I am new to the 'cloud' concept I have a Java based application for data entry which runs well on my LAN.
On my LAN I install:
MySql
Configure Instance ( user name - root, pass - ******)
Dump dummy database entry_db that is in raw format
Then I have a jar executable file which when runs, displays a login screen.
I manage to successfully log in using predefined ID and PASSWORD (user - config pass - ******)
After logging in I configure(d):
Database Type
Database IP
User Name (Root)
Password ****
Database Name ( It auto selects database named entry_db)
In another window I configure(d) Network File Sharing Location:
file shared location
image path
back up data path
config file location in xml
(Note - When I select file shared location, all other files take the same path automatically)
Then I create Admin account rather than Supervisor account or operator account and login with the Admin account and I can now upload data and distribute to all operators.
Here is my problem:
I configure a cloud computer on Hp Cloud (they provide me a static ip) and then import database from xeround.com.
I now have a dns and port number and also a log in form using MY PHP CLIENT
How can I package all this to the same executable jar file to be used from anywhere?
How can I use it just like on my LAN from the web?
What is the optimal configuration for this?
I work in Xeround.
I have read your question and I wanted to point out a couple of things; you should use the DNS in the connection string where you used to put hostname/IP of the MYSQL server machine and the port number where you used to put the MySQL default port (3306).
Other than that you can connect from anywhere there is access to the instance. I suggest that if your jar runs in the HP cloud you create your Xeround database instance there as well (this will yield improved performance).
If you still need help, we will be more than happy to help you. Just send us a quick email to support#xeround.com and we'll take it from there.
Cheers,

We are using Mosaic to load and read data from multiple sources like MySQL, SQL Server, Oracle in around 100 jobs using the reader node of Mosaic.
To configure this reader node to connect these databases, how to create a connection for each one of them? Are these connections globally available in Mosaic?
Mosaic Decisions supports a wide range of connectors.
You can create connections with different data assets by providing required connection details in the Publish tab under Manager Persona.
Publish allows you to create a connection with any available source system by providing necessary detail like IP, Port, username, password, and other such required details to register/publish the metadata from the source system.
Here connections are of two types:
Public: This connection will be available to all. No lock symbol specifies that it is a public connection.
Private: This will not be available to all users. To use this connection you must provide your username and password. If the details are correct, only then the connection can be used. A lock symbol specifies that it is a private connection.
Once the connection is created, its datasets can be published and the same can be used for further processing in Flows.
EDIT
When you click on the Publish tab in Manager persona, you will see a list of available connectors. Refer screenshot below:
For a database course that I'm in, the professor has tasked us with setting up several VM MySQL servers and remote connections. I've found proper documentation to solve most of my problems, but I've pored over docs trying to find a solution to my latest issue.
I've set up an Ubuntu VM on the Google Cloud Compute Engine. I installed a MySQL server to this VM instance, and I need to log in remotely from my laptop. I've followed this documentation https://cloud.google.com/solutions/mysql-remote-access and this youtube video https://www.youtube.com/watch?v=f5qQDm3ciDg.
However, I still get an Unable to Connect to Server message when I test my connection. What could I be overlooking that will help me connect?
Thanks!
So, I slammed my head against a wall for long enough to realize that ssh will be an easier solution than a direct connection.
So, at least for my Windows machine, these are the steps I followed to make the connection:
Download the sql server (You don't need to add a user unless necessary, and you don't change the bind-address in the config file).
Use PuTTYgen to create a private public key pair. Export the private key as an openssh format (in the export options)
Click the edit button on your VM instance then scroll down to the SSH key section.
Paste the public key into the text box (be sure to change the last comment portion to a username on the Linus VM)
Use the SSH connection on MySQL Workbench. Use the external IP of your VM as the first (ssh) host name and localhost as the second (SQL) host name. Input all other info as it is asked for.
First and Foremost, I know zip, zilch, nada, about VBA, access, and Advantage database Server.
I have a PC in one location that can connect and update with an Access 2010 file where every drive is mapped, e.g. \file\whatever
The advantage streamlinesql odbc dsn's were setup as such \file\whatever foxpro
Now, the PC has been moved to a new location (the company moved) and there is a vpn connection between the two locations (the data server is still located in the old location and cannot be moved), and so the new map would look like this: \xxx.xxx.xxx.xxx\file\whatever
However, Access cannot connect so that it can run its process and update the files it needs to.
