We have been using JasperReports (community edition) and its working fine. But we need to implement interactive reports (which are not supported by community edition)
I have been looking for a simple solution for my reports and came across apache superset. I have installed the superset on Windows linux subsystem (we are a windows shop), i have few question and hopefully you guys can answer that:
Is it stable to install superset on windows linux subsystem for production environment?
Can superset works on just plain oracle relation data?
If there are any other open source project i should look into please let me know.
I'm a committer to the Superset project. Unfortunately Superset isn't officially supported on Windows (or even WSL). It may work but the community hasn't created a set of best practices / recommendations here nor is Windows actively tested as part of the development process.
But Superset has been tested against many Linux flavors, so that's probably your best bet.
Also, can you clarify what you mean by "plain oracle relation data"? The Superset community has added the following documentation for working with Oracle SQL databases: https://superset.apache.org/docs/databases/oracle

How can I create a database using SQL in c++?
I tried going according to the steps I found on a website(which required all this to be on codeblocks) by downloading the SQLAPI++ library for c++.
Next it instructed to download oracle c++ call interface, which I downloaded but didn't understand, how to integrate the library with my Codeblocks project.
If you know any other method it would be much appreciated.
In general:
Standard c++ doesn't support SQL database/server connections out of the box. You need to have a 3rd party product to achieve this.
Many SQL standard compliant DB systems support C or C++ APIs you can use for that.
To name a few:
SQLite
PostgreSQL
MariaDB
MySQL
... a by no means complete list ...
Another alternative is to use a generic ODBC interface implementation, which might also support specific database servers, and SQL standard versions.
In particular:
Codeblocks is ypur IDE, it manages projects and their dependencies on libraries.
You seem to have a solution at hand, which uses the sqlapi++ framework library
You need to integrate the underlying SQL server system in turn of configuring that above mentioned API
You may need to link the native support for that specific SQL API of the server system
To do these steps mentioned above you'll need to install (maybe development versions) of the above mentioned APIs, SDKs, ... (whatever they'll call it) and integrate those with your IDE project (related Q&A link regarding this).
I have VS2017 and plan to do some C# development that needs to access Oracle 12c database.
I went in Oracle site and downloaded ODTforVS2017_122011.exe. The installation was successful.
But when I tried to declare my connection type OracleConnection, my project does not know it and I can not reference Oracle.ManagedDataAccess. I had to go to Nuget to install them to satisfy the compiler.
So, my curious question is: is the ODT installation from Oracle site necessary or Nuget installation only would suffice? I just do not want to install to much irrelevant stuff that I would not be able to justify.
I don't believe you need the tools, no. They're Visual Studio features, rather than tools needed at execution time.
From the download page:
Oracle Developer Tools for Visual Studio enables Visual Studio data features such as Server Explorer integration, TableAdapter Configuration Wizard and Entity Designer and also includes many useful Oracle specific tools.
So you may find it useful to have those tools, but I don't believe they're required on every machine where you want to either develop or deploy your application.
I have often faced the issue ‘Service unavailable’ in ColdFusion website and need to restart the service manually. Sometimes, also need to restart the host computer.
I checked Event Viewer but I do not find any error related ColdFusion.
I am not familiar with ColdFusion.
Kindly help me. I would like to check why it happens and to solve this issue.
ColdFusion Version 8
Windows Server 2008 R2 Standard - Windows 7, 64bit
IIS Version 7.5
Thank you.
To find out what is actually crashing your CF server you may find information in the "out" log. Look in the /runtime/logs directory for a file called "coldfusion-out.log" or something similar. This is where standard out goes in a running CF application. There is also a /logs directory in your application that may give additional information.
Finally, you may have a hotspot error - an abend. Look in the /runtime/bin directory for a file similar to hs_err_pidXXX.log" (where XXX is some number). If you do have such an error take a quick look to see if it is an "out of memory" error. That's the most common.
I have a post on where all those log files are located. It is from the CF8/CF9 days so it may be useful to you. Of course everyone will tell you to upgrade as well. :) Good luck!
There are two places to look with problem like this: the application server behind CF (JRun for CF8) is the connector between CF and IIS. Adobe CF uses old (IIS6?) style ISAPI connectors that may need to be rebuilt - later versions of CF have a 'rebuild connectors' batch file in cfusion\bin\connectors (something like IIS_connector.bat) but it has been a while since I've had CF8 to look at. At the very least, be certain that you have the last CF8 update from Adobe as they sometimes want you to rebuild connectors after installing them.
A better solution for newer versions of CF (10+) is to use Bilal's Boncode AJP connector - I don't think it supports CF8 but haven't tried it.
