we are working on a release 2.0 mobile solution right now. In our version 1.0 we did not have to worry about memory issues as our application was the only application running on our target devices (e.g. T-Mobile MDA Compact II Pocket PCs, WM2005).
Now we need to share the available memory with others. As our application relies on its SQL Server 2005 Mobile Edition database we are wondering about memory usage of that server.
We know that a Pocket PC divides its memory into Storage and Program. If our application uses a 5 MB database and 1.5 MB for DLLs and it's exe-file. These files reside in the storage space when not loaded. When the application starts up it is loaded in the program memory. What happens to the 5 MB database file? Is is loaded into Program memory as well? Are only portions of that file loaded? Or is nothing loaded at all?
Does anyone have a deeper insight into that server an can answer my questions.
Is there any way to measure bandwith usage during merge replication between sql server 2005 and sql server mobile 2005 running on a cradled wm5 mobile device.
Attaching the windows performance monitor to the network connection established over usb would work although I was wondering if there was something specific for this case integrated into Sql server 2005 / sql server mobile 2005 / Sql server management studio / third party tools that i could use ?
We have an application that we currently run on SQL Server 2000 that works by creating a DTS package that it then executes.
Due to performance reasons, we have been considering switching to 2005, for a few reasons. Can anyone confirm clarify the following?
1) SQL Server 2000 caps RAM usage at 2GB, whereas SQL Server 2005 is only limited by the OS - RAM usage is a big current issue for us, so if upgrading to 2005 would solve this it would help a lot. Can anyone confirm my understanding of this? 2) Would using the legacy DTS in SQL Server 2005 take advantage of this RAM difference, or is it running on the old 2000 engine and only able to use the 2GB?
When I try and connecto to SQL CE I always get an invalid operation exception. I"m afraid that I did not follow the proper install for Orcas Beta 2. I can't remember if I was supposed to uninstall SQL Mobile 2005 first or not.
All I know is when I try and use my SQL CE I can't connecto to a DB / sdf file ?
Any help would be appreciated I"m just starting to use SQL CE.
I am developing a mobile application in which i have to create a database..
My database contains relationships between its tables.. I would like to know what is the best solution for developing the database?? SQL mobile edition or RMS!!!
If you say RMS, how should i create the relationships between my tables??
I have some SQL CE database .sdf file on my handheld, and I was trying to connect to that file via SQL Server 2005 Management Studio, and it does not work. I am wondering if there is any good tool that I can use on desktop to connect to sqlce .sdf database file on my handheld?
I just want to display all the data of a Single table into a Data Grid, I know that we can drag and drop the table on to a form and datagrid is generated, but here I want to retrive those values through my code, how should i do that
I am getting following errors while running the program Error 1) Error No. 28037, MS SQL Server 2005 Evrywhere Edition Error: A request to send data to the computer running IIS has failed. For more information see HRESULT Error 2) Error No. 0, SQL Server 2005 Evrywhere Edition ADO.Net Data Provider Error: The specified table does not exist [ JobLists ].
Can anybody please tell me, where I went wrong ??? In this code anywhere else????
Note: While adding a Data Source of SQL Server 2005 Mobile Edition, I have added that .sdf file into my project, thats why I have written the Data Source as : .DbFile.sdf
@"Data Source = .DbDotNetCF.sdf";
The code is as follows:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Data.SqlServerCe;
namespace DeviceApplication1 { public partial class Form1 : Form { string filename = @".DbDotNetCF.sdf";
private DataSet dsJobLists;
public Form1() { InitializeComponent(); }
private void DeleteDB() { if (System.IO.File.Exists(filename)) { System.IO.File.Delete(filename); } }
private void Sync() { SqlCeReplication repl = new SqlCeReplication();
if (DbDotNetCFDataSetUtil.DesignerUtil.IsRunTime()) { // TODO: Delete this line of code to remove the default AutoFill for 'dbDotNetCFDataSet.JobLists'. this.jobListsTableAdapter.Fill(this.dbDotNetCFDataSet.JobLists); } } } }
I have created a merge replication correctlly( I suppose, there were no errros) Please help

I have a question: is the SQL Server 2005 mobile edition free? or is it necessary to buy a licence when i use it combinated with a comercial program which i have delevoped by myself and i sell it?
I am looking for a reporting software to create reports (Invoices, Receipts) for PocketPC 2003 using Visual Studio 2005 and SQL Server 2005 Mobile Edition. Any recommendations will be appreciated.
I want to create SQL server 2005 mobile database on desktop programmatically with some inital data for my application and load it into device. We can create database only in VS2005 server explorer or SQL server 2005 application.
Hi,i want to create a solution which shall consist of a sql server 2005 -data base (express edition if the following features are available byexpress edition) and a mobile windows application (running on asmartphone under windows mobile 5.0).The sql server shall be installed on a ordinary laptop using windowsxp (not professionall edition).Which would be the best way to exchange the data between mobile deviceand pc? I learned that there is a SQL Server Compact Edition for themobile device and that rda would be a way to exchange data - but theni would need internet information system and this does not run on xphome edition.Which alternatives would you suggest me?Thanx in advanceWolfgang
I was wondering if someone could help me as this is a bit of a puzzle.
