I see in documentation that Flyway works with Java and jdbc. However, our project uses SQLServer with ODBC and C++. Thus, is it possible to use Flyway in such a case?
Thank you.
Yes. You should be able to use it no problem with the command-line tool: http://flywaydb.org/documentation/commandline/

I'm trying to use MongoDB connector https://store.wso2.com/store/assets/esbconnector/details/3ce6cbda-c62b-41e0-9706-f75da51e50ee and found some missing options, is it possible to customize it? where is the source code of the connector?
Yes, you can, you can fork the code and do the changes you require, and use it. The source code is located here. You can also consider contributing it back to WSO2.
If you want to build your own connector from scratch you can take a look at this.
I would like to write a JUnit Test using any kind of embedded Elasticsearch engine in order to test my services which should create indexes with mappings on start-up. What is the best way to do it?
Probably, it would be also enough to use ESTestCase. Unfortunately, I cannot find simple usage examples. Could anyone provide one?
There is no embedded Elasticsearch since 5.x any more. I would use Testcontainers for this: https://github.com/dadoonet/testcontainers-java-module-elasticsearch
PS: This code will soon move to the Testcontainers repo.
I want to do simple stuff like adding entries and reading entries by index. What libraries are there and which ones are the best?
SQLite would be a good simple SQL database engine, with a simple embedded C++ interface.
SQLAPI++ would be a good choice for many commercial SQL databases (Oracle, SQL Server, DB2, Sybase, Informix, InterBase, SQLBase, MySQL, PostgreSQL, SQLite and ODBC)
One option is to use Microsoft's SQL Server Compact Edition. It is free, and has Visual Studio integration.
You can download it and find out more at the following link:
SQL Server Compact Edition
If you not worried about HUGE concurrency then use SQLite (www.sqlite.org). Download the aggregated version and you only have 2 files: sqlite3.h and sqlite3.c. It's REALLY easy to use and requires no server set up or configuration.
I am struggling to connect to oracle db using GNU C++.Is there any library which I have to install to connect to oracle db using simple c++ (oops).
Please provide me some sample code as well, this is new for me. Appreciate your help.
I asked a similar question before but forgot to mention that I am not using vc++ and proc.
You would need the oracle C++ libraries (OCCI) from oracle. You can find them here:
http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html
Google "Oracle OCCI tutorial" and you should find pretty much everything you need.
Check out SOCI. It supports several database backends, including Oracle, MySQL, Postgre, ODBC, etc. Using this library would make it easier for you to migrate your application to a different DB, if necessary.
There's a code sample here. And several more peppered in the documentation.
i have a question about the theory here, i'm just starting a project which is based on C++ applications integrating with oracle DB's, i've came to two choices, OCCI, and OCI
the OCCI is said to be aimed at C++ environment, but i was wondering, if it would be any good to use the OCI libraries from my C++ app since it is said to have better performance, or would i run into compatibility issues ?
thanks in advance :)
You can have a look at OTL it's a wrapper above the OCI or OCCI (not sure) will give some templates and samples to start with oracle connection in c++.
In my case, my company have about a thousand stores.
To connect Oracle / Oracle thru an MS C++ multi-thread service we perform the following tests on each thread:
Validate DNS (gethostbyname)
Try to open SCManager of the store (OpenSCManager)
Verify if Oracle Service exists on the store (OpenService)
Verify if Oracle Service is running (QueryServiceStatus)
After all, we try to connect (ado->Open)
This procedures minimize possible errors like 0xE06D7363 when connecting to a external server.
