Technical concerns regarding SQL Databases

Hi Azure technical team.
We're looking into the possibility of using Azures hosting services for our existing database of music files. After speaking to a representative from the Sales Team we've agreed upon going for the S0 SQL Database with 10 DTU and 250 GB storage.
We would like to "just" change the hosting of our existing database to Azure, but before we can do that we need to find out if its possible to install any given program to the server or not. Our database is programmed in "Ruby on Rails"
(Linux, Apache, MySQL, PHP) and is secured through username and passwords.
Can any of you from the technical team help with clarifying this for us? Your sales team do not have the answers..

Hi tigerspring_1,
Based on your description, you want to know that if you can install any given programs in Azure environment, right?
Azure offers a range of preinstalled Operating Systems you can choose from, such as Windows Server and Linux. You can create your own virtual machine directly in the cloud by using an image that is provided in the Image Gallery of the Microsoft Azure. Also
you can use your own image or your own disk to create a virtual machine in Microsoft Azure.
Once instantiating a virtual machine image,
you can install any software your application needs to run. And you are responsible for patching, configuring and maintaining the operating system and other software within your virtual machine. For more details, please review this article:
Overview of Azure Virtual Machines.
Besides, you can deploy PHP-MySQL Website in Azure, for more information, please review the following links.
http://azure.microsoft.com/en-us/documentation/articles/web-sites-php-mysql-deploy-use-ftp/
http://www.sitepoint.com/php-mysql-windows-azure-getting-started-deploying-git/
For Azure issues, I would recommend you ask the question in the Microsoft Azure forums at
https://social.msdn.microsoft.com/forums/azure/en-US/home?category=windowsazureplatform
. It is appropriate and more experts will assist you.
Thanks,

Regarding SQL Database Initialization

Hello All,
I had an existing working version of LiveCycle on Server A which had two drives; A.1 and A.2. Do to space constraints we decided to move the Adobe LiveCycle ES2 folder from drive A.1 to A.2. We had not created anything so we werent worried about loosing any data. When it was installed on to drive A.1 it was runnning on the default MYSQL database that is created when you install using jboss turnkey. . But now we want to connect our jboss application to a SQL server database. I went ahead and walked through the documentation in order create the database and users. I also made the modicications to the XML files within jboss. The problem I am having is when I try to run the LiveCycle ES2 Database Initialization in the Configuration Manager, I get the following error:
From LCM.log:

Are there other files that I need to configure in order to switch the application from the default MYSQL to the new SQL Database? And is there any way for me to test the connection to the database before I attempt to initialize it.
Thanks in advance.

First and foremost you cannot use the XMLs which are part of turnkey JBoss directly.
You should discard adobe-ds.xml and mysql-ds.xml from <LiveCycle Root>/jboss/server/<server profile>/deploy and get hold of SQL Server specific adobe-ds.xml and mssql-ds.xml and then make necessary modifications w.r.t your SQL Server.
In addition to this you would have to modify login-config.xml as well to add an entry of application policy for MSSQL DB.
If you have performed all these steps and still issues are coming then the error could be because of any of the reasons mentioned below:
The XMLs that you have configured
The connection pools configured
Missing database driver jar
I would recommend the following:
1) Make sure driver jar for SQL Server (most probably sqljdbc.jar) exists in <LiveCycle Root>/jboss/server/<server profile>/lib directory
2) Ensure that you have modified the following XML files correctly:
adobe-ds.xml and mssql-ds.xml inside <LiveCycle Root>/jboss/server/<server profile>/deploy directory
login-config.xml inside <LiveCycle Root>/jboss/server/<server profile>/conf directory
3) Ensure that you have removed mysql-ds.xml from the <LiveCycle Root>/jboss/server/<server profile>/deploy directory
Try opening the XMLs in a browser to verify that they are modified correctly.
You won't find an option to test the connection in LCM.
Though you could try starting up your JBoss without any EARs and see if it is coming up without issues.