CF 8's End-Of-Life was over four years ago and later versions stopped using JRun in favor of Tomcat, which is a bit easier to troubelshoot. If you have a development environment available, you might try running your codebase on CF10 or CF11; if you have to support this application for the foreseeable future, better to do it on something resembling a current version of CF. You could also have a look at Lucee 4.5 for an OSS alternative.
We are going to be switching to Sitecore for our CMS and my team uses Macs. We have no .net, c# experience but are excited to learn. I understand Microsoft recently released Visual Studio Code to work on Mac, and I've looked into Xamarin. Can someone provide any tips for a Mac guy?
Visual Studio for Mac will not help you because Sitecore quite tightly relates on windows features like IIS and windows filesystem with drives and paths; also the rest of cross-platform ASP.NET 5 features (like owin etc.) are not yet supported by Sitecore.
At the moment the best way to work with Sitecore on Mac is virtualisation and in particular - Parallels Desktop for Mac. I am using that myself for last 3 years - that is the most convenient way. Parallels Desktop is a virtual machine solution that integrates your Windows VM very tightly into Mac, you can run multiple (let's say 2-4) Windows virtual machines at the same time (nice to test Content Management / Content Delivery distributed between separate "machines" just on one Mac) - they are all connected to each other and Mac by a "network". Also you will need to have an instance of SQL server (in that case you may allocate a separate VM or simply reference an external SQL server).
Parallels Desktop has a mode called Coherence, when in fact win and mac environments are sort of merged into each other, so you can for example drag-drop from Finder into Windows Exploreк like you do it natively, and get Windows start button at you Dock and many other great features.
However I prefer to run Parallels in a full screen mode on a second monitor to be 1-to-1 like a regular Windows machine. By setting hosts file on Mac machine I can run CMS and hosted websites right from Safari on Mac.
Also virtual machines are stored as folders on your hard drive, so you can easily backup your current state of OS as easy as just archiving that folder, and later revert to that moments you have "saved" - very helpful to experiment, especially if you are a beginner in Sitecore, so you'd not afraid to break anything accidentally.
Good place to start: official website, as well as quickly investigate all its magic on YouTube reviews.
P.S. of course, you may use any alternative virtualisation software, like VmWare etc.
I use Visual Studio for Mac to build my Sitecore solutions. We use a gulp task based on the one that comes with Habitat to deploy changes to files (binaries, views, config, etc...) into a Windows virtual machine running in Parallels on my Mac.
There have only been two things I am missing from Visual Studio on Windows - debugging and Sitecore Rocks.
If you can live without those two things you can definitely develop your Sitecore solutions from a Mac with Sitecore running in Windows.
Is there a way to meet the following criteria in distributing a Web Service to Windows machines?
1) Automatic installation and configuration of the Web Server.
2) No configuration (or even awareness) of a Web Server required by the customer.
3) No prompts to download and install Java or .NET - especially anything after .NET 2.0; those installs / restarts can take forever!
In short, is there a way to deliver a single install process that installs the Web Server along with a simple web app without requiring lengthy installations of pre-requisites? Something for even the most non-technical of users?
.NET's WCF almost meets the requirements but getting .NET updated up to 3.0 / 3.5 is a lengthy process and can be a turn-off for customers, even if the install holds their hand through the whole thing.
Rubyscript2exe was also very close, but it is extremely touchy and out-dated.
I am open to any technology / programming language - just looking for the slickest distribution process for my customers that meets the above three criteria.
I've been doing quite a bit of research on this as it is extremely important to me that my users have a simple installation experience. Here are a few things that I've found:
UltiDev Cassini: Cassini is that convenient mini-server that runs when you debug your web apps from Visual Studio or Visual Web Developer. UltiDev Cassini builds on that and looks pretty promising. It offers support for all non-beta flavors of .Net and integrates right into Visual Studio. Most interesting to me is the ability to include as part of your installer. The only down side is that pesky .Net pre-requisite. I can handle helping users get installed up to 2.0, but the install process to move to 3.0 and 3.5 is way too heavy for the typical user.
RubyScript2Exe: I like the premise of an executable Rails app. However, I attempted to use this on a Mac and it is simply too outdated and requires too many workarounds for my tastes. It's too bad, because I love Ruby on Rails development.
Server2Go: This is my favorite of the three options. It is easily distributable (just send off a zip file) and has a lot of nice options. For example, you can configure it to leave the included Apache server running even after the browser closes - that is PERFECT for a nicely packaged web service. It can also provide a customizable icon in the task bar for shutting down the service if necessary. I think this best meets my needs for the time being.
Please, if you know of any other options, let me know.
Also, you may be wondering, "Why not just write a desktop app?". The simple answer is that I don't need much of a GUI, if any. I need a simple to install web service that can be consumed by various other applications (web, mobile, and desktop included).
