Web Security Membership & Database Permissions - sql-server

I am trying to deploy my site to 123reg but having difficulty with database permissions. I see other people have similar issues, but they all seem to be using entity framework with DBContexts, whereas I am not (I don't think).
I am using the Web.Security.Membership.CreateUser method. All of the database tables are set up. My connectionstring is almost certainly correct as I have the same setup on a different hosting provider which works perfectly. The site can read from the database but fails when it tries to write.
When the method is invoked, I get the following error.
CREATE DATABASE permission denied in database 'master'.
Is there anyway to stop the DefaultMembershipProvider from trying to create the database or tell it exactly where it is?
<add name="Simple.Data.Properties.Settings.DefaultConnectionString" connectionString="Server=ATLAS-SQL-07;Database=mydatabasename;User ID=myuserid;Password=xxxxxx;" />
I'm using Simple.Data (as can be seen the from name of the connectionstring). Maybe this is causing it problems. I don't see why it works flawlessly on my Netcetera hosting though?
To test it out further, I published the MVC4 sample web application to 123reg and pointed to the same database, it had exactly the same issue.

I had a similar problem with 123-reg; and a number of other issues. I found the best approach
was to blank out the call to create database and import a working database, (with one user in it). Make sure you do the import file as ANSI, otherwise you get a random character inserted on the import.
private class SimpleMembershipInitializer
{
public SimpleMembershipInitializer()
{
Database.SetInitializer(null);
try
{
/*
using (var context = new UsersContext())
{
if (!context.Database.Exists())
{
// Create the SimpleMembership database without Entity Framework migration schema
((IObjectContextAdapter)context).ObjectContext.CreateDatabase();
}
}*/
WebSecurity.InitializeDatabaseConnection("TobaContext", "UserProfile", "UserId", "UserName", autoCreateTables: true);
}
catch (Exception ex)
{
throw new InvalidOperationException("The ASP.NET Simple Membership database could not be initialized. For more information, please see http://go.microsoft.com/fwlink/?LinkId=256588", ex);
}
}
}
I have had a number of problems with 123-reg - some of it my fault - some of it theirs I think.
As a heads up on membership - at the moment I am getting problems with the RequireHTTPS attribute. It appears to cause a
'too many server redirects' issue. Yet I thought that attribute was suppose to work out of the box.
Good luck, hope been of some help,
Dave

Mirth- Database writer error

I am trying to create a channel to write to a database from HTTP source.
I have made two destinations both to same database. One destination writes via JavaScript and the other with SQL.
The data gets written to database in the first destination(the JavaScript one) but not through the second(SQL). I am not able to get the tables through "Insert" button also. It gives the following error:
Someone please give me the solution to set up database connection without any flaw. Please note that the database is secured one in AWS instance.
To connect to database via javascript, you will need to select "Yes" under the option to use javascript. Then your connector will look something like this:
var dbConn;
try {
dbConn = DatabaseConnectionFactory.createDatabaseConnection('net.sourceforge.jtds.jdbc.Driver','ServerURL','Username','Password');
// You may access this result below with $('column_name')
return result;
} finally {
if (dbConn) {
dbConn.close();
}
}
Note that you can click on the "generate" button and this template will be created for you in the javascript window.
Based on the information you have given, I am not sure that your method/syntax is the cause to your error. Can you verify that your database driver jar file is located in your installation? (Mine is located at "...\Mirth Connect\server-lib\database"

not getting any error when serilog is not able to insert data in sql server

I am using serilog as logging framework in .net core 2.0 project and i am trying to store the logs in sql server but serilog is not storing any data in database and it is not even returning error.
can any one help how to resolve this issue and is it possible to add file approach to store logs when database fails to store
Serilog.Debugging.SelfLog
You can use the SelfLog property to tell serilog where to log it's own errors (all of us have had to debug the logger at some point).
Sample Code
Because I hate providing an answer without sample code that others might find useful ... here is the code we use to "initialize" our logger (including serilog and seq -- a great combo for generating centralized logs that the devops team can monitor).
Serilog.Debugging.SelfLog.Enable(Console.Error);
ILoggerFactory factory = new LoggerFactory();
factory.AddConsole();
factory.AddDebug();
var env = "PROD"; //MyEnvironment: PROD, STAGE, DEV, ETC
var seqLogger = new LoggerConfiguration()
.MinimumLevel.Information()
.Enrich.FromLogContext()
.Enrich.WithProperty("Environment", env)
.WriteTo.Seq(
"logserveraddress",
Serilog.Events.LogEventLevel.Verbose,
1000,
null,
"LogServerApiKey")
);
if (env.ToLower() == "prod") { seqLogger.MinimumLevel.Warning(); }
factory.AddSerilog(seqLogger.CreateLogger());
}
return factory.CreateLogger("NameThisLogInstaceSomethingUseful");