Concerns over switching between new Azure SQL Database Service Tiers

Windows Azure's new SQL Database
service tier pricing model will be put into effect in less than 12 months. We currently have SQL Databases on the Business and Web Edition pricing models.
We recently asked Azure Support a number of questions around the scalability and ability to switch between these tiers. The responses so far have been far from encouraging:
Q: If we exceed the criteria for a given tier (see http://msdn.microsoft.com/library/azure/dn741336.aspx), how will Azure respond? For example, if we are on the S1 service tier, and we exceed the maximum number of sessions (200), will any new sessions be
blocked until we manually increase the service tier? Or will you automatically move (and bill) us to/for the next tier level?
A: If you exceed the criteria of the existing tier, you shall be notified of performance issue like throttling. Users may experience slowness and blocking. There will not be any automatic upgrade.
Q: So to confirm, if we suddenly experience increased, unanticipated client activity overnight due to our web site becoming more popular, you will be blocking any user sessions over and above our performance level limit, until we manually make the transition
to the next level? Is there no “overdraft” facility/scalability in this respect? If this scenario took place within a short space of time, how would we have time to react? Simply blocking new sessions and preventing customers from using our site is not acceptable.
A: I’m sure you understand that SQL Azure database is a shared resource and hence we cap the resources for individual subscription so that a fair service is provided to all the concurrent users. If you feel that you cannot compromise on the user experience
then you shall think of an edition that best suits you. Please refer to the following document to best understand the throttling and its impact. http://social.technet.microsoft.com/wiki/contents/articles/1541.windows-azure-sql-database-connection-management.aspx#Throttling_Limits
Q: Since the changing of the performance level could take several minutes/hours depending on the size of the database, would we experience any downtime/degradation of performance of the database during this period?
A: You might
Q: If downtime/degradation of performance are a possibility whilst we switch service tiers, what do Microsoft recommend we do to safeguard against this? Should we create a second database on a higher tier level and then export the data from the lower tier and
import to the higher, before switching over? How do Microsoft recommend we switch tiers in a production environment with minimal disruption?
A: If you want to upgrade the tiers due to degradation of performance, you will have to create another database on a higher tier and import the data.
One of our key reasons for moving to Azure hosting was the seamless scalability it appeared to offered. As you can imagine, the responses above are a major concern for our production environment. Does anyone else have any thoughts or concerns in this respect?

James,
I reviewed the support incident you referred to and believe that the questions you asked may have been answered later in the interaction you had with the engineer. For the benefit of others viewing this forum I want to reiterate the answers
to your key questions here as well.
Q. What is the behavior when you reach the limits for the service tier?
A. Each service tier currently has limits on 4 different dimensions (CPU, physical reads, log writes and memory) of resource consumption. When you reach one of the limits, the behavior depends on which resource limit you are hitting, but
generally speaking is consistent with the behavior you would see with a similar hardware limit in the SQL Server box product. For example, when you reach the CPU limit your queries will start showing more SOS_SCHEDULER_YIELD waits,
the memory limit will cause a higher percentage of pages to be read from disk instead of the buffer cache (PAGEIOLATCH_xx waits), etc. This set of limits does not directly abort any of your queries--they just run longer as they
vie for the fixed set of resources made available to your database. In a system where the load greatly exceeds the resources, queries may start to time out.
The new service tiers continue with the Web/Business edition behavior of limiting the number of sessions and concurrent requests (worker threads) you can have. When you exceed these limits you'll get error 10928. Note that
each tier in Basic/Standard/Premium have different values for these limits (http://msdn.microsoft.com/en-us/library/azure/dn369873.aspx) than Web/Business and thus may encounter the errors at different usage levels. The key is choosing the appropriate
service level for the application, and to facilitate that the sys.resource_stats view shows historical usage information so you know where you stand as far as reaching any of the limits. This resource consumption data is also available in the portal.
Q. Is it possible to switch service tiers, and is there any disruption when you do so?
A. Yes, you can change between service tiers as described in this MSDN documentation (http://msdn.microsoft.com/en-us/library/azure/dn369872.aspx). This can be done through the portal, powershell, or REST APIs. [The preview currently has a restriction
where legacy servers don't support switching to Basic/Standard which is expected to be removed in the near future.] The link above outlines the limits on the number of tier changes you can do in a 24 hour period, expected time to perform the change, and
the client disconnect that occurs.
If you have further questions, feel free to re-engage on the support incident or reply to this forum thread.

