Domain Name onlinethailandbooking.com Does Not Exist In The Database
DotNetNuke supports multiple portals from a single database/codebase. It accomplishes this by converting the URL of the client browser Request to a valid PortalID in the Portals database table. The following steps describe the process:
Web Server Processing
When a web server receives a Request from a client browser, it compares the file name extension on the target URL resource to its Application Extension Mappings defined in IIS.
Based on the corresponding match, IIS then sends the Request to the defined Executable Path ( aspnet_asapi.dll in the case of ASP.NET Requests ).
The aspnet_isapi.dll engine processes the Request in an ordered series of events beginning with Application_BeginRequest.
HttpModule.URLRewrite OnBeginRequest ( UrlRewriteModule.vb )
The Request URL is parsed based on the "/" character
A Domain Name is constructed using each of the relevant parsed URL segments.
Examples:
URL: http://www.domain.com/default.aspx = Domain Name: www.domain.com
URL: http://209.75.24.131/default.aspx = Domain Name: 209.75.24.131
URL: http://localhost/DotNetNuke/default.aspx = Domain Name: localhost/DotNetNuke
URL: http://www.domain.com/virtualdirectory/default.aspx = Domain Name: www.domain.com/virtualdirectory
URL: http://www.domain.com/directory/default.aspx = Domain Name: www.domain.com/directory
Using the Domain Name, the application queries the database ( Portals table - PortalAlias field ) to locate a matching record.
Note: If there are multiple URLs which correspond to the same portal then the PortalAlias field must contain each valid Domain Name in a comma seperated list.
Example:
URL: http://localhost/DotNetNuke/default.aspx
URL: http://MACHINENAME/DotNetNuke/default.aspx
URL: http://209.32.134.65/DotNetNuke/default.aspx
PortalAlias: localhost/DotNetNuke,MACHINENAME/DotNetNuke,209.32.134.65/DotNetNuke
Note: If you are installing the application to a remote server you must modify the PortalAlias field value for the default record in the Portals table according to the rules defined above.
I look into the database dbo.portalalises but there is only 2 entries of portal but i have 3 portals..i think it can't generates the portal id automatically?
how this error be solved?

Answer 1

Check your permissions on your web folders match those of the AppPool your site runs under on the new host
Verify your database connection and permissions
Verify that your entry in the PortalAlias table in the database is correct for your new host

Answer 2

For anyone having this issue, I had the same issue, after I made sure that I have updated the "Portal Alias" table in db, to have a HTTP Alias (for my local host, I set it to localhost:8089 which was equal to what I had set up in IIS binding for DNN website), with the portal ID of 0 (as my portal id was 0), I was checking to be sure I have updated web.config file with data base connection strings, but then I realized there were two points for database connection in web.config, and I was missing one of them. So make sure to update both two connections as:
1) <connectionStrings>
2) <appSettings>
Hope this helps.