I have created a database using a password, the create table scripts are executed successfully using the connection string however when I try and use the same connection string to insert some data into the database an error is produced, with the following message 'The specified password does not match the database password'.
I have opened the database using the SQL Server 2005 Management Studio and provide the password and I can access the database without a problem.
When the connection object is first instantiated all the Connection String property, the connStr variable and the modifiedConnStr are all correct (by this I mean that the data source and the password are present). However when the connection object is accessed again the Connection String property and the connStr variable are both set incorrectly (by this I mean that the password= section of the string is missing) however the modifiedConnStr is set correctly (by this I mean that the password= section is present in the string).
The connection object does not get set in between creating and accessing the connection object.
I have resorted to using no password, however I really need to be able to use a password.
Here is a copy of the connection string I am using (Copied directly from the quick watch window):
I am writing an application using VB.Net 2005 for the Windows CE 5.0 device and it is connecting to a SQL Server 2005 Mobile Edition Database. The trouble I'm having is establishing a connection to a SQL Server Mobile database on the device.
Here is the code I am using:
Code Snippet Public gConnectionString As String = "Data Source=Program FilesMobAppMobDB.sdf;Persist Security Info=False;"
Code Snippet
Imports System.Data.SqlServerCe
Public Class DBManager
Public Shared gSQLCEConnection As SqlCeConnection
Public Shared Function OpenDB() As Boolean
If gSQLCEConnection IsNot Nothing Then
Throw New InvalidOperationException("Connection already open.") End If gSQLCEConnection = New SqlCeConnection(gConnectionString) Try
gSQLCEConnection.Open() 'Error occurs here Return True Catch ex As SqlCeException
MsgBox(ex.Message & vbCrLf & ex.HResult & vbCrLf & ex.NativeError & vbCrLf & ex.Source) Return False End Try End Function
In the immediate window I recieve the following messages:
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll

A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
A first chance exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll
I believe that the first few lines are caused by the icons/pictures that I have included with my app, but the SqlCeException line occurs when the connection to the .SDF file is trying to be established.
Here is the exception output:
Message: "" (Blank) HResult: -2147024882 NativeError: 0 Source: SQL Server 2005 Mobile Edition ADO.NET Data Provider

Microsoft SQLCE 2.0 Microsoft SQLCE 2.0 Dev
Any ideas on what could be stopping this connection from being established? It was working before but all of a sudden just stopped. I have warm booted, cold booted, and rebuilt with no luck and also checked that SQL Query Analyzer is not running on the PDA and that the connection string is valid. The call to OpenDB occurs in the form_load of the startup object.
I am looking for a detailed tutorial that explains how to set-up merge replication services for a major project. I have seen all of the claims that SQL Mobile Server 2005 is able to connect to a merge publication with SQL Server 2000. However, where are the tutorials? I must have a proof of concept in a few days to quote this project. Can anybody help with this issue? Thanks!
I'm having trouble finding the optimum memory settings for SQL Server 2005. I have 4 instances running on a macine with 8 dual-core processors and 18GB of RAM. I have tried the following memory settings so far:
No maximum - one instance used about 12GB of RAM so then the others struggled Maximum of 4GB each (2GB left for Windows) - meant that 3 instances could be using 1GB each and then another at 4GB and needing more whilst 9GB sat unused. Minimum of 2GB each - one instance would use up 10GB and then never give any back to the other instances.
I also find that setting a maximum then just causes a high amount of paging. What I would like to do is have each instance use a minimum amount, say 1GB, and then have each instance use a maximum of 13GB (3GB for other 3 instances running at a minimum level and 2GB for Windows). This 13GB should then be released and allocated to another instance when necessary, assuming it is no longer all being used. I do not want paging to occur if an instance reaches 13GB.
How do I go about configuring SQL Server to behave like this? Is it possible?
OVERVIEW I run a MS SQL DB and have 7GB of RAM allocated to it to use. My DB size is around 30GB. I have about 30-40 users at any given time accessing this DB, and on any given moment we may have 2-3 queries being processed at the exact same time, but not really a high rate of usage.
The SQL is running on a 2 - Dual Core Xeon 2.8Ghz processor server in RAID 1+0. The average CPU usage is around 8-15% at most times, spikes to 60-70% sometimes then drops back down.
QUESTION Why or what would cause SQL to show in my Task Manager as using 7GB of RAM constantly? When I restart SQL, system RAM drops to 1.7GB and holds. As traffic increases, as queries begin to be processed in SQL the RAM rises till it reaches the 7GB limit I set. Before it reaches this limit, the ASPX pages run smooth as silk. Once it reaches this 7GB limit they begin to crawl. A process that would take 2-6 seconds, now takes 30-60 seconds.
I know a couple years back I ran into this and it was because processes were not being closed and SQL was holding them in RAM, but I have been assured this is not the case now. I was told that because my DB is 30GB total (MANY tables, most are hardly ever accessed, and the bulk of the data is hardly accessed) that it is common for SQL to use and hold on to 7GB of data - is this true?