Query regarding connecting dashboards with SQL DATABASE using WSDT

Hello Sir,
I am trying to connect dashboards with Sql database via WSDT, but i have encountered the same problem as described in your SAP community blog (SAP Web Service Design Tool: From web service creation to Xcelsius consumption).
when i tried connecting CR server with WSDT ,it still shows that total number of available licenses is 0.
What can be done to solve this issue.
for your detail reference, we are using CRS NUL version's 60 days Evaluation keys and same with Xcelsius Departmental edition.
I would really appreciate, if you revert back to my mail as soon as possible

Which version of Crystal Reports are you using? The regular ReportDocument SDK probably isn't robust enough to handle this, unless you create a connection using that connection string at design-time which you don't change at runtime. You might be able to add those properties using the in-proc RAS SDK, though. This is available with CRXI R2 as of SP2, and CR2008.

Advise on SQL database process

Dear all,
We have build our own product CMS platform configuration which is running on SQL server and CMS web site link to it.
We will lauch our product soon but need to identify the correct hosting plan for not having any further issue.
For exemple for now all is hosted in our company azure account with a Standard Basic 5 DTU's.
When we go in production we can expect some connection and big amount of data on our database.
My question are as follow :
- Does using a single database storage for my potential Customers would be enough ?
- How should I plan backup efficiently ?
- Should I plan a safety replication process somewhere in azure or duplicate the storage in order to switch in case of lack of place ?
My concern is to avoid my database beeing full while customers increase
Thanks for your advise and help
regards
serge

Hi Solatys,
- If I select by default STANDARD Azure database, which size, DTU, etc should I select ?
For this question, you may reference the below link. You can scale your Azure database performance based on the real-time requirement.
Azure
SQL Database introduces new near real-time performance metrics
- If for instance the initial URL of the web portal connected to SQL server1 has a trouble, how can I switch users transparently to a second replicated server in order that user will notify anything ?
Azure SQL Database has a built-in high availability subsystem that protects your database from failures of individual servers and devices in a datacenter. Azure SQL
Database maintains multiple copies of all data in different physical nodes located across fully independent physical sub-systems to mitigate outages due to failures of individual server components, such as hard drives, network interface adapters, or even entire
servers. At any one time, three database replicas are running—one primary replica and two or more
secondary replicas. Data is written to the primary and one secondary replica using a quorum based commit scheme before the transaction is considered committed.
If the hardware fails on the primary replica, Azure SQL Database detects the failure and fails over to the secondary replica. In case of a physical loss of a replica, a new replica is automatically created.
So there are always at minimum two physical, transactionally consistent copies of your data in the datacenter.
Azure SQL Database Business Continuity
- IF I select the Maximum size of the database, what will happen in case it will be nearly full and need to provide more space ?
Insert and update transactions that exceed the upper limit will be rejected because the database will be in read-only mode. The maximum size has been gained from 50GB to 500GB as of now, you may have no concern about it. You can
set a monitoring alertto
notify the storage utilization and CPU percentage etc.
If you have any question, feel free to let me know.

Which is better for performance Azure SQL Database or SQL Server in Azure VM?

Hi,
We are building an ASP.NET app that will be running on Microsoft Cloud which I think is the new name for Windows Azure. We're expecting this app to have many simultaneous users and want to make sure that we provide excellent performance to end users.
Here are our main concerns/desires:
Performance is paramount. Fast response times are very very important
We want to have as little to do with platform maintenance as possible e.g. managing OS or SQL Server updates, etc.
We are trying to use "out-of-the-box" standard features.
With that said, which option would give us the best possible database performance: a SQL Server instance running in a VM on Azure or SQL Server Database as a fully managed service?
Thanks, Sam

hello,
SQL Database using shared resources on the Microsft data centre. Microsoft balance the resource usage of SQL Database so that no one application continuously dominates any resource.You can try the
Premium Preview
for Windows Azure SQL Database which offers better performance by guaranteeing a fixed amount of dedicated resources for a database.
If you using SQL Server instance running in a VM, you control the operating system and database configuration. And the
performance of the database depends on many factors such as the size of a virtual machine, and the configuration of the data disks.

Accidentally overwritten a sql database - Recover possible?

If it means restoring the database with the 'Practice Template' then hardly there is a way except some previous MDF or LDF files placed somewhere.
Restores operation overwrites everything including schema, data etc. so hard to rollback.
However, if it just a matter of overwriting a few tables (check how the overwriting was done. Was it through the User Interface or the application or through the SSMS or script etc.
I am not sure about Salon Iris app but many application who allows a template to be imported to overwrite the database operates on few master tables to change the status (accessibility) of the records. But it all depends and varies for application based
on their Technical design. As Erland has suggested you may contact the vendor for to understand this more clearly.