Play Siena failing to connect to MySQL on GAE

I am using play framework 1.2.7, gae module 1.6.0 and siena module 2.0.7 (also tested 2.0.6). This is a simple project that should run in play deployed on App Engine and connect to a MySQL database in Google Cloud SQL. My project runs fine locally but fails to connect to the database in production. Looking at the logs it looks like it is using the postgresql driver instead of the mysql one.
Application.conf
# db=mem
db.url=jdbc:google:mysql://PROJECT_ID:sienatest/sienatest
db.driver=com.mysql.jdbc.GoogleDriver
db.user=root
db.pass=root
This is the crash stack trace
play.Logger niceThrowable: Cannot connected to the database : null

What is going on here? I am specifying the correct driver and url schema and it's using postgresql driver. Google Cloud SQL API access is enabled, the app is allowed to connect to the mysql instance, I am not using db=mem, ... I am stuck and can't figure out how to move forward! :-((
UPDATE: I thought I found the solution, but that was not the case. If I keep the %prod. prefix and create a war normally (or just don't define any DB properties), then the application will use Google DataStore instead of the Cloud SQL. If I create the war file adding --%prod at the end (or just delete the %prod. prefix in the application.conf), then it will keep failing to connect to the database showing the same initial error.
Any ideas please?
After being stuck for so long on this I just found the solution in no time after posting the question. Quite stupid actually.
The production environment properties in the application.conf file must be preceded by %prod. so the database config should read
%prod.db.url=jdbc:google:mysql://PROJECT_ID:sienatest/sienatest
%prod.db.driver=com.mysql.jdbc.GoogleDriver
%prod.db.user=root
%prod.db.pass=root
And everything runs fine.
EDIT: This is NOT the solution. The problem went away, but the app is using the DataStore instead of the Cloud SQL
At the end I ended doing a slight modification in play siena module source code and recompiling it.
In case anyone is interested, you will need to remove/comment/catch exception in this code around line 97 in GoogleSqlDBPlugin class:
// Try the connection
Connection fake = null;
try {
if (p.getProperty("db.user") == null) {
fake = DriverManager.getConnection(p.getProperty("db.url"));
} else {
fake = DriverManager.getConnection(p.getProperty("db.url"), p.getProperty("db.user"), p.getProperty("db.pass"));
}
} finally {
if (fake != null) {
fake.close();
}
}
For some reason the connection fails when initiated with DriverManager.getConnection() but it works when initiated with basicDatasource.getConnection(); which apparently is the way used by the module in the rest of the code. So if you delete the above block, and recompile the module everything will work as expected. If you are compiling with JDK 7, you will also need to implement public Logger getParentLogger() throws SQLFeatureNotSupportedException in the ProxyDriver inner class at the end of GoogleSqlDBPlugin file.
Strangely, I digged into the DriverManager.getConnection() and it looked like some postgresql driver is registered somehow, because otherwise I can't see why DriverManager.getConnection() would call to org.postgresql.Driver.connect().

How to pass credentials to reportviewer in WPF application SSRS 2008

I am using ReportViewer to show the reports on my windows WPF application using .Net 4.0. These reports are deployed on a separate SSRS 2008 report server and not the local machine. Right now, I am passing the credentials of the server in the following manner:
string userName = configClient.Settings.Get("UserName").Value.ValueXml.InnerText;
string password = configClient.Settings.Get("Password").Value.ValueXml.InnerText;
string domain = configClient.Settings.Get("Domain").Value.ValueXml.InnerText;
IReportServerCredentials irsc = new ReportViewerCredentials(userName, password, domain);
_reportViewer.ServerReport.ReportServerCredentials.NetworkCredentials = irsc.NetworkCredentials;
Also, I am using the following settings with the ReportViewer if it is of any use:
_reportViewer.ProcessingMode = ProcessingMode.Remote;
_reportViewer.ShowParameterPrompts = false;
_reportViewer.ServerReport.ReportServerUrl = new Uri(Properties.Settings.Default.ReportServer);
_reportViewer.ServerReport.ReportPath = Properties.Settings.Default.Reports;
I am using the config file to save and retrieve the credentials for the server access, but I do not think this is a secure way of doing it. I would like to implement this in a secure way where I do not need to take the credentials from the user or from the config file. Both the local machine and the server would be on the same network.
I am not sure how to do it, can this be done through impersonation, I am just guessing as I do not have much idea about security and impersonation. Also, if it can be done, can I get a sample or may be a link to an article through which I can get this done.
The core idea is to avoid storing the username and password on the client. I searched for solution but what I got was very vague in nature.
Please do not close this thread as it is an open question, but it is important for me, as I am approaching deadline and working on too many things at a time. Sorry for inconvenience caused if any.
I have found a way to not pass the credentials at all and still be able to retrieve the reports from the Reports Server, but not without help.
I have configured a new Role assignment in the Report Manager using the URL http://localhost/Reports/Pages/Folder.aspx. Go to Properties tab, and add a New Role Assignment and add Everyone and provide the required right to it.
This way, I would not need to pass any credentials from the client for the ReportViewer. Also, it can be used to configure the access for a selected users.