What would cause SQL to hold 7GB and slow way down? IS there a KB article that could help me understand this?
I have a three-tier app written in C#, which takes information from a third party source (typically an array of double precision floats) and commits it to a SQL 2005 Db.
The Server then notifies the client that the information is available and the client queries the Db (through the server) in order to display it in "real-time". It all seems to work fine except that the memory usage by SQL 2005 just keeps rising. I have run a memory profiler on the server and client apps and they do not have a leak.
The test I am running has all three apps on the same machine and is reading in about 250k of data a second. It typically runs for just under two days on a machine with 2Gb RAM before falling over with System.OutOfMemoryException.
I have tried setting max memory usage but it seems to make no difference... anyone seen anything similar or know what my problem might be?
We recently did an in-place upgrade of our cluster from SQL 2000 Enterprise to 2005 Enterprise. We are seeing memory utilization on the server that is not expected and wanted to get an idea from others if this is normal. Here is our setup:
32-bit Windows Server 2003 SP1 SQL 2005 SP2, 2-node cluster 16 GB memory on each node /3GB /PAE switches in the boot.ini file AWE Enabled, min memory=0, max memory=14000
The strange bit is that in the Task Manager the SQL service is showing as only using 205 MB of memory and the pagefile usage is at 13 GB. This is troublesome since it looks like SQL is using virtual memory instead of physical memory. We recently upgraded the memory from 4 GB to 16 GB, the sql cluster service account was added to the Lock Pages in Memory policy, the boot.ini switches were set and the AWE enabled/max_server_memory script was run before upgrading to 2005. Can anyone confirm either 1) this is normal or 2) how to correct the memory usage?
I have also questioned using the /3GB switch; would it be better to remove that and set the max memory for SQL to 12000?
Any help would be greatly appreciated. If I left off any information that would be helpful, please let me know.
We have only a small busines and haven't got too much experience with servers and now have a proliant server coming in with SBS 2003 R2 Premium with the 4 GB max memory that SBS 2003 can handle according to the specs.
We weren't planning on using the SQL 2005 worlgroup edition up till now, but now we might. According to the specs of SQL server 2005 workgroup edition however, it has a max RAM of 3GB!
Is this going to be a problem and should we keep using our previous DB, or can we migrate toward SQL server with the 4 GB of RAM?
I'm hoping that some might have an answer for me after much net searching.
I have a server (200GB disk space, Dual 3.8 GHZ processors, 4GB memory) that hosts 6, very small, SharePoint sites (WSS 2.0) and SQL 2005 express handling 1 config DB and 7 content DB's. The biggest DB at the moment is only 300 MB and the sites are not actively being used yet, they are only open to a select number of users (+ - 25 in total) who are using them as reference "areas" at the moment. Each site is running in it's own application pool as well.
I find that the sqlserv.exe process increases in memory usage and does not seem to decrease. It gets to the point of 960 MB usage and then databases cannot be used (SQL 2005 Express max memory is 1GB). SQL seems to "close" them down and site errors being received are "site is not in configuration database". When the SQL service is restarted the memory usage idles around 70 - 80 MB, the sites are 100% again but after an hour or 2 the memory usage is sitting at 560 MB again and doesn't seem to decrease.
Is there a way I can bring this memory usage down?
I have a client program that writes to sql server database 10 records per second . i want to compute the CPU usage and the memory usage for the whole program or CPU usage,memory usage for the insert statement in the program .
One of the production box running only sql server application, is showing 80% memory usage on the task manager-memory usage history right now.
We are running sql server 2000 standard version-sp3 with 2GB memory on this box. Server is not on the scheduled reboot at this point.
We have seen this behavior for this box last month that after task manager showing 90% memory usage contantly for several days, when server was manually rebooted, memory usage dropped to 35%. Now it's back to 80%.
Our DBA thinks that server should be rebooted on a regular schedule regardless of memory problem. Our network admin doesn't seem to agree with this. He is not ready to reboot the machine even with this high memory usage.
There is no noticable difference performancewise yet.
My questions are: Is it bad that memory usage reaches from 35% constant to 80-90% or is it common? Should sql server be rebooted immediately to take care of it? Should sql server 2000 rebooted on regular basis regardless of any problems? Shouldn't sql server be releasing memory back to the OS even without rebooting? How do I find out whether server actually is going through memory problems and what is causing it?
Currently I have an application that uses SQL 2000. The SQL server service tends to take up as much of the physical memory as possible. The problem is I also have other services relating to this application running that are very important.
What tends to happen after a period of time is SQL takes up all of the physical memory, so that the other services are using the paging file (virtual memory). This causes extremely slow response time over the network as these other services are having to parse the paging file.
Upgrading the memory is currently not an option :(
I know there is an option to set memory usage for SQL but I am unsure how this would respond in a production environment. What would happen if SQL would require more memory than what was allocated to it?
Can SQL release the memory and still act as normal?