I need to host a website with a SQL database - Azure pricing details are too confusing

Hello,
I need to give a potential client a hosting price for a somewhat simple web application they want me to build. I told them it shouldn't be a problem. After gathering the requirements, I figured I would use the following technology to build and host
it:
ASP.NET 4.5
MVC 5
1 SQL Database ~ 25GB with options to expand and also with a backup
SSL certificate needed
Hosting would be on Azure because I have some experience using Visual Studio 2012 and integrating the Visual Studio Online (TFS) source code and scrum web applications. I've never actually spun up a website with a SQL database using Azure before, but I
imagined it wasn't too difficult to find a general hosting plan to support the above requirements.
The use of the website will be very simple and limited to the basic CRUD operations. Will support forms authentication using the Identity 2.0 framework. The web applications main purpose is to fill out a form for new accounts, have a search page for
those accounts, a page to view a created account and add notes to it. So performance wise, it isn't asking for much. I just want it to be fast and secure.
So I start looking on the Azure's pricing landing page which is here: (can't put links in here, but search Azure pricing on Bing) and I see this Pricing Calculator, so I click it
First thing I notice is the Websites tab doesn't mention SQL Database - in fact the Data Management is a separate tab from Websites. And if I made my selections on the Websites tab, the estimated monthly price doesn't stay the same when I go to the Data
Management tab - so I get the illusion I have to have two separate purchases.
I'm not exactly sure if the Pay as You Go billing feature would be okay because it's just a bit scary to leave every monthly payment up to chance; somewhat. Would love to know if there is other payment options that I could see for what I described above.
I want to use Azure to host my asp.net website - it makes sense and the integration with Visual Studio is amazing. I love the publish feature for both MVC 5 Projects and SQL Database Projects.
Thanks in advance for the help!

Hello jdevanderson,
I suggest that you start by looking at the pricing TIERS for the Azure website. This link will give you clarity on different Service TIERS that are availaible:
http://azure.microsoft.com/en-in/pricing/details/websites/
You can guage your requirement and choose the Service TIER accordingly.
And regarding the database, you are right about it. You will be charged seperately for the database. You can refer to this link that will give you clarity on SQL database pricing:
http://azure.microsoft.com/en-in/pricing/details/sql-database/
Refer to this link for more information on 'How pricing works':
http://azure.microsoft.com/en-in/pricing/
Use the full calculator to add your website and the database to get an estimated cost:

Hi sid_siv,
Only the first record is inserted because of the scalar variables of the stored procedure(SP), when you call the SP, only one row is passed. To get all rows inserted, you can either declare a
table-valued parameter
(TVP) for the SP or using an Oracle linked server in the SP.
Create a stored procedure with a table-valued parameter
As you mentioned linked server is not good in your case, then TVP SP can be the only option. Regarding how to call a SP with TVP parameter in BizTalk, that's a typically BizTalk question then. I would suggest you post your question in a dedicated
BizTalk Server forum. It is more appropriate and more experts will assist you.
If you have any question, feel free to let me know.

UUT Result log in SQL database?

Hello All
I am facing a requirement where i want to log results of sequence execution[only the complete seq result and NOT step results] to SQL database BUT as and when the UUT_ID varies the entry should be made into a new column with the same name as UUT_ID. As of now whenever i execute a sequence with different UUT_ID, a new row gets added as a result.
Please reply back with your suggestions asap, as this very urgent for me :-)
Regards
Nitin Goel

But in my opinion, that's just a way to display the results - not a way to store the data. I also have thousands of test cases and tens of thousands of different UUT each month. Each UUT has a separate record (a unique row) and yet if I design a proper query and report format, I can show the results exactly like you have. The design of a relational database should not be the same as a report design, imho.
A database is designed to have unlimited rows (dependent only on storage space). I'm not sure a db can have unlimited columns. That would be something you could check with your dba. Dynamically adding a new column and doing an update to an existing row would probaby be much slower than just doing an insert.

