I recently installed Oracle APEX and now trying to access APEX through
http://localhost:8080/.
When I access the page, I encounter this error. I am using Oracle Database 11g R2 and Apex Ver 18.1, I installed Oracle Data Services. When i did following step It shows me rendering error. I run following script to resolve image problem
reset_image_prefix.sql
Enter the Application Express image prefix [/i/] :/i/
my ord_params.properties file have following entry
**standalone.static.images=D\:\\ords.18.1.1.95.1251\\images**
Well, I know that running #apxldimg script helps in such a situation. Did you try it? As a parameter, it expects directory that contains the \apex directory. In the following example, full path to \apex directory is C:\5_apex_instalacija\apex4\apex.
It is a copy/paste from my Apex 4.x installation notes (didn't run it right now):
SQL> #apxldimg C:\5_apex_instalacija\apex4
PL/SQL procedure successfully completed.
old 1: create directory APEX_IMAGES as '&1/apex/images'
new 1: create directory APEX_IMAGES as 'C:\5_apex_instalacija\apex4/apex/images'
I'm totally new to ASP.NET Core 2.0; I created a new Project with In-App Authentication.
When I run the application and try the Register function, I get an error message saying that
the table "AspNetUsers" does not exist.
That is OK and expected, I did not run the Migration scripts. For less confusion, I then deleted the Migration folder.
The problem I want to solve is I want the Register functions to register the user to my custom database. I already updated the settings in appsettings.json for this.
I made a Notepad++ search in the entire folder for AspNetUsers and found 0 hits. Yet, when I run the application again, the error message is the same, that the table "AspNetUsers" does not exist.
I am very confused. How does it know to look for that table if that text does not exist in the entire project directory?
How do I make it use my own database? I looked around, but I was unable to find any solutions. This is my last resort.
Thanks!
AspNetUser is table name for ApplicationUser object in database and there is no automatic migration in EF Core yet, so you have to generate migration files by your self. in database run following command nuget console:
Add-Migration Initial
after running this command a Migrations folder would be added. then run next command to apply migration to your database:
update-database
I have managed to setup and run EF5 with ODP.NET and it works like charm. However, I am facing an issue with accessing Oracle stored procedures created inside the package. I am not able to see the procedure from the Entity Framework 5, in the .EDMX file. The procedure which are not inside the package can be added and accessed.
Is there some setting required to make this possible?
I am getting following error upon clicking Package in the Server Explorer: ORA-00904: "SELTAB"."OBJECT_TYPE": Invalid identifier
See this image http://postimg.org/image/qfs93q9ap/
Edit: Oracle Developer Tools for Visual Studio 12.1 requires Oracle Database 10.2.0.3 or later. The error you are seeing is caused because the OBJECT_TYPE identifier is not introduced until version 10.2.0.3 of the database.
I created my data model using Entity Framework, when I try to generate the database from the model, it generates the script but when I execute it I have the following error:
Msg 911, Level 16, State 1, Line 1
Database 'MyOp' does not exist. Make sure that the name is entered correctly.
I don't know where is the error, I don't think that is a problem of permissions.
Thank you for your help
Ok I found it, sorry to ask such a question.
The problem was that my database was not created in my server, so I created it that way:
In SQL connecxion in visual studio, right click and add new database,
in the dialog box of the server name type ".\SQLEXPRESS" (without quotes).
Type the name of your db in the database name.
Now when executing your script, choose your database name instead of "master" in the dropdown list next the the excexution button.
WARNING: when changing laptop I did'nt find my created database, so you have to copy/paste it in the appdata folder in your application, to copy your database, you will find it in this path: C:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\DATA
you must click disconnect button and then connect button .vs2012 select sqlExpress by defult when you want connect again to your server you must select server name correctly.
I am using Crystal Report 10.2 version. I have applied paging, and when I open the 3rd page, the following error is raised:
Error in File C:\WINDOWS\TEMP\StatReportNewV {94692B41-40A2-4F6A-9551-110BA7D78A37}.rpt: The request could not be submitted for background processing.
Please help how to resolve this.
It's a fairly generic error in Crystal Reports, but you can try the following:
Make sure you're on the latest service pack
Crystal Reports can create temporary files; make sure there aren't an excessive amount of files in this folder.
Run the same query in your database and see if you have any NULL records coming back, which may be causing an exception in your report.
If the report always crashes on the 3rd page, I suspect there is some data on that third page that you're not handling properly, either because of a function, formatting, invalid data type, something along those lines.