I do not know the actual code to place here to help with fixing this, so answering this question with more is fine with me.
I can say that the vpn is built with sonic wall.
The first thing I would try is to connect with ARC32 (The ADS query tool), since you can then rule out ODBC and Access as the problem.
ADS has three connection types:
local
remote
internet
When you directly connect to an Advantage Database Server via TCP/IP, you want the remote connection type.
The connection type can usually be set via the ads.ini file, which also must contain the IP address and port for the ADS server:
[SETTINGS]
ADS_SERVER_TYPE=2
[MYDATABASE]
LAN_IP=10.20.1.20
LAN_PORT=6262
For more info about ADS.ini see the official documentation:
http://devzone.advantagedatabase.com/dz/webhelp/Advantage12/master_ads_ini_file_support.htm
When you try connection over ODBC maybe a complete reference of the connection options would be useful, I have written them down here:

I am new to Centura application configuration
When I try opening the windows client application, which has the Centura sql.ini configuration file. I get the below error.
Can anyone please help me understand the issue?
Error code: 401
Reason: FOR SQLBASE: The specified database cannot be found. SQLBase cannot find the file named "x:\dbdir\dbname\dbname.DBS" where x:\dbdir is either the default, c:\SQLBASE, or modified with the DBDIR SQL.INI configuration keyword. In a multiuser network configuration, this error indicates that your network is working correctly, but the database system was unable to locate the specified database filename.
FOR NON-SQLBASE DATABASES: This problem can also occur with a SQLGateway when leaving out the protocol type in the SERVERNAME parameter that the client uses to communicate with the gateway (like SQLNBIOS).
For example, SERVERNAME=SERVER33,SQLQUEUE DBNAME=DB2DBMS, SQLQUEUE, SQLNBIOS
will not allow a remote client process (using SQLNBIOS on the LAN to communicate with the SQLGateway machine) to connect to the SQLGateway machine.
For SPX connectivity from DOS or MS Windows to a Unixware SQLBase Server check for the omission of the "serverpath=..." parameter in the SQL.INI file under the client section.
Remedy: Verify the database file exists. The default drive letter and dbdirname is c:\SQLBASE unless overridden with a DBDIR SQL.INI configuration keyword parameter. Verify the DBDIR keyword is not missing or pointing to a wrong database directory. Verify the DBNAME keyword is specified for the named database. Verify the SERVER keyword is not missing or conflicting with other network server names. In your CONFIG.SYS file, verify at least 40 files set with the FILES=40 parameter. If the server was being initialized while the connection was tried, retry the connection after the server has initialized. If all of the above fails, try using a different database name or try connecting to the database in single user mode at the same machine. If you can connect with a local engine it probably indicates a network configuration error exists. If you can connect with a new database name it probably indicates a previously named database was never properly initialized.
I'm making a winforms app in vb.net that connects to a mysql database on my webserver to read and write data, this all works fine.
But i have to allow the users ip to remote connect to the database.
Is it possible to give everyone access to the database? The user account will not have all rights an the data isn't very important if it got lost.
The user account and connection details are hard coded.
I know this isnt secure but that doesnt really matter.
Yes, that's very well possible. In your mysql privileges table you'll have to grant a wildcard (%) host access to the user. Then in your VB.NET code simply use the address in the connectionString.
Yes, you can GRANT permissions on the database to the same user with wildcards in the host. More information here.
You can specify wildcards in the host name. For example, user_name#'%.example.com' applies to user_name for any host in the example.com domain, and user_name#'192.168.1.%' applies to user_name for any host in the 192.168.1 class C subnet.
The simple form user_name is a synonym for user_name#'%'.
That way every application connects to the database from random hosts and uses the same username/password in the connection string to authenticate, and MySQL will allow it because the host part of the permissions isn't explicitly specified.
But i have to allow the users ip to remote connect to the database.
Why?
Two other options:
1 - Expose the data as a web service. It's already on the web server...
2 - Build a web app instead of a desktop app.
