Oracle EM Express not showing all options - oracle

Why I cant see options like 'create user' in Eterprise Manager. I have Oracle database 19C.
My EM Express is showing just the performance.
Bellow you can see in image that in 11g you can create tables and many other objects, just by using the EM Manager

Oracle deprecated the flash-based features of Enterprise Manager Express in 19c and replaced it with Jet-based technology. The new EM Express only shows performance metrics and contains no administrator functions for users, tablespaces, etc.
To revert back to the legacy flash-based EM Express you can use the steps given here: https://logic.edchen.org/how-to-revert-em-express-19c-to-flash-based-back-and-forth/, assuming you can still find a browser that will run Flash at all. Pretty much all browsers dropped their support for Adobe Flash technology almost two years ago, and Adobe has posted the following on their web site:
Since Adobe no longer supports Flash Player after December 31, 2020
and blocked Flash content from running in Flash Player beginning
January 12, 2021, Adobe strongly recommends all users immediately
uninstall Flash Player to help protect their systems.

Oracle 11g R2 Security patch installation

I have Oracle 11g R2 Free version in my laptop for development purpose, But i need to update the security patches given by Oracle. But while doing it it was taking me to a registration page where they are asking for Support Identifier.
Please help me out with this issue.
I'm not much into licencing, but - as far as I can tell - you get access to My Oracle Support (so that you could download patches, read additional documents, etc.) once you purchase (read: pay (a lot of) money) to Oracle because you started using their software in production.
For free versions, I'd say that you get quite a lot - regarding how much you paid for it (i.e. nothing at all), but shouldn't expect to get additional features as well.
If it is, as you said, for development purposes, why would you care about security patches? You don't trust yourself? :)
Therefore, in my opinion, you're out of luck.

Moving a VB6 Application from SQL Server 2000 to SQL Server 2014

Interested to know if anyone has had any experience with moving a VB6 application from SQL Server 2000 to a newer version of SQL Server.
There are VB6 legacy apps on a Windows 2000 Server
These VB6 apps connect to a SQL 2000 Database
We are looking to upgrade from SQL 2000 to SQL 2014
We are reporting with Crystal Reports
The VB6 apps have inline SQL within them
I'd like to understand what the possible implications could be?
Thanks
For one thing, there is no direct migration path from 2000 to 2014. This article (http://sqlmag.com/sql-server-2014/sql-select-steps-migrate-sql-server-2000-sql-server-2014) outlines some potential steps to take to perform the upgrade.
Things that may trip you up not mentioned in this article:
DTS no longer exists so if you have any DTS packages, it will be a project to upgrade/convert them all over to SQL Server Integration Serices (SSIS) packages.
If your VB6 app contains hard coded SQL statements, rather than just calling stored procedures, you could have minor syntax issues that would have to be rectified (so test EVERYTHING)
If you are also looking to migrate VB6 to .NET, there is an upgrade wizard out there somewhere, but it is HORRIBLE, so depending on the need, it may be faster to just re-write from scratch. If you are implying that the VB6 application would just connect to the migrated 2014 database, the note on the main question is accurate, but again...test EVERYTHING.
3a. If you are referencing any old COM components or old OCX controls, it will be a source of pain.
3b. Does your app do any reporting? old 2000 SSRS, or Crystal reports? again, another project.
Good luck!
I've done it, and there were stored procedures / user functions that needed to be updated for compatibility. Here is a Microsoft tool, SQL Server Upgrade Advisor. If you are using inline SQL in your code I'm not sure if this tool will help you. I was fortunate in that most on teh application SQL was implemented as stored procedures inside the database itself.
Here is an MSDN blog post about upgrade considerations and using the Upgrade Advisor tool.

How much data can be stored to the IE11 in-browser database within the windows 8 tablet

Backgroud:
I am building my offline application which stores data into the IE11 in-browser db (Indexdb) using a pouchdb adapter.
My questions:
How much data can I store into the inbrowser-db within the IE 11. My application is intended to work in a windows 8 tablet environment.
There are two versions of IE available from my tabet (usual IE11 and the IE Metro). In terms of the amount of data that can be stored into the inbrowser db is there any difference between the two versions of IE.
From the PouchDB FAQs:
Internet Exporer 10+ has a hard 250MB limit, and will prompt the user with a non-modal dialog at 10MB.
There is also this real-world research that was done by Raymond Camden. You might also find "Working with Quota on Mobile Browsers" to be useful.
I don't know if there's any difference between IE11 and IE Metro. If you do the research, please update the PouchDB FAQs and let us know. :)

Oracle Forms 10g ActiveX controls

I can't find much documentation on this and I haven't worked with Forms before. As I understand it, Forms 10 doesn't support ActiveX controls any longer.
Does that mean the controls won't work at all in WebForms or that Oracle just doesn't handle bugs on this issue any longer? Has anyone tried using ActiveX controls in Forms 10 and succeded? Can the controls be somehow wrapped in Java and work?
If it helps, I'm seeking to build an ActiveX control to communicate with hardware devices such as scanner and a photo camera, take pictures, process the images and then return them to a WebForms running server.
You are right using Active X and Oracle Forms when deployed on the web is not supported by Oracle.
Oracle recommend the use of Pluggable Java Components instead. The following paragraph is taken from here
I currently have a client-server application that uses an embedded
ActiveX control to communicate with an external device. How can I
maintain this functionality when I deploy the application on the Web?
Assuming that the device in question (for example, a Scanner) is
attached to each client machine, rather than the server, you will use
a Pluggable Java Component (PJC) to extend the capabilities of the
Forms Java Client and allow it to talk to the hardware in question.
JDeveloper 3.2 provides a Wizard to help you build such pluggable Java
Components.
Whether your Active X control will work or not, unfortunately the answer is that it might or it might not. If not you are on your own.
I agree that documentation is hard to find. The best place to start is the Forms Page on OTN Followed by the Forms 10g technical listings and the even older 9i and earlier docs.

