and the developer on his machine(also
logged on as sa) saw the process 31 as runnable?
My question is this correct? How do I tell if HIS process is running if I
can't see it on my machine when we are both logged on as SA?
Any help will be greatly appreciated. Thanks.

Hi there,
Currently using SQL Server 2000 (SP4). The following condition started occurring last week:
- Server has excessive blocking
- Majority of the processes are in runnable state
- Excessive blocking happens for a few mins. and repeats again during the day. Does not happen at night.
- Nothing on the server errorlog, profiler
- CPU averages 40 - 50% at that point of excessive blocking
Any help would be greatly appreciated.
Thanks.

Hello all,I'm using SS 2000 and NT4 (and Access97 as front-end on another server)Well, probably by lack of knowledge about table locks, I don't really knowwhere to start to present this problem. In Enterprise manager, section"Management->Current activity->Locks/Objects", we have a couple (5-7) of"forever runnable" processes, all related to two specific situations. Eachof them are for "SELECT" statements. It's been a long time since it's likethat. I've always been curious about them but the weren't causing anyproblem. Now, after a modification, a third situation happened ("SELECT"again)... and sometime a lock created by this new "forever runnable" processblocks other functions that use the same table. All my table are linked withan ODBC link.Any help or suggestion where to search would be appreciated.Thanks.Yannick

I got a File with sales orders and their details.
Step 1. First I am filtering the Sales Order information and inserting it in my Sales Orders table.
Step 2.Then I am filtering the details from the sales Order and inserting them in the respective table.
My Problem is that the Sales Order File does not contain the Sales Order key (ID), this is generated by the SQL Server. How can get it in order to use it in the second step? I need it because it is a foreign key in the details table.
Any Idea?

Hi All,
i am using a OLE DB Source in my dataflow component and want to select rows from the source based on the Name I enter during execution time. I have created two variables,
enterName - String packageLevel (will store the name I enter)
myVar - String packageLevel. (to store the query)
I am assigning this query to the myVar variable, "Select * from db.Users where (UsrName = " + @[User::enterName] + " )"
Now in the OLE Db source, I have selected as Sql Command from Variable, and I am getting the variable, enterName,. I select that and when I click on OK am getting this error.
Error at Data Flow Task [OLE DB Source [1]]: An OLE DB error has occurred. Error code: 0x80040E0C.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E0C Description: "Command text was not set for the command object.".
Can Someone guide me whr am going wrong?
myVar variable, i have set the ExecuteAsExpression Property to true too.
Please let me know where am going wrong?
Thanks in advance.

Hello,
I'm new to SQL and need help with a query. Not sure if this is the right place.
I have 2 tables, one MASTER and one DETAIL.
The MASTER table has a masterID, name and the DETAIL table has a detailID, masterID, and value columns.
I want to return a populated MASTER table with entries based on the DETAIL.value.
SELECT MASTER.*
FROM MASTER
WHERE DETAIL.value > 3
This is a simplified version of my problem. I can't figure out how to set the relationship between MASTER.masterID and DETAIL.masterID. If I do an INNER JOIN, the number of results are based on the number of DETAIL entries. I only want one entry per MASTER entry.
Hope this makes sense.
How can I do this?

if i want to create a database, using:
CREATE DATABASE name
does it need the USE MASTER before the line? a database MUST be created using Master??
i ask this because in an example i need to create a database, so i use the next code:
CREATE DATABASE Banco
ON
(NAME='P_Banco',FILENAME='C:Documents and SettingsVictorEscritorioBancoP_Banco.mdf')
LOG ON
(NAME='P_Banco_Log',FILENAME='C:Documents and SettingsVictorEscritorioBancoP_Banco_Log.ldf')
USE Banco <-- i wrote this, because i tought i could create tables and stuff directly in my previously declared database, but it sends this error:
"Could not locate entry in sysdatabases for database 'Banco'. No entry found with that name. Make sure that the name is entered correctly."
anyway, i could do it, but first creating the database, and after that, in a separate code creating the tables with USE Banco, but my question is..why is that? or i miss something in my sql code??

Hi Friends ...
I need your advice and help on the following problem . Say for example I have a SQL 7.0 Server A with 30 databases and i am in the process of transfering these databases to another system which is SQL Server B with 7.0 again .
Although the Databases can be copied by various means , can i restore Master database from the Server A to Server B so that my Server B will have all the database and login information as that of Server A.
As Master database is system database , it won't allow to be dropped and hence you cannot restore .
Is there any other way to restore Master database from One SQL server 7.0 to another with the same SQL version .
Any kind of assistance will be of great help to me . Many thanks in advance .
Kind Regards
Sneha

Hi folks,
In SQL 7 when you query
select name, crdate from sysdatabases where name like 'xxx3%'
You get a reply with the rows of matching databases in sysdatabases. But in SQL 2000 the same command throws an error saying that the object sysdatabases is wrong. Here is the modified command
select name, crdate from master.dbo.sysdatabases where name like 'xxx3%'
Now my problem is I can include the latest piece of code and go further. But my older version of product will have this problem and will fail. Is there anyway that I can dothis on SQL 2000 to be compatible with my old product.
regards,
mahesh,

Hi,
I have a question regarding master database.I know if a master database is
corrupt we need to rebuild the master.One of the guys suggested us to
maintain a copy of master data file and log file in diffrent directory and
when master database is corrupt we can copy the files to the actual location
and restart the sql server and this should fix the issue and by this method we can save the time of rebuilding the master database.I don't know if this works.Can anyone please tell me if this works and also disadvantages if any with this method?
thanks

Various books read suggest that the Master
database be backed up when it is changed.'
What activities does a DBA perform (or perhaps)
a user) will cause the Master database to
change?
I am aware that information about the addition
of new databases is kept in the Master.

hi, What are the symptoms that the master database is currepted?
If I do not know the databases sort order, code page, and Unicode collation and I had a master database crash, it is important during the rebuild process to maintain same configuration,
Is there a way to run a script which tells me the configuration set up of the master database. so I know ahead of time what configurations Ican use during the rebuilding process.