HTML5 database storage (SQL lite) - few questions

Hy there,
I can't find enough beginner resources on the web about HTML5 database storage usage examples (CRUD)
I'm opening(creating) my DB like this:
var db;
$(document).ready(function()
{
try
{
if (!window.openDatabase) {
alert('Not Supported -> Please try with a WebKit Browser');
} else {
var shortName = 'mydatab';
var version = '1.0';
var displayName = 'User Settings Database';
var maxSize = 3072*1024; // = 3MB in bytes 65536
db = openDatabase(shortName, version, displayName, maxSize);
}
}
catch(e)
{
if (e == 2) {
alert("Invalid database version.");
} else {
alert("Unknown error "+e+".");
}return;
}
});
QUESTION 1: How many databases can i create and use on one domain?
QUESTION 2. How to delete (drop) a database. -> i have not figured this out yet.
To create sql queries you use transaction:
function nullDataHandler(transaction, results) { }
function createTables(db)
{
db.transaction(function (transaction)
{
//first query causes the transaction to (intentionally) fail if the table exists.
transaction.executeSql('CREATE TABLE people(id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, name TEXT NOT NULL DEFAULT "John Doe", shirt TEXT NOT NULL DEFAULT "Purple");', [], nullDataHandler, errorHandler);
});
}
QUESTION 3: How so is the above transaciton failed if a table exists? Is the nullDataHandler involved to do this? Where on the web is there documentation explaining the executeSql API? Arguments?
thx
The spec you're looking for is Web SQL Database. A quick reading suggests:
There is no limit, although once your databases increase beyond a certain size (5MB seems to be the default), the browser will prompt the user to allow for more space.
There is no way, in the current spec, to delete databases.
The executeSql() function takes an optional error callback argument.
HTML5 Doctor also has a good introduction.
Going forward, though, I'd recommend looking at Indexed DB. Web SQL has essentially been abandoned since there is no standard for SQL / SQLite. Even Microsoft has endorsed Indexed DB. See Consensus emerges for key Web app standard.
CREATE TABLE IF NOT EXISTS table_name
will create a table table_name only if if does not exist.
I found the following WebSQL tutorials helpful for basic CRUD operations, as they contained examples, and explained what the code was doing:
A Simple TODO list using HTML5 WebDatabases
HTML5 Web SQL Database
And the following links for SequelSphere (an HTML5 JavaScript SQL Relational Database Alternative to WebSQL that works in all browsers, storing data in LocalStorage and IndexedDB):
SequelSphere basic Usage instructions
API Documentation
Full Index of Guides and Helper Documentation
Using PersistenceJS there is a persistence.reset API which will wipe the database clean.
PersistenceJS Site
For developing / testing purposes, you can view content and delete webSQL, IndexedDB, cookies, etc by searching for your domain name at this URL in Chrome:
chrome://settings/cookies
There, you can delete all the storage for a domain or just certain local storage entities. Yes, the URL implies just 'cookies', but the interface at this URL includes all types of offline storage.
It would be great I think if the Chrome developer tools interface had the ability to right-click and delete a data storage entity in the Resources tab along with inspecting the content. But for now, all I know of is the settings/cookies URL.
It is supported on iOS safari,chrome and some latest version of opera....it's not yet adopted by IE and Firefox that's it......what more one can ask than local db on browser which has relational db system...so u can query it easily and handle complex data....which is very tougher in key vale based systems..
I remember reading it even supports upto one gb.i am not sure....
Note:
1)I'd like to mention one point there is a IDE called Dashcode which let's u build web apps that looks like iOS native.even there also web SQL is used.
2)actually web SQL is a implementation of SQLite on browsers.
3)SQLite is most prefered in both iOS and android as db for native code..
The drawbacks of SQLite:
The Lack of concurrency support but which is not a problem in browser as it's gonna be used by single user at a time..this is a case also in mobile.
Conclusions:
Web Sql is abandoned by w3 that's a sad thing so we've to explore other options.