Simple database application for Windows

I need to build a simple, single user database application for Windows. Main requirements are independence from windows version and installed software. What technologies (language/framework) would you recommend? My preference for language is the Visual Basic.
EDIT: What about VB.Net and SQL Server Compact Edition?
I would recommend Sqlite. It's completely self-contained, and public domain so there are no license issues at all.
Single user or multi user?
For single user, the answer would be SQLite
For multi user (or multithread), try MySQL or PostgreSQL.
Since your requirement is a windows based application i would suggest that you go with sql server 2005 express edition which is a free tool, but with certain small limitations. you can upgrade to a bigger version when you go with a paid version.
There are other DB engines like SQL Lite or FireBird, choose them if the support and growth options they provide are good enough for you
Additionally, Visual Basic is eof lifed. VB.NET might be a better windows based platform currently. It would give a better platform / features to start with and when you want to expand the talent you have working on the project, i assume .NET talent might be more available than programmers who want to work with a dead language.
duplicate of What options are there for a quick embedded DB in .NET?
I'll repeat my answer from there:
"Or theres Esent, the built in database that exists in every copy of windows. Read about it here: http://ayende.com/Blog/archive/2008/12/23/hidden-windows-gems-extensible-storage-engine.aspx" and http://www.codeplex.com/ManagedEsent
SQLite will work for a local desktop application. If you want several users, a few gigas of data, and multiple connections I would use mysql or Firebird.
http://www.mysql.com/
http://www.firebirdsql.org/
FireBird SQL server will be thing of choice. It can be used in both embedded and multiuser mode like traditional databases. It implements many of the SQL standards and has strong community base. It is available for Windows, Linux, Solaris, OS X, HP-UX
As mentioned, SQLite is a great single-user database. This page has VB/SQLite examples. Once concerns is that SQLite parses foreign key constraints, but does not enforce them. You can use this code to generate "foreign key triggers" for SQLite, thus gaining an easy to use database with FK constraints.
Depending on how demanding your database needs are, though, you might want to consider MS Access.
I used SQL Server Compact Edition. It's like sqllite. A single SDF file accessed using ADO.NET.
You can develop your application using Visual Basic .NET and manage you database (add tables, columns, constraints, etc...) using Visual Studio.
SQLite may be what you are looking for. http://www.sqlite.org/
Depending on your needs for the application.
You could use SQLLite which is a very nice database with no installation required.
You could also use Microsoft SQL Server: SQL Server Compact 3.5.
Both are free!
It's not quite clear from your post whether you want a web application or not.
For a web application, MySQL works effectively on the Windows platform. You also have nearly limitless options for development environment including, PHP, Ruby on Rails, Django, and .Net.
If you are looking at a desktop application, MS Access might be suitable ... incredible easy for simple applications.
Well, assuming you don't have any prior experience...
You need some kind of persistence storage (for example a database) and a client.
For the storage you could use almost anything. For example you could create your DB in MS Access and just ship it as a file, using ADO to access it.
Other options are MS SQL Express edition (comes pre-installed on some machines or could be installed for free) and plenty of open source databases like SQLite
For the client side you could not go wrong with VBScript and ADO (using OLE DB drivers). They come with every Windows installation since Dark Ages, you will have plenty of references/tutorials/answers online.
A drawback: no UI to speak of, so you'll have to build a command line interface (which was for a 'simple' application).
If you want to build a UI I would suggest using .NET WinForms. The overhead will be substantially bigger but .NET is now installed on all XP/Vista machines and even if it is not you could always install the framework with you application.
If you want to build application that can move to other pc easily,I prefer Microsoft Access it is small database easy to use and no need to install.It suites for application like Addressbook,mini crud system.
But if you want to develop enterprise database system you should use MySQL instead.
I do not understand what you mean with "independence form [...] installed software". You ever need at least the DBMS installed as well as one client or user interface.
I recommend using MS Access. It is easy and cheap for simple, single user tasks and rapid prototyping development. Only development version have to be bought ("normal" Access) to create DBs. Runtime version of Access 2007 can be downloaded free of cost from Microsoft Homepage - for using only the database you created.
Also it combines DBMS and GUI frontend in same tool.
Dare I mention MS Access...?
If you are looking for small footprint (up to a few MB) and easy deployment (end-user should only install your application to get it working), then your options are SQLite and Firebird embedded.
Of those two, I'd pick Firebird any time, because of it's full support for SQL (you can't, for example, drop a column in SQLite), ACID compliance, and ability to go client/server without any changes (just change the connection string from embedded to server) to the code if you ever decide to let multiple users work on the same database.
Not to mention that you can use full server to develop (which means your application and database administration tool can be connected to database at the same time).
I'm successfully using Turbo Delphi (free for commercial and no commercial use) + ZeosLib (zeos.firmos.at).
The only things you need to distribute with your .exe are the database client dlls (no need to install the client, just put the dlls in the same directory).
Would Kexi work?
I can recommend from personal experience "My Visual database"
free, no code, no sql, just drag and drop.
http://myvisualdatabase.com/
Best Option would be to create a Win32 native application using Delphi and use SQLLite as the database.
Reason being Delphi can produce native win32 applications without any other product being installed on the machine.