Data Search In SQL Database

Hi, i want user to type a string in textbox, and i will search, if textbox.text exists in my SQL database table or not. Below is the code i'm using :---------------
string txtname = (txtEmpName.Text).Trim();
sQuery = "select * from tbUser where UserName='_username'";
sQuery = sQuery.Replace("_username", txtname);
SqlConnection objConnection = new SqlConnection(source);
objDataAdapter = new SqlDataAdapter(sQuery,objConnection);
// DataTable dtTable = new DataTable();
if (objConnection.State == ConnectionState.Closed)
objConnection.Open();
objDataSet = new DataSet();
objDataAdapter.Fill(objDataSet);
// objDataAdapter.Fill(dtTable);
or i want to search if "txtname" exists in "tbUser" table.
Thanks & Regards.
Manish S. Anand

This is a very poor coding, Unfortunately not fit anywhere :-(
This code is a security risk (sql injection)!
He should use SqlCommand class with parameters!
but yet if i understand the problem he is facing, then the problem is in the SQL part of the code and not the Dot.net :-) therefor it is fit to this forum. Basically the code should work, but as i understand from him his problem is in the
result set come back from the query filter. If so:
* the problem is that he use:
where UserName='_username'
instead of:
where UserName='%_username%'
and he do ask about the search problem :-)

If you need more information please ask i really have to get this sorted out.
Thanks in advance!

Hi Turkstra,
I have tried to use EF to create Azure SQL database, it works as expect, the database 'jambordbcreate' appear in my SQL Azure, below is the detailed codes.
using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace CodeFirst
class Program
static void Main(string[] args)
Database.SetInitializer(
new CreateDatabaseIfNotExists<SchContext>());
using (var db = new SchContext("Server=tcp:****.database.windows.net,1433;Database=jambordbcreate;User ID=vote@***;Password=***;Trusted_Connection=False;Encrypt=True;Connection Timeout=30"))
string name = "jambor";
var student=new Student(){Name=name, ID="1a"};
db.Students.Add(student);
db.SaveChanges();
db.Database.Initialize(true);
public class Student
public string ID { get; set; }
public string Name { get; set; }
public string age { get; set; }
public string sex { get; set; }
public class School
public string ID { get; set; }
public string Name { get; set; }
public virtual List<Student> Students { get; set; }
public class SchContext : DbContext
public SchContext(string connection):base(connection)
public DbSet<Student> Students { get; set; }
public DbSet<School> Schools { get; set; }
I suggest you check your SQL connection, after run your code, please refresh azure portal to see whether your database is exist. Hope this give you some help.
Best Regards,
Jambor

An error has occurred while accessing SQL database or system resources. If this is the first time you have seen this message, please try again later. If this problem persists, please contact your administrator.

I have SP Server 2010, and when I try to DELETE a rule within an existing Audience, "Property (Account Name) = domain/username", I get this error, "An error has occurred while accessing SQL database or system resources. If this
is the first time you have seen this message, please try again later. If this
problem persists, please contact your administrator." When I try to "MODIFY" the rule I get this error, "One or more values typed on this page are not valid. Check the text for the indicated fields."
The last time I checked it was working, I'm not aware of any new updates installed recently? I did a full Profile Synchronization as well, but still not working, please advise? -- Evenstarline

Hi Sara,
First of all thank you very much for your prompt responses. Here are my comments to each of your suggestions below, and just to let you know I am using a Farm Admin account.  I
was able to do this way after we upgraded from SP 2007 to SP 2010 as well.   I would like to mention I'm not a SP expert, just been given the responsibility due to another person handling it just left, so apologize with some of
my novice questions below?
1. When I change the Operators to "Contains" or "Not Contains" get generates this error below.
     Error generating in red towards top of the audience page..."One or more values typed on this page are not valid. Check the text for the indicated fields."
     Error occurred where you enter your "Value"..."Could not resolve the user identity. Please re-enter the account name."
2. We have a 3-server-tier topology (SPWeb, SPDB, and SPFarm). Does the updates only apply to where the Central Admin is installed, which is the "SPFarm"? I checked all
3 servers, and NONE of the updates (KB2899494, KB2889845, and KB2883055) you'd mentioned are installed.
3. I'm new to IISRET, I need to be extra cautious of what I run in production, is this safe to run with no problem? What does it do? And How do I run it?
4. I'm also new to viewing the ULS log. I'd just downloaded a viewer for it. I'm assuming the only logs I need to be concern with viewing are within the SPAdmin (where Central
Admin is installed)? There's so many of them, what should I be looking for exactly?
